Therma-Tru Construction in San Carlos, CA | Framework Contractors
We’re Framework Contractors, a San Carlos General Contractor and independent construction crew that installs and services Therma-Tru doors and windows across the area. The thing that separates our Therma-Tru work here from everywhere else: we understand what these fiberglass and steel systems actually do on a built-out Peninsula lot, where every opening is framed inside an existing wall, often on a slope, and always under a permit inspector’s eye. We’re not authorized or sponsored by Therma-Tru, we just know their product lines cold. Call (844) 681-3590 to schedule a free estimate.
Why San Carlos Residents Choose Us for Therma-Tru Service
Therma-Tru specialists know the brand builds a solid door. But a door is only as good as the opening it’s set into, and in San Carlos the openings are rarely square. Most of the homes here went up in the 1940s through 1960s, framed with the materials and tolerances of that era. Add decades of clay soil movement under pier-and-post foundations and you get walls that have drifted. Noel Carbajal, our owner, has spent the better part of three decades working on exactly these houses; he grew up patching stucco with his uncle and later learned structural drawings at Santiago Canyon College, so when a Therma-Tru slab binds at the latch, he knows whether the fix is the door or the wall. We carry the OEM thresholds, weatherstrip, and hardware that match Therma-Tru factory tolerances, because that’s what actually keeps Peninsula rain out. And we show up with a plan. Build it right the first time – the second time costs twice as much and nobody’s happy.

Common Therma-Tru Construction Problems We Solve in San Carlos
- Chalking and fading on west-facing fiberglass slabs. San Carlos gets long, dry summers with unshaded afternoon sun hitting front entries hard. Therma-Tru Fiber-Classic and Smooth-Star finishes hold up better than most, but we regularly see factory finish breaking down around the stile edges first, years before the door itself is worn out. We refinish or replace the slab and address the sun exposure where we can with proper sealing.
- Threshold and sill rot on slab-on-grade ranch entries. Winter rain drives sideways against older San Carlos ranch homes where the door sits only a few inches above the stoop and drainage was never detailed. Water wicks into the sub-sill, rots it, and the door starts to leak at the threshold. We rebuild the threshold with proper flashing tied to drainage, not just a caulk bead.
- Failed weatherstrip and sweeps on decade-old units. The 1950s and 60s tract homes around San Carlos often have original or builder-grade Therma-Tru doors with tired weatherstrip. When the sweep goes, water tracks under the door and swells the sub-sill. We replace with OEM Therma-Tru weatherstrip matched to the door’s profile.
- Binding doors in out-of-plumb openings. Knob-and-tube-era walls were rarely framed square, and on San Carlos hillside lots the foundation has often moved since. A new Therma-Tru slab binds at the head or latch because the rough opening isn’t true. We reframe and re-shim the opening before hanging the door, because forcing a square door into a crooked wall never ends well.
- Rotted jambsets from years of deferred maintenance. We see this on homes where the original threshold failed and nobody caught it for two wet seasons. By the time we’re called, the jambset and sub-sill are rotted through. We tell owners honestly when a patch won’t hold and rebuild the frame instead.
Therma-Tru Service in San Carlos: What Local Conditions Mean for Your Equipment
San Carlos is built out. There’s no greenfield left, which means nearly every Therma-Tru door and window we install here lands inside a phased remodel, an addition, or a scrape-and-rebuild on a 5,000 to 7,000 square foot lot. That shapes the work. Our crew stages doors and frames around an occupied house, runs material through narrow side-yard access, and coordinates with slope-driven foundation work on the hillside parcels above the flats. On a recent job above downtown, near the older blocks off Laurel Street, we opened a wall for an addition and found the existing Therma-Tru Fiber-Classic entry had been set into a rough opening that had shifted on the slope, with a rotted sub-sill and failing sweep letting winter rain track in — a typical case for Therma-Tru service in Redwood City and nearby hillside areas. We reframed and re-shimmed the opening, rebuilt the threshold with proper flashing tied to the new drainage, hung a factory-finish Smooth-Star slab with OEM weatherstrip, and the door has sealed cleanly through two wet seasons since. That’s what local conditions mean: not just swapping a door, but making it work inside a house that’s moving, on a lot that drains toward the foundation, while the family still lives there.
Therma-Tru Models & Products We Service in San Carlos
We work on the full Therma-Tru residential lineup: Fiber-Classic fiberglass entry doors, Smooth-Star fiberglass doors, the Classic-Craft collection, and patio and hinged exterior door systems with sidelites. For repairs, we use Therma-Tru OEM replacement slabs, thresholds, weatherstrip, and hardware wherever the frame is sound, because the factory-matched sill and sweep are what actually keep water out. When a jambset or sub-sill is rotted through, we rebuild the frame rather than patching a door that will fail again next wet season. We keep common Therma-Tru weatherstrip profiles and threshold components stocked for fast turnaround across San Carlos, so a door service call doesn’t turn into a two-week wait on a shipped part.

