Terry looks for window manufacturers that are financially sound, have a great reputation, and come strongly recommended or personally referred. He also looks for longevity as a company, their ability to carry top leading brands in the nation, and offer exclusive warranties, plus more.

The windows that we sell are Energy Star rated and we've been an Energy Star Partner for many years. Here at Terry's, we've saved our customers up to 40% on their energy bills year round.
