Therma-Tru Construction in Las Lomas, CA | San Bruno Construction
We provide independent Therma-Tru door installation, repair, and refinishing across Las Lomas, including full replacement of rot-damaged units and hardware alignment on older ranch homes. The thing that makes our Therma-Tru work different here is fit: most Las Lomas door openings were framed decades ago, before today’s rough-opening tolerances existed, so a factory-assembled unit rarely drops in without some re-framing. Call (866) 472-1908 for a free estimate, and we’ll tell you straight what your opening needs.
Why Las Lomas Residents Choose Us for Therma-Tru Service
We’ve hung, adjusted, and re-weathered enough Therma-Tru doors and sidelights in Pajaro Valley homes to know how the brand’s fiberglass slabs, rot-resistant frames, and multipoint hardware behave under coastal fog and ag-zone dust. We quote and install Therma-Tru as an independent contractor, not as a dealer or factory-authorized installer, which means we call the repair honestly: refinish when the slab is sound, replace when the core or frame is gone.
Noel Carvalho grew up in San Bruno and trained in construction technology at Skyline College, where he learned to read plans and understand load paths before touching a tool. Over the past two-plus decades he’s run residential projects across San Mateo County and the Pajaro Valley, so he knows what a fog-soaked threshold does to a door frame and what a settling ranch foundation does to a latch. We coordinate the trades so you don’t have to, and we’re the single point of accountability on the whole job. For genuine OEM hardware and honest fit assessments, Therma-Tru sales & service starts with a conversation, not a hard sell.

Common Therma-Tru Construction Problems We Solve in Las Lomas
- South-facing fiberglass fading and chalking. Las Lomas lots are open with little shade, so a Fiber-Classic door on the south wall takes years of direct UV. The skin chalks and the color washes out, but the slab itself is almost always structurally fine. We refinish and re-weather these rather than replace.
- Weatherstripping and sweeps flattened by fog cycles. Pajaro Valley fog cycles work weatherstripping hard: damp air swells it, dry spells bake it, and after a few seasons the sweep tears and the jamb lets wind-driven rain past the threshold. We see stained interior jambs on doors that looked fine from outside.
- Multi-point hardware drifting out of alignment. Older ranch homes in Las Lomas settle. Foundations shift a fraction of an inch, the rough opening twists, and the multi-point hardware that latched cleanly at install starts sticking. We re-square the opening and re-align the hardware instead of forcing the slab.
- Moisture wicking through trimmed slab edges. On custom builds where the rough opening was uneven, someone trimmed a Smooth-Star slab on site and didn’t re-seal the factory-primed edge. That edge wicks fog moisture and swells. We see it often on additions to mid-century homes.
- Rot where the threshold meets the jamb. Las Lomas gets real winter rain. When a threshold was installed even slightly out of level, water pools at the corner, wicks into the jamb, and rots the frame from the bottom up. By the time the door drags on the sill, the damage is usually deeper than it looks.
Therma-Tru Service in Las Lomas: What Local Conditions Mean for Your Equipment
Many Las Lomas door openings we work on are in mid-century ranch and modest custom homes on large ag-residential lots, so a Therma-Tru entry unit often has to be re-framed into an out-of-square rough opening that was never built to today’s rough-opening tolerances. That’s a fit problem that doesn’t come up in newer tract housing, and it changes the job: we don’t just swap a slab and call it done. We check the rough opening with a level and square before we order or pull anything, because a factory-assembled Benchmark unit needs a true opening to seal properly. In practice, that means we’re often shimming, planing, or re-framing an inch or two before the new door goes in, and the extra hour up front is what keeps the door latching cleanly and sealing against fog-driven rain for years afterward. Your Therma-Tru door is only as good as the frame it’s set into.
Therma-Tru Models & Products We Service in Las Lomas
We install and service the full residential lineup: Fiber-Classic fiberglass entry doors, Smooth-Star smooth fiberglass doors, Classic-Craft American Style collection doors, and Benchmark factory-assembled door systems. We source Therma-Tru OEM hinges, sills, sweeps, and weatherstripping for warranty-eligible hardware, and turn to quality aftermarket glass and finish products when the original is discontinued. On solid fiberglass slabs with cosmetic fading, we refinish and re-weather rather than replace. Full replacement makes sense when the frame, threshold, or slab core is water-damaged, which we see on Las Lomas doors that have taken years of winter rain at the threshold. Our Las Lomas service area coverage means we can usually have the right part on the truck the first trip.

FAQs – Therma-Tru Construction in Las Lomas
Yes, and it’s simpler than most people expect. Door replacement is almost never a permit-triggering project in itself, so well and septic requirements don’t typically come into play. The exception is when the door opening is part of a larger addition or structural change, which is the case on some Las Lomas ranch homes and in nearby communities like Amesti where an entry is being moved or widened. If your project does require county review, we’ll walk you through what’s needed for your specific lot. Call (866) 472-1908 and we’ll tell you where your project stands.
UV exposure on an open, shade-free Las Lomas lot causes the factory finish to chalk and fade over years of direct sun, especially on Fiber-Classic and Smooth-Star skins. It’s cosmetic, not structural: the fiberglass slab itself is fine underneath. We refinish and re-weather these doors rather than replacing the whole unit, which costs substantially less and restores the original look. Call (866) 472-1908 for a refinishing quote.
In Las Lomas and Corralitos it’s usually the house. Mid-century ranch foundations settle over decades, and the rough opening that was square when the door was installed has shifted a fraction. The door slab is often still true, but the frame it’s set into isn’t. We re-square the opening and re-align the multi-point hardware rather than planing the slab, which would compromise the seal. Call (866) 472-1908 and we’ll diagnose it on site.
We do, and it’s the right way to do it. When we’re managing a full bathroom remodel ($9,000 – $28,000) or a walk-in shower installation ($4,500 – $12,000), we don’t want a door contractor working around us or leaving the opening unsealed overnight. Since we’re already on site and coordinating every trade, adding Therma-Tru door work to a Las Lomas remodel keeps the schedule clean and the rough openings sealed. Call (866) 472-1908 and we’ll scope the whole job at once.
First, don’t ignore it. Water pooling at the threshold corner wicks up into the jamb and rots the frame from the bottom, and by the time the door drags on the sill the damage has spread further than it looked. We replace the threshold, re-flash the jamb against fog-driven rain, and if the slab core is water-damaged, replace the unit. A threshold reseal is a fraction of the cost of a full replacement. Call (866) 472-1908 to get it looked at before the next wet season.
