Hello Illinois Energy,

I can not say anymore about Matt and his partner. both men did an outstanding job and their work ethics are ones to be proud of.

Good company, management and workers is the best combination you can achieve.

Take care,

We met with Alex Haas of Illinois Energy in October, 2013 about window replacement. He was extremely knowledgeable and answered all our questions. We were impressed with his professionalism, the quality of the product and the excellent warranty so we decided to have 3 windows in our bedroom replaced. Up to that point we had many problems with the windows in this room. There was difficulty locking the windows, condensation, and the biggest problem-leaking. Whenever there was rain, we had to line the sills with towels to absorb all the water that was leaking. This also caused damage to the window sills. The windows were replaced in December, 2013. The installers were working in very cold weather, yet they took their time to make sure the job was completed properly. The windows look beautiful, they work smoothly, but the most important test came when it rained.. There has been no leaking and no condensation. We are very happy with the new windows and are having Illinois Energy replace more of our windows.
We highly recommend Illinois Energy.

Thank you Illinois Energy for the great job you have done making my house not only better looking but also more efficient. The workmen were very professional, they worked quickly, neatly and efficiently. It looks like I have a new house, I am very satisfied. Thank you again!

Dear Illinois Energy,
Illinois Energy Windows and Siding has been a pleasure to do business with. Our salesman James was very professional and full of industry knowledge. Having no real knowledge of windows prior to meeting with James I walked away with a true understanding of why Worthington Windows are a superior product and why Illinois Energy’s lifetime warranty is different than other lifetime limited warranties.
Working with James we split the windows into groups that will get installed incrementally. This is a more affordable option for us allowing us to pay in full rather than finance. Our home is only 10 years old but the windows the builder installed were garbage; drafty in the winter and rusted in-between the panes. Installation went smoothly; our installer was very polite and respectful. The windows were installed in a day and everything was cleaned and patched before they left. I would definitely recommend Illinois Energy Windows and Siding to anyone looking to have a superior product installed by professional s in their home or business. Our windows look amazing and perform as promised. We look forward to having the next batch of windows done soon.

We recently had Illinois Energy replace all of the windows on the main level of our house, 7 windows total and a sliding glass door. We could not be happier with the end results! Our windows went from a dark brown to a brilliant white and it is amazing how big of a difference the new windows make in our house. The new sliding glass door looks wonderful and all of our windows and the doors are so much less drafty! We immediately felt a difference! We replaced a bathroom window with a glass block window and it looks amazing! Such a huge difference it makes to our bathroom! Illinois Energy did incredible work and we could not be happier with our new windows! The people who we worked with from start to finish were the epitome of professional, from the salesman all the way through the process to the final walkthrough. We were just recently married and this was the first major upgrade we had made to our house and they made us feel VERY comfortable with their company and our decision to “take the leap” of investing in such a huge project. Every one of our questions was answered and they even went beyond and replaced trim halfway through the job that we decided we wanted to change! Our whole experience with Illinois Energy was wonderful and we are so happy with everything about their company and their products. We will definitely use them in the future for the rest of our housing upgrades!

Thank you!!

Hello Illinois Energy,

I wanted to write a note to let you know that I am very happy with the front door and the replacement of the screen door. I deal with customers on a daily bases and if a customer has a problem and you can fix it in a timely manner they’re still happy customers. That is the case with us. We had a problem with the screen door and Illinois energy was on the spot and got it fixed. I am a very happy with our door now and thank you for your service, and professionalism. I will definitely endorse Illinois Energy for people looking for Door and Window works.

Best Regards,

We recently had Illinois Energy replace a large bay window in our living room, the windows in our daughter’s room and our front door. We have immediately felt and seen the benefits.
Sitting in front of our bay window during the winter months was like an endurance competition because you could actually feel a cold draft coming over your shoulders. We tried loading the sitting area with blankets to block the encroaching elements, but all that did was give us cold blankets with which to cover our freezing selves. The new window was installed on a 25-degree day, and the change was incredible. Not only is the area warmer but it is also quieter because we no longer hear the breezes that used to squeeze through the old windows.
Our daughter’s room is also much quieter, and we can’t wait to see the difference this summer in the amount of climate control the room will have. Because her room is on the second floor and faces west, it used to be roasting by about 4:00 in the afternoon. We’ve already felt the difference in the amount of bright light that enters the room, so we’re confident she’ll sleep more comfortably when the weather warms.
But the most noticeable difference has been with our new front door system. Our previous door looked rather cheap when compared to the rest of the house, and the lack of sidelights made our front entryway dark all day long. In addition, you could actually see gaps along the bottom of the old door where cold when seep in. Our new door is rich in color, has a much more stately design and fits tightly in the space to help regulate the inside temperature. We live on a street with many beautiful houses, but we now feel that our new door helps our house stand out.
Installation was quick, courteous and professional, and we will have no problem recommending Illinois Energy to our friends and neighbors.

