Illinois Energy Windows & Siding, Inc.

They did a great job with everything. We got a window replaced and also a door moved and new windows installed.
They do more than just replace windows They will do the cut outs, siding, some electrical, drywall, trim. Pretty much everything you need.
There was a minor issue with the door they put in not beening adjusted properly and light was seeping in but they were quick to fix it.
There customer service has been very responsive. To anything I have had trouble with.
Definitely a huge recommendation from me.

Our new front door and screen door are beautiful. The gentleman that installed it did a wonderful job.

This company is great! Everyone that you speak to along the way is extremely helpful and knowledgeable. We are in love with our new window and will definitely use this company again in the future.

Great service, value and timeliness for new windows was quicker than quoted. Install was quick and not disruptive.
No pushy sales pitch and good breakdown of the process.

Our experience with IEWS was great! Everyone we've talked to has been professional and friendly. We spent a lot of time with their sales rep. as he went over the product, install expectations, financing, and warranty. There great communication with us throughout the process, from the initial sales meeting to customer service after the install. Our doors look awesome. And the install was quicker than we planned.fantastic, the install was very quick, Plus having a great warranty that is transferable is huge. We have more projects in the future, so we'll definitely be returning customers in the future.

We had our sliding patio door replaced by Illinois Energy. The customer service and installers were very professional and easy to communicate with. The install was in a reasonable amount of time, affordable, and of high quality.

We had a great experience working with Illinois Energy. The sales consultant spent the morning with us discussing the most cost and energy efficient windows for each room of our home. There was no pressure to upgrade or spend on additional features. We were shown a portfolio of nearby homes and competitive prices to help us make an informed decision. The office was in frequent contact with us prior to installation to ensure it went smoothly. Installation was completed in one day, and the installers were professional and courteous. The windows have been a great improvement to the look of our home, along with providing much better insulation and outside noise reduction. We would certainly recommend Illinois Energy to anyone else looking to replace their windows!

It was a very easy and and efficient process from start to finish. The estimate was pain free and we did not feel pressured at all. High quality windows and the lifetime warranty sealed the deal for us. The windows were made and our installation date was earlier than we expected. The installation process went well and we are very pleased with the results. Every employee we dealt with was helpful and easy to talk to. They made the entire process worthwhile. I would definitely recommend Illinois Energy to anyone needing windows and we will use them again in the future.

They were great and explain to me about the windows. It was very easy to open it to clean it while inside the house, better than climbing the ladder to second floor.

We’re so happy with our new door! It’s beautiful and definitely upgrades the look and feel of our home! The installation was excellent and the installers great to work with. We recommend this company and their work.

They replaced our front door, sidelights, and storm door. Great product, value, & service.

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!

This is an amazing company. Everything was explained throughout about fiancé, installation, and when will window arrive. The installers were very good and professional. I recommend for anyone who needs windows to check out this amazing company! Thank you for installing our window!

Thank you Illinois energy!!

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.

Illinois energy was very professional very easy to work with.

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
