How Much Does Windows & Doors Cost in San Francisco?

Most single-window replacements in San Francisco run $850 to $2,400 installed, and most entry-door replacements run $1,900 to $6,500 installed, depending on product line, frame material, and how much trim and stucco work the opening needs.

A full-house window package on a typical two-bedroom Sunset or Richmond District home usually lands between $9,500 and $28,000 before any permit fees, while a single exterior door swap on a Noe Valley Victorian typically comes in around $2,200 to $5,000. Those ranges reflect what we actually quote in San Francisco, not a national average pulled from a lead-generation site.

Westlight Windows & Doors has been installing windows and doors since 2009 as an independently owned and operated Kingswell location, and every San Francisco homeowner we work with gets a written price before a single screw turns.

Windows & Doors Cost Breakdown (2026)

Here’s how the numbers shake out across the product categories we install. All figures are installed cost, meaning the product, labor, disposal of the old unit, and standard flashing and sealing are included.

What pushes a job toward the top of those ranges? Custom sizing on an old Victorian opening, lead paint remediation on pre-1978 homes, second-story or third-story access that requires scaffolding, and premium product lines like impact-rated PGT or CGI aluminum. What keeps it at the bottom? Standard sizes that match factory dimensions, first-floor access, and choosing a stocked ECO Window Systems or CWS vinyl line over a custom finish.

The single biggest cost driver we see in San Francisco isn’t the window itself. It’s the opening. A 1910 Inner Sunset building with a plaster return and original redwood trim takes more labor to detail correctly than a 1998 Mission Bay condo with a clean vinyl frame and drywall return.

What Affects Windows & Doors Pricing in San Francisco

• Building age and construction type. San Francisco has a huge stock of pre-1930 wood-frame homes with plaster walls and true divided-light windows. Those openings usually need custom sizing and careful trim work, which adds $200 to $600 per opening compared to a modern replacement.
• Permit requirements. The San Francisco Department of Building Inspection requires a permit for window replacement that changes the opening size or alters the exterior envelope. Like-for-like replacements in kind are often exempt, but we confirm before work starts so nothing lands on you unexpectedly. Permit fees typically run $300 to $1,200.
• Lead paint (pre-1978 homes). Most of the Sunset, Richmond, Bernal Heights, and Noe Valley housing stock was built before 1978. Federal EPA Renovation, Repair and Painting rules apply, which means containment, cleanup verification, and certified crews. That adds roughly $150 to $400 per opening on affected jobs.
• Fog, salt air, and marine exposure. Homes in the Outer Sunset, Ocean Beach, and the Marina take constant salt-laden moisture. We specify corrosion-resistant hardware and heavier frame finishes there as standard, because a cheap hinge or a thin finish will fail in three or four years on those blocks.
• Access and staging. Third-floor walk-ups, narrow side yards in the Mission, and steep lots in Twin Peaks all add labor. Scaffolding alone can add $1,500 to $4,000 to a full-house job.
• Product line. We carry eight manufacturer lines, including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. The right choice depends on your exposure, your budget, and whether you want impact-rated glass, energy-efficient low-e glass (a thin coating that reflects heat back into the room in winter and out in summer), or a specific look.

How to Save on Windows & Doors

You can absolutely bring a San Francisco window or door project down without cutting corners, and we’d rather you ask than guess.

• Bundle openings. A full-house package almost always costs less per window than a one-off replacement, because mobilization, staging, and permit work are amortized across the job. The savings typically run 10 to 20 percent per opening.
• Choose a stocked product line when it fits. ECO Window Systems and CWS vinyl lines cover most standard and near-standard openings at a lower price than fully custom aluminum. If your home’s look allows it, that’s an easy $150 to $400 per window.
• Replace, don’t reconfigure. Keeping the existing opening size and location avoids structural work, reframing, and higher permit classification. It’s the single biggest line-item lever on a San Francisco job.
• Do it before the fog season, not during. Scheduling in late spring or early fall can mean faster lead times and less weather-related delay.
• Ask for a written price up front. This is the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails. Every Westlight quote arrives in writing, and we don’t revise it at the door.

FAQs - Windows & Doors Cost

How much does it cost to replace a single window in San Francisco?

A single window replacement in San Francisco typically runs $850 to $2,400 installed, depending on frame material, glass type, and how much trim and finish work the opening needs. A standard first-floor vinyl double-hung in a Bayview home usually lands near the bottom of that range; a custom-sized aluminum impact-rated window on a third-floor Marina unit lands near the top. Call (903) 354-7134 for an exact number – estimates are free.

Is it cheaper to repair or replace a window in San Francisco?

Repair is cheaper when the frame and sash are still sound – usually $150 to $500 for a new balance, sash, or glazing bead. Replace when the frame is rotted, the seal has failed and fogged the glass, or the unit is a single-pane original that’s leaking heat. In San Francisco’s pre-1930 housing stock, we see a lot of frames that look repairable until the trim comes off and the bottom plate is soft. If two or more of those conditions apply, replacement wins on cost over five years.

How much does a new exterior door cost in San Francisco?

A new exterior entry door in San Francisco runs $1,900 to $4,200 installed for steel or fiberglass, and $3,400 to $6,500 installed for wood with a custom finish. Therma-Tru is our most-requested entry-door line because the fiberglass and steel models hold up well against salt air. Hardware upgrades, sidelights, and transoms add to the total. Call (903) 354-7134 and we’ll price your exact door and opening.

Do I need a permit to replace windows in San Francisco?

Sometimes. The San Francisco Department of Building Inspection generally requires a permit when window replacement changes the opening size, alters the exterior envelope, or involves more than a like-for-like swap. Straight replacement-in-kind often qualifies as exempt, but it’s determined case by case. Permit fees typically run $300 to $1,200. We confirm the classification before any work is scheduled, so there are no surprises on the invoice.

How long does a window or door installation take in San Francisco?

A single window or door takes half a day to a full day. A full-house window package on a San Francisco home typically runs three to six days, and a full-house package plus doors runs five to ten days. Scheduling matters here: weather, building access, and HOA or landlord approvals can each add time. When we quote, we give you a real arrival window and keep it. That’s not a marketing line – it’s one of the five Kingswell promises we put in writing on every job.

Can you come today if I have a broken window or a door that won’t secure?

In most cases, yes for secure-up and temporary measures, and we’ll schedule the permanent repair as soon as the product and crew are available. Our phone lines are staffed by a live person 24 hours a day, seven days a week – not a voicemail box, not a chatbot. Call (903) 354-7134 and a real human will pick up, answer your questions, and either schedule the work or dispatch help.

Why Homeowners Call Westlight in San Francisco

Westlight Windows & Doors has been doing this work since 2009, as an independently owned and operated Kingswell location. Owen Satterfield leads the company and every job is governed by the Kingswell Guarantee: a written price before any work starts, a committed arrival window, a clean job site, and a written guarantee handed to you at completion. If a repair fails within the 365-Day Done Right Promise period, we come back and fix it at no charge. No negotiating, no fine print.

Our technicians are background-checked and uniformed, so you know exactly who is walking through your door. We carry eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – which means we match the right product to your opening and your exposure, rather than forcing your job into whatever a single manufacturer happens to sell. And when we leave, the site is cleaner than we found it. That’s a promise, not a slogan.

If you’ve been burned before by a contractor who no-showed, revised the price at the door, or vanished when a seal failed six months later, we understand. We built our process around exactly those failures.
