AfterFast, Reliable Window Replacement Across San Francisco
Window replacement in San Francisco typically runs $900 – $1,800 per window installed, and most jobs take four to eight weeks from first measurement to final inspection. That range covers standard double-hung replacement units in wood-framed homes. Larger picture windows, bay window rebuilds, and anything in an Article 10 or Article 11 historic district will land higher, sometimes $2,500 – $4,000 per opening. If you’re in the Marina, Noe Valley, the Richmond, or out toward the Sunset, you’re dealing with housing stock that’s 80 to 120 years old, and the window openings are rarely square anymore. That’s not a problem if the crew knows to field-measure every rough opening before ordering. It’s a schedule killer if they don’t. Call (817) 686-2228 and we’ll walk you through what your building actually needs, free.
Our Window Replacement team works across San Francisco every week, from single-family Edwardians to top-floor condos on hillside lots. We’re familiar with DBI’s permit process, the historic preservation overlays, and the wind exposure conditions that make a catalog window the wrong window in parts of this city.
Why Meridian Windows & Doors Is San Francisco’s Preferred Window Replacement Company
Elliot Vance runs our San Francisco operation. He’s the one who reviews every quote before it reaches you, and he’s the one who takes the call if something goes sideways after the install. That’s not a sales pitch; it’s how we’re structured. Meridian is a windows-and-doors specialist within the Garrison Partners family, operating to The Garrison Standard since 2009. Every job gets a written price before work starts, and every install is covered by our 365-Day Done Right Promise. If it fails within the year, we return at no charge. No labor exclusions, no fine print.
San Francisco homeowners tell us the same three things over and over: they’ve had a contractor no-show, they’ve had a quote change at the door, or they’ve had a crew leave the sill flashing unfinished. We run on discipline because the city’s building stock demands it. A 1920s house in the Sunset doesn’t forgive sloppy flashing. A bay window on a Russian Hill slope doesn’t forgive a skipped design pressure calculation. We answer the phone with a live person 24 hours a day, seven days a week, because when a window fails during a January storm, you shouldn’t get a voicemail loop.
Every technician who walks through your door is background-checked and uniformed. You’ll know exactly who’s in your home. The price goes on paper before any work starts, and it does not move at the door. That’s the whole point of a meridian: it’s a fixed line you measure everything against. That’s what the name means and how we run every install.
Energy Efficient Windows in San Francisco
Energy Efficient Windows in San Francisco are a different conversation than they are in Walnut Creek or Concord. The marine layer and fog push moisture against west-facing walls for months at a time. The gain in this city is less about cooling load and more about stopping air infiltration through 100-year-old sashes and keeping condensation from soaking into the frames. Low-E glass (a thin coating that reflects heat while letting light through) does real work here, but the bigger win is a properly installed replacement unit with new weatherstripping and a sealed rough opening.
Most energy-efficient upgrades in San Francisco run $950 – $1,600 per window installed when the existing frame is sound. If the frame has rot (common in the Richmond and Sunset where fog exposure is constant), a full frame replacement pushes the cost to $1,500 – $2,800 per opening.
Low-E Glass and Bay Area Moisture
We spec low-E insulated glass units on almost every San Francisco job. The thin metallic coating reflects radiant heat back into the room during winter and blocks a meaningful slice of solar gain in summer. But the moisture argument is the one that matters here. Single-pane wood sashes in a 1920s Outer Sunset house will condense and drip every foggy morning. That moisture sits in the sill channel, the wood swells, the paint fails, and rot follows within a few seasons.
When to Choose a Full Frame Replacement
If the existing frame is square, dry, and structurally sound, an insert window saves labor and preserves the interior casing. If the frame has soft spots at the sill corners or the rough opening has shifted out of square due to settling, the insert won’t seal properly and you’ll be fighting drafts forever. In San Francisco’s pre-war housing stock, we see settled openings all the time. We field-measure every rough opening before ordering. That’s the only way to avoid a unit arriving that doesn’t fit.
Window Repair in San Francisco
Window Repair in San Francisco is often the right call instead of full replacement, especially in historic districts where full-new sashes trigger the Article 10 or Article 11 process. Repairing the existing sash, replacing broken sash cords, re-puttying glazing, and installing new weatherstripping frequently restores a window to functional and energy-decent condition at a fraction of the cost. Our repair work in San Francisco typically runs $180 – $400 per window for common sash repairs, cord replacement, or glazing, and $350 – $700 when we need to rebuild a sill or jamb liner.
San Francisco homeowners often don’t realize how repairable their original wood windows are. These old-growth redwood and Douglas fir frames have lasted 100 years. The problems are predictable: broken double-hung cords, failed glazing putty, sashes painted shut, or weatherstripping that’s turned to dust. None of that requires a full replacement.
