Therma-Tru Construction in Mission District, CA | Framework Contractors
We provide independent Therma-Tru service across the Mission District, from entry door replacements to full ADU and addition work where a Therma-Tru unit is part of the plan. What makes our Therma-Tru work different here is that we understand how these doors behave when they’re set into hundred-year-old Victorian and Edwardian openings that have been re-framed, shimmed, and retrofit more times than anyone can count. Framework Contractors is not authorized, sponsored, or endorsed by Therma-Tru. We’re a licensed Mission District General Contractor who installs, services, and repairs their products because Mission District homeowners ask for them by name. Call (844) 681-3590 for a free estimate.
Why Mission District Residents Choose Us for Therma-Tru Service
We know Therma-Tru doors the way a mechanic knows a specific engine. Fiber-Classic slabs, Smooth-Star skins, Classic-Craft raised panels, prehung patio and sidelite units. We’ve set them into soft-story Victorians on Shotwell, Edwardians on Guerrero, and post-1950s infill on Capp Street. The difference between a door that closes clean for a decade and one that starts dragging in November is almost always what happens at the rough opening. In the Mission District, rough openings are never square and rarely original.
Noel Carbajal grew up patching stucco and reroofing porches with his uncle in Santa Ana, then studied Construction Technology at Santiago Canyon College. Thirty years later, he’s still the one who walks every job before a single hinge comes off the truck. His approach on Therma-Tru work is simple: fix the opening, flash the sill, use OEM parts where the frame is sound, and don’t sell a replacement when a repair will outlast the mortgage. This is a Therma-Tru sales & service page we wrote for people who want specifics, not a sales pitch.

Common Therma-Tru Construction Problems We Solve in Mission District
- Moisture-wicking at bottom rails and sill ends. When a prehung Therma-Tru unit gets set over a garage-grade concrete stoop without pan flashing, the constant Mission fog keeps that joint damp year-round. The fiberglass skin blisters or delaminates at the base, and the sill end softens until it can’t hold the sweep. We see this on nearly every original-ground-floor entry between 24th Street and Cesar Chavez. Fix: open the rough opening, rebuild the sill detail with pan flashing, install OEM sill and sweep, re-hang the slab.
- Hinge-side sag in out-of-plumb balloon-frame jambs. Old Victorian openings shift seasonally as the framing swells with winter damp and dries in the September heat. Doors start dragging, strike plates miss by a quarter inch, and weatherstrip gaps open along the latch side. A new door won’t fix this. Square the opening and re-shim first.
- End-of-life builder-grade doors in post-1950s infill. Blocks of denser Mission District infill built after 1950 are hitting the point where original steel and fiberglass slabs are chalked, dented, and leaking wind-driven rain past dead sweeps. When we replace these, we’re usually replacing a whole generation of doors on the same street within a few years of each other.
- Weatherstrip and corner-seal failure around sidelites and glass lites. Fog-belt damp gets into the frame cavity wherever seals break down. That moisture rusts hinge screws and strike hardware from the inside. On Therma-Tru units with sidelites or decorative glass, this is the most common call we get between December and April.
- Racked slabs after soft-story retrofits. This one is uniquely Mission District. When the ground-floor garage gets opened up for seismic shear-wall work, the entry rough opening often moves slightly. A door that closed fine for years suddenly drags. We fix the opening and the door together, on the same permit set.
Therma-Tru Service in Mission District: What Local Conditions Mean for Your Equipment
Under San Francisco’s Mandatory Soft Story Retrofit Ordinance, the ground-floor garage at the base of nearly every bay-windowed Victorian in the Mission District is being opened up and re-framed. That work routinely reshapes the very entry and garage-door rough openings a Therma-Tru unit has to sit in, so the door spec and the seismic detailing are decided together on the same permit set. This is not true in Noe Valley, where the housing stock is younger and soft-story work is less concentrated. Here, you can’t spec a front door as a standalone item. The shear-wall contractor’s rough framing and the finish carpenter’s door installation have to coordinate, or the door ends up racked and the DBI inspector flags the final.
On a bowed-front Edwardian off Valencia Street, our crew opened the ground-floor garage for a soft-story retrofit and found the entry opening had already been re-framed twice. A Therma-Tru Fiber-Classic slab was so racked it dragged across the threshold, and its sill end had rotted clean through. We re-squared the rough opening, rebuilt the sill with pan flashing and Therma-Tru OEM weatherstrip, re-hung the prefinished unit, and tied the head flashing into the new shear-wall work. Door and seismic detail closed out on the same DBI inspection. That’s the job, every time, in the Mission District.
For homeowners in the broader Mission District service area we cover, this means your door quote has to account for what’s happening behind the jamb, not just the slab.
Therma-Tru Models & Products We Service in Mission District
We work on the full Therma-Tru entry lineup: Fiber-Classic fiberglass doors, Smooth-Star smooth fiberglass slabs, Classic-Craft series doors with their raised-panel look, and prehung patio and sidelite units. Our repair stance is simple. Use Therma-Tru OEM sills, sweeps, weatherstrip, and hinge hardware wherever the frame is still sound. Only go to quality aftermarket weatherseal when an OEM profile has been discontinued. Most Mission District failures start at the sill and rough opening, not the slab itself. So we fix the opening and flashing detail first, and recommend a full replacement only when the skin or frame is structurally finished. Replacement work often rides alongside our Home Remodeling in Mission District, including broader window replacement, home addition, and ADU construction scopes.

