Therma-Tru Construction in San Francisco, CA | Bradford Remodeling Co San Francisco
We provide independent Therma-Tru door installation and repair across San Francisco, from the Richmond District to Bernal Heights. We’re not a manufacturer-authorized dealer, and we don’t pretend to be. What we are is a crew that has spent two decades hanging, squaring, and weather-sealing Therma-Tru doors on the exact kind of homes San Francisco throws at you: wood-frame Victorians with shifting foundations, Edwardians with soft-story garages, and fog-belt stucco boxes that never quite dry out. Call (831) 610-5598 for a written estimate before any work starts.
Why San Francisco Residents Choose Us for Therma-Tru Service
Therma-Tru doors are engineered well, but they’re only as good as the opening they’re set in. In San Francisco, that opening is rarely square. Curtis Lane, our owner, learned to read structural drawings at Los Angeles Trade-Technical College before he ever ran a crew, and he’s spent enough time in Outer Sunset gut-and-rebuilds to know exactly how fog-driven moisture moves through older balloon-frame walls. That matters when a Classic-Craft door starts delaminating along the bottom rail and the real cause is an unsealed lockset cutout wicking water uphill. Therma-Tru sales & service is only worth calling if the company picks up the phone and shows up. We answer live, 24/7, and our technicians are background-checked and uniformed. No voicemail runaround.

Common Therma-Tru Construction Problems We Solve in San Francisco
- Fiberglass skin delamination at the bottom rail. San Francisco fog keeps door bottoms damp for months at a time. When locksets, mail slots, or kick plates were cut without sealing the raw fiberglass edge, moisture wicks in and separates the skin from the core. We see this most on west-facing doors in the Sunset and Richmond.
- Winter slab warping from temperature differentials. Unheated San Francisco hallways stay cold while the exterior gets afternoon sun. Classic-Craft and Smooth-Star slabs can bow when the inside face and outside face expand at different rates. We check slab flatness before condemning a door, because sometimes the fix is weatherstripping, not replacement.
- Hinge-side sagging on decorative glass doors. Heavy glass inserts on Classic-Craft fiberglass entry doors put real torque on hinges. In soft-story Victorians where the floor has settled, that weight loads the hinge side unevenly and the door starts dragging on the latch side.
- Corner gasket and weatherstrip compression set. Homes on Richmond and Sunset sand-dune soil settle incrementally, and that settlement compresses frame corner pads and gaskets unevenly. Air leaks show up first at the top corners and along the latch side.
- Frame racking from foundation movement. Adobe clay soils on the city’s slopes, combined with steep grades and drainage that was marginal when the house was built, can rack a door frame by a quarter inch or more. The slab may be fine. The rough opening isn’t.
Therma-Tru Service in San Francisco: What Local Conditions Mean for Your Equipment
Here’s something that doesn’t show up on most Therma-Tru service pages: San Francisco’s Planning Department requires any replacement front door on a landmarked Victorian or Edwardian home to match the original in material, panel profile, and finish. That sounds like a problem for fiberglass doors, but it isn’t, if you know the product line. Painted fiberglass doors from Therma-Tru’s Classic-Craft line can satisfy the review when paired with custom wood-grain staining and reproduction hardware. Our crews have done exactly this on landmarked homes in the Haight and Pacific Heights. Cross the Bay to Oakland or Berkeley and the rules change. San Francisco holds a unique line here, and if you’re a homeowner sitting in front of a Planning Department review, you need a General Contractor in San Francisco who has actually run that process, not one who’s about to learn it on your front porch.

A straight number, real scope, no surprises at close-out. That’s the Garrison Standard, and it applies to every Therma-Tru job we run in San Francisco. What drives cost is almost always what we find underneath: a racked rough opening, rot in the sub-sill, a foundation that moved and took the frame with it. We write the price after the opening is inspected, and we put it in writing before any work starts. Your free estimate includes an on-site inspection, a written scope, and a line-item price.

FAQs – Therma-Tru Construction in San Francisco
Yes. Replacing a front door on any landmarked or potentially landmark-eligible Victorian or Edwardian home requires Planning Department review, and the replacement must match the original in material, panel profile, and finish. Painted Therma-Tru Classic-Craft fiberglass doors with custom wood-grain staining can pass that review, but you need a contractor who has worked the process. We have. Call (831) 610-5598 for an exact scope on your address.
The fiberglass slab itself won’t rot the way wood does. What fails is the cut edge where moisture gets in. Lockset bores, mail slot cutouts, and kick plate screw holes all expose raw fiberglass, and when those edges aren’t sealed, fog-belt moisture delaminates the skin from the core. Proper install means sealing every penetration. That’s the part most shortcuts skip.
Winter sticking in San Francisco is usually a temperature differential problem, not a hinge problem. Unheated hallways keep the interior face of the slab cold while afternoon sun warms the exterior face. The slab bows slightly toward the warmer side and starts dragging on the latch side. We fix it by checking slab flatness, adjusting hinge geometry, and in some cases recalibrating the compression seal. Get it looked at before you plane the door, because planing a fiberglass slab is rarely the right answer.
For windy, rain-exposed hillside exposures, we usually recommend either a Smooth-Star fiberglass door without a large glass lite, or a Classic-Craft with a smaller decorative insert set high in the slab. Less glass mass means less hinge loading and fewer seal failures. The frame matters just as much as the slab: we set hillside doors with reinforced bottom sills and compression-grade OEM gaskets, because the wind-driven rain on west-facing hillsides will find any gap at the corners. Call (831) 610-5598 and we’ll walk your specific exposure.
Yes, if the crack is cosmetic and the core hasn’t taken on moisture. We use machined high-grade aftermarket fiberglass repair patches, then color-match the finish. If the delamination covers more than 30% of the door face or the core shows moisture intrusion, we’ll tell you straight: that slab needs replacement. We don’t patch what won’t hold. Call (831) 610-5598 for an on-site assessment.
