Los Angeles Window & Door Replacement Contractor. the openings that change the room.

Replacing windows and doors in LA is rarely just a swap. It's a Title 24 conversation, often a structural-header conversation, and always a flashing-and-WRB conversation. We replace, retrofit, and build new openings across LA County with proper head flashing, sill pan, and integrated weather-resistive barrier laps.

What we resolve before drawings begin.

  • 01

    Title 24 U-factor + SHGC

    All LA replacements must meet Title 24 U-factor and SHGC targets. We specify NFRC-certified product and document for permit closeout.

  • 02

    Header and shear when enlarging openings

    Cutting an opening larger than existing triggers a structural header + lateral bracing recalc. We commission the engineer at feasibility.

  • 03

    Flashing + WRB integration

    Proper sill pan, head flashing, and WRB lap detail. This is how a window installation either lasts 30 years or starts leaking at year four.

    Like-for-like vinyl retrofit usually doesn't, but full-frame replacements, header changes, and any structural opening changes do. We pull permits when required.

    All replacement glazing in LA must meet Title 24 maximum U-factor and SHGC. We specify NFRC-labeled product and submit the certificate at permit closeout.
