We have used Illinois Energy on three separate occasions for upgrades to our home over the past several years. The Sales team and installation team are friendly and very helpful throughout the whole process. They are highly recommended.

Five stars. Illinois Energy Windows & Siding installed all my windows to standard and followed up to make sure I was happy. They are a bit pricey, but the quality and the strong warranty make it worth it. Reputable company with many years in business and I am very satisfied.

Paul was very detailed in a way that made things go by quickly. The way he described the process is how it happened. The installers were on time and very quick with the installation while leaving the area neat. The doors were installed recently, so we will update if anything changes, but they operate smoothly so far. There is a short period where they are a bit tight after being installed, but then they are easier to use.

We had a great experience with this window installation. It took less than a day to install (4) windows and the installers were professional and courteous. The windows look and work great. I would definitely recommend.

Front to back, the experience with Illinois Energy was wonderful. Our sales rep was considerate and kind (we had the kids running around like crazies). he was not pushy, and offered really great options that fell inside our budget. Installation was FAST, and the installers were very considerate of my home. It was really a wonderful experience, and one that we will seek out again for further work on our house!

After we visited the IL Energy Window and Siding showroom, we purchased a new sliding door to our deck and, somewhat later, a new front entry door and sidelight. Besides the obvious quality of the products, the straightforward presentation by the sales representative, with no pressure and no blanket criticism of competitors products, was what sold us. We love both the sliding and entry doors. The glass in the sliding door did not radiate the cold air during bitter winter days, as our previous door had done. The entry door is just recently installed, but the look is modern and clean-lined as we wanted and the installation was impeccable with an impressive level of attention to detail. We are pleased and proud of our choices.

Recently Illinois Energy Windows & Siding did a fabulous job installing a bow window, along with a few standard size windows in our home. The installation crew was quick and did a wonderful job cleaning up after themselves.

We are repeat customers of IL Siding &Energy and will continue to be! We had our front door done and it changed the whole feeling of the house - it looks so much better and they took the time to repair/replace the framing as it was rotted more than we knew.

"Thank you for being a loyal customer! We're so glad to hear that your new front door made such a big difference and that our team was able to address the hidden issues with the framing.

Illinois Energy has installed / replaced 12 windows in my home. The last 3 windows were completed this year on the back and side of the home. They were on-time and completed on schedule. The windows are energy star rated, custom built and installed with very competitive pricing. The price I paid matched the quote and come with a guarantee while I live in the home. It is good to know that Illinois Energy has your back.

We were hesitant at first to make such a huge purchase, but we realized that the warranty coverage was the best out there. We were told someone would come measure the door opening and then they would call when the door was ready to install. We never saw the measurement guy, he came when we were not home. We just received a call saying it was complete a month ahead of schedule (reason for 4 stars). I was a little apprehensive when Jerry arrived (early, which was great) as he was by himself. I didn't think one person could do all the heavy-lifting on his own, but he did and did a spectacular job on top of it! We had an Anderson Door that was not installed properly and over time it was nearly impossible to open. the new door glides right open with very little pressure. I no longer need to lift weights to get my door open! Jerry did a gorgeous job on the inside and outside trim. He did a miraculous job covering up the sloppy trim and caulk of the old work. It looks so professional!
Response from Illinois Energy Windows & Siding Inc
"Thank you so much for the kind and thoughtful review! We're thrilled to hear that Jerry exceeded your expectations and delivered such a high quality result. He truly takes pride in his work and it's great to know his efforts made such a noticeable difference. We understand how frustrating that old door must have been and we’re so glad you’re now set up for a stress-free, easy-gliding summer. Thank you again for your business and support!

We recently had a fantastic experience with Illinois Energy for our new door installation. Choosing our door with the sales representative was simple, informative, and seamless. They took the time to guide us through the options, making the whole process stress-free. The installation was excellent – high-quality work that truly stands out, and our new door looks amazing. We couldn’t be happier with the results. We will definitely be using Illinois Energy again when it’s time to update our front doors. Highly recommend them for anyone looking for top-notch service and craftsmanship!

We purchased windows for our house and the process was very easy. The entire staff was great to work with from signing the documents to completing the installation. The crew was terrific. They treated our house as their own, cleaning up everything both inside and out. The crew even had to contend with one of the window openings needing to be adjusted for size. They crafted a new fitting complete with new casing and even painted it with the paint we had. We would highly recommend them.

"Thank you for the great review! We’re so glad to hear the process was smooth from start to finish and that our team made a strong impression. It’s always our goal to treat every home with care and respect and we’re pleased the crew was able to handle the custom window fitting to your satisfaction, even down to the paint!

We had an amazing experience with Illinois Energy and Siding. We had a sliding patio door installed and it is beautiful! The quality and attention to detail with finishing touches exceeded our expectations. From meeting with Derek, the salesman who was very knowledgeable and prepared to discuss the product, was easy to talk to and, was very patient with any and all questions we had. To Jerry, the installer who is one of the hardest working craftsman we have ever encountered! He was promptly on time, kind and gracious in our home and went above and beyond to help fix an area in our house that we were not expecting. We cannot say enough great things about Illinois Energy and Siding and we definitely recommended them and will be using them in the future.
Response from Illinois Energy Windows & Siding Inc
"Thank you so much for the kind words! We're thrilled to hear that your experience from your first meeting with Derek to the installation by Jerry was such a positive one.

The door we recently got installed by IEWS looks amazing. It gives the house a updated look. We had a great experience with the sales person explaining the process the options and helped us close the deal. We ended the purchase experience feeling great with our investment. We also had a great experience with the installer. He was very attentive to our needs and was very focused on making sure we were satisfied with the outcome. I highly recommend IEWS, 10 out of 10!

The whole experience was amazing. The consult and quote we did on a Saturday with my kids all running around. James was patient and so nice to work with. They measured all the windows the next day or two and The windows were ready in three weeks after signing. The day of they showed up on time. The whole process took 4.5 hours. Five guy team for 11 windows replaced. They put carpet protector everywhere and cleaned up everything. They had to cut trim on front of house to get old window out however the trim they put back that encased the window looks great and like it was built that way. I have wainscoting under a window and was worried it could be damaged and they did a fantastic job replacing the window. Nothing dented or scraped. They made sure Everything was perfect before leaving. They even ran through all the functions of the window again after they were all installed. The outside was cleaned up after as well. There was nothing for us to do other than sit and watch and ask questions, which they were more than happy to answer. We love our windows and felt a difference in the heating of these rooms THAT night. Great windows - great service- great price. Will definitely be using them again!
