Why San Francisco Homeowners Choose Therma-Tru Construction
We provide Therma Tru in San Francisco door construction, repair, and installation service throughout the city, from the Richmond to the Marina to the Outer Sunset. We’re not a Therma-Tru authorized dealer, and we won’t pretend to be. What we are is a remodeling contractor that works on Therma-Tru Fiber-Classic, Smooth-Star, Pulse, and Benchmark doors every week, usually while we’re already inside a house rebuilding a kitchen or bath. That puts us in a position most door-only shops never reach: we catch framing problems, fog-driven moisture damage, and threshold failures before they become full slab replacements.
If you have a Therma-Tru door that’s dragging, sticking, leaking air, or showing bubbles at the bottom rail, call Bradford Remodeling Co San Francisco at (831) 610-5598. Curtis Lane and our crew will give you a straight number, a written scope, and a decision: repair what’s fixable, replace what isn’t. No warranty script, no upsell.
Why Trust Bradford Remodeling Co San Francisco for Your Therma-Tru Construction?
Our crews know these doors because we’ve pulled enough of them apart to see exactly how they fail in San Francisco’s marine air. A Therma-Tru Fiber-Classic door installed in the Outer Sunset doesn’t behave like the same door installed in Walnut Creek. The fog carries salt and moisture that works into weatherstripping channels, swells wood jambs, and accelerates rust on metal hinge leaves. Curtis Lane learned this the hard way during a stretch of gut-and-rebuild projects in the Outer Sunset, where fog-driven moisture moves through older balloon-frame walls in ways that surprise Therma Tru service in Oakland contractors. That experience is why we check the rough opening, not just the slab, on every Therma-Tru service call.
Every Therma-Tru job we take gets a written price before any work begins, per The Garrison Standard that Bradford Remodeling Co San Francisco has operated under since 2004. Every completed project carries the 365-Day Done Right Promise: if our Therma-Tru repair or installation fails within a year, we return and correct it at no charge. That guarantee is in writing, in your hand, at job close. The site is clean, the scope is documented, and there are no numbers that move at the door. Straight number, real scope, no surprises at close-out.

Common Therma-Tru Construction Problems We Fix in San Francisco
- Warped or swollen slabs on Fiber-Classic and Smooth-Star entry doors. West-facing exposures in the Richmond and Sunset take the brunt of afternoon fog and wind. When compression weatherstripping fails or a door sweep wears down, moisture settles into the bottom rail. Fiberglass skins don’t rot like wood, but the internal stile and rail cores can swell enough to make the door bind against the jamb in winter and drag across the threshold in summer. We diagnose whether it’s a moisture issue, a settled rough opening, or a hinge problem before recommending anything.
- Failed compression weatherstripping causing visible daylight at the threshold. Therma-Tru’s compression seal system is effective, but the seals are wear items. On older Fiber-Classic doors, the bulb seal flattens over time, and once you can see daylight under the door, you’ve lost the air seal. In San Francisco, that means bay wind and fog get a direct path into the front hall. We replace with OEM Therma-Tru compression seals when tolerances require it, and quality aftermarket sweeps or thresholds where they’ll seal better and last longer.
- Rusted or seized hinges on Benchmark by Therma-Tru steel frames. Benchmark is Therma-Tru’s value steel and fiberglass slab line, and in San Francisco’s marine air, the steel hinge leaves on Benchmark frames corrode faster than on residential fiberglass lines. We see seized pins, creased hinge leaves, and stripped screw holes where rust has compromised the frame. A door that won’t swing smoothly is a security issue and a seal issue. We replace hinges with stainless or corrosion-resistant options where the original spec failed.
- Delaminated fiberglass skin bubbling at the bottom rail. This is the most common terminal failure we see on older Therma-Tru doors in fog-heavy neighborhoods. The fiberglass skin separates from the core at the bottom rail, usually because a missing or worn door sweep allowed standing moisture to sit against the door. Once the skin delaminates, the door is compromised. We’re honest about this: sometimes a new fiberglass unit with fresh seals costs less than chasing repeated seal failures on a compromised slab.
- Settled rough openings on older Victorian and Edwardian homes. San Francisco’s housing stock moves. A century of seismic shifts and adobe clay soil settling means the rough opening that fit a door perfectly in 1920 may be 3/8 inch out of square today. We rebuild jambs, shim openings level and plumb, and rehang the door so the slab seats evenly against the weatherstripping. Skip this step and any new door will bind, leak, or warp within a season.
Therma-Tru Parts & Our Repair-vs-Replace Approach
We use OEM Therma-Tru hinges, weatherstripping, and compression seals whenever lead times allow. Therma-Tru’s tolerances are tight, and aftermarket parts sometimes don’t seat properly in the milled channels. But when an OEM seal is two weeks out and your front hall has a cold draft in January, we’ll install a quality aftermarket threshold or sweep that seals correctly today, and we’ll tell you exactly what we did and why. No surprises, no gotchas.
