Very Happy
We are both salespeople so we don't waste other salespeople's time. We had three companies out. IEWS had the most honest presentation of the group and we liked the product offering and timeline. The delivery was ahead of the estimated date provided which was a pleasant surprise. And the two installers (father and son) were literally fantastic. And I run a company that provides install services so that actually is saying a lot. Recommend IEWS whole heartedly.
Value added product line
I highly recommend using this company. Their windows are crafted with the best materials to generate energy savings in utility bills. The look of the windows are excellent as well, the value is there.
Love our Windows
We replaced all our windows using Illinois Energy. Turn around was quick and the quality of the windows is great. We’ve already noticed a difference with no more drafts or leaks. There was a small issue at installation where 2 of our screens didn’t fit quiet right. The company repaired and replaced them quickly. Overall we are satisfied and happy with our purchase.
Double door basement windows
Outstanding job done by Patrick and his Dad work as a team and work ethic was very professional
Love this company
This is the 4th project Illinois Energy has completed for us. We are return customers because of their honest dealing, fair prices, and quality product. They have been more than happy to work with us as we complete a set of windows at a time. Their windows are well-insulated against the cold and noise. Our house backs up to a busy street, but you’d never know it with our new windows.
Strom Door and exterior door replacement
They provided an excellent door at a reasonable price. I was very happy with the installation and the service. I highly recommend using Illinois Energy windows & siding.
Excellent quality and service
I had four windows replaced. They were installed within 3 hours. They work and look great! In addition, they are lifetime warranty. I would do business with this company again.
4 Windows Replaced
We had 4 windows replaced from being rotted out. They replace the windows and the material around them to ensure the best quality. The also completely tore out one window and replaced it with a different shape. All the work looks great and it was all done in one day, including clean up. I'd use their service again.
Kitchen window
The guys were professional and explained everything I needed as far as the operation of my window and patio door.. Also they cleaned up after themselves. I would recommend this company to anyone that needs windows or doors..
