AfterWindows & Doors in Mission District, CA
Window installation and replacement in the Mission District is dominated by one fact: most flats here were built between 1880 and 1920, and their original single-pane wood sash is often integral to the building’s bay framing. Add the neighborhood’s protected “banana belt” sun exposure and you get a specific failure pattern: south- and west-facing wood rots faster than foggier parts of San Francisco, while overnight marine moisture still works its way into century-old glazing. If you want a written price before any tool is lifted, call (509) 265-6387.
Why Mission District Homes Are Different
The Mission District’s 2-4 unit Victorian and Edwardian flats present challenges you won’t find in Daly City or even the Outer Sunset. The iconic canted bay windows that define these facades were often built as structural cantilevered assemblies tied directly into floor framing. That means what looks like a straightforward sash swap can require a structural engineer’s sign-off and a full permit set through San Francisco’s DBI review process. Contractors who don’t expect that get caught mid-job, and the homeowner pays for the delay.
Shared party walls between rowhouses limit lateral egress options and make door rough-opening modifications structurally sensitive. Add the Mission’s unique microclimate, shielded from coastal fog by Twin Peaks and getting meaningfully more UV and afternoon heat than the Richmond, and you have paint failure and wood-frame rot accelerating on exposed elevations. Yet the overnight marine layer still condenses against old single-pane glass. It’s a two-front war on window envelopes, and we treat it that way on every survey.
Our Main Mission District Services
Most Mission District homeowners reach out to us about two jobs: a door that no longer closes square in a settling Victorian frame, or a window replacement complicated by period millwork and DBI permit requirements.
Door Installation in Mission District
Heavy wood entry doors on Mission District flats are often original to the building, meaning 110-plus years of seasonal movement, paint buildup, and hinge wear. Installing a new door here isn’t a simple slab swap; it usually means re-machining hinge mortises in a shifted frame, accounting for out-of-square rough openings, and matching period trim profiles so the entry doesn’t look like a patch. We handle the full scope, from measured survey to final photo record. Door Installation in Mission District covers the specifics.
Window Replacement in Mission District
Replacing windows in a Mission District Victorian or Edwardian often means working inside the city’s preservation review process, which can require custom-milled wood sash matching the original profile rather than off-the-shelf vinyl or aluminum. The canted bay windows on many of these buildings are structural, not decorative, so engineering sign-off is common. Window Replacement in Mission District walks through the process and what to expect from DBI.

BeforeAfterWindow Installation in Mission District
Installing new windows in Mission District flats means working within a set of constraints that don’t exist in most nearby neighborhoods: original wood sash that may be structurally tied to bay framing, DBI permit timelines, and sun-driven wood rot on exposed elevations. Most jobs start as a replacement of failing single-pane double-hungs or hopper sash, then expand once the measured survey reveals what’s behind the trim. Our Window Installation process always begins with a written survey the homeowner keeps.
Single & Double Hung Windows
Signs you need it
Sash that won’t stay open, visible rot at the meeting rail, or glass that sweats between the panes.
What it costs in Mission District
Plan on $240 to $520 per opening for labor and standard sash, with period-profile millwork adding to material cost.
How we do it
We measure the existing sash, specify the replacement to match sightline and profile, remove the old unit, install and seal the new one, then leave a documented photo record.
Casement Windows
Signs you need it
Crank mechanisms that bind, sash that drops when open, or visible daylight at the weatherstripping.
What it costs in Mission District
Expect $400 to $960 per unit installed, depending on size and whether the jamb needs rebuild work.
How we do it
We survey the existing rough opening, specify the crank or push-out hardware, remove the old sash and frame, install and level the new unit, and seal the exterior per SF code.
What Window Installation Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Single or double hung window (standard size) | $240 - $520 per opening |
| Casement window | $400 - $960 per unit |
| Custom-milled sash matching original profile | $350 - $800 per window added |
Does window installation in Mission District require a permit?
Yes, in most cases. San Francisco DBI reviews window work on older buildings, and the canted bay windows on many Mission District flats are structural, which can require an engineer’s sign-off. We handle the permit drawings and submittals as part of the written scope.
How long does window installation take in Mission District?
Standard single-hung or casement replacement runs one to two days per opening once the permit clears. Period millwork and structural bay work can add two to four weeks for fabrication plus review time. Your written quote will fix the schedule.
Impact Windows & Doors in Mission District
Impact-rated glazing in Mission District flats is a different conversation than in South Florida, because the driver here is not hurricane code but structural robustness on canted bay assemblies and the area’s stronger afternoon UV load. Laminated impact glass also quiets Dolores Street bus traffic and Valencia corridor noise in ways that standard double-pane won’t. Our Impact Windows & Doors line includes PGT and CGI products specified by opening, not margin.
Impact-Resistant Windows
Signs you need it
You want glass that holds its shape if struck, or you’re replacing windows in a building where the bay assembly needs the added stiffness of laminated glazing.
