AfterFast, Reliable Door Installation Across San Francisco
Door installation in San Francisco costs between $1,200 and $4,800 for most front entry replacements, with historic-district-matched custom units running higher. That’s a wide range, and most of it comes down to one thing: whether your house sits in the fog belt or not. Westlight Windows & Doors has installed doors across the city since 2009, from Outer Sunset Victorian flats to Pacific Heights Edwardians, and we know which spec holds up where. Call (903) 354-7134 for a written quote before any work starts.
Why Westlight Windows & Doors Is San Francisco’s Preferred Door Installation Company
San Francisco homeowners tend to have a story about a contractor who didn’t come back. Owen Satterfield started Westlight in 2009 to run a company that answers the phone, shows up in the window it gave, and puts every promise in writing. When our technicians walk your front door in the Mission, Noe Valley, or the Outer Richmond, they’re background-checked, uniformed, and they’ll leave your entry cleaner than they found it.
What actually sets us apart in San Francisco is that we’re not guessing at the fog line. We know a Marin-facing entry in the Outer Sunset needs a different threshold flashing detail than a protected Dolores Heights doorway. That local knowledge gets priced into your written quote up front, not discovered as a change order after the old jamb comes out. Every San Francisco job carries the Kingswell Guarantee: a written price before work starts, a committed arrival window, a clean site, and a written guarantee on the completed work. If something fails within the guarantee period, we come back and fix it at no charge. It’s the 365-Day Done Right Promise, and it’s handed to you in writing at job completion. Live phone coverage runs 24/7. A real person picks up, not a voicemail tree.
Front Door Replacement in San Francisco
Front door replacement in San Francisco is rarely a simple slab swap. The city’s housing stock is dominated by attached wood-frame Victorians and Edwardians built between the 1880s and 1915, and most of those entries have non-standard widths, paired door configurations, and transom lights that a stock unit from a big-box store will not match. In designated historic districts, San Francisco Planning Department design review requires the replacement door to closely match the original profile, panel layout, and stile width. That means off-the-shelf fiberglass or steel slabs are a non-starter in the Mission, Castro, Pacific Heights, and dozens of other protected pockets.
What a Real Front Door Job Involves Here
Most San Francisco front door replacements with us start with frame assessment. If the jamb ends and threshold are sound, we set a new pre-hung unit with stainless fasteners, a sill pan, and proper backer rod and sealant at the jambs. If the frame is soft, which is common on fog-facing entries, we pull the whole assembly and sister new jamb stock before setting the door. You get a written line-item quote before any of this begins, and the price does not change at the door.
Front Door Replacement Costs in San Francisco
A standard single front door replacement in San Francisco typically runs $1,200 to $3,800 installed. When historic-district design review requires a custom or clad-wood unit with a matching transom, that number moves to $4,000 to $8,000 or more depending on species, glazing, and hardware. We carry entry systems from Therma-Tru and impact-rated lines from PGT and CGI, so we can match both the aesthetic and the performance requirement without forcing the job to fit one brand.
Door Replacement in San Francisco
Door replacement in San Francisco often means more than the visible slab. The marine fog that sits against west-side entries in the Outer Sunset and Outer Richmond wicks moisture into the bottom rail and threshold, and the rot can run hollow beneath paint that still looks intact. A slab-only swap covers that soft frame, but the door keeps moving, sticks in July, and drafts all winter. Our crews plan for full-frame replacement on nearly every fog-belt Victorian job because experience has taught us the frame is usually gone before the door is.
When a San Francisco Homeowner Needs Replacement Doors
You need a door replacement when the leaf no longer seals against the jamb, when the bottom edge shows visible rot or water staining, or when the threshold has gone spongy underfoot. San Francisco’s salt-laden west-side air also pits zinc-plated hinges and strikes within a few seasons, leaving sagging doors and stripped screw holes. We spec stainless or hot-dip galvanized hardware and marine-grade finishes on any entry west of Twin Peaks, and on any door exposed to prevailing ocean wind.
