AfterHow Much Does Windows & Doors Cost in San Francisco?
Window and door replacement in San Francisco typically runs between $750 and $1,850 per window opening and $1,200 to $4,500 per door, including basic installation. A full-home window replacement of 8 to 12 windows generally lands between $9,000 and $22,000, depending on the building’s age, how many stories the home has, and whether the exterior is wood, stucco, or a historic facade that requires special handling. These numbers reflect what we see across neighborhoods like Noe Valley, the Richmond, the Sunset, Bernal Heights, and Pacific Heights in 2026, not a national average that ignores San Francisco labor rates and permit realities.

Windows & Doors Cost Breakdown (2026)
Here is what you can expect to pay in the San Francisco market right now. These are real ranges we quote, not vague ballparks.
| Item | Low End | High End | Most Common Range |
|---|---|---|---|
| Vinyl single-hung window (standard size, ground floor) | $750 | $1,100 | $780 – $950 |
| Vinyl double-hung or casement window | $900 | $1,400 | $1,000 – $1,300 |
| Fiberglass window (PGT, CWS, or Mr-Glass) | $1,100 | $1,750 | $1,250 – $1,600 |
| Aluminum window with impact glass (CGI, ES Windows, ECO Window Systems) | $1,300 | $2,200 | $1,500 – $1,950 |
| Bay window or bow window (3 – 5 panels, full frame replacement) | $2,800 | $6,500 | $3,500 – $5,200 |
| Standard entry door (steel or fiberglass, prehung, no sidelites) | $1,200 | $2,800 | $1,600 – $2,400 |
| Wood entry door (Therma-Tru, custom stain) | $2,000 | $4,500 | $2,600 – $3,800 |
| Sliding patio door (vinyl or aluminum, 6 ft) | $1,400 | $3,200 | $1,800 – $2,700 |
| French door set (interior, prehung) | $800 | $2,200 | $1,100 – $1,700 |
| Full-frame window replacement (adds trim work and stucco or siding repair) | +$150 | +$400 per opening | +$200 – $300 per opening |
These figures include the window or door itself, standard hardware, basic installation labor, and haul-away of the old unit. What they do not include: structural repairs once the old frame is exposed (rot around sills is common in the Sunset and Richmond, where fog and salt air work on wood year-round), lead paint abatement if your home predates 1978, or a building permit, which San Francisco requires for most window and exterior door replacements when the opening size changes.

What Affects Windows & Doors Pricing in San Francisco
San Francisco is not like other markets. The pricing here reflects a specific set of conditions: old housing stock, dense neighborhoods, fog and salt air, strict codes, steep streets, and buildings that do not always cooperate with a standard installation. Here are the factors that move your quote up or down:
- Age and construction of the home. The bulk of San Francisco’s housing stock was built between 1900 and 1940. Many of those homes have non-standard window sizes, meaning more custom millwork and more labor per opening. A 1920s Edwardian in the Mission will almost always cost more per window than a 1990s condo in SoMa, simply because nothing in the old building is square.
- Number of stories and access. A ground-floor window replacement is straightforward. A third-floor bay window in Noe Valley that requires scaffolding, or a window that faces a steep uphill sidewalk in Glen Park, adds labor hours and equipment fees. High-tension work on upper floors is done by our own background-checked crew, never subcontracted out without your knowledge.
- Frame material. Vinyl is the most affordable and performs well in San Francisco’s climate. Fiberglass costs more but resists expansion and contraction better in the temperature swings between the fog line and the sunny eastern neighborhoods. Aluminum suits modern homes and high-wind zones near the ocean, and brands like ECO Window Systems, ES Windows, and CGI offer impact-rated options for homes that get direct exposure near Ocean Beach or Land’s End.
- Glass package. Single-pane replacement with standard double-pane glass is the baseline. Upgrading to low-E, argon-filled, or sound-dampening glass adds $80 to $250 per window. In the Richmond and Sunset, where fog is a daily visitor, low-E glass helps keep interiors brighter and warmer without making the home feel sealed off. Sound-dampening glass is worth considering for homes facing busy corridors like Geary, 19th Avenue, or Van Ness.
