AfterTherma-Tru Construction in San Francisco, CA | Rowan Construction Group
Rowan Construction Group provides independent Therma-Tru door service across San Francisco, from slab swaps in original Victorian frames to full pre-hung replacements after seismic work, and Therma Tru repair in Oakland as well. The thing that separates our Therma-Tru work here from any other market: we know whether your job lands in the SF Department of Building Inspection’s over-the-counter lane or triggers a full plan check, and we quote it accordingly. We are not an authorized Therma-Tru dealer, and we do not pretend to be. We are a construction contractor that works on these doors every week in this city’s oldest housing stock. Call (470) 298-9650 for a written quote before anyone picks up a tool.
Why San Francisco Residents Choose Us for Therma-Tru Service
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent two decades working residential and light commercial projects across California. What that means for your Therma-Tru door is simple: we measure the rough opening, check the frame for racking from past seismic movement, and tell you what the easiest correct fix is, not the most expensive one.
San Francisco’s Victorians and Edwardians rarely have square openings anymore. A 1905 flat near Alamo Square might have shifted a quarter inch since the Loma Prieta quake, and a pre-hung door installed without accounting for that will bind at the latch within a year. Our crews have replaced enough Therma-Tru Fiber-Classic and Smooth-Star units in this city to know when a door is worth saving with a new slab, hinges, and weatherseal, and when the frame has gone too far. We stock common Therma-Tru replacement slabs and genuine hinges locally, and a live person answers our phone around the clock, which matters when a warped entry door is letting fog drip onto your oak flooring in the Outer Richmond.
Common Therma-Tru Construction Problems We Solve in San Francisco
- Swelling and sticking in fog-heavy neighborhoods. In the Sunset and Outer Richmond, marine fog keeps humidity high from May through August. Therma-Tru doors, like any wood-fiber or composite door, respond to moisture. When a Fiber-Classic Mahogany slab absorbs enough ambient damp, it expands just enough to drag on the threshold. The fix is usually a weatherseal adjustment and re-shimming, not a new door. We see this every summer.
- Frame racking after soft-story retrofit work. When a multi-unit building goes through the mandatory Soft-Story Retrofit Program, the framing loads shift. Door frames that were square before the retrofit can end up 3/8 inch out of plumb. A Therma-Tru door in a racked frame will not close cleanly, and forcing it wears the hinges. We reset the frame or install adjustable hinges and a Tru-Defense weatherseal kit, then get the door past the DBI’s post-retrofit inspection without re-opening plan check.
- Rot at the bottom rail from chronic fog and rain intrusion. San Francisco gets sideways rain in the winter. When a threshold has worn flat or the sweep has failed, water sits at the base of the door and wicks into the slab. We replace the threshold and sweep with current Therma-Tru weatherseal components before the rot spreads to the interior flooring.
- Warped Fiber-Classic slabs on south-facing exposures. San Francisco’s microclimates mean a door near Dolores Park gets real sun while a door three blocks west might not. South-facing Therma-Tru Fiber-Classic doors in the Mission can warp when one side of the slab heats unevenly. A replacement slab with a lighter finish, or adding a storm door, solves this. We check the exposure before recommending a finish.
- Antiquated hardware on Tru-Defense doors. Tru-Defense units have a continuous compression weatherseal system. When the door is older, the seals flatten and lose compression, and the multi-point lock can fall out of alignment. We replace the weatherseal kit and service the lock mechanism, which costs far less than a new door.
BeforeAfterTherma-Tru Service in San Francisco: What Local Conditions Mean for Your Equipment
Here is something that sounds like inside baseball but decides whether your door job takes an afternoon or eighteen months: San Francisco’s DBI requires any exterior door replacement on a building over 50 years old to go through a site permit only if the opening itself is altered. A like-for-like Therma-Tru slab swap in an existing frame, where the rough opening size does not change, stays over-the-counter. That distinction saves clients months of waiting and thousands in review fees, and it matters most on soft-story retrofit projects. If your building near the Marina or South of Market sits on bay fill, the retrofit scope can already include foundation and shear wall work; the last thing you want is a door trigger pulling the whole job into full discretionary plan check. A contractor who does not know that San Francisco distinction will pad the timeline and the price. We scope the door against the DBI’s actual triggers on the first site visit, not after the demo starts.