What drives the cost on a Mission District Therma-Tru job is rarely the door. It’s the opening. Re-squaring a balloon-frame jamb, rebuilding a rotted sill, flashing a garage-grade stoop, and tying the head detail into shear-wall work all add labor that a clean suburban rough opening would never need. A free estimate from us includes a full look at the opening, the sill, the flashing, and the existing frame condition. Not just the slab. Call (844) 681-3590 and we’ll walk the site with you.

FAQs – Therma-Tru Construction in Mission District
Yes, and this is where it makes the most sense. Since the ground-floor garage and entry are already being opened up for seismic work under the city’s Mandatory Soft Story Retrofit Ordinance, adding or replacing a Therma-Tru entry door as part of that same permit set is faster and cheaper than doing it as a separate project later. The rough opening gets framed to the right spec, the flashing goes in with the shear-wall work, and the door closes out on the same DBI inspection. Call (844) 681-3590 if you’re already pulling a retrofit permit, we’ll spec the door to match the structural drawings.
In the Mission District, it’s almost never the door. It’s the balloon-frame wall behind it. The old growth softwood in Victorian and Edwardian jambs swells with winter damp and moves the opening out of square. When the frame shifts, the door drags. This gets worse after a soft-story retrofit if the shear-wall sequencing shifted the opening. We re-square and re-shim the rough opening before touching the door, and on most jobs the original Therma-Tru slab goes right back in and closes clean.
It depends on the scope. A direct door replacement in an existing opening often proceeds as a repair, but once you alter the rough opening, add sidelites, or tie into a soft-story retrofit, the DBI will want it on the permit set. We handle that coordination with the Planning Department and DBI as part of any job. When in doubt, assume the permit is required. It usually is.
Fiberglass holds up better than steel on a Mission District entry that eats fog nine months a year. The Therma-Tru Fiber-Classic line resists the blistering and delamination we see on older steel slabs at sill level, and it takes a paint-grade finish that matches Victorians well. The key isn’t the door though. It’s the pan flashing under the threshold and the sill detail. Any door we install here gets a fully flashed and sealed rough opening, regardless of the model.
Yes, and we do this regularly. The Therma-Tru Classic-Craft series offers the kind of raised panel profiles and glass lite configurations that read correctly on an Edwardian facade. We match the panel geometry, the finish, and the hardware set to the original, or to whatever remains of it. But we’ll be straight with you: on a hundred-year-old opening, matching the look is the easy part. The harder part is building the rough opening so the new door doesn’t inherit whatever made the old one fail. Call (844) 681-3590 to talk through your entry.
