Window Company in San Anselmo, CA
Meridian Windows & Doors is the window company San Anselmo homeowners call when the job has to fit a house built in 1928, not a spec sheet. Window replacement and door installation in San Anselmo are different because the homes are different: single-family bungalows and Mediterranean revivals from the 1920s through 1940s, original wood sashes, settled door frames, and strict historic preservation guidelines in many neighborhoods. We work within those constraints. The price goes on paper before any work starts, every job is covered by our written 365-Day Done Right Promise, and someone answers the phone when you call (831) 273-7126.
Why San Anselmo Homes Are Different
San Anselmo sits in the rain shadow of Mount Tamalpais, which means more direct sun and less cooling fog than Mill Valley or Larkspur. That UV load does real work on windows: wood frames dry out and crack, glazing putty fails, and dual-pane seals break years earlier than they would in a coastal microclimate. A window that looks fine in January can show condensation between the panes by August.
The housing stock compounds the issue. Most San Anselmo homes are single-family builds from the 1920s to 1940s, heavy on Craftsman bungalows and Spanish Colonial Revivals. The original windows are wood sash, often double-hung, with true divided lites and wavy glass in the older Seminary neighborhood homes. Replacing them isn’t a pull-and-drop job. It means custom sizing, matching trim profiles, and sometimes working with the town’s historic preservation guidelines, which protect original windows and doors in many older districts. Newer hillside homes from the 1960s and 70s have their own pattern: aluminum sliders that bind in settled frames. In San Anselmo, we rarely install the same window twice in a week; every job gets spec’d to the house.
Our Main San Anselmo Services
San Anselmo homeowners most often call us for two things: replacing windows that have failed in the sun, and installing patio doors where the old slider has seized or leaked. Below is how each service works here, with a link to the full page.
Window Replacement in San Anselmo
Replacing windows in San Anselmo usually means pulling wood sashes from openings that have drifted out of square over 80 or 90 years. We measure every opening individually, shim and extend jambs where the framing has settled, and spec glass that handles the area’s UV exposure – low-E coatings are standard here, not an upsell. Historic homes in the Seminary neighborhood and elsewhere often require custom matching to preserve the original look while meeting current energy code. Window Replacement in San Anselmo covers the full process, including what changes when the town’s historic guidelines apply.
Window Installation in San Anselmo
New window installation in San Anselmo often involves homes that have never had modern units: no flashing, minimal insulation, and openings sized for long-gone custom millwork. We install to the existing opening with proper waterproofing and insulation, and we check for the dry-rot that Marin County’s wet winters leave in old sills and trim. Whether it’s a single replacement or new windows for an addition, the install gets the same written price and the same 365-Day Done Right Promise. Window Installation in San Anselmo details what a full install day looks like.
Patio Door Installation in San Anselmo
San Anselmo backyards step out onto hills, so patio doors here carry more sun and wind than they do in flatter towns. The common failure is a 1970s aluminum slider that has warped, lost its rollers, or let water into the door frame. We replace them with properly flashed, sealed units and check the threshold and subfloor for rot before the new door goes in. Frames that have settled often need jamb extensions, which we handle on every install. Patio Door Installation in San Anselmo covers sliding, French, and hinged patio doors.

The price you are quoted is the price on the written estimate. It does not move at the door, and if the job fails within 365 days, we come back at no charge.

FAQs About Window Company in San Anselmo
Most like-for-like window replacements in San Anselmo do not require a permit, but any change to the size of an opening usually does. Homes in designated historic districts may trigger additional review. We handle the permit paperwork when a job requires it and build the permit fee into the written estimate before work starts.
A standard single window replacement is usually a one-day job. A full house of wood windows with custom sizing may take three to five working days, depending on how many openings need jamb extensions or sill repair. We’ll give you a written schedule with the estimate. Call (831) 273-7126 to get on the calendar.
Yes, and that’s most of what we do in the older neighborhoods. We can match trim profiles, muntin patterns, and glass character, including the wavy look of original glass in the Seminary neighborhood. Low-E coatings are applied in a way that doesn’t change the historic appearance. Call (831) 273-7126 for a free estimate.
