If you live in San Francisco, you already know the rule: the house was built before your grandfather was born, the bay window hasn’t been touched since the Johnson administration, and the fog is working on your sills even as you read this.

Why San Francisco Homeowners Choose TruePane Windows & Doors
San Francisco is not an easy city to work in, and homeowners here have learned to be careful. Parking is tight. Permit lines at the Planning Department are long. And the housing stock itself, ornate Edwardian flats and Queen Anne Victorians with load-bearing bay assemblies, punishes anyone who treats a window opening like a standard rectangle. We’re known in San Francisco for the jobs other companies walked away from: rotted rough sills in the Richmond, sagging bay window headers in the Mission, double-hung sashes in Noe Valley that hadn’t opened in thirty years.
Dale Kessler founded this company on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. That’s why every quote includes a probe test of the sill and rough sill before we price. That’s why both warranty layers get registered in writing before the truck leaves your driveway. And that’s why, after years of glazier work in the family, we still answer the phone with a person, not a callback form. Homeowners in the Castro and Western Addition call us because they want the work done right the first time, and they want a company that will still be around if something goes wrong. We sponsor county fairs and church roof funds here in the Bay Area because we plan to be in town in thirty years.
Windows & Doors Services We Offer in San Francisco
Window Installation
New window installation in San Francisco almost always means working around historic trim and irregular openings, not clean sheetrock cutouts. We measure every opening twice and set each unit plumb and square, with flashing details that hold up to real fog-driven moisture.
Learn more about our Window Installation in San Francisco.
Door Installation
Entry doors on San Francisco flats have to handle constant wind, sidewalk foot traffic, and decades of settling that leave frames out of square. We hang doors that latch cleanly in January and don’t bind in August, whether you’re replacing a front door on a Victorian in the Western Addition or a rear door off a Noe Valley kitchen.
Learn more about our Door Installation in San Francisco.
Window Replacement
Replacing windows in San Francisco’s older neighborhoods often means matching profiles, preserving exterior trim, and navigating the city’s strict historic preservation rules, which can prohibit vinyl on designated properties. We’ll tell you honestly on the first visit whether your project needs wood, wood-clad, or whether a modern composite line will satisfy both the City and your budget.

Impact Windows & Doors
For San Francisco homes on exposed hillsides or in wind-driven corridors like the Avenues, impact-rated glass adds real protection. We install impact windows and doors from PGT and CGI, registered with both warranty layers before we leave the job.
Energy-Efficient Windows
The marine layer doesn’t just rot wood; it drives heating bills up in these uninsulated old flats. Energy-efficient replacements, including low-E glass and argon-filled units from lines like Ply Gem, cut the draft coming through original single-pane windows that have been rattling since McKinley was in office.
Sliding & Patio Doors
Sliding patio doors in San Francisco take abuse from salt air, fog moisture, and tracks that fill with windblown grit. We replace rollers, realign frames, and install new doors that actually glide, including multi-slide configurations for larger openings on the east and west sides of the city.
Glass Railing Systems
For decks and stairways with views, glass railing systems have to be engineered for wind load and rust resistance, not just aesthetics. We fabricate and install tempered glass railing that holds up to San Francisco’s marine exposure and passes the inspection the first time.
Custom Windows & Doors
Many San Francisco homes have openings you can’t fill with a stock unit, especially those bay windows and French door setups built between 1880 and 1915. TruePane builds fully custom windows and doors sized to the actual opening, including radius tops and matching historic profiles.

Why San Francisco’s Climate & Housing Affect Windows & Doors
San Francisco’s dense stock of Victorian and Edwardian flats, built roughly 1880 to 1915, means the majority of our window and door work involves ornate bay window assemblies and historic wood frames, not simple flat-wall swaps. In the Castro, Mission, Western Addition, and Noe Valley, those protruding bay structures are load-bearing: they carry roof weight and structural loads, and they require custom sizing and specialized flashing work that a standard replacement in a newer city never demands. Then there’s the City itself. The San Francisco Planning Department’s historic preservation rules, and the many designated historic districts throughout the city, effectively prohibit vinyl replacement windows on a meaningful share of jobs in San Francisco. Wood or wood-clad units are often the only compliant option, and we know how to spec those correctly.
The other factor is the fog. The persistent marine layer, especially in the Outer Sunset and Outer Richmond, drives chronic wood rot and paint failure on west- and north-facing frames. Salt-laden air from both the Pacific and the Bay corrodes aluminum hardware and degrades insulated glass seals faster here than in inland cities like Walnut Creek. We’ve learned that original fir window sills can look intact from inside while being completely punky on the exterior face. That’s the slow, cold fog-moisture rot pattern unique to San Francisco’s west side, and it’s why our window quotes always include a probe or awl test of the sill and rough sill before we price. If we don’t test, you don’t know what the job actually costs.
Pricing for Windows & Doors in San Francisco
Honest pricing in San Francisco means accounting for the house before accounting for the window. A standard double-hung replacement in a flat-wall opening typically starts around $900 to $1,600 per window, installed. Bay window assemblies run higher, usually $3,500 to $8,500 or more depending on structural work, custom sizing, and historic district compliance. Entry door replacement in this city generally lands between $1,800 and $4,500. These are ranges, not quotes.

We also offer a free written repair estimate, a maintenance check, and a permanent 5% discount for seniors and veterans.

Yes. We pull permits and pass inspections on every San Francisco job that requires them. You get the paperwork filed and the inspection signed off, and we handle both without you chasing the Planning Department.
No, not on a job we’ve scoped properly. We write a fixed line-item quote after testing your sills and inspecting the rough opening, and we don’t add surprise line items. If structural rot is hidden, we tell you on that first visit, before we’re committed to a number, not after the demo starts. Call (888) 635-0804 for a straight quote.

What San Francisco Customers Say
"Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S.