The Spellerbergs

When we first scheduled our appointment with Illinois Energy, we only planned to get an estimate for windows, and didn’t think we would be buying anything. However, after going over all our options with James we were sold and couldn’t wait to get new windows. James was extremely knowledgeable and explained everything in detail such as the quality and construction of the windows.

Shortly after, Dom came in to take all the measurements for the windows and we were extremely impressed with his knowledge and professionalism. After experiencing some difficulties with obtaining permits (the double hungs we wanted did not meet egress) James came back in to figure out an option we’d be happy with. Not only did we find a solution, but came up with something better than we could have ever imagined.

Installation was relatively quick and painless as well. Matt and Donnie did a fantastic job, working extremely hard to get the job done. The work they did included installation of 11 windows and 5 of these needed new cut-outs. They left the house clean and even painted where there was new drywall.

Overall, we love our new windows. The outside trim is absolutely beautiful, the views from the inside are stunning, and we have already noticed a difference in temperature in our bedrooms. We cannot wait to finish the rest of the house.

Dear Illinois Energy,
 We just wanted to let you know how pleased we are with our 2 new doors.  Its nice that on this very windy day, we no longer have to put towels around the doors to stop the breeze. As you know our doors were massive, and therefore, custom.  With Jim’s guidance and suggestions, we found the perfect match and enhancement for our replacement doors that fit well with the house’s design, décor and function.

 The process was easy from beginning to end.  We really appreciate the level of communication all through the process, keeping us well informed every step of the way.   The installation of our two doors was textbook.  The quality of the workmanship, the completion of the work in the time stated, the cleanliness and care of the work site and our home was very much appreciated. 
We wanted to thank you for everything.  
It was a pleasure doing business with an exceptionally professional company.

I would like to thank you for the outstanding job your guys did in making everything right. Mike and Jim both did an absolutley outstanding job and I am 100% satisfied with your company. Your guys took pride in the job itself and also your company. Please feel free to give my phone number to anyone who is considering your company as I would gladly tell them how happy I am with your products and service.

Thank you, JT

James Shropshire, Sales Manager of Illinois Energy came over and we discussed the company and their products. James knew their products quite well and he was very informative on products from Illinois Energy’s competitors as well. It was a very positive experience.
I do a lot of my own work and I thought I knew windows very well but, from listening to Mr. Shropshire I found out how much I really didn’t know. I was planning on buying and installing windows myself next year, but what I learned from Mr. Shropshire I decided along with my wife to have Illinois Energy do the work.
I can’t say enough about the quality of the window products and I’m sure the rest of their products exceed any other competitors out on the market. The only thing I could say negative if there’s anything negative to say is my wife and I both thought the price of the windows were much to high, but with the warranty of lifetime replace and or repair the price seems fair. If Illinois Energy could do something to lower the price somehow I believe they would leave the competition behind.
The windows we ordered were actually custom made for us and not sitting around in some warehouse gathering dust. I found this quite unique. Our windows were ready in four short weeks and I was called to let me know they were ready. I was busy the next few weeks at work so I couldn’t schedule for Illinois Energy to come out and install the windows. Illinois Energy worked with me and actually scheduled the install on Saturday. The installers arrived on time and were very accommodating and courteous. They completed the work of installing the windows in less than a day and cleaned up all the debris inside and outside the house.
The windows are just beautiful and match the décor inside house as well as the outside which they finished off on the exterior of the house with matching trim. They also caulked all the windows on the exterior of the house. The installers were quite thorough in installing, caulking and cleaning up after the work was completed. I would recommend Illinois Energy very highly due to the quality and workmanship of their window products and their representatives. It was all such a positive experience.

