Illinois Energy Windows & Siding, Inc.

We used this company over 20 years ago to replace windows in a previous house. When we needed a new front door package for the current house we chose them again. Products are outstanding quality, fairly priced given the quality and all processes are completed from order to install with upfront honest communication. The installers are wonderful, knowledgeable and very courteous.

Timely and very professional installation. I would highly recommend them to family, friends and neighbors. Great service!

Illinois Energy Windows did a great job from the initial sales process to installation. Their customer service was outstanding throughout the entire process.

Totally professional and helpful. Completed the project a full month ahead of promised date. A bit pricey but I smile every time I look at my new patio door and windows.

My experience with Illinois Energy and Windows could not have been more positive. I contacted them for a new front door and sidelight window in June. My initial meeting to full installation took about 2 months - exactly as promised. On the day of install (a Saturday, so I didn't have to take a day off of work) Rob and Paul arrived on time, worked steadily and competently to remove my storm door and the existing front door/sidelight window. They were constantly cleaning up as they went and worked seamlessly to install my new door unit and reinstallation of my storm door. Rob was amazing! His care and concern to make sure everything was perfect made me feel like he would have paid the same attention to detail if it was his own house. They even cleaned off the spider webs from my front porch so the door would look fabulous!! I love my new door and appreciate the financing options that were offered to me. You can't go wrong if you choose this company.

These guys were amazing! Got 14 windows done in two days, cleaned up very well after themselves, and the job was done so neatly thereâ s barely any touch ups for me to do. Very impressed, worth the price!!

Company offers a lot of choices of products and provides regular updates inb service and appointments. The best part was the great installation which makes even the best products perform poorly if not done right

They were the best! We got quotes from several other window services, and we knew upfront, we only had one or two windows that needed to be definitely replaced, and Illinois energy window replacement gave us a fair and honest appraisal., Other companies either try to sell us "whole house packages" or one company wouldn't even come out and look because I told them upfront we could not afford more than 1 - 2 windows. From day one Illinois energy was fair, honest, and completed all the work in the timeframe they promised. From the salesperson (thanks Derek) to the installers everyone was extremely professional and kind!. When I need the rest of my windows to replace I will call them, and I recommend this service to anyone who is looking!

We had 5 windows and a sliding glass door installed and we couldn't be happier! I keep saying "we have the Cadillac of windows" and they defiantly are with their quality. The windows frame my backyard perfectly! They were fairly large so we were nervous but they are stunning and you can feel zero heat transfer inside! They are trimmed out beautifully too! They'll be so easy to clean with the folding-in function and the child lock is very helpful with my 7 month old who is messing with everything. The sliding glass door I cannot get enough of; CROWNING GLORY! I can move the door with my pinky with ease. It has a kick lock which is too strong for my son to activate but easy for me. Before I had a wood kick plate outside which was rotting away but now we have a beautifully cased door with a vinyl or waterproof material that will last the lifetime of the doors. The installation process went so smoothly. Team of 3 men and they rocked out those windows like pros! They even took their shoes off EVERY SINGLE TIME they can in and out of the house. They laid down rugs to protect my floor and cleaned the windows and back area up when they were done. You couldn't even tell we have anyone working in our front lawn; everything was cleaned up so well. They even reinstalled my blind hardware before leaving which saved my husband a ton of time! They were polite and very good about wearing masks and keeping social distance. We couldn't have had a better team and I hope we have them again when we finish the other house windows! Payment options were great too; the price for windows was more expensive then competitors but I can DEFIANTLY tell the difference in quality of product and customer service. Their finance option was even cheaper than my Credit Union! The warranty is also better with IL Energy than the main brands we've seen on TV. The windows are covered 100% EVEN WHEN WE MOVE OUT the warranty is transferable to the new owner! #Lifetime of the house.. who else does that; NO ONE! Window parts & pieces, installation, labor, seal warranty, unlimited glass replacement all 100% covered! I would recommend IL Energy to a friend, neighbor, colleague and family because everything from start to finish was exceptional!

IL Energy installed our new patio door in under 4 hours! I can't imagine having to do this project myself, would have taken 4 weeks! The sales team was great to work with, amazing communication. I was very impressed with the install team. They quickly identified an issue with the install and were able to adapt onsite to address the issue. I would highly recommend using IL Energy for your next project!
