Therma-Tru Construction in Lompico, CA | Daly City Construction
We provide independent Therma-Tru sales & service across Lompico, CA, for entry doors, patio sliders, and the window systems that hold up to redwood-belt humidity and steep terrain. What makes our Therma-Tru work here different is that we plan around Lompico’s actual job-site conditions from day one: unpaved private drives that wash out, tight canyon lots, and pier-and-grade foundations that move. Call (866) 505-5254 to schedule a free estimate. We’re Daly City Construction, led by Noel Cabrera, and we’ve been running Therma-Tru installs and repairs in the Santa Cruz Mountains long enough to know the difference between a door that needs a threshold rebuild and one that needs a full frame reset.
Why Lompico Residents Choose Us for Therma-Tru Service
Most contractors can hang a door. Fewer can tell you why a Fiber-Classic slab is swelling at the bottom rail on a 1960s Lompico cabin, or why a Smooth-Star steel door is rusting at the lock rail after a single wet winter. We can. Noel Cabrera grew up in Daly City’s Westlake district, watching his uncle re-frame a garage, and he trained in construction technology at City College of San Francisco before putting in years on residential and light commercial jobs across San Mateo and San Francisco counties. That background taught us to look at the whole opening: the flashing, the sill pan, the subfloor, the way water actually moves against a west-facing wall in a canyon that gets heavy winter rain. Lompico homes have their own set of rules, and as a Lompico General Contractor, we’ve learned them the only way you can: by seeing what fails here.
We source OEM Therma-Tru sills, sweeps, astragals, and multipoint hardware for proper fit, and we use quality aftermarket weatherstrip and glass units where they meet the same performance standard. Repair is usually the right call unless the slab or frame has structural rot or repeated water intrusion. Tell me what the house needs, not what you think it needs, then we’ll figure out the right fix.

Common Therma-Tru Construction Problems We Solve in Lompico
- Fiber-Classic slab delamination at the bottom rail. Lompico’s crawl-space moisture and redwood-canopy humidity trap water behind poorly flashed thresholds. We see Fiber-Classic doors on older cabins where the bottom rail has swollen, split, or started to delaminate. We rebuild the threshold with a proper sill pan, address the crawl-space venting or drainage that caused the moisture, and reset the slab plumb.
- Smooth-Star steel door rust at the lock rail and bottom edge. Winter rain driven against west-facing walls finds failed weatherstripping and sill pans. We replace the weatherstripping, address the sill pan, and match the finish on the steel skin where we can. If the rust has compromised the steel, we’ll say so plainly and quote a replacement.
- Classic-Craft entry system racking out of square. Lompico’s older vacation homes sit on pier-and-grade foundations that shift with winter saturation and dry summer months. Deadbolt misalignment and air infiltration are the usual symptoms. We reset the frame, adjust the multipoint hardware, and recommend foundation or drainage work if the movement is ongoing.
- Pulse patio door rollers and tracks clogged with redwood duff. Long private drives throw grit and debris into door tracks, and storm season makes it worse. We clean and replace rollers, straighten or replace tracks, and adjust the sliding panel so it moves without shoulder pressure.
- Threshold rot from repeated water intrusion. On Lompico’s small, irregular lots, drainage is often under-served. When water sits at an entry threshold, the rot migrates into the subfloor. We cut out the rot, rebuild the threshold assembly, and tie in drainage so the water doesn’t return.
Therma-Tru Service in Lompico: What Local Conditions Mean for Your Equipment
Here’s the thing about Lompico that nobody from outside the canyon really understands until they’ve worked here. Nearly every home sits on a steep, wooded lot served by a private road or a long driveway, and in winter those unpaved drives wash out. Concrete trucks and material deliveries often can’t reach the build site, so crews routinely schedule pumper trucks, mini-mixers, or conveyors. For Therma-Tru in Mount Hermon and nearby canyon work, that means door and window deliveries regularly get hand-carried or shuttled from the Highway 9 turnoff, and we stage and protect slabs on site longer than we would in a flat-lot town like Boulder Creek. A Fiber-Classic door slab weighs enough that hand-carrying it up a washed-out drive is a two-person job with a panel cart. We plan for that. We also plan for the humidity that sits under the redwood canopy, because a door that looks fine in a showroom can start swelling within a season if the threshold isn’t flashed for Lompico’s soil moisture. The access and the moisture aren’t separate problems; they’re the same problem wearing two different hats.
Therma-Tru Models & Products We Service in Lompico
We work on the Therma-Tru lines you’re most likely to find on Lompico cabins and expanded vacation homes: Fiber-Classic, Smooth-Star, Classic-Craft, and Pulse. Each one fails differently here. Fiber-Classic is a fiberglass slab that’s good for humid climates when the threshold is right, but it punishes bad flashing. Smooth-Star is a steel-skinned line that needs its weatherstripping maintained, especially on west-facing walls. Classic-Craft is a higher-end entry system with multipoint locking hardware that doesn’t tolerate foundation movement. Pulse is the patio door line, and its roller tracks collect everything the redwoods drop on them. We stock common OEM sills, sweeps, and astragals for faster turnaround in Lompico and Therma-Tru repair in Felton, and we can source the rest quickly.

FAQs – Therma-Tru Construction in Lompico
Yes, if the threshold is flashed correctly and the crawl-space moisture is managed. Fiber-Classic slabs don’t rot the way wood does, but they can delaminate at the bottom rail when water sits against them season after season. On Lompico cabins with high crawl-space moisture, we typically rebuild the threshold with a proper sill pan and address the crawl-space venting before resetting the slab. Call (866) 505-5254 for an exact assessment.
It changes how we stage and transport materials. On unpaved drives that wash out in winter, we hand-carry or shuttle slabs from the Highway 9 turnoff, and we protect them on site longer than we would on a flat lot. That staging is built into our Lompico estimates, so you won’t get a surprise delivery charge after the fact.
They can, especially at the lock rail and bottom edge where water gets behind failed weatherstripping or a cracked sill pan. The fix is usually new weatherstripping, a rebuilt sill pan, and touch-up on the steel skin where rust has started. If the rust has gone through the skin, replacement is the honest call. Call (866) 505-5254 and we’ll tell you which one applies to your door.
Redwood duff, grit from private drives, and wet-season debris collect in the roller tracks and corrode the rollers. We clean the tracks, replace rollers, and straighten or replace tracks as needed. On steep lots, we also check that the frame hasn’t shifted with the slope, because a racked frame will make even new rollers bind.
It’s a solid piece of the equation. Fiberglass and steel doors are non-combustible in a way wood and hollow-core doors aren’t, and ember-resistant weatherstripping can close the gaps where embers find their way in. We’ve replaced failing entry doors on Lompico cabins with Fiber-Classic and Smooth-Star units specifically for that reason, paired with ember-resistant vents where the crawl space allows. Call (866) 505-5254 to talk through what makes sense for your house.
