Illinois Energy Windows & Siding Inc

Very pleased with the customer experience, the installation, and the product. The windows look great and appear to be great quality.

They replaced our front door, sidelights, & storm door. Great product, great value, great service. We are thrilled with the results.

We have had a relationship with Illinois Energy for about 5 years now with multiple rounds of installation as our budget allowed. They have now replaced all of our windows, the front door and gutters and every experience has been stellar. From the initial sales meeting to the measuring appointment through installation, every employee and crew has been friendly, responsive to questions, knowledgeable, efficient and detail oriented. We never felt pressured to add on services or go beyond what we could afford but knew we would get the same quality and service each time we were ready for another round. It is almost sad that we don't have any more for them to do! We will not forget the small personal touches or the above and beyond moments each of the team members and crew left behind. Thanks again for helping make our home improvement journey a good one!

We have hired Illinois Energy for all of our window projects, and we have always been pleased with the quality of the windows and the excellent customer service. They just finished the last of our window replacements. We are already seeing better energy efficiency in our home and the noise reduction is amazing! We live near a busy street next to a train station, and we hear next to nothing since having these windows installed. Illinois Energy is an excellent company to work with.

We most recently had a portion of our windows replaced on the back of our home along with our sliding glass patio door. From the time we sat down to meet with the personable sales manager to the incredibly respectful installation crew we could not have been happier. They arrived on time and left no mess for us to clean up. They knew what our needs were and were not pushy at all. The customer service department is very helpful and easy to talk to. Our windows and patio door are easy to operate and keep out the draft. We will definitely be using them again to replace more windows in our home.

Illinois energy was very professional, very considerate of my family and pets during the installation. The workmanship was impeccable. And yes, I would definitely hire them again.

During the pandemic, we replaced our family room windows and sliding door. I shopped around and had 4 other companies come out and give us estimates. Illinois Energy Windows gave us the best price and had the best warranty. 2 years later, we went back to them to finish our upstairs. We replaced 8 more windows and again, price was reasonable. The workers for both of the times were very nice and really cleaned up after them selves. They moved all our furniture and returned it when they finished. This company has been around for over 20 years….they aren’t going anywhere! They also have the best customer service….this is a family owned business so make sure if you are looking for windows, support Illinois Energy Windows & Siding.

I have had all of my windows replaced by Illinois Energy and I would highly recommend them. Everyone I have worked with has been great and very professional. The windows are really good quality.

Working with Illinois Energy was the best decision we could have made for replacing our patio door! From start to finish, they were professional, responsive and went above and beyond to make everything work for us. The free estimate visit was booked quickly and their knowledgeable and friendly salesman was honest and transparent about their products and pricing as well as competitors. The day of installation was a breeze as all the work was completed in the morning and a minor unexpected discovery led to no additional charges at all. The customer service was excellent as they followed up to make sure everything went smooth. The incredible and thorough warranty coverage included with everything is truly the best peace of mind you could ask for. The leaking issues with the previous door are a thing of the past and we know this door will last us for the long run and save us a ton on energy costs. I highly recommend Illinois Energy for anyone looking for windows or doors!

I had all of the windows in my home replaced by Illinois Energy. We used them for some exterior doors several years ago and had such a good experience that we remembered them and called them for the windows too. The work is very high quality, the installation crew was prompt and efficient and even accommodating to me while replacing the window in the room where I work from home. Overall a fantastic experience and would absolutely recommend

My house has settled over the years and it became increasingly difficult to throw the deadbolt on the garage door leading into my backyard. Also the 50+ year old single pane sidelights of my front and back doors caused cold spots every winter and I was using narrow shades all summer to block the hot sun. I found a sales flyer from Illinois Energy Windows & Siding Inc. on my door in late November and called for an appointment. The sales agent came to my home with sample binders. This greatly simplified the selection process by making it easier to envision how well each door or hardware choice would look in my rooms. It also is great for picking the best colors to complement the door areas since you make your color selection in available light of the actual space instead of the typical harsh florescent light in a retail store. I told him I wanted to increase my front door to a 40 inch model and my back door to a 36 inch of course with narrower sidelights. If my old garage door also had a sidelight, I would have gone with a 36 inch replacement to make it easier to roll out the lawnmower. Before the appointment, I spent several hours grabbing screenshots of the types of doors that I thought would look best in front & back. He reviewed the pictures on my tablet, asked a bunch of questions and we had a good discussion. This was no way near the canned, high pressure sales pitch I was anticipating. It probably took too long on my part, but there were so many choices to select from. He was patient, helpful and would offer good advice when I asked. As is now common, a few supply chain issues caused delays or resulted in me making some minor changes to hardware to move things along. But I was kept up to date with voicemail and text messages from them and never had to track someone down for an update. Since I wasn't in a hurry from the start, this wasn't a concern. The installation was painless for me and very efficient. The installers covered the areas with plastic to contain any mess and everything was absolutely spotless when they were finished. They did most of the pre-assembly work on my driveway and went out of their way to prevent debris from flying around the neighborhood. They removed an old door and completely cleaned up that mess before moving to the new installation phase. Here's another big plus. They used caution tape to secure their laydown / work area before unloading the new doors from their truck. I have a neighbor who likes to "help supervise" projects like this and I believe the barrier tape and "Work Zone" signs kept him at bay. I did not remember this from the sales meeting (there was a lot of talking) but the 3 storm doors were all made my Larson, a top notch storm door manufacturer. The installers matched my existing interior moulding / door trim so the new doors blend right in. The work was finished 6 days ago. I waited to write this in case something popped up, but it never has. I remain extremely pleased with the fit and the quality of the 3 exterior pre-hung doors I selected. And the installers were top notch professionals. I don't know how common a 20-year transferable warranty is these days, but it is a big plus in my book. While I am 100% certain I could have had three doors replaced for a lot less money, if it turns out that they continue working this well and looking this good for the next 20 years, it was well worth the money. And although it's too hard to prove, I will save a little on my future energy bills. No compensation was accepted for writing this review.

