AfterWindow Company in Corte Madera, CA
Corte Madera sits in a spot few other Marin County towns can claim: half the town’s homes perch on the hillsides west of US-101, and the other half spread across flatlands that were bay marsh until the 1950s. That split changes everything about window and door work here. Homes east of the freeway absorb daily salt air off San Francisco Bay, while hillside homes deal with afternoon wind and direct sun. We’re Westlight Windows & Doors, and we plan every Corte Madera job around those conditions from the first measurement to the final caulk line. Call us at (903) 354-7134 for a written price before any work begins.
Why Corte Madera Homes Are Different
The bay-fill neighborhoods east of US-101 were built on engineered fill over bay mud in the 1950s and 1960s. That’s the single most important fact about working on windows and doors in Corte Madera. The homes themselves, mostly ranch-style and California contemporary, are now sixty to seventy years old, and the original single-pane aluminum windows they were built with were never designed for daily salt-laden breezes. Aluminum frames oxidize, window seals fail, and wood sills delaminate faster here than in Kentfield or Larkspur just a few miles inland. The marine layer keeps humidity elevated year-round, which means condensation forms on single-pane glass through most of the year.
We also see a problem specific to the flatlands that hillside Corte Madera homes rarely experience: differential settlement. The soft bay mud beneath the eastern neighborhoods settles unevenly over decades, and that quietly racks door frames out of plumb. A pre-hung door replacement in a 1960s rancher off Tamal Vista Boulevard routinely needs more shimming and frame squaring than the same job in the hills west of town. Any contractor who treats a Corte Madera door like a door anywhere else will fight the opening all day and still leave gaps.
Our Main Corte Madera Services
Corte Madera homeowners call us most often about two things: windows that have finally failed against the salt air, and doors that no longer close square. Each service has its own Corte Madera page, linked below, where we go into pricing and process in detail.
Window Replacement in Corte Madera
Replacing windows in Corte Madera usually means pulling out original single-pane aluminum units and installing modern double-pane frames that can stand up to bayfront conditions. On the flats east of US-101, we recommend marine-grade fiberglass frames and coated stainless hardware as a baseline, not an upgrade, because standard aluminum will begin oxidizing within a few seasons. Our team measures every opening individually, because sixty-year-old homes have shifted and settled. Read our full breakdown at Window Replacement in Corte Madera.
Window Installation in Corte Madera
New-construction window installation in Corte Madera comes with its own set of constraints. Hillside homes west of US-101 often have stucco exteriors and limited access, which changes how we flash and seal each rough opening. Flatland homes near the bay demand extra attention to moisture management, since the prevailing afternoon wind drives rain and salt spray against east-facing walls. We install products from eight manufacturer lines, including impact-rated PGT and CGI for homes that face the water directly. See Window Installation in Corte Madera for the full scope.
Door Installation in Corte Madera
Door installation on a 1960s Corte Madera rancher is rarely a simple swap. The settlement we described above means pre-hung doors need serious attention to plumb and level, and we square every rough opening before the new frame goes in. Salt air also pits cheap steel hinges and handles quickly, so we steer flatland homeowners toward coated or stainless hardware. Entry doors from Therma-Tru are a common choice here because they hold up to moisture without warping. Details are on our Door Installation in Corte Madera page.

Whatever the number, you receive a written price before any work starts, and that price does not change at the door. No revised invoices, no surprise line items.
