Fast, Reliable Custom Windows & Doors Across Mission District

When a Mission District homeowner calls us about a century-old bay window that’s binding, drafty, or showing daylight through the sash, they’re usually not asking whether it can be fixed. They’re asking whether anyone still knows how. We do. Custom Windows & Doors in the Mission means matching original 1910 profiles, rebuilding cantilevered subframes, and specifying glass and hardware that survive the neighborhood’s particular combination of hard sun and salt-tinted marine air. Call (888) 635-0804 and you’ll talk to a person who understands what your flat was built to, not a call center reading from a script.

Why TruePane Windows & Doors Is Mission District’s Custom Windows & Doors Company

We’ve rebuilt enough Mission District bay windows to know that no two on the same block are alike. The Victorians on Guerrero, the Edwardian rowhouses off Valencia, the two-unit flats pressed tight between Dolores and Mission Street, each one carries original millwork cut to a specific hand, not a factory spec. A crew that treats those openings like stock rectangles will underbid the job and then either walk away or butcher the fit. That’s not how we work.

Our crews come from the Bay Area, many of them apprentices Dale Kessler has trained into journeymen over years. They arrive in uniform, background-checked, and they measure every opening twice, on paper, before any number is discussed. When we quote a Mission flat, we quote it for what it actually is: a cantilevered assembly that needs its subframe inspected, its sash profiles custom-matched, and its flashing sealed against both sun-driven shrinkage and nighttime marine moisture. The Done Right Promise sits behind every line item. If the pane is not true, the job is not done.

Our Custom Windows & Doors Services in Mission District

Custom Shape Windows

Mission District bay windows are rarely rectangular. They’re angled bays, radius-topped transoms, and eyebrow arches over entry doors, most cut before 1915. Custom Windows & Doors in Mission District means templating each curved or angled opening precisely, then milling the sash in vertical-grain Douglas fir or genuine mahogany to match the 1-3/8″ profiles original to these buildings. Off-the-shelf will not close the gap, and any contractor who says it will hasn’t looked at your jamb.

Custom Shape Windows

Architectural Grilles & SDLs

Simulated divided lites on a Mission Victorian aren’t decoration, they’re part of the facade’s rhythm. The original front windows on many of these flats carried true divided lites with narrow muntin bars, and when we replace the sash, we match those bar profiles and spacing. Our shop cuts SDLs to the original pattern, whether that’s a 6-over-1 double-hung on a Guerrero Street Edwardian or a paired casement with a transom on a corner flat near 24th and Mission. The grille goes between the glass or on the surface depending on what the original had, and it looks like it belongs there because it does.

Architectural Grilles & SDLs

Oversized Glass Panels

Some Mission properties have been reworked over the decades with larger openings, storefront-style glazing, or modern additions that break from the Victorian mold. We handle oversized glass units for those jobs, including insulated low-E units up to 50 square feet or more, delivered and set with the right equipment for tight Mission streets. Parking a crane on a narrow block off Bryant takes coordination, and we’ve done it enough to know which corners actually work. Every oversized panel is specified for structural wind load and the Mission’s heat gain profile, not just dropped in to fill a hole.

Oversized Glass Panels

Commercial Storefront Glazing & Curtain Wall Systems

The Mission District carries a busy commercial strip along Mission Street, 24th Street, and into the BART-adjacent corridors, and storefront glazing here deals with the same sun load as the residential stock plus heavy foot traffic and more vandalism exposure. We install and replace aluminum storefront systems, curtain wall sections, and entry doors for Mission storefronts and mixed-use buildings, specifying laminated glass and thermally broken frames where code calls for them. Curtain wall work on older Mission structures often requires engineering review of the existing opening, and we pull that in before we cut the first mullion.

Trusted Brands We Service in Mission District

We’re an authorized installer for more than a dozen manufacturer lines, and for Mission District jobs we lean on a few workhorses. ES Windows gives us the custom wood and wood-clad profiles that match Victorian and Edwardian sash work, CGI and CWS supply impact-rated systems when a flat faces an unprotected exposure, and ECO Window Systems covers energy-efficient aluminum and vinyl lines for rear additions and rental unit replacements where budget matters more than period detail. We quote these lines side by side on paper, so you see exactly what each manufacturer offers and what the warranty terms actually say. Both warranty layers get registered in writing before our truck leaves your driveway.

