Window Company in San Francisco, CA
Most window and door jobs in San Francisco run $800 – $3,200 per opening depending on the product and the condition of the existing frame, with full-home window replacements typically landing between $15,000 and $35,000. The city’s Victorian and Edwardian housing stock, combined with Planning Department historic-review requirements in many districts, means San Francisco window work demands different products and skills than standard suburban vinyl swaps. At Lightwell Windows & Doors, we carry PGT, CGI, CWS, and ViewLux lines suited to these constraints, and every job starts with a written price before any work begins.

Why San Francisco Homes Are Different
San Francisco’s dominant housing stock of Victorian (1880s – 1900s) and Edwardian (1900s – 1920s) wood-frame row houses, concentrated in the Western Addition, Castro, Haight-Ashbury, and Mission, means most window jobs involve original wood sash units with rope-and-pulley or chain counterbalance systems. Many of these fall under the city’s historic district controls, which require Planning Department review before replacement and mandate historically-compatible profiles. That preservation-first regulatory layer effectively rules out the standard vinyl-swap approach common in neighboring cities.
The Outer Sunset and Outer Richmond add another variable: tens of thousands of post-WWII stucco homes with original steel casement or jalousie windows that corrode heavily in the salt-laden marine air. In fog-belt neighborhoods west of Twin Peaks, west-facing wood window sills can be structurally rotted all the way through while interior paint still looks intact. Moisture drives inward from outside, so by the time a homeowner feels a draft, the rough framing and sill plate are usually part of the repair scope too. Unlike the rest of California, heat expansion is almost never the failure mode here; persistent humidity cycling is almost always the culprit.
Our Main San Francisco Services
San Francisco homeowners call us most often for window replacement and new window installation, though door installation is growing quickly as families update entry systems for security and energy performance. Each service page below details how we handle San Francisco’s specific conditions.
Window Replacement in San Francisco
Window replacement in San Francisco typically means removing original wood sash units from Victorian and Edwardian homes and installing new products that satisfy both the homeowner and the Planning Department’s historic compatibility requirements. We regularly see jobs in the Castro and Haight-Ashbury where the counterweight pocket has been damaged by decades of fog-driven moisture, requiring carpentry repair before the new unit goes in. Our crews carry shoe covers and drop cloths on every visit, and we photo-document the clean-up before leaving. Window Replacement in San Francisco

Window Installation in San Francisco
New window installation in San Francisco often happens in converted attics, rear additions, or garage conversions where the original structure never had an opening. In the Sunset and Richmond districts, we frequently cut into stucco exteriors that have been saturated by marine fog for sixty-plus years, requiring careful flashing detail to prevent the moisture problems that plagued the original steel casements. We pull permits and coordinate inspections as part of every job. Window Installation in San Francisco

Door Installation in San Francisco
Door installation in San Francisco presents unique challenges because wood doors swell and rack in their jambs seasonally due to humidity cycling, and many Victorian entryways have non-standard rough openings that require custom jamb work. We install Therma-Tru and ViewLux entry systems with proper sill pan flashing to handle the moisture load, and we always explain the price before touching anything.
