PGT Construction in Tiburon, CA | Framework Contractors
We provide independent PGT window and door installation, repair, and retrofit service across Tiburon’s hillside lots and bayside exposures. What makes our PGT work different here: we treat every window or door replacement as a slope-and-drainage job first, because on most Tiburon parcels, the downhill wall is doing structural work that a glazing-only crew never sees. Led by Noel Carbajal, our crews install and service WinGuard impact lines, Premium Vinyl, and Aluminum Series units with OEM parts and honest repair-versus-replace guidance. Call (844) 681-3590 for a free estimate.
Why Tiburon Residents Choose Us for PGT Service
Noel Carbajal has spent close to three decades framing, flashing, and finishing windows and doors across hillside and coastal California. He grew up patching stucco and reroofing porches with his uncle, then learned structural drawings and building science at Santiago Canyon College. That background matters in Tiburon, where a PGT slider on a downhill wall is rarely just a slider. We’re an independent PGT service provider, not an authorized dealer or manufacturer affiliate, so our recommendation is based on what your rough opening, flashing, and drainage are actually doing, not on moving a product line. We also offer our General Contractor in Tiburon expertise for complex projects. Homeowners here call us because we know which WinGuard units hold up against salt air on the bayside and which older aluminum frames are worth saving versus replacing.
We keep OEM PGT sashes, rollers, locks, and insulated glass units on hand for the model lines most common in Marin, including experience with PGT in Chinatown and similar coastal properties, which shortens turnaround when we can repair rather than replace. And when a full unit swap is the right call, we coordinate the shoring and drainage work first, so the new window doesn’t inherit the old window’s problems.

Common PGT Construction Problems We Solve in Tiburon
- Fogged insulated glass from seal failure: Bayside fog and salt air work on IG seals year-round, and accelerated UV on south-facing hillside exposures doesn’t help. We replace failed PGT glass units with OEM-matched panes, and if the frame is still sound, that’s often a one-visit fix.
- Water intrusion at sills and jambs on downhill walls: On homes where the downhill foundation wall is also the retaining structure, winter rain concentrates drainage right at the wall base and hydrostatic pressure builds behind it. We see PGT units that were flashed for a standard wall but not for a wall holding back a slope. We correct the drainage plane and then reset or replace the unit.
- Racking and binding in large WinGuard sliders and casements: Tiburon soils move seasonally as the water table rises in winter and drops in summer. Big PGT sliders on hillside elevations take that movement and bind. Shim-and-level isn’t enough; if the frame has twisted, we give you a straight answer about whether replacement with a sturdier WinGuard Aluminum unit is the better long-term move.
- Corroded hinges, rollers, and fasteners on older aluminum units: Marine air does slow damage to exposed hardware, and brushed-finish pitting is common within a decade of bayside installation. We replace hardware with PGT OEM parts rather than universal aftermarket, because the tolerances on WinGuard multipoint locks are too tight for generic substitutes.
- Ember-caused damage to frames and weatherstripping near the wildland edge: Homes on the ridges above downtown sit in the wildland urban interface, and wind-driven embers find their way into worn weatherstripping and frame gaps. We retrofit fire-resistant gasketing and inspect joints when we’re already on-site for a replacement.
PGT Service in Tiburon: What Local Conditions Mean for Your Equipment
On the hillside streets above downtown Tiburon, the downhill foundation wall often doubles as the retaining structure holding the road or the neighbor’s slope. That’s not a detail, it’s the whole job. We replaced a set of PGT WinGuard sliders on one of those streets that had racked and leaked at the sill for years. The glass was fine, the frame wasn’t, and the real problem was that the downhill wall was carrying the neighbor’s slope and pushing water into the rough opening every winter. We coordinated shoring and cut in a new drainage plane before setting the new units. The binding stopped and the water intrusion stopped. No glazing-only crew would have touched that wall, and a flat-lot window contractor from Corte Madera or San Rafael wouldn’t have looked twice at it. For specialized hillside work, you need a Sausalito PGT service with similar terrain experience. If your PGT windows or doors are failing on a downhill-facing elevation, the fix probably starts behind the frame, not in it.
PGT Models & Products We Service in Tiburon
We service the four PGT lines most common across Marin residential work: WinGuard Aluminum Impact Series, WinGuard Vinyl Impact Series, Premium Vinyl Series, and the Aluminum Series. For repairs we use OEM PGT sashes, rollers, locks, and glass units to preserve fit and finish. We don’t pad a job with aftermarket parts that almost work. On replacement work, we carry enough stock of common WinGuard sizes to pull and prep most Tiburon jobs without waiting on a long-lead factory order, though custom sizes still come direct from PGT. If you’re weighing a repair against a replacement, we make that call based on the condition of the rough opening and the drainage detailing behind the frame, not just the condition of the glass. Our crews also handle full PGT sales & service for homeowners who want one accountable team from tear-out to trim.

AfterPGT Service Pricing in Tiburon
Here’s what we quote for the PGT work we do most in Tiburon. These ranges reflect the added complexity of hillside access, shoring, and drainage correction that most flat-lot towns never see.
| Service | Typical Range in Tiburon |
|---|---|

| Impact Window Installation | $8,000 – $25,000 |
| Home Addition | $45,000 – $130,000 |
Your final number depends on how many units, which PGT line, whether the wall needs drainage plane correction, and how much material has to be walked or staged on a narrow fire road. Every free estimate includes a written line-item break down of material, labor, and any slope-related work. No change orders built into the fine print. Call (844) 681-3590 and we’ll walk you through the numbers for your specific elevation and exposure.

FAQs – PGT Construction in Tiburon
Hillside lots concentrate water against the downhill wall, and Tiburon’s winter rains plus seasonal soil movement create hydrostatic pressure and frame racking that flat lots never experience. The window or door isn’t failing because it’s a bad unit; it’s failing because water and movement are working on the frame 24/7. That’s why we always inspect the drainage plane and rough opening before recommending a repair or replacement. Call (844) 681-3590 to schedule a free on-site look.
Usually yes, on a residential window or door swap. We sequence the work so the existing wall stays supported while the new unit goes in, and we add drainage correction at the rough opening rather than rebuilding the foundation. If we find that the wall itself is failing, we’ll tell you before we quote the window work, not after. Your estimate is free, and it won’t become a foundation bid unless the opening actually needs it.
Tiburon’s ridge homes sit in a wildland fire zone, and the details that matter are the frame-to-wall joints and weatherstripping. We inspect and often replace worn gasketing and sealants when we install or repair PGT units, using fire-resistant materials rated for exterior exposure. We also check that ember screens and frame joints aren’t leaving gaps at the sill or jamb. Give us a call at (844) 681-3590 and we’ll review your exterior openings as part of the free estimate.
Tiburon’s fire roads are tight, and some parcels have no pull-up access at all. We walk small units and hand-carry larger panels with a two-person crew, and we stage materials in sequence so nothing sits in the road longer than it has to. We don’t bring a crane unless the job genuinely needs one, and we’ll tell you if parking or staging restrictions on your road will affect the schedule before we start.
Fogging means the IG seal has failed, and sticking usually means the frame or track has shifted. You’re looking at a glass unit replacement and possibly a roller and track correction. In Tiburon, we’d also check for water intrusion at the sill, because the two problems often show up together on downhill-facing walls. Call (844) 681-3590 for a free repair-versus-replace assessment, and we’ll tell you which path makes sense for your door.
