Therma-Tru Construction in Lexington Hills, CA | San Bruno Construction
We provide independent Therma-Tru door replacement, repair, and installation across Lexington Hills, CA. The thing that separates our Therma-Tru work here from anywhere else in the county: every exterior door we spec must clear Cal Fire’s wildland-urban interface review under Chapter 7A before the building department will even look at the permit. That fire-clearance gate, not the door itself, is what catches most homeowners off guard. Our crews work on Therma-Tru fiberglass and steel entry systems in the Santa Cruz Mountains every week, so we know the brand’s hardware, hinge, and finish quirks firsthand — including our Therma-Tru repair in Scotts Valley and nearby mountain communities. Call (866) 472-1908 to discuss your door or any construction scope.
Why Lexington Hills Residents Choose Us for Therma-Tru Service
Noel Carvalho grew up off El Camino Real in San Bruno, trained in construction technology at Skyline College, and has spent the past two-plus decades running residential projects across San Mateo County. That background matters when you’re dealing with a Therma-Tru door on a 1970s redwood cabin that has settled half an inch out of square, whether you need Los Gatos Therma-Tru service or help further up the peninsula. We’re not authorized by Therma-Tru, and we don’t pretend to be. Independence means our only incentive is a door that fits your opening, passes WUI review, and seals against mountain weather. We source OEM Therma-Tru slabs, hinge sets, sills, and weatherstrip whenever the frame is salvageable. We coordinate the trades so you don’t have to.

Common Therma-Tru Construction Problems We Solve in Lexington Hills
- Bottom-rail cracking on fiberglass slabs. Years of winter driving rain against a redwood cabin with no storm door soaks the lower rail. If the sill pan wasn’t flashed correctly, the slab delaminates and the door stops sealing. We see this constantly in Lexington Hills.
- Rust at the bottom rail and hinge-stile corners on steel doors. Summer fog and winter storms combine with missing storm-door clearance. Once rust creeps under the paint, the door faces blister and the lock bores loosen.
- Warped or bowed wood-grain fiberglass lines. Hot, dry summers on south-facing exposures in Lexington Hills cause hinge bind and latch misalignment. A door that’s never had an overhang or storm door to shield it compounds the problem.
- Failed fire-safe clearance inspections on old Therma-Tru installations. A door that still “works” may not meet Cal Fire Chapter 7A ignition-resistant requirements. On decks or exterior wall replacements, that means the door fails the county fire-safe clearance inspection before plan check is even finished.
- Seized multipoint locks and worn hinge sets. The Therma-Tru multipoint hardware is solid, but mountain air and deferred maintenance take a toll. We rebuild hinge sets and weatherstrip with OEM parts before they cause slab damage.
Therma-Tru Service in Lexington Hills: What Local Conditions Mean for Your Equipment
In Lexington Hills, the county fire-safe clearance inspection is the real gatekeeper on a permit, not the building department. Exterior door replacements on decks or newly framed walls must use ignition-resistant assemblies under WUI rules. That changes how we spec a Therma-Tru door here. A Smooth-Star fiberglass slab with a flashed metal sill pan, plus ignition-resistant trim, clears fire review cleanly the first time. A wood-edge Fiber-Classic with the original trim detail may not. Homeowners off Old Santa Cruz Highway and nearby roads learn this mid-project. We spec doors that pass fire review before they ever get to plan check because the alternative, a door that gets ordered, delivered, and then fails inspection, costs you a month and a re-order fee. On a sloped, wooded lot off Old Santa Cruz Highway, our crew replaced a delaminated Therma-Tru Fiber-Classic entry door whose bottom rail had soaked out under a missing storm door. We specified a Smooth-Star slab with a flashed sill pan and ignition-resistant trim to satisfy the county fire-safe clearance inspection. The homeowner kept the existing frame, which was sound, and we rebuilt the hinge set and weatherstrip with OEM Therma-Tru parts. The door now seals through winter storms and passed the WUI review without a second visit.
Therma-Tru Models & Products We Service in Lexington Hills
We work on the full Therma-Tru residential lineup: Smooth-Star, Fiber-Classic, Classic-Craft, and Pulse. Most Lexington Hills homes have Smooth-Star or Fiber-Classic slabs from the 1990s and early 2000s. Classic-Craft, the wood-grain line, is common on higher-end remodels. Pulse is the newer premium series we install when a homeowner wants an upgrade that meets WUI ignition-resistant standards out of the box. Our repair-versus-replace stance is straightforward: if the slab is delaminating or the frame is rotted at the sill, replacement is cheaper than chasing a repair that won’t pass WUI inspection. If the slab is sound, a hardware and sill rebuild is often the right call. We stock common OEM weatherstrip, sills, and hinge sets for faster Lexington Hills turnaround, and source quality aftermarket multipoint and sill-pan components only where an exact OEM match isn’t available. See our Therma-Tru sales & service page for more on the product lines.

FAQs – Therma-Tru Construction in Lexington Hills
Yes, if it’s specified as an ignition-resistant assembly. The door slab, frame, sill pan, and trim all factor into the review. We spec Smooth-Star or Pulse slabs with flashed metal sill pans and ignition-resistant trim because they clear review without a second visit. Call (866) 472-1908 to confirm your specific opening.
If the crack is surface-level and the slab isn’t delaminating, a sill rebuild, re-flashing, and weatherstrip replacement often solves it. If the bottom rail has soaked through and the fiberglass is separating, replacement is the honest call because a delaminated slab won’t pass WUI review and will keep leaking. Call (866) 472-1908 and we’ll tell you which one you have.
Yes. We stock common OEM Therma-Tru weatherstrip, sill pans, and hinge sets from the Smooth-Star and Fiber-Classic generations. Classic-Craft and Pulse parts are ordered directly. We use quality aftermarket multipoint and sill-pan components only where an exact OEM match isn’t available.
Not directly, but a properly sealed and flashed Therma-Tru door with a good sill pan keeps winter storm water out of the entry, which reduces water intrusion behind the siding and helps maintain the building envelope during the wet months when erosion-control rules limit construction. That means fewer callbacks and a tighter structure between fire season restrictions.
No. We’re independent Therma-Tru specialists serving Lexington Hills service area. Independence means we spec the door that fits your opening and passes WUI review, not the one a manufacturer program incentivizes us to push. Call (866) 472-1908 for a straight answer on pricing.