Dear Michael St.Claire Sanchez,
Tammy and I are so happy with the way our windows and door turned out. They give a fresh new look and feel to the whole house.  We can tell how well they insulate and keep in the cool air during the summer and how warm they help to keep the heat in during the winter season. I think I liked the new exterior door the most.The wood grain option to make the door match the rest of the wood trim indoors looks really awesome!
The installation guys were real profesionals at their work and were prompt and courteous. Although the installation time was around a holiday weekend they did the best they could to finish most, if not, all the work in a timely manner. Thank you so much for an excellent job with our home and if Tammy or I know of anyone in need of some windows or doors we will be sure to recommend Illinois Energy to them.

Sincerely, Cesar and Tammy A.

Hi Illinois Energy,
I wanted to tell you how pleased we are with the work that was performed. Amy & I have had nothing but positive things to say about the project. As you already know, we originally chose Illinois Energy because of your sales staff. James really set himself apart from your competition by not just selling the quality of your product, but by creating a connection with us personally. Clearly making a sale was important, but he took time to listen to us and our needs and although he didn't walk out of our house with an immediate sale, his flexibility and support helped us to arrive at the right decision. Ultimately that decision was Illinois Energy. In addition to the nice work by your sales team, the installation crew was top notch. From the moment Jim arrived, we were impressed. He was professional, personable, and efficient. The work team did a great job of keeping our house clean. Without the need for us to ask, Jim & his team were consistent in removing their shoes when working in the house (even though there were a lot of trips in and out due to the nature of our project). The respect for our house was appreciated. In addition, the installation team was probably one of the most efficient & hard working that I have seen. From the moment they arrived to the moment they left, they were working. They did not take breaks & barely stopped for lunch! They were flexible with the village inspector and worked around his schedule as well. And although they were busy working while they were here, Jim was very friendly and was more than happy to answer any questions Amy or I had about the work that was being performed. As for the windows themselves, we think they look beautiful (both inside & out) and what a difference they made right away. The sound dampening is fantastic, but even better was the difference it made in keeping our heat in the house! We are very satisfied... which brings me to the second topic.  And as a quick side note... although I didn't mention it above, I couldn't have better things to say about your part in this process as well. Rarely do you find the owner of a company who is willing to get as involved in customer satisfaction as you have been. Your responsiveness has been fantastic, your willingness to involve yourself to ensure we are satisfied has been great.

Thanks again & I look forward to hearing from you and hopefully working with you again.

"We wanted to tell you that we are thrilled with our new windows and doors. They are beautiful! We don’t want to cover the windows with treatments, and we have gotten several comments on our stunning front door. The large picture window practically brings the backyard into our family room, and the beautiful beveled glass inserts in the new front door and sidelights let natural light shine through to brighten the entryway. We’re looking forward to being warm and cozy this winter as we enjoy the view of our backyard without the drafts we used to feel from our old windows and front door. The quality of the products is apparent in the fit and finish of each one. The windows and doors match our wood trim so well. It was a bonus that we didn’t need to replace the interior trim on many of the windows that were replaced. We want to thank you for everything. Everyone we’ve dealt with from Illinois Energy has been professional, friendly, and knowledgeable. The work crew was polite, timely, neat, and unobtrusive. The crew delivered quality workmanship and did an excellent job with the carpentry work to adapt some of the window openings.

"We love our new windows and siding -- Snug and warm against the chill of January and February. Thank You again for a Top-Notch Job."

- M.W., Naperville, IL 60565

"We ran our air conditioner for the first time this summer and it literally cycled half as much as it usually did. That is a great improvement. Thanks again for all your help."

- C.A., Mt. Prospect, IL 60056

"Just a note to tell you how much we enjoy our new windows. We love how they open to wash them and my nephew said he never saw a neater job of caulking. I would recommend these windows to anyone. Being a senior it's very easy to take care of them. Thank you so much."

– Doris C., Bolingbrook, IL 60490

"I am writing this letter to let you know how pleased we are with our new windows. As we walk through the house or sit by the picture window, we marvel at the fact there are no drafts and the house stays warm! At night, as the spring winds have begun to blow, there are no rattling storm windows! We are confident we will be saving on air conditioning this summer, too. Oh yea, it will also be nice to have no June bugs and fewer lady bugs in the house! As for service, we were more than pleased. The whole job took only a few hours, and the installers were very concerned with keeping the house clean, inside and out. Thank you also for accommodating us with the changes we wanted to make after the fact. That was going above and beyond what was expected. your personal involvement in the service we received says you are about what is, to us, a major investment."

