PGT Construction in Redwood Shores, CA | Milpitas Construction
We’re an independent general contractor providing PGT window and door service throughout Redwood Shores. The quick answer: if you own a PGT unit in Redwood Shores that’s fogged, leaking, or hard to operate, we repair it when the frame is sound and replace it when the rough opening has already taken water. What makes our PGT work different here is that we plan every job around Redwood Shores’ filled salt-flat geology, high water table, and lagoon-side flood-control rules before we order a single part. Call (877) 752-4194 for a free estimate.
Why Redwood Shores Residents Choose Us for PGT Service
We’ve spent years specifying, retrofitting, and repairing PGT windows and doors across the Peninsula’s marine-influenced housing stock, and we know the product line from the sill pan up. Redwood Shores homeowners call us because we can tell them exactly which PGT series they have, whether the failure is the glazing seal or the frame, and whether the repair is worth doing. That’s the difference between a contractor who’s installed a few PGT units and one who’s rebuilt them on lagoon-side townhomes where the aluminum threshold corroded through. PGT sales & service is a core part of what we do because we’re a full-scope general contractor who actually understands the brand, not a handyman taking a guess.
Ken Stafford, our owner, grew up around the Bay and has spent his working life watching what marine air does to building materials. He’ll tell you flat out when a PGT window is worth restoring and when you’re throwing good money after bad. We’re an independent contractor, not authorized or sponsored by PGT, and that’s exactly why we give straight answers. Our General Contractor in Redwood Shores specs OEM replacement parts when the frame is sound, and quality aftermarket sealing components when OEM is discontinued or doesn’t make financial sense. One call, one contractor, and no finger-pointing between trades.

Common PGT Construction Problems We Solve in Redwood Shores
- Fogged insulated glass on bay-facing PGT windows. Redwood Shores sits between the Bay and the Lagoon, so marine humidity saturates everything. When the glazing seal fails on an older PGT vinyl single-hung, fog creeps between the panes and never clears. We replace the failed glazing unit when the frame is healthy.
- Sticking rollers and corroded track hardware on PGT sliding glass doors. The salt-laden air that rolls off the Redwood Shores Lagoon attacks aluminum tracks and steel rollers without mercy. Doors that once slid with a fingertip now need a shoulder. We source PGT OEM rollers and hardware where they’re still made, or use quality aftermarket parts that hold up better in coastal conditions.
- White corrosion bloom and pitted frames on PGT aluminum units. The bay-facing elevations in Redwood Shores get hit with persistent marine moisture, which shows up as pitting and white powder on unprotected aluminum. We assess whether the frame has lost structural integrity or just needs refinishing and resealing.
- Wind-driven rain leaking past hardened weatherstripping. Winter storms push rain horizontally across the Bay and into Redwood Shores. PGT vinyl sliders and single-hungs from the 1980s and 90s were built with weatherstripping that eventually hardens and fails, letting water track past the sill. The fix is proper weatherstripping replacement, not just adding caulk.
- Rotted rough opening framing behind original PGT installs. The original flashing and sill pans on early PGT installs in Redwood Shores’ slab-on-grade homes often lacked proper back-damming. Water tracks behind the stucco reveal, rots the framing, and nobody knows until we pull the unit. That’s when we rebuild the opening properly and reset the window so it drains the way it should.
PGT Service in Redwood Shores: What Local Conditions Mean for Your Equipment
Here’s what most people don’t know until they start pricing a PGT window replacement in Redwood Shores: the entire community was built on filled former salt flats and tidal marsh, which means deep fill and a water table that sits close to the surface. A window replacement here often triggers a geotechnical and dewatering review before a permit is even pulled. On lagoon-side streets like those near the Redwood Shores Lagoon, the HOA and floodplain rules can dictate sill elevations and whether impact-rated glazing is required, all before you order a unit. That combination of geotechnical review, high water table, and Bayfront flood-control oversight is not what a same-sized window job faces in Redwood City or San Carlos. In practice, it means a homeowner can’t just swap a window to the same opening height if floodplain rules now require a different elevation. We plan for that. On a lagoon-side townhome near the Redwood Shores Lagoon, our crew was called for fogged PGT vinyl single-hung windows and a leaking sliding door on the bay-facing wall. The aluminum threshold and sill pan had corroded through. The rough opening framing behind the stucco was damp from years of marine moisture and a flashing detail with no back-dam. We rebuilt the sill pan with proper back-damming, replaced the failed OEM glazing units and door rollers, re-flashed the opening, and reset the units so the floodplain-driven sill elevation and HOA-approved profile were preserved. That’s the difference between doing PGT work in Redwood Shores and doing it almost anywhere else.
PGT Models & Products We Service in Redwood Shores
We service the PGT WinGuard vinyl impact-resistant series, which includes single-hung, casement, and sliding glass door units. We also work on the PGT Aluminum Series, including impact-rated aluminum built for larger openings, and the PGT Vinyl Series non-impact single-hung and slider models that were common in Redwood Shores’ 1980s and 90s planned-developer homes. For replacement sashes, rollers, weatherstripping, and hardware, we source PGT OEM parts where the frame is sound and the manufacturer still produces them. When OEM is discontinued or not cost-justified for an older unit, we use quality aftermarket glass and sealing components and tell you exactly what we’re using and why. We keep common hardware and weatherstripping on hand for faster turnaround on typical Redwood Shores service area repairs, because nobody should live with a fogged sliding door while a part ships across the country.

FAQs – PGT Construction in Redwood Shores
Usually we can, and that’s exactly what we plan for. On Redwood Shores’ stucco-clad planned-developer homes we pull the old unit through the interior or exterior reveal without breaking the stucco finish broader than the rough opening. But if the sill pan has failed and water has already rotted the rough opening framing, there’s no honest way around opening the wall enough to rebuild it. We’ll tell you which situation you’re in before we start. Call (877) 752-4194 for an on-site look.
No, we’re an independent contractor. We are not authorized, sponsored, or warranty-endorsed by PGT. What we offer is direct knowledge of the product line and straight answers on whether a unit is worth restoring or needs replacement.
Most single-unit repairs, like a fogged glazing replacement or roller and weatherstripping refresh, happen same-day or next-day once parts are in hand. Full elevation replacements depend on HOA review, floodplain approvals, and whether the geotechnical review triggers dewatering requirements. We’ll give you a written timeline before work starts.
We use PGT OEM replacement parts where the frame is sound and the parts are still available. When OEM is discontinued or doesn’t make sense on an older unit, we move to quality aftermarket glass and sealing components and tell you exactly what we’re using. The goal is a repair that lasts in Redwood Shores’ marine air, not just a part number.
A PGT sliding door replacement generally runs $4,500 – $15,000 depending on impact-rating requirements and whether the rough opening framing needs rebuilding. If the frame is sound and only the rollers, weatherstripping, and glazing are failing, a repair is usually a fraction of that. The best way to know is a free estimate. Call (877) 752-4194 and we’ll give you an exact number, not a guess.
