The sales person was a nice young man who was doing his best to sell the company product. Once the installation commenced, i was very pleased with 3 of the 4 windows that was installed.

Sales was very helpful in walking us through the process and options. The installers were excellent. They worked fast, clean, and efficiently. They answered all questions we had. They were very respectful. We are very happy with the work done and plan to eventually have the remainders of our windows replaced by IL Energy.

He worked carefully all morning to make sure our door and sidelights fit well and are