Sincerely – Diane B., Libertyville, IL 60048

Dear Illinois Energy,

I want to share information to others about your company.  My husband and I want to thank you for the wonderful service.  About two years ago we purchased windows, and we are very impressed with the installation and service on our windows.  A few days after the install, I became aware of a situation with one of our windows.  I immediately called and within two days an installer came to our home.  Needless to say, there was not a serious problem, but fixed the situation "on the spot".  I am completely impressed by Illinois Energy and happily satisfied by your generous discount given.  


Rachel L, Cary, IL

"We wanted to thank you and your crew again for the high-quality job that was done on all of our new windows and doors! Our house just turned 50 years old and it still had most of all of its original windows. It is quite a difference with the new ones. No more peeling and cracking paint! No windows that are sealed shut! No more changing out the outer storm windows for the summertime screens! And most-importantly, no more drafts and excessive heat exchanges! We ran our air conditioner for the first time this summer and it literally cycled half as mush as it normally does. That was a great improvement! I'll expect the same results this winter. The bow window is the kitchen actually lets in more light than the flat window that used to be there. Which is ideal for a north-face window. The new doors look great too and provide a much-needed seal as compared to the old aluminum doors. The crew was great! They did a 2-day job in less than a day and cleaned up very well. The walk-through went well too. Thanks again for all for your help. I'll highly recommend Illinois Energy Windows & Siding to anyone who needs replacements like I have."

Sincerely – Chris A., Mt. Prospect, IL 60056

"Thank you so very much for replacing our windows. We found your salesman very professional and informative about the replacement and ordering of our windows. We didn't have to wait too long before our windows were manufactured and then installed. Your installation staff were very pleasant and efficient. The windows look wonderful and match our wood work perfectly. I would definitely recommend your company to anyone who is looking to replace their windows or have their exterior replaced. We are very satisfied customers in the whole process, and e appreciate all your hard wok to make this a pleasant and painless experience!"

Thanks again – Joel and Samantha A., Oswego, IL 60453

"Just a short note to let you know that our new windows are great!!!!!!!! Tom and I cannot believe how much warmer our house is. We also are excited by our reduced heating bill we jut received from NiCor. Compare to last year, we are using less gas to heat our home. In a year of rising heating cost, we have found our bill to be much lower than any o our neighbors. In prior years, we have had the highest heating bill. NiCor even went so far as to reduced my monthly budgeted amount from $246.00 to $56.00. Thanks so much for the great service and the wonderful product!"

– Carol M., Naperville, IL 60565

"We absolutely love our new Castleview Front Door! Our house now has much better curb appeal than before. Our neighbors have all noticed and told us how great the new look is. Dave did a great job helping us select the right door and side lite. The installers and Dominic did a great job making it look and work perfectly. It feels great coming home and walking through our new door every day after work."

Adam C., Naperville, IL 60564

"As satisfied customers, my husband and I wanted to let you know how much we appreciate the manner in which Illinois Energy has treated us. A special thank you to violet and David for taking the time to order extra supplies at a rapid pace. Illinois Energy put new siding on oue home in 2002, and we are in the process of installing 2 doors which needed extra siding and "j" channel to complete the project. We also needed a light block for an exterior light. Violet and David were very prompt in returning my phone calls, as well as getting the supplies we needed at no charge to us. Thank you for your quality customer service. We will continue to refer neighbors and friends to Illinois Energy Windows & Siding."

Sincerely – Edward and Tara D., Lisle, IL 60532

"We moved from Mt. Prospect to Deer Park. I really miss my windows and doors! We will be

"Dear Illinois Energy Windows & Siding, Our windows and patio door look and function great! We appreciate the efforts of Sales (Sam SanFillipo did everything he said he'd do to make the job flow smoothly) Installers (Dave, Tom, Ken – Professional, precise work. Service (Dominic – Took care of detailed items for our 100% satisfaction.) Thanks again to the Illinois Energy team."

