PGT Construction in Foster City, CA | San Bruno Construction
We provide independent PGT in Redwood Shores and door service across Foster City, from single-unit repairs to full-home replacements and additions where PGT products are specified. PGT windows and doors are built for coastal conditions, which matters here more than almost anywhere on the Peninsula. What makes our PGT work different in Foster City is that we know exactly how these units fail on engineered fill and lagoon-front lots, and we plan for it from the first measurement. Call (866) 472-1908 to schedule a free estimate.
San Bruno Construction handles the full scope of PGT work: PGT sales & service, repairs, retrofits, and complete window and door replacements. We’re an independent contractor, not a PGT factory operation, so our recommendations are based on what works in your home, not what needs to move off a warehouse shelf. That independence matters when you’re deciding whether to repair a 50-year-old aluminum slider or replace it with a new WinGuard unit.
Why Foster City Residents Choose Us for PGT Service
Foster City’s housing stock is overwhelmingly 1960s and 70s planned-community construction. Single-family homes, townhomes, and low-rise condos built in uniform tracts, most still carrying original windows that predate modern coastal glazing standards. We’ve spent years working on exactly these Belmont PGT service and Foster City homes, and we know the PGT aluminum and vinyl product families that were installed in these neighborhoods.
Noel Carvalho, our owner, grew up just north in San Bruno and trained in construction technology at Skyline College. He’s spent more than two decades running residential projects across San Mateo PGT service areas, including plenty of Foster City homes where the original windows are finally showing their age. That local experience means we don’t guess when a PGT unit is binding or corroding. We know what’s behind the trim, what the flashing looked like in 1973, and what the bayfront air has been doing to it ever since.
We also source OEM PGT replacement parts whenever the frame is still sound. Aftermarket rollers, balances, and weatherstripping often don’t match PGT’s extrusion profiles, and forcing them in creates a repair that fails in two years. We’d rather tell you the honest answer, even when it’s more expensive up front.

Common PGT Construction Problems We Solve in Foster City
Here’s what we actually see on PGT units in Foster City, week after week:
- Corroded aluminum frames and thresholds on lagoon-facing elevations. Salt-laden air off the Bay accelerates corrosion on aluminum window frames, door thresholds, and hardware. We’ve pulled sliders off Shell Boulevard homes where the rollers had seized completely and the frame finish was pitted down to bare metal. Sometimes the frame is salvageable with new hardware; often the smarter move is a vinyl WinGuard replacement.
- Sliders that bind after fill settlement racks the opening. Original 1960s-70s PGT aluminum sliders in Foster City track homes often have worn nylon rollers, and the tracks themselves bind because decades of fill settlement have racked the rough opening slightly out of square. Shim the frame wrong and the new unit leaks. We measure, re-shim, and re-flash so the slider actually travels the way it was designed to.
- Rotted sub-sills and failed perimeter flashing. High groundwater and winter rain on flat fill lots push water against shallow-founded window openings. On older PGT installations, the perimeter flashing was minimal by today’s standards, and we regularly find rotted sub-sills hiding behind intact interior trim. Water intrusion on fill lots doesn’t announce itself until the damage is done.
- Warped vinyl frames on west-facing walls. Intense afternoon sun off the Bay plus bayfront moisture causes older PGT vinyl frames to warp and seals to fail, especially on single-pane or early dual-pane units. The seal failure shows up as fogging between panes, but the warping is what compromises the weather seal.
- BCDC-driven glazing and flashing requirements on lagoon-front homes. Replacing PGT windows on the water side of a lagoon-front property can trigger Bay Conservation and Development Commission review, which may dictate glazing specs, frame materials, and flashing details. An identical replacement two streets inland never sees this. We’ve managed BCDC-driven window scopes and we know what that review asks for before we order the first window.
PGT Service in Foster City: What Local Conditions Mean for Your Equipment
Foster City is almost entirely built on engineered fill and bay marshland. The city was developed in the 1960s and 70s on ground that has been settling ever since, and that single fact shapes more PGT work here than any other. When the fill settles, it doesn’t settle evenly. Window and door rough openings shift slightly, which is why so many original PGT sliders in Foster City bind or leak even when the hardware is in decent shape. A window that worked fine in 1985 is now fighting its own frame.
Homes along the lagoon channels sit on fill with a high water table, and contractors regularly hit water when digging footings. That same water pressure works against shallow-founded window openings from below, while winter rain and wind-driven Bay moisture attack from above. For a Highlands-Baywood Park PGT service or lagoon-front home, that means the flashing and perimeter seal are doing more work than the manufacturer ever anticipated. When we replace PGT units on these lots, we plan for drainage, we re-grade where needed, and we specify flashing details that a home on solid bedrock never requires.
Good construction doesn’t announce itself, it just works, year after year. On Foster City fill, that means doing the unseen work correctly the first time, because the soil and the Bay won’t give you a second chance for free.
PGT Models & Products We Service in Foster City
We work on the full PGT residential lineup, including the WinGuard Aluminum Series, WinGuard Vinyl Series, PremierVue Series, and EnergyVue Series. On Foster City homes, we see a lot of original WinGuard aluminum sliders from the 60s and 70s, plus newer vinyl units in homes that have had partial replacements or additions over the years.
Our parts approach is simple: when the frame is sound, we order OEM PGT rollers, weatherstripping, and hardware. Aftermarket glazing and balances rarely match PGT’s extrusion profiles, and we won’t install a mismatch to save a few dollars. When corrosion or settlement damage has compromised the frame or flashing, we tell you honestly that a full unit replacement is the better long-term move. We keep common PGT hardware stocked for fast turnaround on Foster City repairs, and anything we don’t carry, PGT’s distribution network gets to us quickly.