What it costs in Mission District
Budget $650 to $1,400 per window installed for impact-rated laminated units, with structural bay work priced separately.
How we do it
We survey the bay assembly, specify the correct impact-rated laminate thickness, replace the sash and glazing, and document the installed product tags for your records.
Double Hung Impact Windows
Signs you need it
You have original double-hungs that face south or west, and the single-pane glass is failing while the wood frame is still structurally sound.
What it costs in Mission District
Expect $720 to $1,500 per opening for impact-rated double hung windows in period-appropriate profiles.
How we do it
We fabricate or order the specified sash, remove old units, install new impact glazing in the existing frame where allowed, or install a full new frame, then seal and document the job.
What Impact Windows & Doors Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Impact-resistant window (standard size) | $650 - $1,400 per window |
| Double hung impact window | $720 - $1,500 per opening |
| Impact-rated door (entry or garden) | $1,400 - $2,900 per door |
Will impact windows look different from my original Mission District sash?
Not if specified correctly. We order impact-rated units milled to match the original sightline and profile, so the glass thickness is the only visible difference, and even that is subtle at typical viewing distance.
Do I need impact windows in San Francisco?
Not by code in the Mission District, but many owners of canted bay windows choose them for the structural stiffness and the urban noise reduction on Valencia Street or Mission Street frontages. Call (509) 265-6387 to talk through whether it makes sense for your building.
Energy-Efficient Windows in Mission District
Energy-efficient windows in Mission District flats are a specific proposition: you’re replacing single-pane wood sash from the 1880s to 1920s, and the sun side of your building gets real heat load while the shaded side stays damp and cool. Low-E coatings and argon gas do the most good on south- and west-facing bays. You’ll find the full spec breakdown on our Energy-Efficient Windows page, including U-factor and SHGC ranges matched to San Francisco Climate Zone 3C.
Low-E & Argon Gas Glass
Signs you need it
Rooms on the south or west side overheat by mid-afternoon, or you feel radiant cold near windows on winter nights.
What it costs in Mission District
Expect $300 to $600 per opening for standard double-hung Low-E argon units in the Mission’s typical sizes.
How we do it
We measure each opening, specify the Low-E coating and gas fill for the elevation’s sun exposure, replace the units, and provide the manufacturer glazing specs in your final photo record.
UV-Blocking & Fade Protection
Signs you need it
Hardwood floors, rugs, or upholstery near bay windows are fading unevenly from the Mission’s stronger afternoon sun.
What it costs in Mission District
Plan on $340 to $740 per window for UV-blocking laminated or coated glass installed in an existing sound frame.
How we do it
We identify the failing glazing, specify UV-blocking glass with the right visible light transmission, install it, and leave you the coating documentation for warranty purposes.
What Energy-Efficient Windows Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Low-E argon double-hung window | $300 - $600 per opening |
| UV-blocking or fade-protection glazing | $340 - $740 per window |
| ENERGY STAR replacement (custom sash) | $520 - $1,100 per window |
Which energy rating matters most in the Mission District?
SHGC, the solar heat gain coefficient, matters most on south- and west-facing bays where the Mission’s sun load drives afternoon heat. A lower SHGC coating cuts that gain without making the room dark. We specify coatings per elevation, not per house.
Will energy-efficient windows change the look of my Victorian flat?
Only if the glazing is specified carelessly. We match the original sash profile and sightline, so the exterior appearance stays period-correct while the coating and gas fill do their work on the interior comfort side.
Sliding & Patio Doors in Mission District
Sliding and patio doors in Mission District homes often replace a rear service door off a deck, a garden egress, or a narrow utility opening that was never designed for modern glass. In many Victorian and Edwardian flats the rear openings are non-standard sizes, so the job is usually custom-fabricated rather than off-the-shelf. We cover the options in detail on our Sliding & Patio Doors page.
Patio Doors
Signs you need it
Rot at the bottom rail, failed rollers, or a door that no longer locks cleanly against settled framing.
What it costs in Mission District
Expect $1,200 to $2,700 for a standard-sized patio door replacement, with custom widths priced after the measured survey.
How we do it
We measure the rough opening, specify the door to fit the existing opening dimensions, remove the old frame, install and level the new unit, and seal against marine moisture.
Sliding Glass Door Replacement
Signs you need it
Condensation inside the glass, a track that has warped, or visible daylight at the stile interlocks.
What it costs in Mission District
Plan on $1,400 to $2,900 for a full sliding glass door replacement in the Mission District, including haul-away of the old unit.
How we do it
We pull the existing door, check the rough opening for square, adjust framing as needed, install the new sliding panel, tune the rollers, and document the seal lines.
What Sliding & Patio Doors Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Patio door replacement (standard) | $1,200 - $2,700 per door |
| Sliding glass door replacement | $1,400 - $2,900 per unit |
| Screen door installation | $190 - $430 per door |
Can you replace a sliding door without changing the Mission District rough opening?