- Historic preservation requirements. If your home sits within one of San Francisco’s designated historic districts, or if the building itself is landmarked, you may be required to match original window profiles, muntin patterns, and wood species. The planning department reviews these window changes and the approval process can add weeks and $1,000 to $3,000 to the job, depending on the scope. We handle the paperwork and coordinate with the city so the project moves forward without you needing to decipher planning code on your own.
- Permit fees. San Francisco’s Department of Building Inspection charges for most window and exterior door permits. Fees are modest compared to the cost of the windows themselves, but they are real, and our written quote includes them. You will not find a hidden permit line item at the end of the job.
One more thing worth naming: the condition of what is behind the old window. In homes near the water, like the Marina or the Bayview, we regularly find dry rot in the framing around windows once the old unit comes out. Rot repair adds $200 to $600 per affected opening. You will know about it before we start the repair, with a photo and a number. Nothing gets touched without your approval.
What Do Different Window Brands Cost in San Francisco?
We carry eight manufacturer brands, and we match the brand to the home rather than pushing whatever is sitting in a warehouse. Here is how the brand lineup shakes out on price and use case for San Francisco buyers:
- ECO Window Systems and Mr-Glass: The most value-driven options in our lineup. Vinyl and aluminum frames, clean modern profiles, good for rentals, flats, and budget-conscious remodels. Installed pricing from about $750 to $1,250 per window.
- PGT and CWS: Mid-to-upper range fiberglass and vinyl. Good glass packages, strong warranties, and a step up in fit and finish. Expect $1,100 to $1,750 per opening installed.
- ES Windows and CGI: Aluminum and impact-rated lines. These are common choices for homes in direct coastal exposure, buildings with high wind requirements, and contemporary renovations where thinner frames and larger glass panels matter. Installed pricing from $1,300 to $2,200 per window.
- Therma-Tru: Our primary entry door line. Fiberglass entry doors start around $1,600 installed; wood doors in premium stains run up to $4,500 depending on glass lites and hardware. Therma-Tru’s flush-glazed models read as modern, while their classic lines suit the Victorians and Edwardians throughout the city.
- ViewLux: Specialty glass, custom shapes, and larger-format openings. When a client in Pacific Heights wants floor-to-ceiling glass in a living room or a custom arch top to match a 1910 original, ViewLux is often the brand we order. Pricing is project-specific, but most custom ViewLux openings land between $2,000 and $4,000 installed.
The right brand for your home depends on the building’s age, the neighborhood, how much glass area you want, and how long you plan to stay. We walk through that decision with you before any numbers are finalized, because the brand choice has a real effect on the total price and on how the home feels from the inside.
A light well is what brings daylight deep into a building. That is what a well-installed window should do for your home. The brand matters less than how it is fitted, flashed, and sealed.
Door Replacement Costs in San Francisco
Doors are their own category. Entry doors in San Francisco deal with fog, rain, occasional heat, and the usual settling of older buildings. A door that swells in winter and sticks by March is not just an irritation, it is a signal that the frame has shifted or the seal has failed. Replacing the slab alone rarely fixes the problem in older homes, which is why we replace the prehung frame in most cases and treat the threshold and weatherstripping as part of the job, not an afterthought.
Standard fiberglass entry door with basic hardware: $1,600 to $2,400. That includes the prehung frame, new threshold, weatherstripping, interior and exterior trim where needed, and haul-away. Wood entry doors from Therma-Tru with a stain package run $2,600 to $3,800. Adding sidelites pushes the job to $3,500 to $5,500 depending on configuration. A sliding patio door, which is a popular swap in Inner Sunset and West Portal homes that open to a back deck, runs $1,800 to $2,700 for a standard 6-foot opening.
Security matters in San Francisco. Multi-point locking systems add $200 to $400 per door but are worth it for ground-floor entries and rear doors that face alleys or shared walkways. We install multi-point locks on Therma-Tru and fiberglass doors regularly, and it is a small add-on relative to the peace of mind it provides.
How to Save on Windows & Doors
Replacing windows and doors is a significant expense, but there are legitimate ways to keep the total down without cutting corners that will cost you later.
