Therma-Tru Construction in Tiburon, CA | San Bruno Construction
We provide independent Therma-Tru door installation, repair, and replacement across Tiburon, and the one thing that sets our work apart here is that we plan for the hillside before we ever unload a slab. On steep Tiburon driveways, getting a full door unit to the opening is often harder than hanging it. Call (866) 472-1908 for a free estimate from a contractor who has carried Therma-Tru doors up Marin hillsides more times than we can count.
Why Tiburon Residents Choose Us for Therma-Tru Service
Tiburon homes aren’t tract houses. They’re mid-century custom builds on stilt-and-pier foundations, cantilevered decks, and slopes that move a little every wet season. That changes how doors fit, seal, and hold up. We’ve installed and serviced Therma-Tru Fiber-Classic, Smooth-Star, and Classic-Craft doors across Marin’s hillside homes for years, including Sausalito Therma-Tru service nearby, so we know how their fiberglass systems behave under real coastal-wet, dry-summer cycling, not just what the catalog says.
We’re an independent contractor. We are not authorized, sponsored, or endorsed by Therma-Tru, and we’ll tell you that straight. What we do bring is our Home Remodeling in Tiburon range to handle everything around the door: the re-flashing, the siding repair, the threshold rebuild, the stucco patch. Noel Carvalho, our owner, trained in construction technology at Skyline College and has run residential projects across San Mateo County for over two decades. He’s the one who’ll look at a racked frame on a Tiburon hillside and tell you whether to square it or replace the unit. Good construction doesn’t announce itself; it just works, year after year.

Common Therma-Tru Construction Problems We Solve in Tiburon
- Chalked and faded fiberglass slabs on west-facing entries. Tiburon gets intense afternoon sun off the bay, and that exposure bakes the factory finish on Fiber-Classic and Smooth-Star doors faster than almost anywhere else in Marin. Once the topcoat fails, the substrate starts wicking moisture, and you’re not refinishing, you’re replacing.
- Swollen, delaminating door edges from wind-driven winter rain. Marin’s wet winters push rain sideways into entry thresholds. If the drip edge wasn’t re-flashed properly, water wicks past the sill and into wood-veneer and stainable door edges. We see this constantly on older Tiburon homes.
- Doors out of square on stilt-and-pier foundations. Seasonal slope movement racks door frames. The slab drags, weatherstripping gaps open, and multipoint hardware binds. This is a structural issue as much as a door issue, and we approach it that way.
- Rotted sub-sills and threshold pans under glass-door units. Cantilevered decks on Tiburon hillsides settle, dry rot spreads from old deck framing, and the soft wood under the door unit goes with it. A new slab won’t fix a rotten sub-sill.
- Marine-air corrosion on hinges and hardware. Salt-laden air off Richardson Bay works into unprotected metal parts. Hinges seize, multipoint mechanisms stiffen, and lock cylinders corrode. We spec marine-grade replacements where the exposure calls for it.
Therma-Tru Service in Tiburon: What Local Conditions Mean for Your Equipment
On Tiburon’s hillside streets, the door is only half the job. Narrow, steep driveways mean entry doors are often hand-carried up in pieces or hoisted, and any re-flash and siding repair around the opening has to be planned before the slab ever leaves the truck. You can’t just back a van up to the front step on a street like Sugarloaf Drive or Paradise Drive. That access constraint changes sequencing: we stage materials at the top of the drive, protect the opening, and coordinate every trade so the job doesn’t stall halfway through. In flatland Marin, a door swap is a two-hour job. In Tiburon, it’s a logistics exercise with a door attached. That’s not a complaint; it’s the reality that keeps quotes from blowing up mid-project.
We’ve lived it. On a steep Tiburon street, we replaced a weathered Fiber-Classic entry on a mid-century pier home whose soft sub-sill had let winter rain wick into the frame, so the slab dragged and the weatherstripping gapped. We re-flashed the threshold, set a new OEM fiberglass slab and sill in the squared opening, and hauled the old unit down the narrow driveway by hand because no truck could reach the door.
Therma-Tru Models & Products We Service in Tiburon
We work on the full Therma-Tru line that shows up in Tiburon homes, and Therma-Tru in Chinatown nearby: Fiber-Classic, Smooth-Star, Classic-Craft entry doors, Therma-Tru door slabs, and units with Therma-Tru multipoint and hinged patio-door hardware. Our parts approach is simple. Where the frame and glass unit are sound, we use Therma-Tru OEM slabs, sills, sweeps, and hinges. Where aftermarket parts make sense and match the door’s spec, we’ll use quality weatherstripping, thresholds, and multipoint hardware. If the slab is delaminated or the frame is racked, honest replacement of the whole door unit usually beats chasing a patch on a hillside entry that takes full weather all year.

AfterTherma-Tru Service Pricing in Tiburon
Entry door work in Tiburon generally falls within a few established ranges: door slab replacement runs between $800 and $3,000 depending on model and finish; full entry door unit replacement typically lands between $1,500 and $5,000; and if the job expands into surrounding framing, re-flashing, or siding repair, you’re looking at $4,000 to $10,000 when it’s part of a larger entry rebuild. For homeowners pairing a Therma-Tru entry replacement with broader improvements, roof repair runs $400 to $1,800, window replacement $4,500 to $15,000, and impact window installation $8,000 to $25,000.
The hillside itself drives the final number: access, shoring, and how much surrounding framing needs attention. We don’t give vague quotes. Every estimate is a written, line-item breakdown so you know exactly where the money goes. Call (866) 472-1908 and we’ll walk the site and get you the real number.

FAQs – Therma-Tru Construction in Tiburon
Sometimes, if the topcoat has only begun to chalk and the substrate is still sealed, a professional re-finish will buy you a few more years. But on a west-facing Tiburon entry that’s been baking for a decade, the fiberglass is usually compromised past the point where re-finishing makes sense. Call (866) 472-1908 and we’ll tell you which side of that line your door is on; the estimate is free.
Because the foundation moves. Stilt-and-pier construction flexes with seasonal slope movement, and over decades the door frame shifts enough that the slab drags and the weatherstripping gaps. You can re-hang the slab, but if the piers are the problem, the fix is structural before it’s cosmetic.
Generally, a like-for-like door replacement in an existing opening is exempt, but once you modify framing, widen the opening, or trigger Tiburon’s design review, you’re in permit territory. We’ll tell you upfront what the Town of Tiburon will require for your specific site and pull permits when they’re needed.
It corrodes it. Hinges seize, multipoint mechanisms stiffen, and lock cylinders pit. We spec hardware rated for coastal exposure on every Tiburon install, because standard residential hardware fails years early in that salt air. Call (866) 472-1908 for an exact quote on a coastal-spec Therma-Tru unit.
Yes, and we do it regularly. We hand-carry the unit in pieces, hoist where needed, and stage everything so the opening is never left exposed. It’s slower, and the labor shows up in the quote, but the job gets done without a crane bill and without tearing up your landscaping.