AfterTherma-Tru Service Pricing in San Carlos
Therma-Tru work in San Carlos almost never prices as a standalone door swap.

Here’s what the broader work typically runs:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Home Addition | $45,000 – $130,000 |
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
Your free estimate includes a look at the whole opening, the drainage path, and any adjacent framing issues. We give written line-item pricing. Call (844) 681-3590 and we’ll walk the site with you.

FAQs – Therma-Tru Construction in San Carlos
Can you replace a Therma-Tru entry door during a phased remodel while we’re still living in the house?
Yes. That’s how most of our Emerald Lake Hills Therma-Tru service and San Carlos work happens. We stage the old door until the new slab and frame are ready, keep the opening weather-tight overnight, and schedule around your occupancy. On hillside and narrow-lot jobs we often have to sequence the door replacement with foundation and drainage work, and we build that into the schedule from day one. Call (844) 681-3590 and we’ll lay out a phased plan that keeps the house liveable.
Our 1960s San Carlos ranch door drags at the top corner – is that the door or the opening?
In a 1960s San Carlos ranch, it’s usually the opening. Those original walls were rarely square, and after sixty years of clay soil movement under a pier-and-post foundation, the framing has drifted. A new Therma-Tru slab is square, so it binds at the head or latch if the rough opening isn’t true. We’ll confirm with a level and a string line, then reframe and re-shim the opening before hanging the door. That’s the only fix that lasts. For an on-site assessment, call (844) 681-3590.
Does adding a new exterior door or patio door as part of an addition need a San Carlos permit?
Yes. San Carlos is permit-heavy, and any new or enlarged exterior opening, including a Therma-Tru patio door added as part of an addition, requires plan review and inspection. We pull the permits, schedule the inspections, and handle the paperwork. It’s standard for every job we run in San Carlos. Call (844) 681-3590 and we’ll tell you what your specific project needs.
How do winter rains and summer sun affect a Therma-Tru door on an unshaded San Carlos frontage?
The sun does the cosmetic damage: west-facing fiberglass slabs chalk and fade at the stile edges after years of unshaded afternoon exposure. The rain does the structural damage: winter storms drive water against slab-on-grade entries, and if the threshold or sweep has failed, the sub-sill rots. We address both in San Carlos, refinishing or replacing faded slabs and rebuilding thresholds with proper flashing and drainage. Call (844) 681-3590 for a free estimate on either issue.
Will a Therma-Tru door replacement pair with a roof replacement on the same remodel?
Yes, and it often should. On San Carlos remodels we frequently run door, window, and roof work under one contract. Roof replacement fixes the water that was getting to the door in the first place, and the door replacement fixes the entry that the roof was dumping water onto. One crew, one schedule, one set of inspections. Call (844) 681-3590 and we’ll walk the whole exterior with you, from the roof down.
