PGT Construction in Tiburon, CA | Milpitas Construction
We provide independent PGT window and door installation, replacement, and repair across Tiburon, and we’re one of the few contractors in Marin who stock OEM-compatible PGT parts locally. What makes our PGT work different here is simple: we understand that every project on this peninsula has to survive salt air, steep slopes, and a design-review board that notices everything. Call (877) 752-4194 to schedule a free estimate.
Why Tiburon Residents Choose Us for PGT Service
PGT makes a serious coastal window. The WinGuard Aluminum and Vinyl lines are built for hurricane zones, which means they handle Richardson Bay wind and salt spray better than most. But even the best window fails when it’s installed wrong, flashed wrong, or specced for the wrong exposure. Ken Stafford, our owner, grew up in the Bay Area and spent two-plus decades building and remodeling homes that hold up through soil shifts, wet winters, and marine air. He’s the reason we don’t cut corners on flashing, fasteners, or rough-opening prep. We’ve been called to Tiburon Home Remodeling jobs where a previous contractor hung a PGT unit without stainless hardware, and within three years the frame was pitted and the sash wouldn’t seal. That’s the kind of thing we fix properly the first time.
We’re a full-scope general contractor, not a window-and-door specialty shop. That matters on this peninsula, because a window replacement on a hillside lot often involves siding, flashing, drainage, and sometimes structural work. Same team, same contract. You get PGT sales & service expertise without juggling five different subs.

Common PGT Construction Problems We Solve in Tiburon
- Salt-air corrosion on bay-facing elevations. Tiburon homes that face Richardson Bay get hit constantly with salt-laden wind. Older PGT aluminum frames, especially WinGuard units where the factory finish has worn through, start pitting at the corners and around fasteners. We replace corroded hardware, clean and re-coat frames where possible, and use stainless fasteners on every coastal-facing installation.
- Wind-driven rain past worn weatherstripping. The winter storms that sweep across the bay push rain sideways. PGT vinyl and aluminum units rely on glazing seals and weatherstripping to stay dry. Once those degrade, water gets into the track, the sill, and eventually the wall cavity. We see it most often on single-hung windows that face southwest toward the Golden Gate.
- Racked frames from hillside settlement. Tiburon’s clay soils move with seasonal rain. Add a steep grade and a pier-and-grade foundation, and you get differential settlement that twists window and door openings out of square. A PGT slider that worked fine for twenty years suddenly binds, won’t latch, or leaves a gap at the corner. We don’t just shim the unit; we check the rough opening and reframe when needed.
- Failed seals and fogged glass from the marine layer. The fog that rolls over the Tiburon Peninsula puts constant moisture against window seals. Older PGT insulated glass units lose their argon fill and start fogging between the panes. Once the seal is gone, the window loses thermal performance and looks bad from inside and out.
- Design-review mismatches on replacement units. Tiburon’s design-review process often requires replacements to match the original window profile and divided-light pattern exactly. We’ve had projects where a stock PGT unit got rejected because the muntin width was off by a quarter inch. We handle the custom sizing and grid configuration so you don’t get stuck in review limbo.
PGT Service in Tiburon: What Local Conditions Mean for Your Equipment
The single biggest factor in Tiburon is the design-review process. Unlike most Marin towns, Tiburon and Belvedere review window and door replacements on nearly every elevation, including rear elevations visible from the bay. If your original windows had a specific divided-light pattern, a specific frame depth, or a specific color, the replacement has to match. That means most PGT work here is custom-ordered, not pulled off a shelf. Lead times stretch, and a homeowner who already ordered a stock unit can end up starting over. We’ve walked through that process enough times to know exactly what the town’s reviewers look for, and we order to spec the first time with help from our General Contractor in Tiburon. On the hillside streets in Old Tiburon and Belvedere, the same review applies even when the only person who’ll see the window is a passing kayaker. It’s a specific constraint, and it shapes every PGT project we touch on this peninsula.
PGT Models & Products We Service in Tiburon
We install, replace, and repair the full PGT line: WinGuard Aluminum, WinGuard Vinyl, the standard Aluminum Series, and the Vinyl Series. For critical components like rollers, locks, and weatherstripping, we use OEM PGT parts to keep the warranty intact and the performance where it should be. When OEM isn’t available or the cost doesn’t make sense on an older unit, we’ll offer a quality aftermarket alternative and tell you exactly what the tradeoff is. We keep common PGT hardware and weatherstripping on hand for faster turnaround on Tiburon jobs, because nobody wants a leaking slider waiting three weeks for a part that costs twelve dollars.
We’re an independent PGT service provider. We are not manufacturer-affiliated or authorized, which means we answer to you, not to a corporate territory map.

FAQs – PGT Construction in Tiburon
Tiburon doesn’t sit in a hurricane zone, so impact-rated windows aren’t a code requirement the way they are in Florida. But homes on bay-facing elevations get real wind and salt exposure, and many of our clients choose WinGuard for the sturdier frame and better seals. If you’re replacing windows on a slope with wind exposure, impact-rated units are a reasonable upgrade, not a necessity. Call (877) 752-4194 and we’ll tell you honestly whether it’s worth the extra cost on your specific lot.
Salt air attacks aluminum frames, fasteners, and hardware, especially within sight of the bay. PGT’s factory finish holds up well, but once it’s scratched or worn, the aluminum underneath starts to pit. We see the worst damage on lower-track corners of sliders and on exposed screw heads. Stainless hardware and regular cleaning go a long way on a Tiburon house.
Yes, and in Tiburon you usually have to. The town’s design review often demands that replacements match the original profile and divided-light pattern exactly. We take the measurements, match the muntin width and frame depth, and order the custom PGT in Chinatown-style configuration that passes review. It adds lead time, but it avoids a rejected application.
Custom PGT units with specific grid configurations and sizing typically run four to eight weeks, sometimes longer during peak building season. Design-review requirements in Tiburon mean we’re almost always ordering custom, not pulling stock. We’ll give you a realistic timeline before you commit, and we’ll coordinate the installation around the review approval.
We do, and it’s a regular part of the job in Tiburon. On a steep Belvedere hillside street with no driveway access, we craned a PGT WinGuard Aluminum sliding door over the house to replace a corroded unit that had been leaking for years. The original opening was out of square due to slope movement, so we reframed the rough opening and installed a new unit with upgraded flashing and stainless fasteners. The homeowner got a weather-tight door that operates smoothly and meets the town’s review requirements. If you’ve got a hillside lot with no easy access, call (877) 752-4194 – we’ll figure out the logistics before we bid the job.
