Therma-Tru Construction in San Bruno, CA
We provide independent Therma-Tru door service across San Bruno, from re-hanging a dragging Fiber-Classic slab to full entry system replacement on a Crestmoor rebuild. What makes our Therma-Tru work different here is simple: we know how San Bruno’s fog, hillside settling, and mixed-era housing stock actually stress these doors, so we diagnose based on what’s happening at your threshold, not a generic checklist. Call (877) 373-9230 for a free estimate. We’re not manufacturer-affiliated or authorized; we’re a licensed San Bruno General Contractor who’s worked on enough of these doors to know exactly when they can be saved and when they’re done.
Why San Bruno Residents Choose Us for Therma-Tru Service
Noel Cardenas has spent years setting and retrofitting Therma-Tru fiberglass and steel entry and patio doors into San Bruno’s built-out ranch housing, from Crestmoor rebuilds to steep west-side remodels. Our crew knows the brand’s slab construction, glass lite options, and sill and threshold systems well enough to tell you honestly when a Therma-Tru door can be re-hung and re-sealed versus when the skin, seal, or frame has failed for good. We use genuine Therma-Tru replacement slabs, sills, sweeps, weatherstrip, and glass/seal kits that match the existing series, so the door fits the frame it was engineered for. When OEM is unavailable, we reach for quality aftermarket hardware, never knockoff parts that don’t seat right. As a full-scope contractor, we also handle the work that often surrounds a door replacement in San Bruno, including our Home Remodeling in San Bruno, roof repair, and window replacement. One contractor. Every phase.

Common Therma-Tru Construction Problems We Solve in San Bruno
- Bottom-up jamb rot from fog and marine damp: San Bruno’s near-constant fog keeps exterior slabs and sills wet for months at a time. On older 1940s – 60s stucco ranch homes, we regularly find the wood frame jamb rotted at the base while the fiberglass skin still looks fine from the street. We pull the trim, cut out the soft framing, and rebuild the rough opening square before re-hanging the door.
- Slab drag and latch misalignment from settling: Settling and minor ground movement in hillside and older tract lots twist rough openings out of square. The door drags on the sill, the deadbolt stops aligning, and the weatherstrip gaps at one corner. We re-shim the frame, adjust the hinges and strike plate, and replace the sweep so the door seals tight again.
- Sidelight and lite seal failure: Sun-exposed street-facing entries with little or no porch overhang fade, chalk, and develop hairline cracks in the fiberglass skin. The factory glass seal around lites and sidelights also breaks down, letting fog-season moisture into the door core. We replace sealed glass kits and re-skin where the core is sound, and replace the slab where it isn’t.
- Threshold wicking on under-flashed openings: On Crestmoor-area rebuilds and adjacent older homes, mismatched construction standards mean a new Therma-Tru door can be set against an out-of-square or under-flashed opening that never leaks on paper but wicks water at the threshold through wet winters. We probe and measure every opening before we set a door, because assuming the same fix works house to house doesn’t hold up in San Bruno.
- Fiberglass skin delamination: Older Therma-Tru entries with foam-core construction can delaminate when moisture works its way past a failed seal or cracked skin. The door surface develops soft spots, bubbles, or visible separation. If the skin and core are compromised, replacement is the honest call; repair just buys you a year before the same failure returns.
Therma-Tru Service in San Bruno: What Local Conditions Mean for Your Project
The 2010 PG&E pipeline explosion in Crestmoor rebuilt a whole pocket of roughly 1960s homes to modern code at once, which means in that tract a Therma-Tru entry can sit next to a door on a neighboring house that is decades newer in framing and flashing standard. We learned this the hard way on a Crestmoor tract home rebuilt after 2010: the Therma-Tru Fiber-Classic entry was dragging and leaking at the sill even though the slab looked fine from the street. Pulling the interior trim revealed a rotted jamb and a threshold that had been flashed too shallow for the winter runoff coming off the slope. We cut out the soft framing, rebuilt the rough opening square, installed a proper sill pan and new OEM sweep and weatherstrip, and re-hung the original slab so it latched cleanly and stopped wicking. On one side of a property line, the rough opening was framed and flashed to 2011 code; on the other, it was still holding a 1962 header. A door install that ignores that difference fails quietly for years before it fails loudly. That’s why we measure and probe each opening in San Bruno rather than assuming the same fix works house to house.
Therma-Tru Models & Products We Service in San Bruno
We service the main Therma-Tru product families you’ll find across San Bruno’s ranch housing: the Fiber-Classic fiberglass entry door series, the Smooth-Star fiberglass entry door, the Classic-Craft premium entry line, and Therma-Tru fiberglass patio and hinged exterior door systems. Our parts approach is simple: we use OEM slabs, sills, sweeps, weatherstrip, and glass/seal kits that match the existing series so the door fits the frame it was engineered for. If the fiberglass skin and core are sound and only the sill, sweep, seal, or hardware have failed, we repair and re-fit. If the skin is delaminated, the glass seal is breached, or the frame is rotted and out of square, replacement is the honest call. We’re independent, so that call is based on what’s in front of us, not a quota.

AfterTherma-Tru Service Pricing in San Bruno
Therma-Tru door repair and replacement pricing depends on the scope: a sill and sweep replacement runs less than a full slab re-skin, and a full entry system replacement with sidelights costs more than a simple slab swap. What drives the cost in San Bruno specifically is opening condition. If the frame is rotted or out of square, we rebuild the rough opening before we set the door, and that labor is where older hillside and tract homes add real cost. Here are the ranges for the work we most often do alongside a Therma-Tru entry in San Bruno:
| Service | Price Range |
|---|---|
| Window Replacement | $4,500 – $15,000 |
| Roof Repair | $400 – $1,800 |
| Bathroom Remodel | $9,000 – $28,000 |
Every estimate includes a written line-item breakdown of materials and labor, so you can see exactly where the money goes before work starts. Call (877) 373-9230 to get your Therma-Tru door looked at and priced. Estimates are free.

FAQs – Therma-Tru Construction in San Bruno
Yes. We don’t need to match the original install to do the job right. What we do need is to see how the rough opening was framed and flashed, because Crestmoor-area construction standards vary house to house, sometimes dramatically. We’ll measure the opening, probe for rot, and spec a door that works with the framing you actually have. Call (877) 373-9230 for an exact quote.
Usually the house. San Bruno’s damp winters swell wood framing, and hillside settling shifts rough openings out of square over time. The Therma-Tru slab is often fine; the frame around it isn’t. We’ll re-shim, re-hang, and re-seal the door before we ever recommend replacing a sound slab. If the slab itself is delaminating or cracked, we’ll show you and explain why.
Look for soft spots, bubbles, or visible separation in the fiberglass skin, plus any fogging or moisture between the glass panes in lites and sidelights. Those signal the core or seal has failed and repair won’t hold. If the only issues are a worn sweep, a cracked sill, or misaligned hardware, the slab is usually worth saving. We’ll tell you straight either way.
It does. Runoff channels down the slope toward your foundation, and a threshold that isn’t flashed with that water in mind will wick moisture through our wet winters. We build sill pans and drainage details that account for the grade, not just the door opening. It’s one of the reasons we measure and probe every opening before we set a door.
We handle the whole envelope. If your Therma-Tru entry sits next to a tired bathroom that needs a full remodel, rotten window trim, or a roof that’s been patched one too many times, we can pull it all under one contract. It’s why we’re set up as a general contractor rather than a door-only shop. Call (877) 373-9230 for a free estimate on the full scope.
