Love my new windows
Love my new windows, so much sunlight comes in now unlike before. Very professional team that installed the windows, very clean and took care of cleaning up after themselves.
Top Notice
I've worked with IL Energy for two home projects now. New gutters and a sliding back door replacement. They were done quickly, very professional and cleaned everything up. I already have plans to start another project with them soon. Their office was very communicative about scheduling (rescheduling due to weather) and follow up to ensure I was happy with the work competed.
Love it!
We have a 9’ opening overlooking a golf course. We “inherited” Pella doors but the seals were broken and had cold air and even some frost come underneath the door last Winter. Illinois Energy Windows & Siding did our install in December, it’s now mid-February, and our house is well insulated with the new doors. We have a beautiful view and the sleekness of the new doors has enhanced the view. Friends and family have asked if we had the opening enlarged because of the effect. The staff, from salesman to office staff to installers were great to work with. We love our new sliding patio door!
Fantastic
We got a new sliding patio door. It looks amazing and I'm beyond happy with the final product of it. I had a great experience from start to finish. The kid at the door was who originally convinced me to give them a try. Then the man we met with who organized it all was knowledgeable and friendly (he was very good with chatty toddler) and the man who installed our door all by himself on a cold January day was effective and impressive. I'd highly recommend using them for whatever you may need. Great company and amazing product/work.
Repeat customer with a great experience both times
The truest measurement of customer satisfaction is repeat business. Our first project was in 2018 to replace an entryway and and few windows in the most dire need of replacing. We had always planed to have a second phase of the project to replace the rest of the windows, but didn't plan on that being almost 7 years later. Over that time I looked into specials being run by other companies but never felt like I was getting the full story. So when we decided that we didn't want to put this off replacing the remaining 9 windows any longer we reached out to the team at Illinois Energy Windows and Siding and I'm happy to say that they were just as good as I had remembered, if not better. The sales person was knowledgeable, we were kept up to date on the status of our windows and scheduling the install, and the installation crew was courteous, fast (but never seemed rushed), and thorough in their clean-up. We would not be happier with the process or the results of the project.
Superb service
We experienced a company that provided excellent service from the point of contact. Garrett in sales, Jill and Jessica in scheduling , John and Adam the installers were very efficient and professional. Illinois Energy provided an excellent product and we would definitely refer anyone that needed any of their services.
Best Customer Service &Quality Windows
Illinois Energy exceeded our expectations. Like most people, we weren't super excited about spending the time and money to get new windows, but every team member we spoke with (Mike, Nate, Jill to name a few!) Was so incredibly kind, patient with our numerous questions, responsive, and helpful. They made the entire process a breeze, and we are so grateful for their help when we had some tricky HOA approvals to navigate. 1000% recommend this company- we felt like they genuinely cared about helping us, and not just another sale.
Master bedroom windows
Great job! Have had two other companies replace windows, Illinois Energy wins! Clean, quick, no prep work required from me, hung the blinds back up and everything. And the windows are super clean, look great and really keep out the cold. Thank you!
Outstanding windows and doors.
We've had Illinois Energy Windows & Siding do our windows several years ago. Beautiful windows and noticed an immediate reduction in our heating and A/C electric bills when they went in. Our old builder grade windows were not cutting it! Recently, we had them replace our back sliding door. World of difference. No more cold draft near the door! And its opens/closes easily.
Excellent service and doors
Door replacement was very professional. New doors make our home more beautiful.
