Window Replacement for Rancho Santa Margarita Homes
A master-planned community built mostly from the late 1980s through the 2000s make up much of Rancho Santa Margarita, and many still have original or first-generation windows. Summer afternoons in Rancho Santa Margarita 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 241 Toll Road and Santa Margarita Parkway often add laminated acoustic glass on the noisy side of the house.
Many Rancho Santa Margarita neighborhoods have HOA or architectural review guidelines for frame colors, grid patterns and door styles — we provide product specs and drawings for your approval application.

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.
