Why Barrett & Sons Construction Is San Anselmo’s Preferred Windows & Doors Company
San Anselmo isn’t a place where you want a stranger walking through your front door. It’s a town where people know their neighbors, where the hardware store clerk asks about your kitchen project, and where a contractor’s reputation follows him from one block to the next. Barrett & Sons Construction has been doing Windows & Doors work in this part of Marin County long enough that our name comes up at the counter at the lumber yard and the post office. Customers in the 94960 and 94979 zip codes keep our number saved in their phones because when a window leaks during a creek-side storm or a door jamb swells shut in the winter, they want someone who already knows their house.
Every price you get from us is a written line-item quote. Every change after that is a written change order before work moves forward. The 90-Day Done Right Promise is written on every contract: if something isn’t done right, call Tom, and he comes back. We pull permits on every eligible job and we wait for the inspector to sign off. The inspector works for you, not for us, and that’s exactly why we treat him like the most important person on the job site. Our crews are Tom’s sons and the people they’ve trained personally. Not subcontractors, not a rotating cast. You’ll see the same faces from the first estimate to the final cleanup.
Read how we work across San Anselmo and you’ll find the same pattern: honest numbers up front, no surprises at the end.
Our Windows & Doors Services in San Anselmo
Window Installation
New construction or replacement, we handle both. Many San Anselmo homes near the creek sit in FEMA-designated Special Flood Hazard Areas, which means window placement and flashing details sometimes need flood-proofing compliance that a contractor from Novato or San Rafael might not catch until inspection. We know the Town of San Anselmo’s Flood Damage Prevention Ordinance, and we factor it into the quote from day one.
Door Installation
Exterior doors in this town take a beating. The valley funnels winter storm runoff right down Sir Francis Drake Boulevard, and north-facing entries on the hillside neighborhoods above Red Hill get wind-driven rain that other parts of Marin never see. We install doors with proper sill pans, drip caps, and flashing so the next storm doesn’t find a way inside. Interior door installation is cleaner and faster, but the same level of care applies.
Window Replacement
Most window replacements in San Anselmo involve older Craftsman bungalows and early California Ranch homes from the 1920s through the 1950s. Those original wood windows have usually been painted shut for decades, and the sashes have rotted at the bottom corners. We measure every opening individually, because after 70 or 80 years of settling, no two openings in these older houses are exactly the same size. We also handle whole-home replacement when you’re ready to move away from single-pane glass toward dual-pane efficiency.
Impact Windows & Doors
The upper hillside neighborhoods in San Anselmo are classified as High or Very High Fire Hazard Severity Zones under CAL FIRE’s WUI maps. That changes the window and door conversation. Ember-resistant assemblies, tighter glazing, and exterior-rated materials aren’t optional upgrades up there; they’re part of making a home defensible. Impact windows and doors also help with noise from the Boulevard and with the damp, cool air that settles into the valley floor most evenings.

Trusted Brands We Service in San Anselmo
We install Simonton and Ply Gem window lines regularly, and we can order PGT impact-rated products for hillside and fire-zone homes that need them. When a San Anselmo customer calls about a specific brand or a warranty question, we’ll give you a straight answer about what holds up in this climate and what doesn’t. We order directly from the manufacturers, not through a middleman, so replacements for damaged glass or failed seals arrive faster. That matters when your living room window faces the afternoon sun across the valley.
Common Windows & Doors Problems We See in San Anselmo Homes
- Water intrusion on creek-side lots. Homes within FEMA-designated AE flood zones near San Anselmo Creek often have window and door rough openings that were never flashed properly for consistent moisture. Once the sill plates start to rot, the repair scope jumps from a simple swap to framing work.
- Swollen wood doors during winter storms. The narrow valley holds more moisture than coastal towns like Mill Valley or Tiburon, so exterior wood doors swell and stick. Composite and fiberglass doors with proper sealing consistently outperform raw wood here.
- Failed double-pane seals from temperature swings. Summer days in San Anselmo can hit the high 80s while night temperatures drop into the 50s. That cycle stresses older dual-pane units, especially south-facing windows on the hillside, and fogged glass is one of the most common service calls we run in 94960.
- Windows painted shut in Craftsman bungalows. Many of these homes still have original wood sashes that someone painted over decades ago. We free them up where we can, but honestly, replacement is usually cheaper and smarter than trying to salvage a 90-year-old sash with failing glazing.

FAQs - Windows & Doors in San Anselmo
For standard estimates and installations, we’re usually at your door within 2 to 5 business days. Emergency situations like a broken entry door or a shattered window get prioritized, and we’ll tell you honestly when we can be there. Call (877) 610-1318 and Tom or one of his sons will pick up.
All of them. We work throughout the 94960 and 94979 zip codes, including the hillside neighborhoods above Red Hill and Sleepy Hollow, the flats near San Anselmo Creek, and the Sir Francis Drake Boulevard corridor. Flood zone, fire zone, or neither, we’ve done work there.
Yes, and this is where choosing a local contractor matters. The Town of San Anselmo’s Flood Damage Prevention Ordinance adds requirements that most out-of-town contractors don’t account for until the inspector flags it. We run the math on flood-proofing compliance before the first nail comes out, so the quote you get is the real cost. Call (877) 610-1318 and we’ll walk you through it.
Several reasons. The housing stock is older, so measurements are more custom and installation takes longer. Hillside lots above the valley floor add access time and sometimes engineering review. And the fire-zone and flood-zone requirements that exist in San Anselmo simply don’t apply in every neighboring town. A window job in San Rafael won’t always carry the same compliance scope. We’ll show you the line items so you can see exactly where the money goes.
Every job is backed by our written 90-Day Done Right Promise: if something isn’t right, one call brings Tom back. Beyond that, the manufacturers’ warranties on Simonton, Ply Gem, and PGT products apply, and we’ll help you file them if needed. Estimates are free, and we’ll put it all on a written quote before you sign anything.