Much Warmer – Lou R., Westmont, IL

"I'd like you to know how pleased we are with the job your company did replacing our windows. Our old single-pane, double-hung windows were rotten and rickety. The old aluminum storm and screen sash system didn't have weep holes to let the rain water drain out the sills. As a result, the sills became, rotten and Some of the windows actually sagged out-of-square. The installers did a great job. They fixed or replaced the rotten sills and squared-up the framing with sound carpentry practices before-installing the replacement windows. As an architect, I appreciate the steps they took to keep the weather out forever. This time, I know the windows will last. The Window units themselves are great and make each room more comfortable. We no longer feel drafts and our house is now much quieter."

– Ron & Karen H., Wheaton, IL

"It has been a week since we had Illinois Energy Windows & Siding install new windows in our home and I want to take this opportunity to say what a wonderful product your Worthington windows are and to say Eileen and I are very pleased with our purchase. They are everything you said they would be. We have noticed a considerable noise reduction and the house stays warmer longer since they were installed. They really seem to make a difference. Plus, I'm glad you talked us into the almond color for the outside part of the window. They really stand out and it is a wonderful contrast to our dark brown siding. Tom and his crew who installed the windows did a wonderful job. They were all very personable, professional and meticulous in getting every detail done right the first time. They took their time to cover all area's inside the house where they were working and they cleaned everything up after themselves. You would not have known anyone did any work. Please thank them again. Your windows have improved the look of our home both inside and out. They are a superior quality window and I don't believe any other window installer has the outstanding warranty that your window's have. That was a big selling feature for us. I would highly recommend your product to anyone interested in purchasing new windows. They are far and away better then any others I have looked at! Sam, your presentation was very thorough, informative, and enjoyable. I believe we made a wise investment in purchasing Illinois Energy windows. Again, thank you for making our decision an easy one!"

Sincerely – Vern & Eileen Z., Tinley Park, IL. 60477

"As you know, we recently had all of the windows in our home replaced and wanted to let you know how much we appreciated all the hard work and effort that your employees devoted to the completion of the project. From the beginning to the end, from the sales representative to the installers and carpenters, everyone showed their commitment to upholding your company's professional image which is reflected in the quality of your products. We especially appreciated the extra work of your carpenters in solving some problems with water damaged wood that had to be remedied before some windows were installed. Your employees were courteous, communicative and on time, exemplary traits that will give us no cause to hesitate recommending your company to our friends. Thank you, again. We are very proud of the appearance of our home with the new windows."

Very truly yours – Steve & Sue D., Naperville, IL 60563

"Gentlemen, Thank you so much for doing such a great job on our house. The siding makes our house look brand new. Also, thank you for being so careful around my plants. Some of those plants belonged to my grandparents and I wouldn't be able to replace them. I really appreciate your high level of professionalism."

Sincerely – Steve & Shan H., Hoffman Estates, IL

"We are very pleased to write this letter of recommendation for Illinois Energy Windows & Siding Inc. We had all of our windows, siding, soffit, fascia, and gutters replaced in December 2008. Every aspect of the project was comlpleted to our satisfaction. Each member of the Illinois Energy team, from the Sales and Advertising Managers to the installers, very professional, courteous, and knowledgeable. This was the largest renovation project that we had ever completed on our house. So, naturally we were very particular about every little detail. Our house has been transformed. We couldn't be happier."

Sincerely – Scott and Gail A. Frankfort, IL.

"I wanted to let you know that the crews you had at our house to install the windows and vinyl soffits we purchased did an excellent job. They were true craftsmen and paid very close attention to detail that resulted in a high quality job. They were timely, friendly and did an excellent job of cleaning up at the end of each day. Overall, we were very satisfied with the work they did, and would not hesitate to have them work on our house again."

Sincerely – Mike and Jeanne B., Crystal Lake, IL

"In the summer of 2008 I purchased front windows, a new front door and a new patio door from Illinois Energy. The representative, James Shropshire, was professional, informative and genuine. He provided very clear information concerning the specific costs of my windows and doors. James provided adequate time and was patient in answering all my questions. The workmen came in, did their job professionally and were very respective of my home, wearing booties when walking on carpet and cleaning up after themselves. They were very good. My doors are absolutely beautiful. The windows easily open and close and my sliding patio door slides very easily. Thus far, I would highly recommend Illinois Energy Windows and Siding for windows and doors."