When a Repair Isn’t Enough
Repair makes sense when the sash and frame are structurally sound and the glass is intact. If the glass is single-pane and you’re tired of condensation, or if the frame has rot through the sill, repair becomes patchwork. We’ll tell you straight when a repair is a waste of your money.
Repairs and Historic Districts
For homes in San Francisco’s Article 10 and Article 11 historic districts, repair is the low-friction path. The Planning Department doesn’t trigger Historic Resource Review for in-kind repair work that doesn’t change the visible profile. Replacement that preserves the exact mullion pattern can be done, but it takes a longer permit path. We’ll map that for you before you spend a dollar.
Trusted Brands We Service in San Francisco
We install and service windows from eight manufacturer lines, and we stock common replacement parts for San Francisco customers so repairs don’t wait on a truck from the East Bay. For most San Francisco homes, we lean on ViewLux for their slim-line aluminum and thermally broken frames that suit mid-century and contemporary builds in areas like Diamond Heights and the newer construction near Mission Bay. In wind-exposed hillside locations, PGT and CGI impact-rated windows are the move when design pressure calculations push beyond what a stock catalog unit is rated for. Every brand gets the same written 365-Day Done Right Promise on installation.
Common Window Replacement Problems We See in San Francisco Homes
- Out-of-square rough openings in pre-war buildings. Settling over 80 to 120 years means the opening is no longer a rectangle. If the replacement unit is ordered before field measurements, it doesn’t fit, and the schedule slips by weeks.
- Historic district complications on street-facing elevations. A same-size replacement in an Article 10 or Article 11 district can still trigger Historic Resource Review if the sash profile or mullion pattern changes. We’ve seen permit sets get kicked back for exactly this and add three to six weeks.
- Fog-driven rot at sill corners. The Richmond, Sunset, and Parkside get hammered by marine layer moisture. West-facing windows with failed caulk lines rot quietly at the sill. By the time you see paint peeling, the damage is usually already in the wood.
- Inadequate design pressure ratings on hillside exposures. San Francisco’s wind tunnel effects between buildings and exposed upper-floor openings can require a stronger unit than the catalog says. We run site-specific calculations on every upper-floor or exposed-corner install.
Pricing for Window Replacement in San Francisco, CA
Honest numbers, because the internet is full of vague ones. A standard insert window replacement in San Francisco runs $900 – $1,600 per unit installed. Full frame replacement, which involves tearing out the old frame and flashing the opening properly, runs $1,500 – $2,800 per unit. Bay window rebuilds land between $3,000 and $6,500 depending on size and structural condition. Jobs in Article 10 and Article 11 historic districts add $500 – $1,500 in permitting and review costs. The price on paper before we start is the price you pay. If a hidden condition alters the scope, we stop and re-quote in writing before touching it. Call (817) 686-2228 and we’ll walk through your specific building, your specific measurements, and give you a line-item price. The estimate is free.

FAQs About Window Replacement in San Francisco
Yes, in most cases. San Francisco’s Department of Building Inspection requires a permit for window replacement when the work is not a simple in-kind repair. A same-size replacement in a non-historic district is typically a straightforward alteration permit. But if the building sits in an Article 10 or Article 11 Historic Resource district and the visible sash profile or mullion pattern changes on a street-facing elevation, the permit goes through Historic Resource Review before approval. We handle the permit filing and coordinate inspections. Call (817) 686-2228 and we’ll tell you which path applies to your address.
Plan on four to eight weeks for a typical San Francisco window replacement. Field measurements take one visit. Ordering custom-sized units runs two to four weeks depending on the manufacturer. Installation for a standard single-family home runs one to three days. DBI inspection typically gets scheduled within a week of completion, and if the work is done correctly, there’s no correction notice. Historic Resource Review, if triggered, adds three to six weeks on the front end. We’ll give you a calendar in writing before you commit.
Four things. First, whether it’s an insert into a sound frame or a full frame replacement. Second, the window’s location: upper floors, bay windows, and exposed hillside corners cost more because of access and design pressure requirements. Third, whether the building is in a historic district, which adds review fees and sometimes requires custom millwork. Fourth, the glass spec: low-E insulated glass is standard for us, but laminated glass for noise reduction on busy corridors adds $150 – $300 per window. Every quote includes these line items in writing.
Yes. We repair more windows than we replace in San Francisco. Sash cord replacement, glazing, weatherstripping, and sill rebuilding are all common jobs for us, especially in Noe Valley and the Richmond where original wood windows are worth preserving. Repairs run $180 – $700 depending on scope. If a repair won’t solve the underlying problem, we’ll say so and give you the replacement cost. You decide with real information.
Hidden rot is the big one. If we remove a window and find the rough opening compromised by long-term moisture, the frame repair is additional scope. We stop, document what we found, and give you a written change order before touching it. Nothing gets added to your bill without your signed approval. That’s the Garrison Standard, and it’s been how we operate since 2009. Call (817) 686-2228 for a free estimate on your San Francisco window project.