Replace in phases, not all at once. You do not need to do every window in the same month. We see many San Francisco homeowners phase the work: street-facing windows first, bedrooms second, rear windows later. Phasing spreads the cost across a year or two and lets you evaluate how the first phase performs in your home before committing to the rest. The downside is that labor setup costs repeat, so a mid-size phase (5 to 7 windows) is more cost-effective per window than doing one or two at a time.
Choose reasonably, not cheaply. The lowest-priced vinyl window installed badly will cost more than a mid-range window installed correctly. In a city as damp as San Francisco, the installation detail matters more than the brand logo. Flashing, sloping the sill pan, sealing the interior air barrier, and insulating around the frame are the details that prevent fog-caused moisture intrusion. Do not bargain away the labor quality.
Address rot early. When rot is caught early, it is a localized repair of $200 to $400. When it spreads behind the siding, it is a $2,000 to $5,000 rebuild of the wall section. If you notice paint bubbling near a window frame or soft wood around a door threshold, call for an inspection sooner rather than later.
Ask about spec sizes. If your opening happens to be close to a standard manufacturer size, you may be able to order an in-stock unit instead of a custom order, saving $150 to $500 per window depending on brand. Some older San Francisco homes have true standard sizes; many do not. We will tell you honestly which openings qualify.
Get a written estimate and compare it properly. Free estimates are standard for good window and door companies in San Francisco. Compare line items, not just bottom lines. One quote may look $800 cheaper but be missing a permit fee, sill pan flashing, or interior trim. We provide a written price before any work starts, every time. If you would like a detailed estimate for your home, call us at (831) 480-4124. Keith Yamada and our team can walk the property, take measurements, and put numbers on paper while you watch.
San Francisco Window & Door Projects We See by Neighborhood
San Francisco is a patchwork of microclimates and building styles. Here is what we encounter in specific parts of the city, and how it shapes cost:
Sunset and Richmond Districts: The fog belt. Homeowners here battle moisture, salt air, and a steady chill. Wood windows rot faster, vinyl and fiberglass hold up better, and low-E glass makes a noticeable difference in indoor comfort. Many of these homes are 1930s to 1960s stucco boxes with standard-ish window sizes, which keeps labor moderate. However, exterior stucco repairs around new windows are common and add $150 to $300 per opening.
Noe Valley, Bernal Heights, Glen Park: Hillside Victorians and Edwardians with bays, curved glass, and non-standard sizes. Expect more custom millwork, more time per opening, and in many cases, scaffolding for upper-floor work. These jobs run at the higher end of our per-window ranges, and the historic permitting path may apply.
Marina, Cow Hollow, Pacific Heights: Larger homes, more glass area, and higher-end finish expectations. Many of these projects include custom glass packages, sound-dampening layers for busy streets, and premium hardware. Budgets here often land between $20,000 and $40,000 for a full-home package, depending on the number of openings and the door selection.
Mission, Potrero Hill, Bayview: A wide mix of old and new construction. Condos and newer builds are easier installations with standard sizes. Older single-family homes can have everything from rotted sills to out-of-square openings. Bayview’s proximity to the bay means moisture and wind get considered in the glass and frame selection.
Inner Sunset, West Portal, Parkside: Family-heavy neighborhoods where homes often have original steel casement windows from the 1940s and 1950s. Steel casements are charming but inefficient and difficult to repair. Full-frame replacement to a modern casement or picture window is common here, and we work with brands like ES Windows and PGT that make replacement casements with cleaner sightlines.
Inside a Lightwell Window or Door Installation
If you have been burned before by a crew that left dust on the floors or handed you a surprise bill at the end, it helps to know exactly what our process looks like from the first call to the final walkthrough.
When you call, a live person answers. Not a recording. If it is 2 a.m. and something is wrong with a newly installed door, you will still reach a person. Keith Yamada leads our San Francisco team, and the promise is simple: the job is not done until it is done right, and you are not stuck navigating a phone tree to tell someone about it.