Sincerely – Carolyn B., Carpentersville, IL

"Thanks again for the windows. My wife and I cannot stop talking about the quietness around the home due to the windows. We can open the curtains again because we no longer feel drafts standing near the windows. We can see out of them without condensation blocking our view. I am sure that when the bills start coming in we will end up saving lots due to the efficiency of the windows. We also want to praise the work crew for their fast and expert installation of the windows. It was right before the deep freeze we had, in the Chicago area, and we were a bit concerned about the time it would take replacing our old windows, but as we were promised it was less then a days worth of work and they cleaned up well after they finished. We are very glad we choose Illinois Energy for our new windows and when we look to replace our old siding we will keep you guys in mind."

– Kermit & Janine E., Bartlett, IL

"We are writing to let you know how satisfied we are with our new windows and sliding glass door. They all look beautiful! The installation was quick and efficient and the staff very courteous. The windows are a breeze to clean and when we requested a service call, your staff was very responsive. We look forward to years of reduced energy costs and greater savings with our new windows."

Sincerely – Michael & Kelly D., Aurora, IL

"My windows were installed yesterday and they are awesome!! I couldn't believe that 4 installers came to do 5 windows I've never seen such a thing. Usually there is 1 installer and it takes all day. Wow! As my husband and I were admiring the windows we saw a defect. I called with that information today and someone will be looking at it soon; your company is very diligent. As I said before, your company has set an example for others to follow. Thank you again for all the time you've given me, and have a wonderful day."

– Gary & Rachel L., Cary, IL

"Although our house isn't all that old, we were in desperate need of new windows. On some of them we would notice wind blowing through them or condensation (ice/moisture) would gather. Because of this we also determined that we were probably over spending on heating and cooling our house. We decided to go forward with installing all new windows, doors and outside shutters on our two-story home. They were installed over one weekend with little disruption to us. It was a very smooth process. Over the next couple of weeks our doors and shutters were also installed.
Since then we have been very pleased not only with the look of the windows, doors and shutters, but also with how we have been able to adjust our heating. Last winter, om thermostat was usually set to around 73 or 74 degrees. This winter we have been able to lower it anywhere from 3 to 5 degrees depending on the weather. Our house just feels tighter. We would happily recommend Illinois Energy to anyone interested in installing new windows. We were very pleased with the level of service from the sales representative to the installers to the owner who called us personally. He thanked us for choosing Illinois Energy and told us his company would do the job until we were 100% satisfied. They are a great company with which to work."

Sincerely – Todd and Shannon K., Wheaton, IL

"My wife and I wanted to write to let you know how pleased we are with the new windows manufactured and installed by Illinois Energy. The windows are great looking and easy to use. We have already noticed how much better our new windows insulate us from the cold.
I was home during most of the installation process and want you to know that your installation crew was extremely professional and hard working. They were respectful of our home, thoroughly cleaned up after themselves and provided clear explanations to all my questions. We will certainly recommend Illinois Energy and you to our friends and neighbors. Thank you again for ajob well done."

– William M., Aurora, IL

"Let me just say right off the bat that we are thrilled with the work that your company had done on our home in Cary Illinois. Our house actually has curb appeal now!
We chose Illinois Energy Windows & Siding Inc. in the first place because the salesman (Dave Sullivan) who came to our home was extremely knowledgeable and helpful. Seeing that we have two kids going off to college in the near future we had to stick to a budget. In no way did Dave try to talk us into something that was out of our budget rage. He answered all of our questions to our satisfaction. The next day when we realized that we had a few more questions we called the company and the company was quick to respond - again to our complete satisfaction! After a quick check with the Better Business Bureau we decided that Illinois Energy Windows & Siding Inc. in all probability knew what they were doing. We knew that this was the company we wanted to do business with. Between the estimator and the workers, they did a great job. They were very polite respectful, attentive to detail and very understanding of our two rambunctious dogs as far as keeping the gates closed. At the end of each day the yard was cleaned up and any ladders or material were placed where they did not interfere with our comings and goings. Once they started the job my husband and I were so impressed with the workmanship we even requested more work to be done on another part of the house. We believe that is company's service has been more than satisfactory. We are very comfortable recommending Illinois Energy Windows & Siding Inc. to our neighbors and friends."

