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.

We replaced all of our windows upstairs with Illinois Energy windows. The windows look fresh and the installation process was easy. They look great and are much better than our name brand Pella windows we previously had. We appreciated the great customer service and follow up.

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 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.

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.

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!!
