PGT Construction in Redwood Shores, CA | Gold Star Contractors
We provide independent PGT window and door service across Redwood Shores, CA, from full replacements to hardware repairs on aging WinGuard and builder-grade aluminum sliders. What makes our PGT work different here comes down to one thing: Redwood Shores sits on engineered fill over bay mud, so we re-square and re-flash openings instead of dropping new units into frames that have shifted. We know how PGT products age in salt fog and on settling ground because we’ve worked on them in these exact stucco tracts for years. Call (833) 382-8544 to schedule a free estimate. We’re an independent contractor, not a PGT dealer or affiliate.

Why Redwood Shores Residents Choose Us for PGT Service
Gold Star Contractors handles PGT work the way our General Contractor in Redwood Shores should: we diagnose the frame, the flashing, and the hardware together, because in Redwood Shores those three things fail as a system. The salt-laden air off the bay pits aluminum frames. The damp marine layer keeps tracks wet. And the fill under these neighborhoods settles enough to rack openings out of square. A window replacement that ignores any one of those will come back to bite you within a few seasons.
Noel Carranza runs our jobs the way he learned coming up through concrete and finish carpentry work: check the structure first, then the product. That discipline matters on PGT service in a place where inspectors expect bay-mud settlement to be addressed, not papered over. We stock genuine PGT rollers, locks, weatherstripping, and glazing so we aren’t waiting on parts when a Redwood Shores homeowner calls with a slider that won’t track. One call, done right, that’s the only way we know how to run a Redwood Shores Home Remodeling job.
We’re an independent contractor, not affiliated with or authorized by PGT. We buy genuine PGT replacement parts because that’s what actually fits their frames and hardware. For broader PGT sales & service context, that independence is exactly why homeowners trust us: we recommend repair or replacement based on what’s best for the home, not a manufacturer’s program.

Common PGT Construction Problems We Solve in Redwood Shores
- Corroded rollers and bound hardware on bay-facing sliders. Salt-laden air off San Francisco Bay oxidizes aluminum frames and fasteners faster than you’d think. PGT sliders that face the water start binding within a few years, and the chalky white residue on the frame is the tell. We replace rollers and locks before they seize completely.
- Clogged weep holes causing water backup. The persistent marine layer keeps PGT tracks damp almost year-round in Redwood Shores. Grit and organic debris fill the weep holes, water backs up into the wall instead of draining, and the first sign is often peeling paint or a musty smell near the sill. Clearing and re-sloping the track is a standard repair here.
- Fogged glass on original dual-pane units. The 1980s and 1990s tract homes along Marine Parkway and Bridge Parkway shipped with builder-grade PGT single-pane and early dual-pane units. Decades of cool, damp bay air on the exposure side means failed seals and fogged glass. We reglaze where the frame is sound.
- Racked frames from fill settlement. Redwood Shores is built on engineered fill, and it settles. When the slab shifts slightly, PGT frames rack out of square, rollers stop aligning, and locks won’t throw. Homeowners often think the window failed. It didn’t. The opening moved. We re-square and re-flash rather than forcing a square replacement into a no-longer-square hole.
- Chalked and pitted aluminum frames. Persistent fog and salt air accelerate corrosion on exposed metal. PGT Aluminum Series sliders from the original build often have pitted frames that look worse every year. We can refinish some frames; when corrosion has gone through, replacement is the honest call.
PGT Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Here’s what most contractors from Redwood City or PGT in San Carlos won’t tell you, because they don’t deal with it daily: Redwood Shores is built entirely on engineered fill in the tidal flats of San Francisco Bay. That means groundwater sits at shallow depth, and the fill compacts unevenly over decades. Window and door openings shift. A PGT replacement on these slabs isn’t a swap; it’s a re-squaring job. We open the wall around the rough opening, check the king studs and header for movement, re-square as needed, and re-flash against the damp bay-side wall before the new unit goes in. Skip that step and a brand-new PGT WinGuard will fight its own frame within a couple of years. Inspectors in 94065 expect settlement to be accounted for. So do we. It’s the single biggest difference between PGT work done right here and PGT work done the generic way.
On a bay-facing two-story stucco home in the Redwood Shores master-planned tracts off Marine Parkway, our crew pulled original PGT aluminum patio sliders that had corroded rollers and clogged weep tracks from years of salt fog. Then we found the shallow-slab frame had racked slightly from fill settlement. We re-squared and re-flashed the openings against the damp bay-side wall before setting new PGT units with genuine hardware. The doors track and lock cleanly now. That’s the job done the way Redwood Shores demands it.
PGT Models & Products We Service in Redwood Shores
We work on the PGT product lines that actually exist in Redwood Shores homes. The PGT WinGuard Aluminum impact-resistant line shows up on newer replacements and storm-rated retrofits. PGT WinGuard Vinyl units are common where homeowners wanted lower maintenance on the bay side. And the PGT Aluminum Series sliding glass doors, the original builder-installed patio sliders from the 1980s and 1990s, are everywhere. Those older sliders are where we do most of our hardware work.
On parts: we use genuine PGT rollers, locks, weatherstripping, and glazing because aftermarket copies rarely align correctly. When OEM is no longer available for a discontinued line, we use quality aftermarket seals and tell you that upfront. The call is always repair if the frame is sound and only hardware or glass has failed. If settlement has racked the opening or the frame is corroded through, we recommend replacement. Chasing a corroded-through frame with new rollers is just burning money slowly.