Common Custom Windows & Doors Problems We See in Mission District Homes

  • Sun-dried sash rot in cantilevered bays. Twin Peaks blocks the marine layer, so south-facing Mission windows bake in sun the Sunset never gets. The wood shrinks, the old glazing putty cracks, water wicks into the end grain, and the bottom sash rails rot quietly behind the paint. We find this on nearly every original bay we open.
  • Cycling gaps and failed insulated glass. Mission flats warm up hard during the day and cool fast at night with salt-laden moisture in the air. That daily expansion and contraction cycle breaks older insulated glass seals faster here than in foggy districts, leaving fogged panes in windows less than fifteen years old.
  • Improper flashing from previous replacements. Tight rowhouse spacing tempts crews to reuse old flashing tape and skip the cantilever’s structural load path. The result is moisture trapped behind the jamb, hidden rot inside the wall, and a window that looks fine for six years and then fails all at once.
  • Non-standard dimensions that defeat stock replacements. Original Mission sash openings were built to hand-cut dimensions, not modern factory increments. A stock window jammed into a 118-year-old opening leaks air, binds the sash, and costs more to correct later than a proper custom fit would have cost up front.

Pricing for Custom Windows & Doors in Mission District, CA

What you pay in Mission District depends on which opening we’re talking about and what condition the surrounding framing is in. A straightforward custom wood sash replacement for a single Victorian double-hung runs $1,800 to $3,400 per window, including sash matching, low-E glass, and marine-grade flashing. A full cantilevered bay rebuild with new sash, subframe repair, and stainless hangers runs $7,500 to $15,000 for a typical three-sided bay. Oversized glass panels start around $900 for a modest fixed unit and climb to $2,400 or more for large insulated low-E panels with structural requirements. Architectural grilles and SDLs add $300 to $850 per window depending on profile complexity. These are real Mission numbers, not a national average. Call (888) 635-0804 and we’ll measure, inspect, and put a written line-item quote in your hand. The estimate is free.

The Mission District Problem: Salt Air Decides the Materials, Not the Schedule

On a repaint of a 1905 Edwardian flat on Guerrero Street, our crew pulled a cantilevered bay window and found the bottom sash rails had rotted where original glazing putty had failed. Not from fog, but from years of direct Mission sun shrinking the wood, then wicking in moisture from the salt-tinted marine air. We matched the custom 1-3/8″ thick sash profiles in vertical-grain Douglas fir, rebuilt the rotted cantilever subframe with pressure-treated lumber and stainless steel hangers, and reinstalled double-hung sashes with low-E glass and marine-grade flashing tape before a full exterior paint. That job is still tight today.

Unlike fog-bound Sunset or Richmond, Mission District’s Victorian bay windows face intense sun exposure because Twin Peaks blocks the marine layer, causing century-old wood sashes to crack and gap faster. So replacement frames here must be specified for both UV stability and salt-air moisture, a dual threat no neighboring microclimate combines the same way. It’s not an academic distinction. A window specified for inland heat will work fine for five or six years on a Mission south wall, then the unsealed end grain starts drinking marine air and the rot begins. The coastal-spec version costs 15 to 25 percent more on the day of install because you’re paying for stainless jamb hardware instead of zinc, marine-grade flashing instead of standard tape, and UV-stable polyurethane millwork instead of a basic pine jamb. Over ten years, the cheap spec costs more. You replace it twice and repair the wall behind it. We quote the coastal spec because the Mission is a coastal place, even when the sun says otherwise.

What Mission District Customers Say

Trusted by homeowners across Mission District and surrounding areas.

★★★★★

"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. · Verified customer
★★★★★

"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."

Gene A. · Verified customer
★★★★★

"Two entry doors. Showed up when they said, second day was a half day like they said, and the painter they recommended confirmed the frames were dead plumb. The financing was explained in actual dollars, not a brochure."