Our crew replaced a warped Fiber-Classic Mahogany entry door on a 1905 Edwardian flat near Alamo Square after the soft-story retrofit shifted the frame by 3/8 inch. We used a new Therma-Tru slab with adjustable hinges and a Tru-Defense weatherseal kit, resetting the threshold to meet the DBI’s post-retrofit inspection without a full plan-check resubmittal. The client got a door that closes properly, and the building passed inspection. That is the level of local knowledge you are paying for.
Therma-Tru Models & Products We Service in San Francisco
We work on all four of the main Therma-Tru lines: Fiber-Classic Mahogany Collection, Smooth-Star, Pulse, and Tru-Defense. For Fiber-Classic and Smooth-Star, we source genuine Therma-Tru replacement slabs, hinges, and weatherseal kits when the existing frame is sound and square. For older units no longer supported by current part codes, we use quality aftermarket threshold and sweep components, and we tell you that is what we are doing before the quote, with the part name on it. When a door has significant frame rot, or the frame has moved from seismic work, we recommend full frame-and-slab replacement over patch repairs. We do not patch a racked frame. It will fail again, and you will have paid twice. Our product coverage extends beyond doors too. For clients adding a new Therma-Tru patio door as part of a Therma-Tru sales & service scope, we coordinate the rough opening sizing with the rest of the structural work.
Therma-Tru Service Pricing in San Francisco
Pricing on Therma-Tru work in San Francisco is driven by three things: whether the frame is salvageable, whether the opening is being altered, and the condition of the surrounding structure. A slab swap in an over-the-counter frame is a few hours of labor. A full pre-hung replacement with new weathering, hardware, and trim on a building that needs a site permit is a different job. Here are the line items we quote most often, in dollars, so you can screenshot and compare:
| Service | Price Range |
|---|---|
| Therma-Tru entry door slab replacement (labor only, frame intact) | $945-$2360 |
| Full pre-hung Therma-Tru door replacement including weathering and hardware | $2950-$5900 |
| Kitchen remodel including new Therma-Tru patio door opening | $16520-$53100 |
A free estimate includes a written flat price, a written scope, and a written warranty. Clause 1 of the Haven Standard is the whole point: the price is on paper before any work starts. Call (470) 298-9650 and we will tell you whether your door is an over-the-counter morning or a plan-check project, before you spend a dollar.

FAQs - Therma-Tru Construction in San Francisco
Only if you alter the rough opening or the building is over 50 years old and the door location changes structurally. A like-for-like slab swap in an existing frame stays over-the-counter. We confirm the exact trigger on the first site visit based on your building’s age and the opening dimensions. Call (470) 298-9650 and we will tell you which lane your door lands in, with the DBI requirement cited.
Yes. San Francisco’s Victorians and Edwardians have fir and redwood trim profiles you cannot buy off the shelf at a big-box store. We mill matching profiles from the same species when the original is too far gone to reuse. The quote includes the trim match separately so you see what you are paying for.
Marine fog keeps ambient humidity high, and the fiber-composite slab absorbs moisture and expands slightly. The door typically needs a weatherseal adjustment, re-shimming, or a threshold reset. It rarely needs replacement. We see this pattern every summer in the Outer Sunset and Outer Richmond, and the fix is usually under $400 before labor.
Yes. When a building goes through the mandatory Soft-Story Retrofit Program in San Francisco, door frames shift as the new shear walls tighten up. We install Therma-Tru units after the structural work is complete, or reset existing units that were knocked out of square. The door has to pass the DBI’s post-retrofit inspection along with the rest of the work, and we make sure it does.
A slab-only replacement with the frame intact runs $945-$2360. A full pre-hung replacement including weathering, hardware, and trim runs $2950-$5900. The final number depends on whether the opening is altered and whether the building triggers a site permit. Call (470) 298-9650 for an exact written quote, free.
