"I had a foundation issue that caused a window to shift out of its casing. Window World was happy enough to help me with just the one window that would need to be replaced. The sale, scheduling to the installation was done very quickly and everyone was all very polite and professional."

"Highly recommend this company for windows. Had all windows in the house replaced with good quality energy efficient windows at an unbeatable price. Install crew was fantastic, and customer service is best I have ever had, after getting some caulk on one of our new screens, they ordered a replacement for us without having to ask them to. We had a quote from another company for windows with same energy ratings and similar construction but they wanted 3x the money for the job. Don't look any further than NuSash for your replacement windows."

"The installers were great. The salesperson made promises that he did not keep and he missed a window. When the person came to measure he also didn’t catch that I was having all my windows done except one. The windows look great. The response when I notified the co that one window was missed was very fast but added to my cost."
