AfterFast, Reliable Windows & Doors Across Sausalito
Window and door replacement in Sausalito is a different job than anywhere else in Marin. The salt-laden fog off the Golden Gate eats standard aluminum frames within five to seven years, which means the materials we specify here are not the materials we’d use in Mill Valley or Tiburon. If you’re pricing new windows or a sliding patio door, call Barrett & Sons Construction at (877) 610-1318 and we’ll walk you through what actually holds up on a hillside above Bridgeway or a floating home off Gate 5 Road.
Tom Barrett founded this company in 1998, and our crews have worked Sausalito long enough to know that a window quote without marine-grade hardware is a quote for a callback. We carry Simonton and PGT lines specifically because they hold a factory finish under salt spray, and we install them with stainless fasteners as the baseline, not an upsell.
Why Barrett & Sons Construction Is Sausalito’s Preferred Windows & Doors Company
Most window companies in the Bay Area treat Sausalito like any other Marin zip code. It isn’t. The fog that rolls through the Gate every afternoon carries salt and moisture that settles on frames, tracks, and flashing. A window that lasts fifteen years in Terra Linda lasts eight here if it’s spec’d with inland hardware. We know that because we’ve pulled enough corroded frames out of Sausalito homes to see exactly where they fail.
Our name is on the truck. Tom Barrett’s sons run the crews, and Tom still walks job sites in 94965 and 94966. When a Sausalito customer calls about a sliding door that seized up or a window that won’t seal against the wind, a live person answers the phone, 24 hours a day. The person who shows up to do the estimate is the person whose name is on the contract, and the estimate is free.
Every window or door job we do in Sausalito includes a written scope of work, written change orders before any price moves, and permits pulled where the job requires them. We back the finished work with our 90-Day Done Right Promise: if it’s not done right, Tom comes back and makes it right, one call.
We’re proud to be one of the Windows & Doors teams that Sausalito homeowners call when they want the job done once. You can look up Tom’s license number before you sign anything. Ask anyone on your street, or check it yourself.
Our Windows & Doors Services in Sausalito
Window Installation
New window installation in Sausalito means more than setting a frame in a rough opening. On hillside homes, we flash the head trim properly so fog-driven moisture can’t sit against the frame and rot the surrounding framing. On floating homes, we use marine-rated lumber and stainless or hot-dipped galvanized fasteners that hold up to constant moisture from below and salt air from above. A typical window installation here runs $4500 to $15000 for a full replacement project, depending on the number of openings and whether we’re working at street level or hand-carrying up steps.
Door Installation
Entry doors on Sausalito hillsides take direct wind and salt exposure. We install doors with composite or fiberglass frames that don’t warp like wood and don’t pit like aluminum. Hardware gets upgraded to stainless as a matter of course. If your existing door is original to a 1960s or 1970s hillside home, there’s a good chance the subfloor around it has dry rot from decades of moisture trapped against unflashed thresholds, and we’ll address that as part of the written scope, not as a surprise change order.
Window Replacement
We tell Sausalito homeowners the truth: a window that’s fifteen years old here is likely already failing, even if it looks fine from the curb. Powder-coated aluminum frames pit within five to seven years of salt spray exposure, and once the factory seal goes, air leaks around the sash and your heating bill climbs. We replace old aluminum frames with vinyl or fiberglass units rated for coastal exposure, with stainless hardware and properly flashed openings. Window replacement in Sausalito typically runs $4500 to $15000 for a whole-home project.
Impact Windows & Doors
Impact-rated windows and doors are not just for hurricane country. On Sausalito’s exposed hillsides, wind gusts off the Golden Gate can hit 60-plus miles per hour in winter storms. Impact glass gives you protection from flying debris and a tighter seal against wind-driven rain. Impact window installation in Sausalito runs $8000 to $25000 depending on the size and number of openings. We install PGT impact units and CGI frames when the job calls for it, with the same marine-spec hardware we use on every coastal job.
We also handle sliding and patio doors, custom windows, glass railings, and hurricane shutters and protection. Each one gets the same approach: scope in writing, allowances in writing, change orders in writing.

Trusted Brands We Service in Sausalito
We install Simonton vinyl windows, PGT impact-rated units, and Ply Gem lines, and we stock replacement hardware and tracks locally so Sausalito customers aren’t waiting two weeks for a part. We service existing Andersen and Marvin windows and doors as well, because a lot of hillside homes above Bridgeway were built with premium wood frames in the 1970s and 1980s, and those frames often just need new seals, fresh stainless hardware, and re-flashing rather than a full tear-out. If you’ve got a brand we didn’t name, call us. We’ll tell you honestly whether it’s worth repairing or replacing.
