Very satisfied with their job
They did an excellent job! The communication throughout the process was very good and clear and the workers were respectful, clean and efficient.
Our second project with IEWS
Excellent craftsmanship and beautiful product. Professional employees and installers.
Quality Windows
Excellent services from the start of the process, until the end. Punctual, Efficient, Excellent Communication, and installation was quick. The purchase price fit the window quality.
Patio Door
I'm a second time customer. This time I ordered a sliding patio door. I was informed from the time the order was placed to installation would be 6 weeks. I received a call within 6 weeks that the door has arrived and scheduled a date for installation. The day of installation the installers arrived and removed the old door and installed the new one. The installers were organized, neat and left the house clean. I would recommend Illinois Energy Windows & Siding.
sliding door replacement
I was very pleased with the replacement of my patio door. Extremely professional...
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.
