Illinois Energy Windows & Siding Inc

Illinois Energy (IE) has worked on pretty much our entire house and we have loved partnering with them. The sales rep, Paul, was always very respectful and honest. He never pushed any projects that we weren't interested in and was incredibly knowledgeable about all the products IE offered. While it may be unusual, I looked forward to doing projects with IE partially because I so enjoyed getting to know Paul and building a friendship with him that went beyond home improvement projects. We also looked forward to working with IE because of how efficiently they worked when at our house and the quality of the installation of the products. The products and the work installing them were very high quality and there is no way to beat their lifetime of the house warranty. With IE you get far more than you pay for in the quality of the products, the quality of the installation, and (most importantly) the quality of the people you will work with.

Our new windows from Illinois Energy look great. Everyone at the company was wonderful and easy to work with. Warranty is amazing. Install only took a day. Very pleased.

I highly recommend Illinois Energy, Windows and Siding if you need to replace windows, doors, gutters or siding for your home. We had new gutters replaced on our house in September, 2011. I am writing today, because we recently needed to extend a gutter on the second story of our home, and not only did Illinois Energy come out to do an excellent job, but IT WAS STILL COVERED UNDER WARRANTY! AFTER 13 YEARS! :) Illinois Energy is customer focused with outstanding customer service, quality materials, and a warranty which covers both parts and labor. I am so grateful that they installed my gutters (and keep them in working order!), and they are first on my list for any other external repairs we need for our home. I am completely impressed with their professionalism, and highly recommend Illinois Energy!

Great selection, service and knowledge. Installer did a beautiful job on the hottest day. Very professional and detailed oriented. Highly recommend.

They did a great job, this is the second time we've used them and we are just as happy as the first time. We'll be using them a third time when we're ready to finish the rest of the windows. Everyone we dealt with was top notch. The sales inspector, the installation guys. Even the people at the office were great

Just wanted to give a shoutout to Illinois Energy for the awesome job they did on my new windows, fascia and soffit! The sales rep, Garret, was super helpful and made the whole process easy to understand. This is my second time working with Garret and he has made the process painless both times. I have now installed just about everything Illinois Energy offers across my first two houses. The guys who did the installation were great - showed up on time, worked fast, and left everything clean. The fascia and soffit have really made my house pop. Replacing the old wooden features with wood grained aluminum was a great choice. And the windows! They look amazing and my house already feels way more comfortable. If you're thinking about getting new windows or siding, definitely check out Illinois Energy. I'm so happy I did!

Great experience from start to finish. Super helpful and very professional. End result turned out better than expected

Illinois Energy installed 3 exterior doors for us. They delivered a great quality product by a highly skilled installer who faced unique challenges with 2 of 3 doors. Illinois Energy was also the most affordable with the best warranty package compared to two of it's competitors. Lastly, customer focus to rectify inconvenient situations sets their standard high from a business ethics perspective which I cannot truly say if their larger competitors would deliver. Other than a delayed installation date and installer scheduling with a two day job taking 4 days during 3 different weeks, we were satisfied with their service and would definitely consider utilizing them again in the future.

If you’re looking for quality and professionalism, Illinois Energy is the way to go. The warranty is the best in the industry and they have an actual location in Lisle that been there a long time. The office staff is organized and on top of things. The installation crew really took the time to make the installation perfect. The sliding door I had installed feels solid but at the same time effortlessly glides open and closed. The lock mechanism operates easily and is secure. I’m looking forward to working with them on future projects. 100% recommend Illinois Energy for doors and windows!

We just bought more windows from Illinois Energy Window and Siding. They are flexible and very knowledgeable. The installers were courteous and clean.

The installers arrived on time. The old windows were removed. The new windows were installed in a timely manner. We were shown how to operated the special features (tilting for cleaning and locking). We love the look of our new windows.

Company was very professional and easy to work with. Windows are high quality and worth the money.

Their personnel were professional at all times. Everything was completed in a day. Site was left clean. I am so pleased. 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.

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 estimated 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.

Great company to do business with! Second home we had them replace windows. Installed 17 windows in 1 day! Great warranty, installers and customer service!

Our experience with Illinois Energy was great from start to finish! The rep from their company was very informative and answered all of our questions. The crew that installed our windows were just as great. They were efficient and cleaned up everything when they left. You wouldn't have know they were even here. I would highly recommend this company!

I recently had a patio door installed, and I couldn't be happier with the results! The entire process was smooth and hassle-free, from the initial consultation to the final installation. The team was incredibly professional and punctual, arriving exactly when they said they would and completing the job within the promised timeframe. The quality of the patio door is outstanding. It's both beautiful and functional, seamlessly blending with the existing decor of my home while providing excellent insulation and security. The materials used are top-notch, and you can tell that a lot of care and precision went into the craftsmanship. The installation crew was polite, respectful, and highly skilled. They took the time to explain the installation process to me and made sure I was comfortable with every step. They also left the area spotless, which I greatly appreciated. The new patio door has transformed my living space, letting in more natural light and providing a stunning view of my backyard. It has made a significant difference in the overall ambiance of my home. I wholeheartedly recommend this company for their exceptional service, quality products, and meticulous attention to detail. If you're considering having a patio door installed, look no further – you won't be disappointed!

Used IEWS to replace our patio sliding door. The new door was made and ready to install around 2 weeks upon signing the contract, which is a month earlier than estimated. The installation went smoothly and was finished in about half a day. The door is much improved from our previous door and noticeable difference in the quality. The glass and screen door slides effortlessly. The glass door doesn’t close all the way unless you push it hard. So far, it seems fine and we shall see how it holds up over the next few years with the seasonal changes. Overall, we are happy with the service with IEWS and will use this company when we are ready to replace our windows.

What a great experience. The designer, installer and follow up was flawless. I just walk by our door and admire it everyday since installation. What a gift I gave to our home by making this investment!

Our experience with Illinois Energy was great from start to finish! The rep from their company that came to our house, Derek, was very informative and answered all of our questions. The crew that installed our windows were just as great. They were efficient and cleaned up everything when they left. You wouldn't have know they were even here. I would highly recommend this company!

We've used Illinois Energy for the last 10 years! We replaced all our windows in 3 phases. They are always very professional from the estimate to the installation. No pressure, easy to work with and great communication!

Illinois Energy Windows & Siding did an outstanding job of replacing about half of my old windows a couple of years ago. I didn't hesitate having them come back to replace the remaining windows. The quality of materials and the professional installation was wonderful. I would highly recommend them to my family and friends.

When Paul arrived to give us an estimate on our porch door, he was very knowledgeable about the structures of the house as well as the products they had. He was able to provide us with some education on the variety of doors as well as well as the process they are made. The office team was very helpful and easy to communicate with to find the perfect time for our installation. The actual day of the install was seamless. The contractors did amazing work and were nice enough to explain to me the entire process of the installation as well as any strange findings our older house presented. The new door brings a new life to our porch and is making us want to spend more time on it than before.

The salesman, Jerret, was very patient, explained all our options, listened to what we wanted, and spent the time to craft products that fit our needs. Installers were great as well. Wonderful people that came, worked hard, and were very helpful. Overall, it was an excellent experience.