Door Replacement Costs in San Francisco
Full door replacement with frame work in San Francisco typically runs $2,000 to $4,800 for a standard single entry. Paired doors, French units, and doors with operable transoms run higher, often $5,000 to $9,000 depending on species, glass packs, and hardware. Every quote is written, line-itemed, and fixed before we order materials. No revised invoices at the door, no surprise frame-rot upcharge after demo. That is the Kingswell Way.
Trusted Brands We Service in San Francisco
We install and service doors from eight manufacturer lines, but for San Francisco’s coastal conditions and historic profiles we lean heavily on three: Therma-Tru for genuinely weathertight fiberglass entry systems, PGT for impact-rated units on exposed elevations, and CGI for heavy-duty coastal hardware packages. Because we stock local parts and weatherstripping profiles for these lines in our San Francisco Bay Area shop, turnaround on warranty work and hardware replacements is days, not weeks. You’re never waiting on a part to ship from a distributor across the country while your front door won’t latch.
Common Door Installation Problems We See in San Francisco Homes
- Rotted thresholds and jamb ends on fog-facing entries. In the Outer Sunset and Outer Richmond, morning fog sits against the door leaf for hours, water wicks into the bottom rail and jamb ends, and the rot runs hollow beneath intact paint. A slab swap just covers a soft frame that keeps moving.
- Corroded zinc-plated hardware. Salt-laden Pacific air pits standard hinges, strikes, and threshold screws on west-side entries within a few seasons, leaving sagging doors and stripped screw holes. We spec stainless or hot-dip hardware on any entry west of Twin Peaks.
- Historic-district profile mismatches. In the Mission, Castro, and Pacific Heights, a stock door with the wrong stile width, panel layout, or transom proportion fails Planning design review. That delays the permit and forces a custom or clad-wood order after the fact, so we spec to match the original from the start.
- Bay-window-adjacent entries with mismatched sealing details. San Francisco’s three-sided oriel bays create complex flashing intersections at the jambs, and standard caulk joints fail within months under fog-driven moisture. We use backer rod, properly lapped sill pans, and marine-grade sealant at every transition.

FAQs About Door Installation in San Francisco
Because the fog belt destroys the threshold and jamb ends before the slab fails, and a stock door does not address the soft frame underneath. In the Outer Sunset, morning fog sits against the door leaf for hours, water wicks into the bottom rail, and the rot runs hollow beneath intact paint. You need a full-frame replacement with a sill pan, stainless fasteners, and proper flashing, not just a new slab hung on a soft jamb. Call (903) 354-7134 and we’ll tell you what your frame actually needs, for free.
Yes. Pacific Heights sits inside San Francisco’s designated historic districts, which means Planning Department design review requires replacement doors to closely match the original paired-entry profile, panel layout, and transom configuration. A stock slab that passes in Oakland or Berkeley will fail design review in Pacific Heights. You need a custom or clad-wood unit matched to your building’s original stile width and glazing pattern. We spec to match the original from day one so permits don’t stall.
The bottom rail and threshold fail first on fog-facing entries, and the hardware fails first on salt-exposed entries. In the west side of the city, water wicks into the door bottom and jamb ends every morning; in salt-laden air zones, zinc-plated hinges and strikes pit and strip within a few seasons. Both failure modes are predictable, which is why we write the coastal-spec into the quote up front instead of discovering it after demo. Call (903) 354-7134 for a free estimate that accounts for your actual exposure.
Salt air forces us off zinc-plated fasteners entirely. We spec stainless or hot-dip galvanized hinges, strikes, threshold screws, and weatherstripping on any San Francisco entry west of Twin Peaks, and marine-grade finishes on the visible hardware. Standard zinc hardware pits within a few seasons of Pacific salt exposure, leaving sagging doors and stripped screw holes. The hardware upgrade is a line item on your written quote, typically $80 to $250 depending on the door, and it buys you a decade of clean operation instead of three years of corrosion.
Usually not, unless your entry is directly exposed to wind-driven debris on an upper hill elevation or you want the added break-in resistance. San Francisco’s building code does not require impact-rated glazing on standard residential entries, but if your door has glass panels or a transom adjacent to a projecting bay window on a windward slope, we may recommend PGT or CGI impact-rated units for the added structural strength. It’s a judgment call based on your specific elevation and exposure, and we’ll give you a straight answer with the cost broken out in writing.