Sincerely – Todd & Sue L., Cary, IL

"I just wanted to Iet you Know what a difference getting these new windows has made in our home. Before getting Illinois Energy windows, I was afraid to let my newborn son sleep in his room. With his old windows, there woulld be mold in the Springtime and ice in the Winter. His room was constantly drafty, and the screens were so loose that I was afraid if someone leaned on them, they would pop out. When Illinois Energy presented us with a great offer for their windows, we decided to change our windows. From the first moment, we have had courteous and knowledgeable staff that was able to answer all of our questions. All of our experience with Illinois Energy Windows & Siding has been great! The staff has been fantastic, and efficient. Once the windows arrived, they were installed immediately and professionally {we would know because my husband is a carpenter). I appreciated the time and effort that the employees put in to make us feel comfortable with our purchase. I was impressed on the careful effort the employees took to respect my home while working. They made sure that they cleaned up after any work they had done. I would definitely recommend them to anyone. Now I can relax with my son sleeping in his own room, but the windows look great as well! If you are concerned about the safety or health of your family because of your current windows, or just want to upgrade to a better looking, more efficient window, I would definitely consider Illinois Energy for your home. Thanks so much!"

"10 years ago Illinois Energy did a whole house replacement windows job for my father-in-law. He like the windows and has never had a problem. Now that we need windows, we called Illinois Energy, as we know the high quality of your windows. Garrett Hayward came to our home. We are very satisfied with the price and product."

We just wanted to take a minute to thank you again for the great job the whole Illinois Energy Team did on our windows. Brian – thanks for the great ideas for the casement and awning windows that made the windows look and work better. Tom and the installation crew were very professional, extremely neat and did a great job fnishing all the details on the windows. A lot of neighbors have stopped by to tell us how great the windows look, and we are really impressed how much better our home’s curb appeal is now. It’s great to smile every time we come home and look up at the new windows. What we did not expect is how much better our view looking out is! The new window that was installed in the office has greatly helped let in more light to a room that needed some brightening. Not to mention, we no longer have drafty windows, they are all tightly sealed. We’re definitely looking forward to lower energy bills and spending less on A/C and heat. Thanks again for a great job by everyone involved, we are very happy with the results, and will gladly recommend you to our friends and neighbors.

"Margie and I would like to thank you and express our thoughts regarding Illinois Energy Windows. Although we were not in the market for windows. We allowed you to come in our home to demonstrate this wonderful product. We knew that our windows were not very good and someday we would have to make a decision on replacing them. Well, we took a chance and decided to order a couple of windows and we are very happy with our decision. The windows did not only enhance our home, they also eliminated the draft that was coming in through our existing windows. The installers were very professional and may I add, very quiet and neat during the installation and they were done in a timely manner. We are very happy with the results and look forward to doing business with you in the future."

Dear Illinois Energy,
"We wanted to take a minute and write a letter saying how happy we have been with the work that Illinois Energy did on our windows and door. We had major problems with our existing windows with leaks and condensation between the panes. When the wind would blow, we could see our curtains move. It was both embarrassing and costly with high energy bills. Illinois Energy came out and assessed our windows and gave us several options as to how to go about replacing them. We were unable to do all of them at once, but Illinois helped us come up with a plan that was both affordable and addressed our biggest concerns first. They also helped us choose a new front door to replace our current one which was letting in a lot of cold air also. When the workmen arrived, they did a wonderful job removing and replacing the windows. They took great care when cutting the old windows out and putting the new ones in. They replaced 8 windows and the front door in a single day. They were very organized. They took the time to show me everything they were doing and made sure that if I had any questions or concerns they were answered right away. When the project was complete, they walked me around and had me look for any problems. They showed me how the windows worked. They demonstrated how to clean them. That was one of the best features we have in these windows, i.e. the ability to clean both panes from the inside. We no longer need ladders in high winds at 30 feet off the ground. That is not to say the job went completely perfect. When the front door was installed, it was discovered that Illinois Energy did not order the new door knobs. They had to put the old one on temporarily. However, they called it in right away and called us as soon as it arrived in their shop. They scheduled the service technician to install it when it was most convenient to our schedule. Not only did he replace the old door knob, but he replaced the hinges to match the finish of the door knob. It is little things like this that made the experience of working with Illinois Energy satisfying. We appreciate Illinois Energy's customer service. The day after we signed the contract with Illinois Energy, the owner called us to thank us for our business and let us know that we could contact him at any time if we had any questions or concerned. When we did call him after that, he was always available to talk with us and address our concerns. All other employees (Le. salesman, foreman, secretary, carpenters) were always courteous. They worked around our schedule and were very understanding when we had to reschedule a meeting. I've worked with a lot of contractors on my job. They typically are very concerned about getting the work done quickly so they can get paid and are not concerned about doing a good job. Illinois Energy was not like that. Their number one concern was our happiness. They did not expect payment until the job was done to our satisfaction."