Yes, in most cases we cut and install to the existing dimensions, which matters in Mission District flats where rear openings are often non-standard and enlarging them means structural work and DBI review.
How long does a patio door replacement take on a Victorian flat?
One day for the replacement itself, assuming the rough opening is sound. If we find rot at the bottom plate, which is common in Mission District rear walls, expect one extra day for framing repair at the written price we gave you before work started.
Impact Garage Doors in Mission District
Impact-rated garage doors in Mission District buildings are most common on newer construction or seismic-retrofit projects where the owner wants a wind-load-rated door that also stiffens the garage wall line. Older Victorian garages here are often narrow carriage-house openings, which means custom width fabrication rather than stock panel replacement. See our Impact Garage Doors page for product specifics.
Hurricane-Rated Garage Doors
Signs you need it
You’re replacing an old wood garage door, and the structure’s lateral load design calls for a wind-load-rated opening.
What it costs in Mission District
Expect $1,900 to $3,600 for an impact-rated single garage door installed, depending on custom width.
How we do it
We measure the opening, specify the door to the required wind-load rating, remove the old track and panels, install new track and door, and provide the rating documentation.
Garage Door Replacement
Signs you need it
Panels are rotted, springs are beyond service life, or the track has pulled loose from settling masonry.
What it costs in Mission District
Budget $1,400 to $2,900 for a standard garage door replacement in Mission District, excluding any framing repair.
How we do it
We remove the old door and track, replace any sagging header framing if needed, hang new track, install the door panels, and tension the assembly correctly, then document the full job.
What Impact Garage Doors Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Hurricane-rated garage door | $1,900 - $3,600 per door |
| Standard garage door replacement | $1,400 - $2,900 per door |
| Wind-load code compliance retrofit | $250 - $600 added per door |
Does San Francisco require impact garage doors?
Not by citywide mandate, but certain Mission District retrofit projects and newer multifamily buildings include wind-load ratings in their structural plans. We install to the spec the engineer has stamped, no more and no less.
Can you match the width of my old carriage-house garage door?
Yes. Many Mission District garages have non-standard widths from the original carriage era, and we order custom-width door sections rather than chopping a standard door, so the proportions stay right.
Custom & Geometric Windows in Mission District
Custom and geometric windows are not a luxury option in the Mission District; they are often the only option, because the original 1880-1920 sash profiles, arched transoms, and canted bay geometry don’t exist in modern stock catalogs. Matching the opening exactly is the job. Our Custom & Geometric Windows line is where we specify the unusual stuff.
Geometric & Shaped Windows
Signs you need it
Your building has a non-rectangular opening: a porthole, triangle, or pentagon from the original facade, and no stock window fits.
What it costs in Mission District
Plan on $900 to $2,200 per shaped window, including field measurement and fabrication drawing.
How we do it
We template the opening, draw the unit in CAD, get shop approval, fabricate or order it, install it with the right flashing, and photograph the final fit.
Arched & Curved Windows
Signs you need it
An arched transom or curved-top sash is failing, and a rectangular replacement would destroy the facade’s period grammar.
What it costs in Mission District
Expect $1,100 to $2,600 for an arched or curved window, depending on radius and whether the original jamb is reusable.
How we do it
We measure the true arc, match the radius in fabrication, install the curved unit into the original jamb if it’s sound, and seal the brick or wood surround against moisture.
What Custom & Geometric Windows Costs in Mission District
| Item | Typical range in Mission District |
|---|---|
| Geometric or shaped window | $900 - $2,200 per window |
| Arched or curved window | $1,100 - $2,600 per unit |
| Oversized opening custom glazing | $1,600 - $3,800 per opening |
Can you match the exact mullion profile on my Mission District windows?
Yes. We mill mullions and sash to match the original profile and sightline, then use matching glazing bars. The goal is that a neighbor can’t tell the window was replaced, only that it’s no longer failing.
How long does a custom geometric window take?
Fabrication typically runs three to six weeks after the template is signed, depending on shape complexity and finish. We’ll put that timeline in the written quote so there’s no surprise later.

FAQs About Windows & Doors in Mission District
Scheduling depends on the current permit queue, but once the DBI review clears we can usually start within two to three weeks. Emergency board-up or glazing calls, like a broken pane on a street-facing bay, get priority in the schedule. Call (509) 265-6387 and our live team will give you the straight answer.
Some buildings fall under San Francisco’s historic review programs or local design guidelines, especially those with intact Victorian facades. The relevant restriction is usually about matching original profiles and materials, which is work we do as a matter of course. We can help with the documentation the reviewing body asks for.
Yes. We prepare the drawings and handle DBI submittal for the window and door scope we’re installing, including the structural engineer’s involvement when a canted bay assembly is involved. The permitting work is in the written quote, not a bolt-on surprise later.