Common Windows & Doors Problems We See in Sausalito Homes
- Pitted aluminum frames. Powder-coated aluminum window frames on Sausalito homes pit within five to seven years from salt spray. Once the factory coating breaches, air leaks around the sash and the frame starts to oxidize, which is why we specify vinyl or fiberglass with stainless hardware as the coastal baseline.
- Seized sliding door tracks. Roller tracks on sliding glass doors corrode and seize in marine air. The door jumps the track or refuses to close tight against fog-driven moisture, which leads to water intrusion at the threshold and eventually rot in the subfloor.
- Dry rot under unflashed head trim. Hillside homes catch moisture at the top of window openings. When head trim isn’t flashed correctly, water sits against the frame, and the surrounding framing rots. We see this on nearly every 1960s-era hillside home we open up above Spring Street.
- Faded, warped vinyl frames. Intense direct sun combined with salt haze breaks down lower-grade vinyl window frames within a decade. Sashes deform, seals fail, and the window stops closing square. If your home faces southwest toward the Gate, this is likely already happening.
Pricing for Windows & Doors in Sausalito, CA
Here is what you should budget for window and door work in Sausalito, with the marine-spec materials factored in from the start:
| Service | Price Range in Sausalito |
|---|---|
| Window Replacement (marine-spec frames and hardware) | $4500 - $15000 |
| Impact Window Installation | $8000 - $25000 |
The honest truth about pricing in Sausalito: labor costs more here because access costs more. On a steep street with no driveway, our crew stages materials at the curb and hand-carries every panel up 60 to 100 steps, sometimes more. A sliding patio door panel weighs 90 pounds. That labor is real, and it’s in the estimate up front, because a contractor who doesn’t account for it will either underbid and scramble or hit you with a change order mid-job. Our estimates are free, they’re in writing, and they include the full access plan. Call (877) 610-1318 to schedule yours.
One thing that surprises people: marine-spec stainless hardware typically adds 8 to 12 percent to the hardware line item on a full window replacement job. It is not optional in Sausalito. The cheap inland spec costs more within a decade, because you’ll be paying for the same replacement twice.
We recently replaced three sliding patio doors on a hillside home above Spring Street. The original aluminum frames had pitted and seized from salt-laden fog. Our crew hand-carried each 90-pound door panel up 82 steps after the crane set the new units at the curb, then installed marine-grade stainless tracks and stainless hardware. The final inspection sign-off came three weeks after the rough-in, and the homeowner saved a punch-list call-back by approving our written scope of work in advance.
If you’re looking at a quote and wondering whether it’s too high, bring it to us. We offer a Free Second Opinion on Any Written Estimate, and we’ll tell you honestly whether the materials spec’d will hold up in Sausalito or fail within the decade. There’s No Trip Charge Inside the County, and if you’re a senior or veteran, you get a permanent 10% discount.

FAQs - Windows & Doors in Sausalito
Sausalito sits directly at the mouth of the Golden Gate, in one of the foggiest, saltiest, windiest microenvironments in the Bay Area. That salt-laden marine air settles on window and door frames, tracks, and hardware constantly, and unprotected aluminum pits measurably faster here than in Mill Valley or Tiburon, which are protected just enough by the hills. Marine-grade stainless or hot-dipped galvanized hardware is the baseline spec in Sausalito, not an upgrade. Call (877) 610-1318 if your existing frames are pitting or your doors are seizing.
Yes, we’ve installed sliding and patio doors on floating homes throughout Sausalito, including along Richardson Bay off Gate 5 Road. These jobs require marine-rated lumber, stainless or hot-dipped galvanized fasteners, and close attention to flotation hull clearance and dock restraints. We also coordinate with the required permitting for below-waterline and dock-adjacent work. Our scope of work is always written, and every permit is pulled before work starts.
Marine-spec stainless hardware typically adds 8 to 12 percent to the hardware line item on a full window replacement in Sausalito. On a $10,000 job, that generally works out to roughly $300 to $600 more in hardware costs than an inland-spec quote. We build it into every Sausalito estimate from the start, because skipping it means paying for the same replacement twice within a decade. We’re happy to walk you through the line items on your estimate, and there’s no charge for that conversation.
Many do. On the steepest residential streets in Sausalito, particularly above Spring Street, there is often no driveway or alley access, and the only way to get large window or door units to the house is a crane lift to the curb or a hand-carry up 60 to 100 steps. Our estimates include the full access plan, so the labor cost is on paper before you sign, not a surprise in the middle of the job. If your hillside lot has no street-level truck access, tell us when you call and we’ll plan for it from the first site visit.
An inspection sign-off is the Marin County building inspector’s official approval that the installed windows meet current code for structural framing, flashing, and egress. For window replacement jobs in Sausalito that require a permit, we pull the permit, do the work, coordinate the inspection, and walk away with a signed final. The permit inspector works for you, not for me, which is exactly why we like him on the job. Call (877) 610-1318 for your free estimate, and we’ll tell you upfront what your project will require.
