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.
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.
Meeting California's energy code
Replacement windows in California must meet Title 24 energy standards. For whole-house projects that generally means a U-factor of 0.30 or lower and a solar heat gain coefficient (SHGC) of 0.23 or lower in Orange County's climate zones. Every window we quote is a dual-pane, Low-E unit that meets the code, and we handle the paperwork and permits where your city requires them.

Frequently Asked Questions
How long does window replacement take?
Most homes with 10–20 windows are completed in one to two days. Custom sizes usually take 3–6 weeks to manufacture after the measure appointment.
Do I need a permit to replace windows in Orange County?
Many Orange County cities require a permit for window replacement, especially for full-frame work or changes to the opening size. We check your city's rules and pull permits where they're required.
Is retrofit or full-frame replacement better?
Retrofit is faster and less expensive and works well when the existing frame is sound. Full-frame is better when the frame is damaged, you're changing the opening, or you want maximum glass area.
