Window Replacement for Lake Forest Homes
A mix of 1970s El Toro-era tracts and newer 1990s–2010s communities make up much of Lake Forest, and many still have original or first-generation windows. Summer afternoons in Lake Forest 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 I-5, the 241 Toll Road and El Toro Road often add laminated acoustic glass on the noisy side of the house.
Many Lake Forest 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.

Signs it's time to replace your windows
Fogging between the panes (a failed seal), sashes that stick or won't lock, single-pane glass, drafts and dust around the frame, condensation on the inside of the glass, and rooms that overheat in the afternoon sun are the most common reasons homeowners call us. In coastal areas, pitted and corroded aluminum frames are another sign.
