Windows & Doors in Orange Homes
Typical homes in Orange: one of California's largest historic districts plus post-war and hillside neighborhoods.
Old Towne Orange is one of the largest historic districts in California, and window changes there follow the city's historic design standards — usually wood or wood-clad windows that match the originals. East Orange and Orange Park Acres have larger homes where big view windows and patio doors are common.
Summer afternoons in Orange regularly reach the 90s, so a Low-E glass package with a low solar heat gain coefficient (SHGC) makes the biggest difference in comfort and air-conditioning costs.
Homes near the 55, the 57 and the 22 often add laminated acoustic glass on the noisy side of the house.

“Replacing the windows made a bigger difference than I expected! The new ones have given the house a much more updated look, and I really like how the rooms feel with the brighter glass and fresh frames. The team was respectful and easy to work with throughout the window installation.”
