Therma-Tru Construction in Tiburon, CA | Framework Contractors
We’re an independent Tiburon General Contractor and Therma-Tru construction specialist working Tiburon’s hillside parcels, where fiberglass and steel entry systems get fitted into rough openings framed decades before modern door tolerances existed. What sets our Therma-Tru work here apart is that we understand the slope: on many Tiburon lots, a sticking door or rotting sill traces back to the downhill foundation wall, not the door itself. Call (844) 681-3590 for a free estimate on Therma-Tru service, and we’ll survey the wall, the drainage, and the opening before anyone touches a screw.
Why Tiburon Residents Choose Us for Therma-Tru Service
Framework Contractors carries Therma-Tru expertise across every major model line, and we’ve applied our Sausalito Therma-Tru service experience on enough Tiburon hillside entries to know that a door is only as good as the frame it hangs in and the wall that holds the frame. We use Therma-Tru OEM sills, sweeps, and weatherstrip where the door is sound, and quality aftermarket hardware where OEM is back-ordered. But we’re not shy about saying when a Tiburon door has absorbed too much water at the sill to patch meaningfully. As Noel Carbajal, our owner, puts it: “Build it right the first time – the second time costs twice as much and nobody’s happy.” That’s not a tagline, it’s how we bid. One contractor. Every system. From the roof down to the foundation, including the entry door that takes the brunt of Marin County weather.

Common Therma-Tru Construction Problems We Solve in Tiburon
- Sill and jamb rot on downhill-facing entries. Bayside fog keeps the threshold wet for months, and on sloped landings the door is the low point. Water sits, wicks, and works into the jamb. We re-flash, replace the sill with OEM, and re-set the frame to drain.
- Fiberglass skin chalking and blistering on west- and bay-facing exposures. Salt fog plus winter rain that never fully dries breaks down the finish coat faster than inland. We inspect for skin integrity and tell you honestly whether it’s a refinish or a re-slab.
- Weatherstrip and sweep failures that let wind-driven ridge rain track under the slab. The water ends up in the subfloor, and by then the door isn’t the only problem. We replace with OEM sweeps and re-align the threshold to shed water away from the opening.
- Frame racking and dragging slabs from seasonal foundation movement. In Tiburon, many homes sit on downhill foundation walls that also act as retaining walls. When the wall breathes with the winter water table, the door binds. We survey first, then shim and re-set to a true plumb line.
- Patio and sliding door systems that seize on sloped tracks. Tiburon decks settle, tracks run out of level, and doors grind. We re-bed tracks, adjust rollers, and replace sweeps so the door actually slides.
Therma-Tru Service in Tiburon: What Local Conditions Mean for Your Equipment
The Tiburon condition that shapes more of our Therma-Tru work than anything else is this: on the hillside streets above downtown, many homes are built so the downhill foundation wall doubles as the retaining structure holding the road or a neighbor’s slope, similar to what we see providing Marin City Therma-Tru service. When a Therma-Tru entry door starts dragging or the sill rots, the real cause is often seasonal movement in that wall, not the door itself. The winter water table turns any excavation into a dewatering and shoring problem before the first screw goes in. We’ve seen Fiber-Classic doors that wouldn’t latch in February and swung fine by July, and the fix wasn’t the latch but the plumb line of a jamb sitting on a moving wall. We survey the wall and drainage before we set a new frame, because on these streets, you’re not replacing a door, you’re re-anchoring an opening to a slope that’s been working against it for fifty years. That’s the part no flatland page about Tiburon can tell you, and no generic door page would think to check.
One job sticks with us. On a hillside street above downtown, we were called out for a Fiber-Classic entry door that had started dragging and wouldn’t latch through the wet months. Pulling the interior trim showed the downhill jamb sitting on a foundation wall that was also holding the slope above the road, with the winter water table pushing moisture up through the sill. We dewatered and re-flashed the threshold, shimmed and re-set the frame to a new plumb line, and hung a fresh Smooth-Star slab with an OEM sweep so the door finally sealed against the driving fog rain. Built to spec, not to shortcut.
Therma-Tru Models & Products We Service in Tiburon
We work across the Therma-Tru line: Fiber-Classic fiberglass entry doors, Smooth-Star smooth fiberglass exterior doors, the Pulse entry and patio door series, and Therma-Tru’s patio and sliding glass door systems, including Therma-Tru in Chinatown and throughout the Bay Area. For Tiburon turnaround, we stock OEM-compatible sills, sweeps, and weatherstrip for the models most common on these hills, and we know which aftermarket hardware holds up in salt fog. We’re not manufacturer-authorized, and we don’t claim to be. We’re independent, which means our recommendation is about the door in front of us, not a quota. Your materials, our craftsmanship. When a home addition in Tiburon calls for matching a new Therma-Tru entry to an existing one, we re-spec openings and hardware so the new door doesn’t look like an afterthought.

FAQs – Therma-Tru Construction in Tiburon
In most Tiburon hillside homes, the winter water table swells the soil behind the downhill foundation wall, which is often also the retaining wall. The wall moves a fraction of an inch, and because your door jamb is anchored to that same wall, the slab starts to drag. It’s not the door; it’s the wall breathing. We fix it by re-shimming the frame to a new plumb line and re-flashing the threshold so moisture stops wicking up. Call (844) 681-3590 and we’ll confirm what’s actually moving before quoting a repair.
Often, yes. When the downhill foundation wall carries the road or a neighbor’s slope and we discover rot or movement, the scope can expand into drainage correction, retaining-wall repair, and structural review, which pulls in grading and building plan review. We pull the permits, and we pass the inspections. Call (844) 681-3590 for a scope review.
Smooth-Star fiberglass slabs with a proper OEM sweep and a flashed, drained sill hold up better than wood-frame entries in constant fog exposure. The fiberglass skin won’t swell, and with the threshold re-flashed the way we do it on these slopes, water sheds away instead of sitting. Fiber-Classic is fine too if the finish is maintained on west- and bay-facing exposures. Call (844) 681-3590 and we’ll recommend based on your exact exposure.
Yes. We match the model line, slab profile, hardware finish, and glass pattern to the existing entry, then re-spec the rough opening for the addition’s framing. The goal is a new door that looks like it was always there, not a near-match. Call (844) 681-3590 with the existing door’s brand and we’ll work up the match.
West- and bay-facing Tiburon doors take late-afternoon sun, salt fog, and winter rain that never fully dries, and the combination breaks down the finish coat years earlier than the same door would inland. We check whether the skin itself has blistered or chalked, and we recommend a refinish or a re-slab accordingly. Call (844) 681-3590 and we’ll tell you if it’s saveable or a replacement.
