Therma-Tru Construction in San Bruno, CA | Workshop Contractors
We install, re-hang, and repair Therma-Tru fiberglass and steel entry doors across San Bruno, and the single biggest thing that separates our work here is this: the same door model often needs two completely different install approaches on the same block. San Bruno’s split between fog-exposed Crestmoor rebuilds and aging 1950s tract framing means a square jamb on one lot and a racked, settled rough opening on the next. We’re an independent San Bruno General Contractor, not a Therma-Tru authorized dealer, and we’ll tell you straight whether your door needs adjustment or full replacement. Call (844) 384-3361 for a free estimate.
Why San Bruno Residents Choose Us for Therma-Tru Service
Our crew has been working on Therma-Tru repair in Pacifica and across the Peninsula for years, long enough to know how these specific slabs and sills behave in San Bruno’s fog belt. We know the Smooth-Star line, the Fiber-Classic collection, Classic-Craft, and Therma-Tru patio and sliding systems, and we carry OEM sills, sweeps, weatherstrip, and multi-point hardware so we’re not waiting on a parts order when your door starts binding. Noel Figueroa grew up around tradesmen who taught him the difference between a door that’s hung square and one that just looks square, and that standard carries through every San Bruno job we take. We’re local to the Peninsula, we know this housing stock, and we show up when we say we will.

Common Therma-Tru Construction Problems We Solve in San Bruno
- Fog-belt moisture wicking into the sill and lower jamb. San Bruno’s cool damp summers push moisture into wind-exposed west and north elevations. The wood substrate under a fiberglass skin swells, the adjustable sill rusts, and the door starts dragging. We see this constantly on original 1950s tract homes where the flashing was never updated.
- Wind-driven rain past worn sweeps and weatherstrip. Onshore flow off the Pacific hits Smooth-Star doors hard in winter. You’ll feel a cold draft and find a damp threshold after storms. We replace the sweep and weatherstrip with OEM parts before the framing behind the door takes on water.
- Fiberglass slab finishes chalking and mildewing. The north Peninsula’s fog means paint and stain fail faster here than in sunnier inland markets. Bottom rails take the worst of it from splash. We refinish when the skin is intact, and we’ll tell you when it’s past saving.
- Doors going out of alignment as the house settles. Older San Bruno wood-frame homes rack over time. The latch misses the strike, the slab rubs the head jamb, and multi-point hardware binds. Re-hanging is often the fix, not a new door.
- Multi-point hardware failure from constant fog exposure. The locking mechanisms on Classic-Craft and Fiber-Classic doors corrode faster in damp coastal air. We source Therma-Tru OEM hardware where the door is still serviceable and only use quality aftermarket parts when OEM is discontinued.
Therma-Tru Service in San Bruno: What Local Conditions Mean for Your Equipment
San Bruno’s post-2010 Crestmoor rebuilds put modern-code homes directly across the street from original 1950s tract houses. On the same block, we may set a Therma-Tru door into new, square framing on one lot and re-square a racked, fog-dampened 60-year-old rough opening on the next. That’s not a marketing line; it’s the actual texture of working in this city. A Smooth-Star entry on a rebuilt Crestmoor home typically goes in clean, with a standard sill pan and fresh flashing. The same door on an original 1950s stucco-over-wood-frame house across the street often needs the jamb pulled square, hinges shimmed, and the threshold rebuilt before the slab will even sit right. On one Crestmoor block, we replaced a fog-dampened Fiber-Classic entry on a rebuilt home whose west-facing threshold kept wicking water, re-flashing the sill pan and swapping in an OEM adjustable sill and new sweep. Across the street on an original 1950s house, the same model door had to be re-hung because the aging frame had racked and the latch no longer met the strike. We squared the jamb, shimmed the hinges, and rebuilt the threshold with fresh weatherstrip so both entries shed the onshore wind and morning fog. Build it right the first time. The second time costs twice as much and nobody’s happy about it.
Therma-Tru Models & Products We Service in San Bruno
We work on the full Therma-Tru residential lineup: Smooth-Star fiberglass entry doors, the Fiber-Classic collection, Classic-Craft entry doors, and Therma-Tru patio and sliding glass door systems. Our parts approach is simple: we use Therma-Tru OEM sills, sweeps, weatherstrip, and hinge and multi-point hardware wherever the door is still serviceable, and only go to quality aftermarket seals when an OEM part is discontinued. If the slab skin is intact and the frame is sound, we re-seal and re-hang rather than sell a whole new door. But once the substrate is rotted through the bottom rail, replacement is the honest call, and we’ll walk you through Therma-Tru sales & service options without pressure.

AfterTherma-Tru Service Pricing in San Bruno
Door work in San Bruno spans a wide range because the underlying structure varies so much lot to lot. Re-hanging and re-sealing a serviceable Therma-Tru entry door typically runs lower than a full replacement, while a complete new entry door installation on a settled 1950s frame costs more because of the framing corrections involved. Your free estimate includes a straight assessment of whether the door can be saved or needs to come out, plus line-item pricing so you know exactly what you’re paying for. Call (844) 384-3361 to schedule yours, and we’ll give you a written quote before any work starts.

FAQs – Therma-Tru Construction in San Bruno
Your door is sticking because fog-belt moisture has likely swollen the wood substrate under the fiberglass skin at the sill, or because your older San Bruno home’s frame has settled and the rough opening is no longer square. We diagnose both on nearly every call in this city. Call (844) 384-3361 for an exact fix, and we’ll tell you which problem you have.
Yes, we can. The newer Crestmoor rebuilds sit directly across the street from original mid-century tract houses, so we regularly source the same Therma-Tru model and install it into two very different framing conditions on the same block. We handle both approaches so the doors look consistent from the street.
It shortens the life of the seals, the finish, and the sill hardware faster than inland climates, yes. The fiberglass slab itself holds up well, but San Bruno’s steady onshore wind and damp air wear out sweeps, weatherstrip, and bottom-rail finishes years sooner. We replace seals with OEM parts and refinished surfaces regularly.
No, we are an independent contractor. We are not authorized, sponsored, or warranty-backed by Therma-Tru. What we offer is honest diagnosis, OEM parts, and clean installation work. We’ll tell you when a warranty claim makes sense and let you handle it directly with the manufacturer.
It often will, especially on the 1940s to 1960s tract homes that make up much of San Bruno’s San Bruno service area. Replacing a door in an exterior wall typically requires a permit, and once the old frame comes out, we frequently find rot, settlement, or missing flashing underneath. We pull permits and fix the framing so the new door actually stays square. Call (844) 384-3361 for an exact quote, estimates are free.