We bought our new front door from IL Energy. They were responsive and efficient to work with throughout the process. The work was done correctly the first time and they were respectful of our property. Everything was done with professionalism. I would recommend them.

The salesman, Paul Nicholson, was very professional, knowledgeable, and helpful with setting everything up and helping us pick out what was right for what we needed. The windows are the right price for the quality of product and professionalism we received. They came out again before Installation to double check measurements and know exactly what had to be done. We used Illinois energy twice, and both times the group of gentlemen that did the Installation definitely exceeded our expectations. They were quick, cleaned up after themselves, taught us how to use them, friendly, and communicated their time arrival and met they time window. I would absolutely recommend Illinois energy!

Great experience with the company. The crew was very professional and completed the work quickly. I am very pleased with the windows and door. I have already notice a difference in the noise coming in from outside. I can imagine it will also make a huge difference in my hearing and cooling bill.

After my parents, my brother, and my wife's parents all used IEW for windows and siding we figured it was our turn! Garrett came out when both my wife and I could be available and explained what we did and did not need. Never felt pressured or "tricked" into buying anything. We went with insulated siding as he said our issues were most likely siding related rather than windows and if we had to do only 1, he would do siding. ..... he was right! The insulated siding is amazing! Home is warmer and quieter! The basement escape windows are definitely worth the extra money. While they are a bit more expensive than others; they look nicer, insulate better, feel safer, and will likely last a LONG time by the look and feel of them. The installing team really busted their tails. Very meticulous and attentive to detail. There were only 2 or 3 very minor issues that needed correcting afterwards (fyi: there always are no matter what project it is so don't freak out when it happens!) Very responsive (you will NOT find a better warranty), IEW had one of their maintenance technicians out in less than a week who fixed everything on the spot! also, this guy is really amazing. While he was fixing the issues i noted, he asked if i had any other questions. I did - some were not even related - and he answered them anyway. Eventually we will need new windows - we will be using IEW for that too! Thanks for a great product and service. Our family thanks you!

My husband John and I used Illinois Energy for our new front door. Our salesman was professional, knowledgeable and thorough with answering all of our questions. Our door came earlier than we expected and we are blown away with its beauty and quality. This is a stand out product that has upgraded both the interior and exterior of our already beautiful home. The installation was seamless and done with expertise. You get what you pay for and more. I highly recommend.

Great selection of products, affordable and experienced. The customer service is top knotch. I will be returning for future projects.

Excellent company with great products and service. Have used them for multiple projects over the years and have always been very satisfied. Everyone is very professional and strive to make sure you are happy with their service. I would reccomend to anyone who is looking for windows, siding or doors.

Purchased new exterior back door with screen door. All aspects of service were excellent. Salesman was knowledgeable and very helpful. Office staff was professional. Installation team did a beautiful job and cleaned everything up when finished. I would highly recommend Illinois Energy.

We had a triple panel sliding door replaced by IEW. We are very pleased with the quality of the door. It looks & functions as promised. And, the installers did a wonderful job while keeping the surrounding area inside and outside our home neat and clean. We highly recommend IEW!

They did a great job and got the custom door and window done and installed even sooner than expected!

From our first interaction with IEWS we experienced a genuine, honest, concerned and professional relationship. Attention to detail was especially key through the whole process until final clean up. I would highly recommend this company if you are looking for an integral partner who you can trust to do a fantastic job!

They did a fantastic job. They were on time and did the installation of a new picture window for me. The guys were very nice, they did the installation in a timely manner under the time they had extimated. They cleaned up after themselves, took the old window with them and even washed the window inside and out!! I was very pleased with the absolutely wonderful job they did!!

Had a great overall experience with Illinois Energy, from the time we talked to the salesman to the install itself. Everyone was knowledgeable, professional, on-time and friendly. Also there prices are hard to beat. I would definitely recommend them and look forward to doing business with them in the future.

This company is wonderful to work with. Very professional and helpful with anything you need. The quality of the windows is excellent.
