Therma-Tru Construction in Colma, CA | Ashford Contractors
Therma-Tru construction service in Colma means installing and repairing fiberglass entry door systems in buildings owned by cemetery districts, mortuaries, and the handful of commercial properties along El Camino Real, similar to our Therma-Tru repair in Broadmoor. We’re an independent contractor with deep Therma-Tru experience, and what separates our work here is that we set doors to survive damp masonry openings, fog-belt sills, and perpetual-care irrigation running against foundations. Call (877) 752-3868 for a free estimate on any Therma-Tru repair or replacement in Colma.
Why Colma Residents Choose Us for Therma-Tru Service
Colma isn’t a residential town. That changes what door work looks like. The clients calling us are cemetery district facilities managers, mortuary directors, and the owners of service buildings on El Camino Real. They don’t need a handyman who’s hung doors in a San Mateo tract home. They need a crew that knows how a Therma-Tru fiberglass slab behaves when it’s set into a 60-year-old masonry opening where fog never burns off and sprinklers run every morning.
Glen Mossier, owner of Ashford Contractors, has spent two decades on the Peninsula learning what damp, sun-starved air does to building envelopes. He trained in construction technology at Skyline College in San Bruno and has built a reputation for structural remodels and additions without shortcuts. His rule is simple: build it right the first time, and you won’t be rebuilding it in ten years. That’s the standard we apply to every Therma-Tru door we hang in Colma. We’re independent, not manufacturer-affiliated, so our loyalty is to the building owner, not a warranty department.

Common Therma-Tru Construction Problems We Solve in Colma
- Sill and threshold rot on Smooth-Star entries. The persistent fog keeps the sill pan wet, and factory finishes break down at the bottom rail. In Colma, standing water from nearby irrigation makes this worse. We replace rotted sills with genuine Therma-Tru OEM sill pans and set the new unit on a properly sloped base so water moves away from the opening.
- Fiberglass skin blistering and peeling on north-facing elevations. Colma sits in the fog belt, and surfaces that never fully dry between fog cycles lose their finish faster than sun-exposed doors elsewhere on the Peninsula. We use Therma-Tru’s factory-finish touch-up systems to restore weather protection before the skin degrades further.
- Frame separation at sidelite joints on Classic-Craft systems. When door units get set into masonry openings at cemetery offices or service buildings with poor drainage, moisture wicks into the frame and causes swelling. The joints open, the door loses its seal, and the problem only accelerates. We rebuild the opening, reset the unit, and correct the drainage.
- Corroded hinges, locksets, and strike plates on Fiber-Classic doors. Salt-laden marine fog rolls up from the coast and settles on El Camino Real commercial frontage. Hardware corrodes fast. We fit quality aftermarket hinges and hardware where OEM parts have failed, while keeping Therma-Tru OEM sills, sweeps, and sill pans so the door weathers as intended.
- Bottom rail swelling behind a sill that never dries. On a columbarium addition off El Camino Real, our crew pulled a Smooth-Star entry whose bottom rail had swelled and rotted behind a sill holding standing water from nearby irrigation. We rebuilt the opening, reset a new Therma-Tru unit on a sloped sill pan with OEM sweep and flashing, and the door sealed dry before the next memorial service.
Therma-Tru Service in Colma: What Local Conditions Mean for Your Equipment
Colma’s exterior door work is almost never residential. The town is legally dedicated to cemeteries and death care, with over a million buried residents and only a few hundred living ones. The buildings that need Therma-Tru service here are cemetery district offices, mortuary and columbarium facilities, and the commercial strip along El Camino Real. We set entries to survive damp, low-sun masonry openings with perpetual-care irrigation running nearby. That combination, fog-belt moisture, masonry walls that wick water, and sprinklers soaking the ground within feet of the threshold, doesn’t exist in neighboring towns. Daly City has housing stock. South San Francisco has housing stock. Colma has none. A door that lasts fifteen years in Pacifica or San Bruno can rot out in five here if the sill pan isn’t sloped correctly or the flashing isn’t lapped right. When you choose us, you’re hiring a contractor who understands that Colma door work starts with the drainage and the substrate, not the slab itself.
Therma-Tru Models & Products We Service in Colma
We work across the full Therma-Tru lineup: Smooth-Star fiberglass entry doors, Fiber-Classic door slabs and sidelites, Classic-Craft American Style collection, and Benchmark prehung systems. For parts, we use genuine Therma-Tru OEM sills, sweeps, sill pans, and factory-finish touch-up products so the door keeps its intended weather performance. We fit quality aftermarket hinges and hardware where OEM hardware has corroded out, and we stock a focused inventory of common sills and sweeps locally so Colma turnaround stays fast. When a door has frame rot or delaminated fiberglass, honest repair usually loses to replacement. We’ll tell you which side of that line your unit is on before any work starts. For broader exterior or interior work around a door installation, we also handle Therma-Tru sales & service as part of full-scope projects.

FAQs – Therma-Tru Construction in Colma
Fiberglass skins do not rot, but the bottom rail assembly often includes wood or composite core material that does. In Colma, fog keeps the sill pan wet and finishes break down at the bottom rail, then irrigation water and masonry wicking keep the core saturated. The fiberglass outer layer hides the rot until the door sags or the sweep fails. We replace the unit and reset it on a properly sloped, flashed sill pan. Call (877) 752-3868 for an exact assessment.
Yes, but the opening needs more prep than a standard wood-framed rough opening. We grind or clean the masonry surface, install a continuous sill pan with a positive slope, flash the jambs, and anchor the unit to the masonry. Colma’s fog and the irrigation running against many cemetery building foundations make the flashing and drainage the most important part of the job. Call (877) 752-3868 to schedule a look at your specific opening.
Sometimes. Small gaps can be corrected with proper re-shimming and joint repair. If the frame has swollen from prolonged moisture, the structural integrity is compromised and replacement becomes the more honest option. We inspect the frame before recommending either path, and we’ll give you a straight answer on cost. Estimates are free.
Fog keeps surfaces wet, and wet surfaces never let factory finishes fully cure or adhere long-term. Blistering and peeling on damp, north-facing elevations is common in Colma. We use Therma-Tru factory-finish touch-up systems and schedule work for the dry season when possible, so the finish bonds properly. Call (877) 752-3868 if your door’s finish is failing.
We do, and we handle it as a single point of contact. If a cemetery facility needs a new Therma-Tru entry plus a roof repair or a bathroom remodel, one contract covers all of it. We coordinate schedules, pull permits, and manage every scope without you chasing subs. Call (877) 752-3868 for a combined estimate.
