Window Replacement for Fountain Valley Homes
Mostly 1960s and '70s single-family tracts make up much of Fountain Valley, and many still have original or first-generation windows. The marine layer keeps Fountain Valley mild most of the year, but afternoon sun on west- and south-facing walls still drives heat gain, so Low-E glass with a low solar heat gain rating keeps those rooms comfortable.
Homes near the I-405 often add laminated acoustic glass on the noisy side of the house.

Retrofit vs. full-frame replacement
Most Orange County homes built from the 1960s through the 1990s still have their original aluminum frames. In a retrofit installation we leave the existing frame in the wall, cut away the old sash and set a new window into the opening, sealing it inside and out. It avoids stucco and drywall repair and is the most affordable option. Full-frame replacement removes everything down to the studs — the right choice when the frame is rotted, the opening is being resized, or you want the slimmest possible sightlines.
