Therma-Tru Construction in Pacifica, CA | San Bruno Construction
We provide independent Therma-Tru door installation and repair across Pacifica, from ocean-facing bluffs to the sheltered streets east of Highway 1, and also offer Therma-Tru repair in San Bruno. What makes our Therma-Tru work here different is simple: we spec and seal every door based on which side of the fog belt your house sits on, because a west-side door facing the Pacific fails differently than an inland one a few blocks away. Call (866) 472-1908 for a free estimate on repair or replacement.
Why Pacifica Residents Choose Us for Therma-Tru Service
Our crew has pulled apart enough Therma-Tru doors in Pacifica to know exactly where they fail in this climate. We’re an independent contractor, not authorized by Therma-Tru, but that independence means we tell you straight whether a door is worth saving or past the point of repair. Noel Carvalho, who runs San Bruno Construction, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before a single tool comes out of the truck. That same discipline applies to door work: we diagnose the jamb, the sill, the weatherstripping, and the slab before we quote a number. For full Therma-Tru sales & service, we coordinate everything from material selection to final trim, and we use OEM parts when the existing door is sound enough to justify the repair.

Common Therma-Tru Construction Problems We Solve in Pacifica
- Hairline cracks and chalky oxidation on fiberglass door skins. West-facing Fiber-Classic and Smooth-Star doors take the brunt of Pacifica’s salt-laden marine layer. The factory finish breaks down faster here than inland, and once the topcoat goes chalky, moisture gets into the skin and starts hairline cracking along the panel edges. We re-seal before it spreads.
- Rust at the bottom rail and hinge stiles on steel Therma-Tru doors. Older mid-century homes in Pacifica often still have original steel entry doors. Winter rain and constant coastal damp penetrate compromised paint or torn weatherstripping, and rust starts at the bottom corners first. If the rust is surface-level, we can treat and repaint; if the door skin is perforated, replacement is the honest call.
- Swelling and delamination at the lock rail and bottom sweep. Wood-edge and composite Therma-Tru slabs absorb moisture during wet-season cycles, especially on ocean-facing elevations where the damp never fully dries. The door starts binding at the latch, then the edge begins to delaminate. We see this constantly on the west side of Pacifica.
- Compressed and torn weatherstripping on patio and storm door systems. Wind-driven rain off the Pacific forces water past factory sweeps that were never meant for Pacifica’s exposure. Once the sweep tears, water tracks inside and rots the frame from the bottom up. We replace with OEM sweeps and add a secondary storm door buffer where the exposure calls for it.
- Sill rot under Therma-Tru entry doors. Pacifica’s winter rain pools at door thresholds on sloped lots, and once the sill flashing fails, the subfloor under the door starts to rot. By the time a homeowner notices the door rocking or the threshold feeling soft, the sill often needs full replacement, not just a sweep swap.
Therma-Tru Service in Pacifica: What Local Conditions Mean for Your Equipment
Pacifica is split by Highway 1, and that highway line is the difference between a Therma-Tru door lasting fifteen years or needing serious attention in half that time. Houses on the west side sit in the fog belt, where the marine layer lingers and salt air never lets wood, composite, or even factory-finished fiberglass fully dry. Locals know this as fog-belt rot: deck joists and rim boards replaced every couple decades, exterior paint failing early, and door frames swelling shut every winter. East of the highway, a few blocks inland, the same-model Therma-Tru door lasts far longer because the air actually dries. So when we service a home off Crespi Drive or along the bluffs near Rockaway Beach, we spec door hardware, weatherstripping, and sealants differently than we would for a house up toward San Pedro Valley or Linda Mar, or for Therma-Tru in Colma. The door model might be identical. The installation approach is not.
Therma-Tru Models & Products We Service in Pacifica
We work on the full Therma-Tru residential lineup: Fiber-Classic entry doors, Smooth-Star fiberglass doors, Classic-Craft door series, and Therma-Tru patio and storm door systems. For repair work, we use OEM Therma-Tru parts (sills, sweeps, weatherstripping, hinges) whenever the slab and frame are still sound, because fit and finish on these systems depend on factory tolerances. When rot or delamination has already compromised the jamb or slab, we’ll tell you that a new Therma-Tru door (or a quality alternative from our broader door lineup) is the better investment. We stock the most common OEM sweeps and weatherstripping for fast turnaround on Pacifica service calls.

AfterTherma-Tru Service Pricing in Pacifica
Pricing depends on whether we’re repairing an existing door, replacing a slab, or integrating new door and window systems into a larger project. Here’s what Therma-Tru work typically runs in the Pacifica market:
| Service | Typical Range |
|---|---|
| Therma-Tru entry & patio door replacement (window replacement scope) | $4,500 – $15,000 |
| Impact window installation (impact-rated glass and frame systems) | $8,000 – $25,000 |
| Home addition with door and window integration | $45,000 – $130,000 |
What drives the number: whether we’re doing a one-for-one slab swap or opening up rough framing, whether the jamb and sill are salvageable, and whether the house sits on the fog side of Highway 1 where we spec heavier weatherstripping and storm door buffers. A free estimate from us is a written, line-item scope, not a vague ballpark. Call (866) 472-1908 to schedule yours.

FAQs – Therma-Tru Construction in Pacifica
The west side of Pacifica sits in a fog belt where marine-layer moisture and salt-laden air keep surfaces damp for long stretches, so door slabs, weatherstripping, and sills never fully dry between wet-season cycles. The same Therma-Tru door installed a half-mile east of Highway 1 will typically outlast one facing the open Pacific. That’s why we seal and spec west-side doors differently from day one. Call (866) 472-1908 if your ocean-facing entry is showing cracks, swelling, or rust.
It depends on how deep the rust has gone. Surface rust at the bottom rail or hinge stiles can often be ground, treated, primed, and repainted, and we’ll replace the weatherstripping that let the moisture in. If the steel has perforated or the door skin is compromised, repair is a losing bet in Pacifica’s coastal air, and we’ll recommend replacement. We’ll give you an honest read either way. Call (866) 472-1908 for an assessment.
Sometimes, yes. Pacifica sits under the California Coastal Commission’s jurisdiction, and depending on your home’s location and whether the replacement changes the door opening size or involves structural work, a coastal development permit may be required. A like-for-like door swap is usually exempt, but we check the specific requirements for your address before we start. Call (866) 472-1908 and we’ll look into it as part of your free estimate.
For Pacifica’s 1940s through 1970s stucco and wood-frame houses, we most often install Therma-Tru Fiber-Classic and Smooth-Star entry doors, which give the clean look of wood without the rot issues that plague original doors in the fog belt. Classic-Craft doors work well when a homeowner wants more traditional panel detailing and is willing to maintain the finish. The choice comes down to exposure, lot slope, and how much weather the door actually faces. Call (866) 472-1908 to talk through what fits your home.
We start with OEM Therma-Tru weatherstripping and sweeps for the factory fit, then add secondary measures on exposed elevations: storm doors to buffer wind-driven rain, upgraded threshold flashing, and sealants rated for constant damp and salt exposure. The sealing approach changes depending on whether your entry faces the open ocean or sits protected east of Highway 1. Call (866) 472-1908 for a door-by-door assessment.
