Excellent 4.5 stars; it would be 5 stars but the increased cost of windows generally cost a half-star (even so, their quote was less than all others). These guys were prompt, professional, responsive, friendly, informative and helpful. So far quality of the windows is excellent. They delivered exactly what they promised. Complaints whatsoever; if you must get your windows replaced, these are the guys to call.
GREAT SERVICE!!
We had Illinois Energy replace our windows and doors. We are very happy with the installation process and final product. The staff was very helpful and knowledgeable. Stream lined installation. Would highly recommend!!! Thank you Illinois Energy!!!
Thanks Illinois Energy!
We first had Illinois Energy replace 4 windows on the second story of our home facing the street 16 years ago. We chose Illinois Energy at that time because of the quality of the windows, the value for the price, and the lifetime guarantee. Now 16 years later, we have not had even one single problem with any of those windows. So when we needed additional windows replaced, Illinois Energy was an easy choice for us. The new windows were just installed this week and we were again very pleased with the quality and value of these windows, and the professionalism of the installation team. We have and will continue to recommend Illinois Energy to our friends and family.

The technician arrived on time and began removing the old door and framing. The replacement was installed professionally and without flaw. I would highly recommend your service to all my friends.
A Transformed House & Garage
A Transformed House & Garage Exterior by Lloyd & Susan M Before we hired Illinois Energy to replace the siding and door & window trim on our house and garage we had always hired individuals or companies to complete work projects for us who were recommended by someone we knew. Such was not the case with Illinois Energy since we learned about this company via an advertisement, but we are very thankful we chose them. They transformed our house & garage from white 8” siding with shutters to an amazing-looking 6” blue siding with expertly crafted and installed white trim. We appreciated the professionalism, prompt communications and helpfulness exhibited by all the personnel we dealt with from sales, administration and installation. Ruben & Raul’s work crew, which included five other men, was absolutely great. They let us know their plans & schedules, performed their jobs well, sought our input for how we desired things to look along the process and made sure we were satisfied with ALL the work as it was being completed. We have commented to each other that it’s like we have a completely new place t
