Retrofit vs. Full-Frame Window Replacement
Window replacement guidance for Southern California homeowners.
Last reviewed: September 2026. Verify codes, manufacturer specs, and rebates before acting.
Retrofit (insert) windows install into your existing frame—faster and less disruptive. Full-frame replacement removes the entire old frame down to the rough opening—best when frames are damaged or you're changing size or style.
Choose retrofit when your frames are square and solid. Choose full-frame when you need to address hidden damage or want a complete weathertight seal. We inspect and recommend the right approach during your free consultation.
