PGT Construction in San Francisco, CA | Ashford Contractors
We provide independent PGT window and door service across San Francisco, from fog-belt Outer Sunset to the soft-story Victorians of the Mission District. What makes our PGT work different here is straightforward: we know how these units actually behave in this city’s marine moisture, on these hillside lots, and inside these 1880-1920 wood-frame buildings. If you need a PGT repair, replacement, or full installation on an addition, call (877) 752-3868 for a free estimate from a contractor who has done this on your block, not just in your zip code.
Why San Francisco Residents Choose Us for PGT Service
We have spent years installing and servicing PGT windows and doors across San Francisco’s older wood-frame housing stock, including PGT service in Noe Valley. That experience is not generic. It comes from pulling PGT WinGuard sliders out of racked soft-story openings, re-glazing fogged units on west-side exposures, and re-flashing rough openings that original installers never detailed for wet-winter wind-driven rain. Glen Mossier, our owner, grew up watching lagoon-side homes in Foster City get rebuilt after water damage, and he learned early that good construction is what keeps a house standing through decades of Bay Area weather. That same standard applies to every PGT unit we touch in San Francisco. We are an independent contractor with deep product familiarity, not affiliated with, authorized by, or endorsed by PGT. When you call, you are talking to the crew that will actually do the work, and we speak the product language fluently. One contractor. Every system.

Common PGT Construction Problems We Solve in San Francisco
- Roller and track wear on PGT sliding glass doors. Fog-belt homes in San Francisco push marine moisture and grit into the track, and the panel starts to drag or jump the rail. We replace OEM rollers, clean and re-align the track, and set the door so it does not bind again next fog season.
- Condensation and seal failure in insulated glass units. On cool, foggy west-side exposures like the Outer Sunset and Richmond District, PGT units commonly show permanent haze or interior fogging between panes. That is a failed seal, and we tell owners honestly when a re-glaze is worth it versus a full replacement.
- Frame and sill rot at the rough opening. Original flashing on older PGT installations was often not detailed for persistent wet-winter wind-driven rain. We see rot in the sill and jamb that must be cut out and re-flashed before a new unit goes in, otherwise the replacement fails the same way.
- Hardware corrosion on aluminum-clad and steel-frame PGT units. Hinges, handles, and multipoint locks pit or seize in neighborhoods near the coast-influenced air. We source OEM PGT hardware where available and use quality aftermarket parts only when the original is discontinued or lead times would leave an opening exposed.
- Out-of-square frames on settled soft-story and hillside structures. San Francisco’s soft-story rowhouses shift, especially after a garage-level retrofit. That shift racks window and door frames, and a like-for-like swap will fail again unless we correct the opening first with shims, anchors, and proper flashing.
PGT Service in San Francisco: What Local Conditions Mean for Your Equipment
Here is the part that flat, inland Peninsula cities do not impose on a window scope: San Francisco’s Seismic Hazard Mapping Act review. PGT window and door openings on projects in mapped Liquefaction and Landslide Zones, including much of South of Market and the eastern waterfront, can trigger geotechnical reports and added foundation requirements before openings are even framed. That geotechnical sequencing, plus Planning Department discretionary review, is a permit path that a homeowner in Foster City or Belmont never has to think about for a window replacement. In San Francisco, it can add weeks and thousands of dollars to a project that looks simple on paper. We have walked enough PGT openings through this process to know which questions the Planning Department and the geotech will ask, and that means fewer surprises for you. Glen put it plainly to a homeowner on a SOMA loft conversion: the hazard zone review does not care what brand of window you picked. Build it right the first time, and you won’t be rebuilding it in ten years.
PGT Models & Products We Service in San Francisco
Our PGT sales & service work covers the full product range: WinGuard Aluminum impact-resistant series, WinGuard Vinyl impact-rated windows and sliding doors, the Architectural Series with aluminum-clad wood, and Premier Vinyl single-hung and sliding glass door lines. We source OEM PGT glass, rollers, weatherstrip, and hardware where the unit is still serviceable. When OEM is no longer made or lead times would leave a San Francisco opening exposed to the next rain cycle, we use quality aftermarket parts and tell you exactly what we are installing and why. We keep common PGT hardware on hand for faster turnaround in the city.

AfterPGT Service Pricing in San Francisco
What drives the cost on a PGT scope in San Francisco is the condition of the opening, not just the unit itself. A straight window replacement with a clean, square opening runs one number. A soft-story Victorian where the frame has racked, the flashing is rotted out, and the permit path runs through the Seismic Hazard Mapping Act review runs a different one. Here are the ranges we work within for San Francisco:
| Service | Price Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Home Addition | $53,100 – $153,400 |
Every estimate is free and written line-item by line-item, so you see exactly where the money goes before you sign. Call (877) 752-3868 and we will walk the opening with you and price it out.

FAQs – PGT Construction in San Francisco
In many San Francisco Victorians and Edwardians, yes. The existing opening was likely framed 100 years ago, and if the soft-story garage below has shifted or settled, the frame will be out of square, and the sill may have rot from decades of wet-winter exposure. A like-for-like swap without correcting the opening will fail again, often within a couple of fog seasons. Call (877) 752-3868 and we will inspect the opening before quoting, so you know if the scope is a swap or a rebuild.
That interior fogging or haze is a failed insulated glass seal, and it is far more common on San Francisco’s west-side and fog-belt exposures where persistent marine moisture sits against the unit and temperature swings stress the seal. Once the seal fails, the gas escapes and moisture works in. Re-glazing can fix it if the frame is sound; if the frame is also rotted or racked, replacement is the honest answer. Call (877) 752-3868 for a free look.
Most dragging PGT sliders in San Francisco are a roller and track problem, not a door problem. Marine grit and moisture bind the track, the rollers wear flat, and the panel drags. We replace the OEM rollers, clean the track, and re-align the panel, and the door runs clean again. Replacement is only the answer when the frame itself is racked or the glass seal has failed. Call (877) 752-3868 and we will tell you which one you are looking at, without pushing a sale.
Does a permit apply in San Francisco? Yes, in most cases, and the hazard zone absolutely matters. If your building sits in a mapped Liquefaction or Landslide Zone, which includes much of South of Market, Visitacion Valley, and the eastern waterfront, the Seismic Hazard Mapping Act review can trigger geotechnical reports and foundation requirements before the openings are even framed. We handle that permit path as part of the scope, not as a surprise add-on. Call (877) 752-3868 and we will check your address against the hazard maps before we quote.
Yes, and this is where product familiarity earns its keep. PGT’s Premier Vinyl single-hungs and Architectural Series aluminum-clad wood units can be spec’d in sizes and configurations that hold the original sightlines on an Edwardian, so the addition does not look like an afterthought stuck to the side of a period house. We have done exactly that on more than one Edwardian in San Francisco, and the result reads like it was always there. Call (877) 752-3868 for a free estimate.
