PGT Construction in Alum Rock, CA | San Bruno Construction
San Bruno Construction provides independent PGT window and door service across Alum Rock, from impact-rated WinGuard repairs to full replacement on older stucco homes and hillside parcels. We’re not a PGT dealer or authorized warranty center. What we are is an Alum Rock contractor that has pulled county permits for unincorporated parcels enough times to know exactly where city rules stop and Santa Clara County rules take over. That distinction changes what gets inspected, how the drainage review works, and what the final bill looks like. Call (866) 472-1908 for a free estimate.
Why Alum Rock Residents Choose Us for PGT Service
The PGT windows and doors on Alum Rock homes tend to be older units, often installed before the current county hillside requirements existed. Our crews know the product architecture of the WinGuard impact line and the aluminum 700/800 series well enough to diagnose what’s actually failing, instead of defaulting to a full replacement quote. We source OEM PGT glass, hardware, and weatherstripping where the unit still has serviceable life, and we stock common aftermarket seals and rollers for discontinued series so we’re not waiting two weeks on a freight truck. Noel Carvalho, our owner, trained in construction technology at Skyline College and has spent two-plus decades pulling permits and running projects across San Mateo and Santa Clara counties. He’s the one who reviews your window opening before we order anything, because he knows a racked rough opening on a hillside slab will ruin a new PGT unit as fast as it ruined the old one. We coordinate the trades so you don’t have to. For the full picture, see our PGT sales & service overview.

Common PGT Construction Problems We Solve in Alum Rock
- Aluminum frame pitting and corrosion. Alum Rock’s concentrated winter storms push wind-driven rain hard against hillside-facing elevations. PGT aluminum frames that were never correctly flashed sit wet for days, and the pitting that follows eventually eats through the finish and into the metal. On a south or west exposure above a slope, it happens in half the time it would on a flat San Jose lot.
- Fogged dual-pane WinGuard IGUs. Full summer sun followed by cold winter storms is a brutal thermal cycle for insulated glass. The PGT WinGuard units on Alum Rock homes face more of this swing than coastal properties do, and seal failure shows up as persistent fog or moisture between panes. If the frame is straight and the sash is sound, we replace the glass pack, not the whole window.
- Water infiltration at sill pans and corner joints. Older installations on hillside slopes often skipped proper sill pan flashing. The first solid storm of the wet season drives water behind the frame and into the wall cavity. We rebuild the rough opening, add correct sill pans, and reset the same PGT frames with fresh OEM glass where possible.
- Sliding glass door rollers and hardware binding. Many Alum Rock homes are 1950s to 1970s stucco-and-wood-frame construction, and decades of soil movement on the alluvial fan have skewed door openings slightly. PGT sliding doors start to drag, bind, or refuse to latch. We can often replace rollers and realign hardware; when the opening itself has racked, replacement is the only fix that lasts.
- Unpermitted prior work that surfaces during inspection. Alum Rock has a long history of informal second units and additions that never went through county review. When a window replacement pulls a permit, the county frequently discovers the unpermitted work during inspection. We help homeowners deal with that legalization path without derailing the window job.
PGT Service in Alum Rock: What Local Conditions Mean for Your Equipment
Here’s the thing most window contractors won’t tell you about Alum Rock: because the community sits in unincorporated Santa Clara County rather than the City of San Jose, window and door replacements on hillside parcels trigger county building permits, not city ones like you’d need for PGT repair in San Jose. And the county’s hillside review adds a grading and drainage component that city-only jobs never see. That means a simple PGT window swap on a sloped lot off Alum Rock Avenue can turn into an engineering review of your foundation drainage before the window is even cleared for installation. We’ve handled enough of these to know which elevations trigger the review and which ones slide through, and we build that into the estimate up front instead of springing it on you after demo day. In practical terms, the permit path affects timeline and cost, not the quality of the PGT product itself. But ignoring it means the county red-tags the job, and nobody wants that.
PGT Models & Products We Service in Alum Rock
We work on the PGT WinGuard Aluminum Impact line, WinGuard Vinyl Impact windows, the aluminum Series 700 and 800, and the vinyl Series 200 and 300. Older discontinued series are familiar territory too. Our parts approach is honest: when a PGT unit is still serviceable, we source OEM replacement glass, hardware, and weatherstripping so the warranty and fit stay intact. For discontinued series where OEM is unavailable, we turn to quality aftermarket seals and rollers that match the original profile. Most common parts for Alum Rock homes are available from local suppliers within a day or two, which keeps a repair moving without a long freight delay. Good construction doesn’t announce itself – it just works, year after year.

AfterPGT Service Pricing in Alum Rock
What you’ll pay for PGT work in Alum Rock depends on whether we’re repairing hardware or replacing full units, and whether the county hillside review applies. Here’s where the numbers land on our two most common scopes:
| Service | Price Range |
|---|---|
| Impact Window Installation | $8,000 – $25,000 |
| Window Replacement | $4,500 – $15,000 |
Repairs are a different line item: glass pack replacement, sill pan rebuilds, and roller swaps are priced individually after we see the unit.

FAQs – PGT Construction in Alum Rock
Yes. Because Alum Rock is unincorporated Santa Clara County, window and door replacements that need permits go through the county, not the City of San Jose. On hillside parcels, the county adds a grading and drainage review that city jobs don’t face. We handle the permit paperwork and build the county requirements into your project plan before work begins. Call (866) 472-1908 and we’ll tell you what your specific parcel will require.
Not necessarily. Fogging between window panes means the insulated glass seal has failed. If your PGT frames are square and the sashes operate smoothly, we can replace just the glass pack with OEM PGT glass for a fraction of the full window cost. Frame rot or a racked opening changes that answer fast. Call (866) 472-1908 for a free in-person assessment.
Wind-driven winter rain hits hillside elevations harder than flat lots, keeping frames wet longer and accelerating aluminum pitting and sill pan corrosion. The same pattern shows up on PGT in Seven Trees homes with similar exposure. The steep slopes above the neighborhood also shed water quickly, so a window without proper flashing gets water driven into the wall cavity every storm. We rebuild openings with correct sill pans so repaired PGT units don’t fail the same way twice.
Yes, usually. If the old units are from the PGT aluminum 700/800 series and the frames are still in production, we source matching OEM units. For discontinued series, we’ll spec a current PGT model with the closest sightline and finish, and confirm it before ordering. Matching older aluminum finishes is an art, but we’ve done it on plenty of 1960s Alum Rock homes.
It can. If your permit application triggers a county inspection of the whole parcel, the inspector may flag a long-ago unpermitted addition or second unit, and that can stall the window job until the legalization path is sorted. We’ve navigated this enough times to know how to sequence work and paperwork so the windows move forward while the county process plays out. The same approach works for PGT in Buena Vista properties facing similar county reviews. Call (866) 472-1908 to talk through your situation.