Peace of mind, quality work, and excellent follow through come to mind when I think of working with Illinois Energy Windows and Siding. Thank you for the wonderful experience while having new siding installed on my home! From the first possible design discussions to the detail in each finishing touch I was met with knowledgeable professionals leading the way to excellence. Of all the various home maintenance companies I've encountered in 25 years of home ownership, Illinois Energy Windows & Siding, Inc. rank among the best in all areas... attention to detail, timeliness, and quality of product. The warrantee and financing option was rather impressive as well. My home now has 'curb appeal'. I can't wait to see how much I will save on my heating bills! No more painting ... yippee! It is with deep satisfaction with my project, that I do not hesitate to recommend Illinois Energy Windows & Siding, Inc. to anyone needing this type of work.

Illinois Energy, Mr. Sam F,

Thank you for this opportunity. The windows are amazing. It is great to have locked in the price. Your installers and sales people are so considerate, very neat, and informative. Just waiting for someone to stop and ask about the sign in yard, so I can show the the quality and professionalism. Thanks Again.

Thanks to your quality workmanship my house now has improved curb appeal, improved energy efficiency, and is more animal resistant.  I am completely satisfied with the job. The new siding makes the house look cleaner and more modern, especially from the backyard.  The shakes Michael recommended for over the garage look even better than expected. The primary reason I had the work done was to increase energy efficiency, I feel confident that has been accomplished.  By replacing two patio doors with four-panel, custom built ones with insulated glass, Martin and Adam from Kamil’s crew did an outstanding job.  The panels were irregular in size.  The poor condition of the existing frames required lots of attention to detail as one of the original parts could be salvaged.  Extensive insulation and caulking complete the job.

For several years, my house has attracted a variety of animals, particularly raccoons.  When Roman removed the old fascia we discovered why – wasps.  Dozens of active hives existed in gaps between the old fascia and the brick building.  In addition, when he removed the cedar boards from two, 18-foot peaks, lots more wasps appeared.  The inside sections were open. The area inside had not been insulated, nor any plywood installed.  The raccoons were seeking shelter and wanted to eat the eggs from the nest.  While roman worked another part of the house, I had an exterminator eliminate the wasps. By replacing the cracking cedar panels with snug-fitting vinyl siding, my house will now be less attractive to critters and be more energy efficient. Your workmen were professional:  polite, on-task, and neat.  They performed their duties without loud music and unnecessary noise, and added treat for the neighbors.  I recommend Illinois Energy without reservation to any homeowner needing widows, siding, gutters, or downspouts.

Thank You,
Theresa W., Western Springs, IL

Dear Illinois Energy,
We just want to let you know how overwhelmingly happy we have been with your company, your representatives, and your product. When your sales rep, James David, knocked on our door a couple years ago, we were already looking at buying new windows but were only considering "name brand" companies. After listening to what James had to say, and seeing the positive feedback at the Better Business Bureau website, we decided to purchase new windows for our entire house through your company. We have not regretted it at all. One thing we really appreciated about your company was the payment options. At the time, we had a newborn son and money was tight. Allowing us three years to get all of the windows installed at a set price was what ultimately swayed us to give you our business. The windows themselves have been fantastic. They are durable and easy-to-use - definitely a step up from what was previously in our house.
Recently, we decided to finally finish the rest of the windows in our house. Once again it was James who stopped by to take measurements and meet with us. It was good to see him again, and we not only think he is a terrific guy, but an outstanding representative for your company. I can say for certain that our trust in James helped make our decision to purchase new windows one we didn't regret. 
We have had an outstanding experience with your company and will certainly, absolutely and without hesitation recommend your company to everyone we know.
Thank you,
Mark & Danielle A.
