AfterAndersen Construction in San Francisco, CA | Barrett & Sons Construction
We’re Barrett & Sons Construction, an independent Andersen service provider serving San Francisco homeowners. Our crews have rebuilt and replaced Andersen windows and patio doors in hundreds of San Francisco Victorian and Edwardian wood-frame homes, so we know how Andersen’s joinery, sash hardware, and seal systems behave when retrofitted into 100-year-old openings that have settled out of square. What makes our Andersen work here different is simple: we understand the soft-story retrofit ordinance, the fog, and the bay mud the way only a local crew can. Call (877) 610-1318 for a free estimate.
Why San Francisco Residents Choose Us for Andersen Service
Tom Barrett grew up in the San Fernando Valley, not far from the old stretch of Van Nuys Boulevard where his dad used to take him to watch crews pour foundations on weekends. He learned the trade at Los Angeles Trade-Technical College, starting with framing and finishing with enough hours in the field to know that the job never lies. For the better part of two decades he’s been building and remodeling homes, and people around San Francisco know him for showing up when he says he will and not cutting corners when nobody’s looking.
We’re independent Andersen service specialists, not authorized by Andersen. That matters because our retrofit expertise means we can adapt Andersen’s modular frames to San Francisco’s seismic and moisture realities without voiding the original product warranty. We use genuine Andersen replacement parts, such as sash corner keys, weatherstrip, rollers, and operator hardware, for field repairs because aftermarket components can void the Andersen warranty and rarely match the original factory tolerances. Our Andersen sales & service experience runs deep, and we’ve built our reputation on getting it right in old buildings that fight back.
Every scope, every allowance, every price change arrives as a written change order before work happens. Permits pulled and inspections signed on every eligible job. And our 90-Day Done Right Promise is written on every contract, not buried in fine print: if it’s not done right, Tom comes back and makes it right, one call.
Common Andersen Construction Problems We Solve in San Francisco
- Swollen sashes and paint failure on 400 Series and A-Series wood interiors. San Francisco’s persistent marine layer and fog cause the wood interior on older 400 Series and A-Series sash to swell, leading to paint failure, sash sticking, and hairline cracks at the bottom rail joints. We see this constantly in the Mission and SoMa flats. The fog never really burns off the way it does inland, and wood that never dries out will move.
- Racked frames and gapped weatherstrip on 200 Series double-hungs after soft-story retrofits. In pre-war row houses with soft-story retrofits, the added lateral bracing and foundation shifting can rack existing Andersen window frames out of square, causing the weatherstrip to gap and drafts on 200 Series double-hungs. The window still looks fine from the street, but you’ll feel the cold air on your hand.
- Corroded hardware and pitted cladding on E-Series units near the waterfront. On bay-view windows and sliding patio doors in SoMa and the northern waterfront, salt-laden air accelerates pitting on the exterior cladding hardware and corrodes the zinc/aluminum corner keys on E-Series units. Ocean air does in five years what inland air takes twenty to do.
- Binding patio door rollers from bay mud settlement. Bay mud subsidence in ZIPs 94105, 94107, and 94103 causes slight uneven settlement that binds Andersen gliding patio door rollers and throws off the interlock alignment. The door starts dragging on one side, then the lock stops lining up. It’s not the door’s fault, it’s the ground underneath it.
- Flashing failures around Andersen skylights and roof windows. Fog-driven moisture works its way under flashing that would hold up fine in a drier climate, and once the seal is compromised, the fog makes sure it never dries out. We see this most on west-facing and north-facing slopes in San Francisco’s outer neighborhoods.
Andersen Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s Soft-Story Retrofit Ordinance, Chapter 4D of the SF Building Code, is now triggered for thousands of pre-1978 wood-frame multi-unit buildings with tuck-under garages across the Mission, SoMa, and Tenderloin. Any new Andersen window or patio door installation in those buildings must be engineered to work with the new steel moment frames or plywood shear walls without compromising the envelope seal. Our Andersen retrofit work in San Francisco often requires custom shim packs and jamb extension kits to keep the factory weatherstripping functional after the structure has been stiffened. A homeowner in the Mission or SoMa cannot just order windows and hope for the best, because the day the DBI inspector signs off on the soft-story work, the windows have to already be correct. That’s the reality our crews deal with every week, and it’s why our San Francisco service area work always starts with the building’s structural history, not just the window opening.
Andersen Models & Products We Service in San Francisco
We work on the full Andersen line: 400 Series Woodwright with wood interior and vinyl-clad exterior, 200 Series, A-Series, formerly Architectural Series, and E-Series, the old Eagle aluminum-clad wood line. For field repairs, we stock genuine Andersen sash corner keys, weatherstrip, rollers, and operator hardware so we’re not waiting on a parts shipment from the Midwest when a San Francisco homeowner is feeling the fog through a failed seal. For units beyond economical repair, we recommend a full replacement with a current Andersen model rather than patching old frames that have already racked or rotted in San Francisco’s damp, fog-heavy climate. We also handle our Kitchen Remodeling in San Francisco, roof replacement around Andersen skylights, and small or partial kitchen remodels that involve Andersen door retrofits.

What drives the cost in San Francisco is the age of the openings, the condition of the surrounding framing, whether a soft-story retrofit has changed the structure, and whether DBI requires additional seismic or lead-related sign-offs. Our free estimate is a written, line-item quote, and every change order after that arrives in writing before work proceeds. Call (877) 610-1318 for specifics on your building.

FAQs - Andersen Construction in San Francisco
Yes, in most cases. San Francisco’s Department of Building Inspection requires permits when window replacement involves structural changes, and in soft-story retrofit buildings, the window work often ties directly into the retrofit scope. If the opening has shifted or the frame needs re-shimming to work with new shear walls, the permit is not optional. Call (877) 610-1318 and we’ll check your building’s status before you spend a dollar.
Yes, we can. The trick is the old weight pockets. We remove the cords and weights, fill the pockets with insulation, and install the A-Series unit with custom jamb extensions so the new window sits plumb in an opening that hasn’t been square since the 1890s. This is routine work for our San Francisco crews, not a special-order nightmare.
They can be, but the key is the exposure. The 200 Series has a vinyl-clad exterior that handles moisture well. The wood interior needs attention because west-facing fog means the interior side of the sash sees more damp air than you’d expect. We recommend 200 Series for those facades with proper exterior flashing and a breathable interior paint system. For an exact recommendation for your block, call (877) 610-1318.
That conversion runs $4,130 to $11,800 in San Francisco, and when there’s an existing Andersen window in the shower wall, we address it before tile goes up as part of our San Francisco Bathroom Remodeling. That means checking the sash for water intrusion, replacing weatherstrip if needed, and flashing the sill to direct water away from the wall cavity. Skipping that step is how showers rot from the inside out. Call (877) 610-1318 for a written estimate that includes the window scope.
We level the track, replace the rollers with genuine Andersen parts if they’re worn, and re-shim the header so the door panel sits square again. We cannot fix the bay mud, but we can adjust the door so it operates smoothly for years on a foundation that’s moving a fraction of an inch at a time. Estimates are free; call (877) 610-1318.