AfterPGT Service Pricing in Redwood Shores
What you’ll pay depends on what failed and where the unit sits. A fogged lite on a protected side wall is a different job than a racked bay-facing slider that needs the rough opening rebuilt. Here’s where our typical Redwood Shores PGT work lands:

| Service | Typical Range in Redwood Shores |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Impact Window Installation | $8,000 – $25,000 |
| Roof Repair (flashing around PGT openings) | $400 – $1,800 |
| Home Addition (with PGT fenestration) | $45,000 – $130,000 |
A free estimate from us includes a look at the frame, the flashing, and the hardware together, not just a price to swap glass. If the opening has moved, you’ll know before we quote. Call (833) 382-8544 and we’ll walk the job with you.

FAQs – PGT Construction in Redwood Shores
No. Gold Star Contractors is an independent contractor. We are not affiliated with, authorized by, or endorsed by PGT. What that means for you is simple: we recommend repair when repair makes sense, and replacement when it doesn’t. We use genuine PGT parts because they fit, but no manufacturer program dictates how we advise our Redwood Shores clients.
Salt fog corrodes exposed fasteners and flashing, and the persistent marine layer keeps everything damp long enough for that corrosion to bite deep. Around PGT door openings, we see rusted flashing, failed caulk joints, and deck hardware that’s pitted and weakened. The fix is replacing corroded flashing with properly lapped and sealed materials, and upgrading fasteners to marine-grade where the exposure is direct. Call (833) 382-8544 for an exact quote. Estimates are free.
OEM first, always. Genuine PGT rollers, locks, weatherstripping, and glazing are what we stock and install. They align correctly with PGT frames and hardware. We’ll use a quality aftermarket seal only when PGT no longer supplies the part for a discontinued line, and we’ll tell you before we do it.
Most single-unit replacements take one to two days on site. If the rough opening needs re-squaring due to fill settlement, add time to re-frame, re-flash, and let any patching set before the new unit goes in. Home additions with PGT fenestration obviously run longer. We’ll give you a written schedule before work starts.
Most impact window installations in Redwood Shores run $8,000 to $25,000 depending on the number of units, the size, and whether the openings need re-squaring or re-flashing first. The settlement factor is real here: a straightforward swap in a stable opening costs less than a racked bay-facing wall. Call (833) 382-8544 for a line-item quote. Free estimates, no charge to look.