Our decision rule is simple: repair what’s fixable, replace what’s compromised. A hinge, a sweep, a threshold, a jamb repair – those are repairs. A delaminated fiberglass skin, a slab warped more than a quarter inch, or a Benchmark steel frame rusted through at the hinge – those are replacements. We’ll show you the failure, explain the trade-off, and give you a written price for both paths when both are viable. If a repair will fail within two years, we’ll tell you that too. Call (831) 610-5598 for an honest assessment.
Our Therma-Tru Service Process – Step by Step
- 1
Diagnosis. We inspect the slab, hinges, weatherstripping, threshold, and rough opening. On older San Francisco homes, we check for settlement in the opening itself, because that’s what fails first on Victorians and Edwardians. We test the seal with a feeler gauge and check for daylight at the threshold.
- 2
Written scope and price. Before any work starts, you get a written line-item quote covering parts, labor, and any jamb or rough opening repair. No numbers move at the door. This is The Garrison Standard, applied to every Therma-Tru job.
- 3
Repair or replacement. We execute the work with OEM Therma-Tru parts where spec matters – hinges, compression seals, weatherstripping – and quality aftermarket components where they’ll outperform or outlast the original. Minor jamb repairs and rough opening corrections happen in this stage.
- 4
Testing and adjustment. We hang the door, shim as needed, and test the full seal envelope: top, sides, threshold. The door should close without force, seal evenly, and latch cleanly. If it doesn’t, we adjust until it does.
- 5
Documentation and warranty. You get a written scope of work, a copy of the parts used, and the signed 365-Day Done Right Promise. We walk the site, confirm it’s clean, and make sure you know exactly what was done and what’s covered for a full year.

AfterTherma-Tru Products We Service & Install in San Francisco
We service and install across the Therma-Tru residential lines you’ll actually find in San Francisco homes. That includes Fiber-Classic Entry Doors – the most common line in Victorian and Edwardian remodels, with the wood-grain fiberglass look and the most predictable failure modes in fog; Smooth-Star Entry Doors, the smoother-faced fiberglass line that performs similarly but has different skin and finish characteristics; Pulse Entry Doors, the contemporary line with clean lines and modern glass options; and Benchmark by Therma-Tru, the value steel and fiberglass slab line that shows up on rental units, garages, and budget remodels. We keep common weatherstripping profiles, threshold caps, and hinge sets in our local inventory for faster turnaround on standard service calls.
We Also Service These Brands
Therma-Tru is one brand we know deeply as a General Contractor, but it isn’t the only one. Bradford Remodeling Co San Francisco works with KraftMaid cabinetry, Cambria and Silestone surfaces, and Kohler fixtures among others, which matters when a door installation is part of a larger kitchen or bath remodel. One crew, one written scope, one guarantee covering the whole project.
FAQs – Therma-Tru Construction Service in San Francisco
Winter sticking is almost always a moisture and humidity issue, not a structural failure. San Francisco’s winter fog and rain raise the moisture content of the wood jamb and, in some cases, the internal stiles of the door. The door expands just enough to bind against the jamb. It can also be a settled rough opening that tightens as the surrounding framing shifts in wet soil. We diagnose the cause before recommending a fix; sometimes it’s a simple hinge adjustment and weatherstripping replacement. Call (831) 610-5598 and we’ll tell you what’s actually going on.
Yes. Compression weatherstripping is a replaceable wear item, and on most Fiber-Classic and Smooth-Star doors, we can pull the old seal and install a new OEM Therma-Tru compression seal or a quality aftermarket equivalent without touching the slab. If the channel itself is damaged or the door has settled, we’ll address that too. The job usually runs in the $470 to $2,125 range depending on how many sealing surfaces need work. Call (831) 610-5598 for an exact written quote.
In most cases, yes. Once the fiberglass skin separates from the core at the bottom rail, the door’s structural integrity is gone. You can patch it cosmetically, but the patch will fail again, usually within a season or two in San Francisco’s fog. A new fiberglass unit with fresh compression seals and a proper door sweep often costs less than repeated seal and patch work over three years. We’ll show you the delamination and quote both paths where viable. Call (831) 610-5598 for an honest assessment.
The steel frames and hinge leaves on Benchmark doors are more vulnerable to corrosion than Therm-Tru’s fiberglass lines, especially within a few blocks of the bay or ocean. Salt-laden fog gets into hinge seams, and once rust starts, it spreads. We replace rusted hinges with corrosion-resistant stainless options and can treat early rust on frames before it compromises the hinge mounts. If a frame is rusted through at the hinge, replacement is the only durable fix. Call (831) 610-5598 for an evaluation.
Yes, within reason. Therma-Tru’s product lines have evolved, and a 20-year-old Fiber-Classic door may not have an exact current equivalent in grain pattern and finish. But we can usually match the panel profile, glass configuration, and trim treatment closely enough that the doors read as a matched set from the street. We’ll bring samples and show you the closest current Therma-Tru options, along with what won’t match perfectly and why. Call (831) 610-5598 to schedule a walk-through.
