Very thorough and careful. Did the job in the amount of time specified. Friendly workmen who kept me updated of any problems or concerns. IL Energy staff are also friendly and concerned that the customer is satisfied with the product and workmanship. They stand behind their product.

Illinois Energy Windows & Siding, Inc. removed an existing window, cut through brick and installed a sliding glass door in my home. They were easy to work with. They were professional. Everything was completed in a day. Now I have a much more beautiful dinning room with more light and a full view of my private backyard. Thank you for all you did on this project. I highly recommend them.

We have used Illinois Energy for our windows, siding and new front entry (door). We went with the top-level kit for the windows and siding, and a mid-level front door. This has transformed our house! Windows were the first item replaced: Prior to the new windows, we could hear every bit of wind or storms, and the dog would be hiding to get away from the noise. With the new windows, that noise was significantly reduced, so much that our dog no longer notices the wind. The windows are high quality and we had only one minor issue, and that was corrected as soon as we notified them. The windows come with a lifetime warranty that even covers damage to the windows. We have already had our screen door (installed with a patio door) repaired twice, both times due to humans or dogs trying to walk through the door. This company stands by their products. Our siding was done about two years after the windows. The same salesman came, and we worked out our deal with Tristan, we like working with him. It was expensive, but we have a 3K square foot house and a two-car garage. We also went with the upgraded siding that has insulation built into the siding. It’s thicker and each of the lines in the panel are larger than the standard siding. One note on the upgraded siding, the attachments for external openings like lights, hoses, etc. don’t work as well with the upgraded siding as they seem to be designed for the regular stuff. It took some added attention to get these done correctly. That said, with any project you need to keep your eyes on the details and be sure they are willing to correct issues. We had a walkthrough with a representative and they sent a crew out within a week to address the items we listed. I’m confident they will come back if something else catches our attention. Our house was built in 1985 and did not have a waterproof wrap on it. When they did the siding, they added that, a Tyvek like material. We also had multiple rotted boards in our soffit and facia, which we had them fixed as part of the work. All that extra wood took time to replace, but it was well worth it. So where are we now? The house has once again transformed. We no longer hear wind under 40mph, and even the big winds are barely noticeable. Our house is so quiet now, it’s strange. To think we could have done this years ago! We just had the 2024 June heat wave, and our house now keeps the humidity out so much better, and I think the AC is running less, to be confirmed with our next electric bill. Overall, we are extremely happy we did the siding project, it’s a game changer for house livability. Our last upgrade was a new entryway door. Our prior was a steel double door that was a bit drafty and not very nice to look at. Because of the newer building code we had to go to a wider single door, but we probably would have done that anyway. The new door is fiberglass and is very nice. Yet more insulation added. We had also replaced the shutters and the new door went well with them. With these projects we basically transformed our house. The looks, insulation and soundproofing are better than I’d expected and make the place so much more livable. Based on what we’ve seen from the windows (no sign of aging issues in two years) I expect the siding and door to have long lasting quality as well. I won’t say there were no hiccups, but we’ve had a lot of projects done over the years and there always seem to be communication issues between management and the actual installers. We saw a few, mostly when people would turn up differently than we expected on a couple of occasions. But regardless of that, a call to the company is always returned and the issue is acted upon. I have a lot of faith in Illinois Energy doing right by us. So far, they’ve delivered everything they promised, and the quality of the product is excellent. Their warranty is better than any I’ve seen, and we’ve seen it in action. The company is always responsive to our issues. I will ask for an estimate from them when our roof needs replacement in the next five to ten years.

Great experience from initial sales discussion, through scheduling and final install! Our salesman Paul was very knowledgeable, helpful, and direct in his initial meeting and provided quote. We had a personal event we needed to schedule install around and they worked with us to get them in much earlier than the estimate window. We had a smaller project – 4 windows installed but the installers completed the job in under 4 hours and left the house extremely clean. We will definitely be using them again in the future!

I have used Illinois Energy Windows & Siding twice – once last year to replace my front window and door and once this year to replace all the remaining windows and the patio door. The salesperson was extremely helpful and provided me with all my options and ways to save money. The installation was right on schedule for the front door and window, and about a month ahead of schedule for the rest of the windows. The installers were on-time, fast and efficient (a combined 3 days only to install 12 windows, a front door, and a patio door) and they went above and beyond in replacing rotted boards around the front door. There were a couple minor issues that were quickly and easily addressed, but nothing to prevent me from the rating I’ve given. Overall, a great experience.

Ten years ago we contacted Illinois Energy to have them install the windows in the front of our house, replacing wooden frames with their strong vinal and remodeling our front door entrance. They did a beautiful job. We recently invited them back to replace three smaller windows that we forgot to include back then. Their pricing and guaranteed support, and immaculate cleanup were appreciated. We’ll call again when we decide to replace our gutters and roof.
