PGT Construction in San Francisco, CA
We provide independent PGT sales & service across San Francisco, from window replacement and impact retrofits to full home additions where PGT units are part of the envelope. What makes our PGT work different here is that we don’t treat a window as a standalone product. In a city of 1900s balloon-frame Victorians, soft-story apartments, and hillside cripple walls, every PGT unit has to be re-flashed, re-shimmed, and squared against a hundred-year-old rough opening. Call (877) 373-9230 for a free estimate.
Why San Francisco Residents Choose Us for PGT Service
We know the difference between a PGT WinGuard Vinyl double-hung that just needs a new sash and one whose water intrusion started at a failed flange behind original redwood siding. You don’t learn that from a parts catalog. You learn it opening walls in Noe Valley and the Richmond, where fog-driven moisture has been working on the framing for a century. Noel Cardenas has spent years pulling apart old construction to see where it fails, and he’s built our PGT service around that: find the root cause first, replace what’s actually failing, and never upsell a full window swap when a glazing unit and re-flash fixes the problem.
We’re an independent PGT service provider. That’s a feature, not a disclaimer. We’re not pushing whatever the factory wants moved this quarter. We spec the right unit for your opening and your exposure, and we tell you straight when your existing PGT window is worth saving and when patching would just be buying time.

Common PGT Construction Problems We Solve in San Francisco
- Fogged or failed insulated glass seals on older WinGuard Vinyl units. The marine layer rolls through the Sunset and Richmond most nights, and that damp air cycle stresses sealant on aging glazing units. We see fogging earlier here than in drier Bay Area cities. The fix is usually an OEM replacement glass pack, not a whole window.
- Water intrusion and dry rot at the rough opening. Original flashing on an 1880s – 1920s Victorian fails, and wind-driven rain finds its way behind the PGT flange into old balloon framing. By the time you see a stain on interior plaster, the redwood jamb is usually already soft. We strip back to sound wood, re-flash with modern membrane, and re-set the unit.
- Bowed or out-of-square sliding door frames on hillside homes. PGT sliders are engineered straight, but they get installed in openings that haven’t been straight in sixty years. A settling cripple wall or post foundation on a slope pulls the frame out of square and the door binds. Replacing the slider without fixing the structure underneath is throwing money away.
- Corroded fasteners and degraded weatherstripping on fog-exposed frames. Salt-laden marine air works on metal fasteners year-round. We replace corroded hardware and re-seal jambs before water gets a route into the rough opening.
- Wind-driven rain penetrating past failing jambs during winter storms. A wet El Niño winter exposes every weak seal. If your PGT windows leak only when rain drives from one direction, the weatherstripping or jamb flashing is usually the culprit, and it’s a repair, not a replacement.
PGT Service in San Francisco: What Local Conditions Mean for Your Project
San Francisco’s mandatory soft-story retrofit ordinance is the one local factor that changes how PGT work happens here, and it’s worth a paragraph of its own because it doesn’t happen in Daly City or Oakland the same way. Thousands of wood-frame apartment buildings over garages across 94102 – 94110 are required to have their ground-floor cripple walls braced. Those buildings already carry PGT or comparable replacement windows in the upper floors. Once the retrofit starts, the structure shifts back toward square, and those PGT openings we installed flush ten years ago are now pinching or leaking. We’ve had to open up walls after a seismic brace went in and re-flash, re-shim, and re-set existing PGT units because the rough opening moved a half inch. It’s not the window’s fault. It’s the building settling into its new brace. If you own a soft-story building with PGT units above a garage, plan for that sequencing: retrofit bracing first, then PGT re-setting, then trim and paint. On a steep Edwardian block in 94109, our crew opened a rear wall for a soft-story brace and found the PGT WinGuard sliders above were binding because the underbuilt cripple-wall posts had settled and the rough openings were out of square. We re-shimmed and re-flashed both PGT units after the bracing went in, replaced one fogged sash, and the doors slid clean again without a full replacement.
PGT Models & Products We Service in San Francisco
We work with the PGT WinGuard Aluminum impact-resistant series, both fixed and casement, the WinGuard Vinyl single- and double-hung lines, WinGuard Vinyl sliding glass doors, and the PGT Aluminum Series custom-size fixed and casement units. When a unit is worth saving, we source OEM PGT replacement sashes, glass packs, rollers, and weatherstripping. When OEM for an older series has been discontinued, we use quality aftermarket hardware that matches the original spec, and we tell you which one we’re installing before we order it. For San Francisco turnaround, we keep common WinGuard glazing packs and roller hardware staged so a fogged sash or a sticking door doesn’t sit for three weeks. If frames, flanges, or headers are rotted or out of square beyond shimming, we’re direct about it: replacement beats patching.

AfterPGT Service Pricing in San Francisco
Pricing depends on the unit type, the condition of the rough opening, and whether we’re doing a straight sash replacement or opening the wall to re-flash and re-frame. Here are the ranges we work within:
| Service | Price Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Home Addition | $53,100 – $153,400 |
What drives cost here more than the window itself is what we find when we open the wall: rotted header stock, missing flashing, out-of-square framing, or a cripple wall that needs bracing before we even set the new unit. A free estimate includes all of that assessment. Call (877) 373-9230 to schedule yours, and we’ll give you a written line-item quote before any work starts.

FAQs – PGT Construction in San Francisco
It depends on your block’s historic designation, but in most San Francisco districts with 1880s – 1920s housing stock, a direct like-for-like window replacement does not trigger a full discretionary review so long as you’re not changing the opening size, the number of openings, or the visible muntin pattern. We help you confirm what’s allowed before you order anything. Call (877) 373-9230 and we’ll walk through your specific property.
Usually not. A sticking slider on a hillside San Francisco lot usually means the opening fell out of square because the cripple wall or post foundation settled. We re-shim the frame, re-flash the rough opening, and replace worn rollers before recommending a new door. New doors in a settled opening will stick too. Call (877) 373-9230 for an assessment, and we’ll tell you honestly which path makes sense.
Because cool, damp marine air cycles against the glass daily in fog-belt neighborhoods like the Sunset, Parkside, and the Richmond, and older WinGuard Vinyl units use sealant that hardens and micro-cracks after years of that stress. Once the argon or krypton fill has leaked, the glass pack is done. We replace the glass, not the whole frame, and the fogging stops. Call (877) 373-9230 for a quote on replacement glazing.
It shouldn’t, but it can shift openings enough that windows and sliders that worked fine before start binding or letting in water. Whenever we sequence PGT work alongside a soft-story brace, we re-shim and re-flash affected openings after the brace goes in. It’s the only way to keep the units square and dry. Call (877) 373-9230 before your retrofit starts so we can plan the PGT re-set into the timeline.
It can, depending on the project. Impact-rated glazing is accepted as a life-safety upgrade in many retrofit and addition reviews, and on some upper-floor replacement scopes, having a documented impact product already specified can reduce questions during plan check. We don’t promise permit outcomes, but we do help you document the spec correctly. Call (877) 373-9230 and we’ll tell you what we’ve seen move through DBI recently.
