Window and door replacement, all brands, done right.

Window performance depends as much on installation as on the product. Flashing, the connection to the weather barrier and the stucco or siding repair around the opening decide whether a window stays dry.

The contractor we connect you with installs all brands of windows and exterior doors, can help you compare product lines on energy performance, frame material, style and budget, and installs them with the flashing details each manufacturer specifies.

Retrofit or new-construction windows?

Retrofit (insert or flush-fin) windows fit into the existing frame or over the existing opening without removing exterior stucco, which keeps cost down. New-construction (nail-fin) windows replace the whole unit down to the framing and are flashed into the wall, which is the most watertight approach but requires stucco or siding repair. Our window replacement guide explains when each makes sense.

Whole-house window replacement

Replacing every window at once is often paired with a remodel, when walls are already open and new-construction windows can be flashed in properly. In older homes, matching the original window style can matter as much as the installation method.

Doors

Entry doors, French doors and sliding patio doors, including reframing when an opening is widened or a window becomes a door: header, threshold, flashing and finish trim.

Energy code

Replacement windows in California must meet the Title 24 energy code. In Ventura County and the South Coast that means a maximum U-factor of 0.30 and SHGC of 0.23 under the 2025 code, with a small-replacement exception. See the guide for details.
