AfterWindow Company in Topanga, CA
Topanga is not an easy place to do window and door work. Canyon slopes, high-wind ridgelines, wildfire exposure, and homes that range from 1940s cabins to architect-built moderns all show up on the same crew schedule. We run every Topanga job with that reality in mind: the price goes on paper before we start, and the work is covered in writing for a full year. If you’re pricing window replacement or a new patio door in the canyon, call (817) 686-2228 and we’ll walk you through what the job will actually cost.
Why Topanga Homes Are Different
Topanga sits in the Santa Monica Mountains, and the terrain dictates almost every decision on a window or door project. Many homes here are built on slopes or tucked into canyon walls, which means access can be tight, staging space is limited, and window openings rarely sit square after decades of soil movement. We expect that. Measurements get rechecked on site, not copied from a previous quote.
Wildfire exposure is the other constant. Topanga is in a California High Fire Hazard Severity Zone, and window selection has to respect that. Tempered glass, fire-rated frames, and ember-resistant venting are not optional upgrades in the canyon; they’re often what the job requires. Homes near Old Topanga Canyon Road and Entrado Drive see real wind, and a patio door with a flimsy track will fail there faster than in the flats.
Housing stock varies wildly. A 1950s redwood cabin above Fernwood has different framing, flashing, and sill conditions than a newer build off Saddle Peak Road. There’s no single “Topanga standard” window, and any contractor who prices the work without knowing the difference is guessing. We don’t guess.
Our Main Topanga Services
Most Topanga homeowners call us for one of three jobs: replacing failing windows, installing windows in new construction or additions, or putting in a patio door that actually seals and slides. Each has its own page here, because the scope and the pricing are different enough to deserve separate treatment.
Window Replacement in Topanga
Old aluminum sliders and single-pane wood windows are common throughout the canyon, and by the time a homeowner calls, the telltale signs are already there: drafts, stuck sashes, fogged glass, or a sill that has started to rot from the inside out. Replacement jobs in Topanga often involve reframing around the original opening, because decades of settlement have pulled the old frame out of square. We spec the right glass for the elevation and exposure, and the price is fixed before any tear-out begins. Window Replacement in Topanga walks through the full scope and what to expect.
Window Installation in Topanga
New builds, ADUs, and additions up the canyon roads present a different set of problems. The opening is new, but the flashing details still have to hold up against wind-driven rain and ember exposure. We install PGT, CGI, and CWS frames regularly in Topanga, and on every new-construction job the rough opening gets checked before the window goes in. That step alone catches most of the failures we see when we’re called out to fix someone else’s install. Window Installation in Topanga covers the process, the brands we recommend, and the written guarantee.
Patio Door Installation in Topanga
A patio door in Topanga has to do two things perfectly: move easily and seal completely. Sloped lots mean water wants to run toward the house, and a door with a poor threshold or missing flashing detail becomes a leak within the first wet season. We install sliding and French-style patio doors with the sill work and weatherstripping done to hold up against the canyon’s wind patterns. Patio Door Installation in Topanga details what a typical Topanga door replacement involves and what it costs.

No. The price goes on paper before any work begins, and it doesn’t move at the door. If we find hidden rot or framing issues during the job, we stop, show you what’s there, and give you a written change order before proceeding. You approve it, or the job pauses at the original scope.
