We had Custom Windows replace all of the windows in the brick home we were remodeling. We were living out of state at the time and all of the arrangements were made by phone and e-mail. When we arrived at our new home months later we were so pleased with the windows, they were exactly the windows we wanted. They surpassed our expectations. The staff worked with us in a friendly and informative manner throughout the entire long-distance process.

The Custom Windows team did a first class job from measuring, explaining the options, giving us samples to decide with, and most importantly, references from other satisfied customers. The installation crew were as perfect as one could ask for in terms of a flawless installation, cleanup and leaving the house in as new condition.

Custom Windows was the only window company that could replace ALL our windows. Don’t be mislead by the other window suppliers as they cannot replace all the windows with exactly the same product or decline to bid on all the window replacements.
