Zen Windows Columbus, Columbus

Zen Windows replaces worn-out windows with fresh windows of all styles, be they double-hung, sliders, or cut into unusual shapes. The company custom makes patio doors as well as carries a range of Energy Star windows, which help preserve homes' internal temperature. The company refuses payment of any kind until work is finished and customers are happy—an attitude which has earned it recognition from Angie's List and The New York Times.
