Great Craftsmanship and An Honest Company

Claire T.

We had an outstanding experience ordering our front and back entrance doors from Illinois Energy Windows & Siding. Before contacting them we had gotten a quote from a competitor and definitely had sticker shock, after that we scheduled a meeting with Illinois Energy & Electric. They were able to meet with us quickly and the rep we met with, Paul, was on time, friendly, helpful, and gave his honest opinion. The doors came within the estimates time frame and installation was scheduled shortly after. Our installer, Jerry, was on time, very courteous, and did a fantastic job with both taking out the old as well as installing the new. I also appreciated that they also do their own installations and don't outsource them. Overall we have been more than happy with our experience. The doors look great!

Did a great job

Ian R.

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.

Great Experience with a great company

Sara S.

We had such a great experience with IEWS. Our salesman was extremely helpful and knowledgeable. He recommended an awesome window and we could not be more happy. He let us know the exact timeline of things and assured us that we would be informed along the way, which we were. The installation took much less time than we thought it would and we are extremely satisfied with our brand new window and this company!

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.

Great experience with IEWS

Kelsey K.

We had a great experience with IEWS. Everyone we've talked to has been professional, friendly, and knowledge. We spent a lot of time with their sales rep. as he went over the product, install expectations, financing, and warranty. They communicated with us throughout the process, from the initial sales meeting to customer service after the install. The windows look fantastic, the install was very quick, and I know we have a great product that will last us years. Plus having a great warranty that is transferable is huge. We have more windows that will eventually need replacing, so we'll definitely be returning customers in the future.

Love our new windows

Evan F.

From the initial estimate, to the scheduling, installation, and follow-up, our entire experience was top notch. Joe came out for the initial meeting and estimate for five new windows and was on time, professional, knowledgeable, and in no way pushy. After deciding to proceed with Illinois Energy and Windows, a follow-up technician came by to double-check measurements. Our windows were manufactured and ready for installation several weeks early and Samantha made scheduling our installation super easy. Max and his crew (3 total) arrived right on time on install day and quickly got to work with laying down protective plastic and tape to keep dust to a minimum. We were told they should be able to complete the job in one day, but might need a second day depending on how the install went. The crew worked efficiently, but in a very thorough manner and ended by around 3pm. The team was diligent in cleaning up all of the debris and dust and made sure we were happy with the installation and had all of our questions answered before leaving. Beyond being very happy with the final installed product, I am most impressed by the organized and professional communication we experienced from start to finish. Despite interacting with numerous points of contact, it was clear that all were on the same page and up to speed on the project history and status. I would, without hesitation, go back to Illinois Energy and Windows for additional window replacements. Great job all around!
