Therma-Tru Construction in Moss Beach, CA | Milpitas Construction
We provide independent Therma-Tru door installation, repair, and replacement across Moss Beach (94038), and the one thing that separates our Therma-Tru work here from anywhere else is the salt fog. We’re Milpitas Construction, led by Ken Stafford, a Moss Beach General Contractor who has spent years watching coastal air chew through door hardware that inland homes never think twice about. If your Therma-Tru entry is sagging, sticking, or leaking at the threshold, call (877) 752-4194 for a free estimate. We know these doors at the component level, and we know what Moss Beach does to them.
Why Moss Beach Residents Choose Us for Therma-Tru Service
Therma-Tru builds a genuinely good fiberglass door. The slab itself holds up. What fails in Moss Beach is everything around it: the sill pan, the jamb legs, the hinges, the weatherstripping. Most door companies swap the slab and call it done. We don’t, because we’ve pulled too many “new” doors off Moss Beach homes only to find the rough opening was never squared and the threshold was never flashed for wind-driven rain.
Ken Stafford grew up near the Milpitas BART station when that corridor was still warehouse lots and family-owned shops, and he built his trade on a simple rule: build it right the first time. The Bay Area doesn’t give you a free pass on shortcuts, and the Moss Beach coast is even less forgiving. Our crews approach every Therma-Tru job as a weatherproofing job first and a door job second. We spec materials by name, so you know exactly what’s going into your home.
What to Look for in a Moss Beach Therma-Tru Installer
- Do they talk about the rough opening? In older Moss Beach beach cottages and ranch-style homes, decades of settling and moisture movement rack the frame. A contractor who doesn’t re-square the opening before setting a new Therma-Tru slab is selling you a door that will bind and leak within a season.
- Do they use marine-grade fasteners? Untreated and even some plated screws rust through under salt air in under two years. We use stainless or hot-dip galvanized hardware on every exterior door we touch in Moss Beach.
- Do they understand county coastal review? Moss Beach is unincorporated San Mateo County, and some exterior opening changes pull into coastal-development review. A contractor who doesn’t flag that up front can leave you with a stop-work order. We walk every homeowner through the permit question before we tear anything out.

Common Therma-Tru Construction Problems We Solve in Moss Beach
- Bottom-rail and sill rot from persistent marine moisture. The constant damp and salt keep the bottom of the door and the threshold perpetually wet. On older Therma-Tru Fiber-Classic entries near the bluff edge, we regularly find rotted jamb legs and decayed sill pans while the fiberglass slab is still perfectly sound.
- Corroded hinges and strikes that let the slab sag. Salt air eats standard door hardware fast in Moss Beach. When hinges rust through, the door drops, the latch stops aligning, and the deadbolt starts catching. We replace with stainless hardware and re-align the slab.
- Weathered sweeps and weatherstrip failing against wind-driven winter rain. Storms off the Pacific push water through worn seals and into the rough opening. You’ll see stained interior trim and swollen framing before you realize the door seal is gone. We replace with OEM-spec sweeps and compression weatherstrip rated for coastal exposure.
- Out-of-square rough openings in older beach cottages. Homes along Highway 1 that have settled for fifty or sixty years rarely have plumb, square door openings anymore. A new Therma-Tru slab won’t swing or latch clean until the framing is corrected. We re-square, re-shim, and re-hang properly.
- Fog-belt moisture intrusion at the threshold flashing. The same salt fog that rusts anything metal also finds every gap in poorly flashed sill pans. We rebuild thresholds with properly sloped pans and marine-grade flashing so water sheds away from the rough opening, not into it.
Therma-Tru Service in Moss Beach: What Local Conditions Mean for Your Equipment
Moss Beach sits on a foggy, salt-laden marine terrace just north of Half Moon Bay Therma-Tru service territory, and that placement shapes every Therma-Tru installation we do here. This is unincorporated county land: there’s no city building department, so permits run through San Mateo County, and on bluff-edge lots above the beach, much of the housing sits in coastal-development review. That means something a homeowner in inland San Mateo County never deals with: even a Therma-Tru entry or patio door that changes an exterior opening on a permitted remodel can get pulled into coastal and geotechnical setback review. You can’t just cut a new opening and swap a door. The county wants to know the bluff setback, the erosion overlay, and sometimes the geotech report before they’ll sign off.
We handle that paperwork conversation up front, because discovering it mid-project is how Moss Beach remodels stall for months. On a fog-worn beach cottage off Highway 1 near the bluff edge, our crew found a Therma-Tru Fiber-Classic entry with a rotted bottom rail and a sill pan that had been holding salt water for years. We re-squared the racked rough opening, rebuilt the threshold with a properly sloped sill pan and marine-grade flashing, and set a new Smooth-Star slab with stainless hinges and fresh weatherstrip. We walked the homeowner through the county coastal-permit question up front so the exterior-opening change cleared review before we tore anything out. That’s the difference between a door company and a general contractor who works the Moss Beach coast.
Therma-Tru Models & Products We Service in Moss Beach
We install and service the full Therma-Tru fiberglass lineup: Fiber-Classic, Smooth-Star, Classic-Craft premium series, and Therma-Tru patio and hinged exterior door systems. We’re an independent contractor, not a Therma-Tru dealer or factory-authorized agent, which means we source OEM and OEM-spec parts where they exist and we’re not tied to any factory program that pushes a full-door replacement when a sill rebuild would do. For Moss Beach turnaround, we keep common threshold components, sweeps, and stainless hinges ready, and anything model-specific arrives within days. When the slab is sound, we reseal the sill and replace hardware rather than sell you a new door. When the bottom rail is rotted through, honest replacement is cheaper than repeated patching.

FAQs – Therma-Tru Construction in Moss Beach
No. Milpitas Construction is an independent Therma-Tru service provider. We install and repair Therma-Tru doors using OEM and OEM-spec components, but we’re not factory-authorized or manufacturer-affiliated. That independence means we recommend repairs when they make sense rather than pushing a replacement to satisfy a dealer program. Call (877) 752-4194 and we’ll give you an honest assessment.
We recommend checking Moss Beach door sills and weatherstripping every spring and fall, and after any winter storm with sustained wind-driven rain. Salt air and fog keep thresholds damp for months at a time, and worn sweeps let that moisture reach the rough opening. A ten-minute visual check catches most failures before framing damage starts. If you find rot, rust, or daylight under the door, call (877) 752-4194 for a free estimate.
Yes, where they exist. We use Therma-Tru OEM and OEM-spec hinges, sills, sweeps, and weatherstripping. For fasteners, we upgrade to marine-grade stainless or hot-dip galvanized because standard fasteners simply don’t survive the Moss Beach salt air. The door may be Therma-Tru, but the screws holding it should be better than factory stock for this climate.
We service the full fiberglass lineup: Fiber-Classic, Smooth-Star, Classic-Craft premium series, and Therma-Tru patio and hinged exterior door systems. If you have an older Therma-Tru entry or patio door in Moss Beach and aren’t sure of the model, we can identify it on-site during the estimate.
Most Moss Beach Therma-Tru replacements run between $2,500 and $6,500 for a full entry system with a re-squared opening, new threshold flashing, stainless hardware, and coastal-grade weatherstripping. Straight slab swaps with re-shimming run less, usually $900 to $2,800. The final number depends on opening condition, model selection, and whether county coastal review applies. Call (877) 752-4194 for an exact quote. Estimates are free.
