PGT Construction in Tiburon, CA | Timberline Contractors
We provide independent PGT window and door service across Tiburon, from replacement of fogged WinGuard sliders on waterfront homes to full impact-rated installs on hillside view lots. The thing that sets our PGT work here apart is simple: we plan every job around Tiburon’s access constraints and fog-belt moisture, because those two factors cause more PGT failures and botched replacements than anything else. If you need straight answers about your PGT units, call us at (866) 253-5808.
Why Tiburon Residents Choose Us for PGT Service
We’ve serviced PGT windows and doors across Tiburon’s hillside and waterfront homes for years, and we know how Marin’s fog belt and slope conditions expose installation weaknesses in ways Marin City PGT service and flatland jobs never do. We’re an independent contractor, not authorized by PGT, so our recommendations are based solely on what holds up on the Tiburon Peninsula, not on what a manufacturer’s spec sheet assumes.
Nelson Fung, our owner and our General Contractor in Tiburon, learned the trade at Los Angeles Trade-Technical College and spent years on remodels and mid-size commercial builds before running Timberline Contractors. He’s the one who will walk your property, look at how the original installer flashed the sill, and tell you whether you’re looking at a repair or a replacement. We keep PGT OEM replacement parts on hand for common Tiburon failures: rollers, weatherstripping, corner welds, and glass packs. Faster turnaround, fewer return trips.

Common PGT Construction Problems We Solve in Tiburon
Here’s what actually fails on PGT units in this town, and why:
- Water intrusion behind bay-facing frames. Constant fog and wind-driven rain attack the sill and head flashing. When the original install relied on caulk instead of a proper weather-resistive barrier, water tracks behind the frame and rots the wall sheathing. We see this constantly on older waterfront homes where the caulk has long since gone chalky.
- Racked sashes and failed corner welds on hillside homes. Slope-built houses on pier-and-grade foundations flex slightly with soil movement and temperature swings. PGT units that were shimmed and anchored without allowance for movement develop misaligned sashes, cracked vinyl corners, and drafty seals within a few seasons.
- Corroded rollers and water intrusion at sliding door tracks. Cantilevered decks and stepped foundations funnel runoff toward downhill walls. PGT sliding door tracks on those elevations fill with silt and debris, which grinds the rollers and eventually lets water through the track-to-threshold joint.
- Pitting and finish failure from salt-laden air. Older PGT aluminum units on Tiburon waterfront homes show pitting and chalky finish degradation faster than identical units a mile inland. The salt air also accelerates edge-seal failure in insulated glass, which is why we see so much fogging between panes.
- Fogged WinGuard glass on view windows. Once the edge seal breaches, moisture gets between the panes and you lose the view. This is a replacement glass situation, not a cleaning problem, and the fix has to match the original frame profile or you’ll have a worse leak than you started with.
PGT Service in Tiburon: What Local Conditions Mean for Your Equipment
Because many Tiburon hillside lots have no at-grade staging, PGT replacement windows often have to be craned in or carried up narrow exterior stairs, and that access constraint determines which units can be installed without temporarily removing a deck or railing. On the streets above Paradise Drive and up toward the open space, there’s frequently nowhere to put a materials pile except the road shoulder, and the neighbor’s view easement becomes part of the permit conversation. That reality changes the math on a window replacement. A unit that makes perfect sense on paper may be the wrong choice if getting it to the opening means pulling a railing, renting a crane, and scheduling around the delivery truck’s turning radius. In flat neighboring Corte Madera, PGT in Chinatown, or Mill Valley, a crew backs the truck into the driveway and unloads. Here, we plan the lift first and pick the window second. It’s the only order that works.
On a steep street above the Tiburon waterfront, we replaced fogged PGT WinGuard sliders in a 1980s hillside home where the original install had no sill pan and relied on caulk against the fog-belt rain as part of our Tiburon Home Remodeling work. Our crew staged the new units on the street and craned them to the deck, then rebuilt the flashing with a proper sill pan and WRB tie-in before setting the PGT frames. The result was a dry, code-compliant opening that also met the homeowner’s view and egress needs. That’s the difference between swapping glass and actually fixing the opening.
PGT Models & Products We Service in Tiburon
We work on PGT WinGuard Aluminum impact-resistant windows and sliding glass doors, PGT WinGuard Vinyl impact-rated casement and awning windows, PGT Aluminum Series fixed and operable units built for view exposures, and PGT Vinyl Series single-hung and slider replacement windows. We use PGT OEM replacement parts for glass, hardware, and weatherstripping whenever they’re available. Aftermarket seals and rollers rarely match the original profile, and in this marine environment they fail faster, which means you’re back on the phone in two years. When a frame is sound but seals are shot, we repair. When corrosion or racking is structural, we recommend full replacement with a properly flashed unit. No shortcuts, no magic sealant claims.
We’re an independent PGT service provider, not a manufacturer-affiliated or authorized dealer. That means our call on repair versus replace comes from what we’ve watched fail and hold up on the Tiburon Peninsula, not from a quota. You can browse our PGT sales & service page for more on how we handle the full line.

FAQs – PGT Construction in Tiburon
In many cases, yes. The deciding factor is access: if our crew can carry the replacement sash or full unit up exterior stairs and through the interior, we won’t need to touch the railing. If the opening is only reachable by crane, we may still avoid railing removal by rigging the unit over the deck. Call (866) 253-5808 and describe your lot and the window location, and we’ll tell you which scenario applies before we write the quote.
Bay-facing elevations get constant wind-driven moisture and salt-laden air, which corrodes rollers and fills tracks with silt from runoff off cantilevered decks and stepped foundations. The fix is usually OEM roller replacement plus track cleaning and seal adjustment, but if the threshold-to-track joint has started letting water in, we’ll recommend pulling the door and rebuilding the sill flashing. Call (866) 253-5808 for an inspection.
Many Tiburon hillside homes do require a crane or a careful manual carry up narrow exterior stairs, because there’s no at-grade staging area. We assess the access path during the estimate and include crane logistics in the quote if they’re needed. The window choice itself sometimes changes based on what we can physically get to the opening.
PGT WinGuard impact-rated units are designed for high-wind and wind-borne debris zones, and we confirm the exact product approvals against Marin County’s current building code during permitting. Wildfire requirements involve additional factors like ember-resistant venting and defensible space, so we’ll review the whole wall assembly, not just the window spec. Call (866) 253-5808 and we’ll walk you through what your specific house needs.
Tiburon’s fog belt means the exterior side of your PGT frames stays damp for months at a time, so flashing has to direct water out and down without relying on caulk as the primary barrier. Inland cities dry out between storms and get away with less detailing. On the bay-facing side, we always rebuild with sill pans and a proper WRB tie-in, because that’s the only assembly that survives here long term.