AfterPGT Service Pricing in Foster City
PGT work in Foster City falls into three main cost buckets, depending on scope. A single window replacement or slider repair sits at the low end; full impact-rated replacements run higher because of the glazing and engineering involved; and a home addition where PGT units are specified is a much larger project with its own permitting and structural requirements.
| Service | Typical Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Home Addition (with PGT windows/doors) | $45,000 – $130,000 |
What drives the cost in Foster City specifically is the condition of the rough opening, the flashing work required on fill lots, and any BCDC review on lagoon-front elevations. Our free estimate includes measurements, a frame assessment, and a written line-item quote so you know exactly what you’re paying for before you commit. Call (866) 472-1908 for an exact quote.

FAQs – PGT Construction in Foster City
Yes, if your home falls within Bay Conservation and Development Commission shoreline jurisdiction, replacing or altering windows on the water side can trigger a BCDC permit review, even for like-for-like replacements. The review may dictate glazing specifications, frame materials, and flashing details. An identical PGT window replacement on the inland side of Foster City needs no BCDC involvement. We can tell you early whether your project is in the review zone, and we coordinate the permit process as part of the job. Call (866) 472-1908 and we’ll check your address.
On Foster City homes, the most common causes are worn nylon rollers, corroded tracks, and frame racking from years of fill settlement on the engineered pad. The original PGT aluminum sliders from the 60s and 70s used rollers that wear down over 50 years, and when the track is also pitted from salt exposure, the window fights you every inch. We can repair many of these with OEM parts when the frame is sound, but if the opening has shifted or the frame is corroded, replacement is often the better investment.
New PGT WinGuard vinyl and aluminum units are engineered for coastal exposure, with corrosion-resistant hardware and glazing designed for wind-driven rain. That said, even a well-made window fails if the flashing and drainage behind it are wrong. On Foster City lagoon-front lots, the perimeter seal and sill flashing are doing the heavy lifting, and those details are where we focus during installation. The window matters, but the installation matters more on fill.
Yes. Fogging between panes means the insulated glass unit has lost its seal, and the desiccant inside the spacer has been saturated. On older PGT dual-pane units, especially west-facing ones that take heavy afternoon sun and Bay moisture, this is common. A failed seal cannot be repaired, only replaced, either as a new IGU or a full sash replacement. Call (866) 472-1908 for a free assessment, we’ll tell you whether it’s a sash swap or a full unit replacement.
Yes. On fill lots, a second-story addition adds load to soil that is still settling, which means we pay close attention to the window rough opening framing, the lintel sizing, and the perimeter flashing. PGT models with reinforced frames and better drainage perform better in these conditions. We also account for the fact that your existing first-floor openings may have shifted over the decades, so the new second-story windows need to be installed with the assumption that this house will keep moving slightly. That’s the reality of building on Foster City’s engineered fill. Call (866) 472-1908 to discuss your addition plans.
