PGT Construction in San Francisco, CA | Workshop Contractors
We install and service PGT windows and doors across San Francisco, from single sash replacements in Marina flats to full hillside retrofits in Noe Valley. What makes our PGT work different here is simple: we’re an independent contractor who has spent years working on the city’s lot-line Victorians and Edwardians, where a window replacement is rarely just a window replacement. Call (844) 384-3361 to talk through your building.
Why San Francisco Residents Choose Us for PGT Service
Most contractors in San Francisco know PGT as a product line. We know it as a system that has to perform inside buildings that are 100 to 140 years old, often out of square, frequently damp, and always built tight against the neighbor. Noel Figueroa learned framing on job sites before he could legally rent a truck, and he’s carried that framing-first thinking into every window and door opening we touch. When a PGT unit binds in an old header, we don’t shim it and walk away. We look at the rough opening, the flashing, the drainage path, and the party-wall condition before we decide what the fix actually is. That’s the difference between a contractor who installs windows and one who understands the building around them.
We’re also PGT sales & service specialists who stock OEM replacement sashes, weatherstripping, and hardware for common PGT lines, which means less waiting when a fog-belt facade finally gives up a seal. And because we operate as a single-source general contractor, we can coordinate the window work with siding, trim, waterproofing, and even structural corrections under one schedule. You’re not calling three companies to fix one wall.

Common PGT Construction Problems We Solve in San Francisco
- Corner weld separation on vinyl WinGuard sashes. San Francisco’s fog belt keeps facades damp for months at a time. Vinyl expands and contracts with temperature swings, but when it never fully dries, corner welds fatigue and gaskets shrink. We see this most on north-facing elevations and units behind drawn blinds, where condensation sits in the sash pocket. If the welds are clean, we replace the sash. If the frame is compromised, we say so plainly.
- Pitted and oxidized aluminum frames on marine-facing elevations. Original PGT aluminum units on 1980s and 1990s remodels take a beating on the ocean side. Salt air, wind-driven grit, and constant moisture pit the finish and clog the weep systems. Water that should drain out of the frame instead sits against the glazing channel. We clean and restore where the frame is sound, and replace when the pitting has eaten into the profile.
- Sash binding in out-of-square rough openings. On Edwardian and Victorian retrofits, the original rough opening was never square and was never going to stay square. Old headers move. The PGT unit gets blamed for binding or gapping weatherstripping, but the real issue is the frame around it. We reframe, flash, and reset before we install, which is the only fix that lasts.
- Sliding door interlock leaks on hillside and ocean-facing walls. Pacific winter storms drive rain sideways against multi-panel PGT sliders. If the flashing was detailed for a milder exposure, water finds the interlock and the sill. We re-flash the opening, verify the drainage path, and replace worn interlock gaskets with OEM material. On steep hillside lots, we also check the deck drainage above the door, because that’s where half the water actually comes from.
- Fogged glazing from trapped moisture behind interior blinds. San Francisco’s damp-cool cycle means interior condensation is a year-round reality, not a winter-only issue. When PGT insulated glazing loses its seal, the fog doesn’t clear. We replace the glass pack where the frame is serviceable, and we talk honestly about ventilation and blind placement so the new unit doesn’t fail the same way.
PGT Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s the thing about San Francisco that a PGT catalog page won’t tell you: a lot of the city’s “two-story” buildings are actually one story over a full-height basement carved into the hillside. In Noe Valley and Bernal Heights especially, what looks like a straightforward window replacement on the lower level often sits in a wall that’s retaining soil on one side and holding up the floor system on the other. We also handle Visitacion Valley PGT service with the same hillside expertise. A PGT unit in that wall isn’t just a window; it’s part of the drainage and moisture-management system for the entire lower floor. When we open those walls, we routinely find the original rough opening has shifted, the sill is soft, and the flashing was never right for the water load coming down the slope. That’s why our PGT installs on hillside homes always start with the drainage question before the window question. In the Richmond and Sunset districts, the marine layer does its own kind of damage, keeping west-facing frames damp for weeks and testing every seal and gasket on the windward side.
PGT Models & Products We Service in San Francisco
We work on the full PGT residential and light commercial range: WinGuard Vinyl single-hungs and sliding glass doors, the WinGuard Aluminum line, custom PGT Aluminum Series windows and doors, and PGT Commercial Series units including the 700 Series. Parts policy is straightforward. We use PGT OEM sashes, glazing, weatherstripping, and hardware whenever the unit is serviceable and parts are available. When OEM parts are discontinued or on long lead, we turn to quality aftermarket balances and screen components and we tell you that’s what we’re doing. We don’t hide the parts source. Every install gets the same standard: plumb frame, flashed opening, correct drainage, and hardware that operates like it should on day one. Whether it’s one sash in a Marina flat or every opening on a three-story Edwardian, the sequence is the same.

AfterPGT Service Pricing in San Francisco
PGT work in San Francisco is priced by the opening, the access, and the condition of the rough frame. A clean sash replacement on a standard opening is one thing. A lot-line window where the crew has to stage from a neighbor’s yard or a roof is another. A hillside door with water damage behind the sill is another still. The table below gives you honest market ranges for the three PGT-related services we do most in San Francisco, including PGT in Mission District properties. Every estimate includes a site visit, access planning, and a written line-item scope. No numbers change once work starts unless we open a wall and find something we couldn’t have seen from the outside, and we stop and talk before proceeding.
| Service | San Francisco Price Range |
|---|---|
| Window Replacement | $5,310 – $17,700 |
| Impact Window Installation | $9,440 – $29,500 |
| Home Addition | $53,100 – $153,400 |

FAQs – PGT Construction in San Francisco
Yes. In most cases we stage from the interior, set up scaffold over the roof, or coordinate temporary access through a neighbor’s property with a written agreement. Because so many San Francisco homes share party walls with no side yard, we plan the access path before ordering any unit, and we include that coordination in the estimate. Call (844) 384-3361 and we’ll walk your specific lot.
They can. If your building falls under Ordinance 66-15, any wall work at or below the soft-story level may need to be sequenced with the structural retrofit. We coordinate with your engineer and the permit drawings so the window or door opening doesn’t get reframed twice. On some projects, it makes sense to do the storefront or garage-level PGT units as part of the retrofitted envelope, not as a separate permit. Every situation is different, and we’ll tell you what applies to yours.
If the weld has failed but the frame is square and the glazing is intact, we can often replace the sash as a serviceable repair. If the corner separation has allowed water into the sash pocket long enough to compromise the frame, or if the same weld failure exists on multiple sashes, replacement is usually the honest call. We’ll show you the evidence either way. For a diagnosis on your specific units, call (844) 384-3361.
It depends on the building’s status and the scope. Landmarked buildings and some district-listed properties require review for visible exterior changes, including window replacement. We know the San Francisco Planning Department process and we can prepare the submittal documents that show the proposed PGT units in relation to the original sightlines and mullion patterns. Early coordination avoids a stop-work order later. Call us and we’ll help you figure out which path applies.
The marine layer keeps exterior surfaces damp and cool for long stretches, which means interlock gaskets stay wet, weep systems work harder, and condensation forms on the interior glazing when indoor air is warmer. Over time, that continuous moisture degrades seals and finishes faster than a drier climate would. We check interlock gasket condition, sill drainage, and flashing integrity as part of every PGT slider service call. If your door is binding or leaking, call (844) 384-3361 for an assessment.
