Therma-Tru Windows & Doors in San Francisco, CA | Meridian Windows and Doors San Francisco
We provide independent Therma-Tru door service across San Francisco, from the fog-heavy Richmond and Sunset districts to the landmark Victorians near Alamo Square. The thing that makes our Therma-Tru work different here is that we retrofit doors into openings that were framed before 1940, when nothing was square and nothing was standard. That means custom jamb extensions, re-shimmed frames, and weather-sealing built for salt-laden fog, not a showroom floor in Ohio. Call (831) 273-7126 for a free estimate on any Therma-Tru door in San Francisco.
Why San Francisco Residents Choose Us for Therma-Tru Service
Elliot Vance started in this trade with a caulk gun at fifteen, replacing a rotted door frame for a neighbor in the San Gabriel Valley. He did his carpentry training at Los Angeles Trade-Technical College, then spent close to two decades installing and retrofitting windows and doors all over California, including our Window Installation in San Francisco. His crew has worked Victorians near Alamo Square where a 100-year-old frame and a modern fiberglass slab rarely agree on the first measurement. That’s the experience we bring to every Therma-Tru door in San Francisco.
We’re an independent Therma-Tru service provider, not a manufacturer-authorized dealer. That matters because we don’t have a corporate script telling us when to push replacement over repair. If a door’s core is sound, we say so. We use genuine Therma-Tru components when structural integrity matters: full slabs, frames, multi-point locks. But when coastal corrosion is the issue, we machine stainless steel aftermarket hardware rather than reinstall steel that will pit again in two fog seasons. We also carry OEM-compatible weatherstripping, corner seal pads, and threshold flashing for fast turnaround in San Francisco. And our Therma-Tru sales & service work is backed by the 365-Day Done Right Promise, written on every job.
Common Therma-Tru Windows & Doors Problems We Solve in San Francisco
- Fiberglass skin delamination at bottom rails. In the Richmond and Sunset, persistent damp and fog-driven moisture work into the bottom rail through micro-gaps in the corner seal pads. The fiberglass skin starts to peel. We re-skin in place when the core is intact, or replace the slab when it isn’t.
- Warped or swollen door slabs on west-side exposures. Wood-grain fiberglass absorbs condensed fog against poorly flashed thresholds. The slab swells, the door drags, and eventually it won’t latch. We fix the flashing, replace the sweep, and reset the slab so it closes dead-square.
- Failed weatherstripping and corner seal pads on Classic-Craft doors. Victorian-era openings in San Francisco are rarely plumb, which stresses the seals unevenly. You get drafts and visible light gaps at the corners. We replace the pads and install full-perimeter Q-Lon weatherstripping cut to the actual opening, not the manufacturer’s nominal size.
- Corroded hinge screws and adjustment blocks from salt-laden fog. The fog near Ocean Beach carries enough salt to pit standard steel hardware within a few years. Multi-point lock systems are especially vulnerable. We swap in stainless steel hinges, screws, and adjustment blocks so the hardware doesn’t disintegrate before the door does.
- Threshold rot and water intrusion at the base of entry doors. San Francisco’s wet winters and fog drip put constant moisture at the threshold. We replace rotted sub-sills, re-flash the rough opening, and set the new threshold with a slope that sheds water away from the door.
Therma-Tru Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s Article 10 and Article 11 landmark rules often require matching original door proportions and panel profiles when you replace any exterior element on a protected building. That’s true even for doors that aren’t original. So on a Victorian or Edwardian in a landmark district, you can’t just order a standard Therma-Tru Classic-Craft and hang it. The rough opening is too narrow, too tall, or slightly trapezoidal. We retrofit Therma-Tru doors into custom jamb extensions that fit the non-standard opening without altering the exterior trim details that the Planning Department cares about. Measure twice, order once. The window replacement in San Francisco doesn’t care about your schedule, and the landmarks board doesn’t care about your lead time. We have worked enough of these buildings in San Francisco to get the proportions right the first time.
Therma-Tru Models & Products We Service in San Francisco
We service the full residential Therma-Tru line: Classic-Craft Collection, Fiber-Classic, Smooth-Star, and Pulse Series. Most of what we see in San Francisco is Classic-Craft and Fiber-Classic, because those wood-grain slabs match the character of Victorian and Edwardian entries. We stock OEM-compatible corner seal pads, Q-Lon weatherstripping, multi-point lock components, and stainless steel aftermarket hardware locally, so common repairs don’t wait on a freight shipment. When a full slab or frame replacement is needed, we order genuine Therma-Tru components and schedule the install around the delivery.
Therma-Tru Service Pricing in San Francisco
Most Therma-Tru door repairs in San Francisco run between $180 and $650, depending on what’s failing. Replacing weatherstripping and corner seal pads on a Classic-Craft typically falls in the $180 to $320 range. A stainless steel multi-point lock retrofit runs $400 to $700 installed. Full slab replacement, including custom jamb extension for a non-standard Victorian opening, usually lands between $1,400 and $2,800 depending on the model and finish. Every quote is written down before work starts, with line items, so the price doesn’t move at the door. Call (831) 273-7126 for a free estimate. We’ll come out, assess the door, and give you a fixed price on paper.

FAQs – Therma-Tru Windows & Doors in San Francisco
Yes. In most cases, we install Therma-Tru doors into custom jamb extensions that fit the existing non-standard opening, so the original frame and exterior trim stay intact. That’s what the Article 10 and 11 landmark rules care about. We’ve done this on Victorians near Alamo Square and Edwardians in the Haight. Call (831) 273-7126 and we’ll tell you exactly what’s possible for your building.
It will if the installation is done correctly. The fiberglass slab itself is non-porous and won’t rot, but the weak points are the corner seal pads and the threshold flashing. Salt-laden fog in the Richmond and Sunset corrodes standard steel hardware and works moisture through failed seals. We address both at install: stainless steel hinges and screws, full-perimeter Q-Lon weatherstripping, and a properly flashed threshold that sheds fog drip. Call (831) 273-7126 for a free estimate.
We assess the slab core first. If the fiberglass skin is delaminating but the core is sound, we can often re-skin the slab in place and replace the weatherseals. If the core is compromised, we recommend replacing the slab. Either way, we addressed the flashing and drainage at the threshold so the same failure doesn’t come back in two years. On a 1908 Edwardian flat in the Richmond District, we re-skinned a swollen Therma-Tru Classic-Craft door, installed a stainless steel multi-point lock and new Q-Lon weatherstripping, and flashed the threshold to shed fog drip. The door now passes a blower-door test. Call (831) 273-7126 to schedule an assessment.
San Francisco’s building codes don’t require impact-rated doors the way the hurricane coast’s do. What we need here is weather resistance: wind-driven rain, fog, and salt corrosion. We focus on weather-resistance retrofits, stainless hardware, and proper flashing rather than impact glazing. We’ll order an impact-rated Therma-Tru slab if a homeowner specifically wants one, but for most San Francisco properties, the right weathersealing does more good than an impact rating. Call (831) 273-7126 and we’ll spec what actually fits your building.
Yes. The Classic-Craft Collection has wood-grain fiberglass faces with panel profiles that are close matches to original Victorian and Edwardian doors. We work with local finishers who can stain and clear-coat a Therma-Tru slab to the same tone as the home’s original millwork. Matching the proportions matters more than matching the exact panel detail, and we handle that with the jamb extension. Call (831) 273-7126 for a free consultation.