Before the crew arrives, you will know who is coming. Our technicians are background-checked and uniformed, so the person at your door is recognizable and accountable. They follow what we call the C.A.R.E. values on every visit:
- C – Clean up like it is our own home. Shoe covers and drop cloths go down before anything else. Equipment and old window debris never touch your bare floors. We take a photo of the clean-up before the crew leaves, every single visit.
- A – Ask before we move or touch anything. If a bookshelf needs to shift six inches to access a window, we ask first. If we need to move a planter on the deck, we ask. Nothing in your home gets handled without your say-so.
- R – Respect the family’s time and quiet hours. If a child or a baby is napping, we work around that. If you work from home, we keep disruption contained to the room we are in. This matters in San Francisco homes, where rooms are often close together and noise travels.
- E – Explain the price before the work. The number you approved is the number you pay. If we find something unexpected once the old window is out, we stop, show you a photo, explain the cost, and get your approval before proceeding.
The Cedarwell Care Promise and our 365-Day Done Right Promise cover every job. If the finished work is not right, we make it right. No debate, no countdown, no fine print. That applies to the windows, the doors, the flashing, the trim, and the clean-up. If something shifts or a seal fails within the first year, you call us and we return.
Frequently Asked Questions
How much does it cost to replace one window in San Francisco?
A single window replacement in San Francisco costs between $750 and $1,850 installed, with most falling between $900 and $1,400. If the window is on an upper floor, requires stucco repair, or falls under historic preservation rules, expect the higher end of that range. Call (831) 480-4124 for a free, written estimate on your specific windows.
Is it cheaper to repair windows or replace them?
Repairs typically cost $150 to $500 per window for work like replacing a sash cord, rebuilding a rotted sill section, or sealing a drafty frame. If the glass unit itself has failed, if the frame has rot in multiple places, or if condensation sits between the panes, replacement is usually the better long-term investment. In San Francisco, fog-driven moisture means a window with a failed seal will keep costing you, and replacement starts around $750 per opening. We will give you an honest read on repair vs. replace before quoting anything.
How long does a window replacement take in San Francisco?
A standard single-window installation takes 2 to 4 hours. A full-home package of 8 to 12 windows takes 1 to 3 days on site, depending on access, framing repairs, and weather. Permit wait times in San Francisco can add 2 to 6 weeks to the overall timeline for projects where permits are required, so we recommend starting the permit paperwork early. We handle the city process for you.
Do I need a permit to replace windows or doors in San Francisco?
Yes, San Francisco’s Department of Building Inspection typically requires a permit when a window or exterior door opening changes size or the project involves structural work such as new framing. Like-for-like replacements of the same size sometimes qualify for an over-the-counter permit. Our written quotes include permit fees when they apply, and we manage the filing. You will not be surprised by a permit cost at the end.
What is the most cost-effective window brand for San Francisco weather?
For most San Francisco homes, a well-installed vinyl window from ECO Window Systems or Mr-Glass is the most cost-effective choice, running $750 to $1,300 per opening. If your home gets direct ocean exposure or sits on a windy ridge, stepping up to a fiberglass or aluminum impact-rated line from PGT, CWS, ES Windows, or CGI is worth the extra $300 to $700 per window. The biggest factor is not the brand name on the frame; it is how the window is flashed and sealed against San Francisco’s fog and rain.
Can you replace windows or doors the same day?
In most cases, yes for a small number of windows or a single door. We keep common stock sizes from our brand lineup available, and our crews can usually complete a 1 to 3 window job in a single visit. Custom sizes and historic replacements require ordering lead time, which runs 4 to 10 weeks depending on the manufacturer. If you need something done urgently, call (831) 480-4124 and we will tell you exactly what can happen today and what cannot.
How much does a full house of windows cost in San Francisco?
A full-home window replacement of 8 to 12 windows in San Francisco costs between $9,000 and $22,000 installed. Historic homes with custom sizes and upper-floor access, such as Victorians in Noe Valley or the Mission, trend toward $18,000 to $22,000. Mid-century homes in the Sunset or Ingleside with standard sizes often land between $9,000 and $14,000. Your written quote will itemize every opening so you can see where the money goes.
