Why Supplier + Installer Matters
Why Supplier + Installer Matters
Most homeowners don't realize that big-box stores and national window brands use subcontracted installers — meaning the company that sold you the window isn't the company putting it in. If something goes wrong, you're caught between two warranties and two phone numbers.
The contractor we connect you with is different. They supply and install every window themselves — direct dealer pricing on Milgard, Anlin, Marvin, and Simonton, installed by their own licensed crew. One company. One warranty. One call if anything ever needs attention.
This is also why our pricing calculator reflects real numbers. The contractor sets their own supply and installation pricing — no showroom markup, no franchise fee, no separate labor quote from a subcontractor.
Window Brands Your Contractor Installs
The Brands Bay Area Homeowners Trust
The contractor we connect you with is a direct dealer for the four brands most requested by Bay Area homeowners. They stock, supply, and install all four — dealer pricing and expert installation from the same company. Here's what you need to know about each brand.
Milgard
Milgard is the most widely installed window brand in California. Known for their lifetime warranty, energy efficiency, and wide product range — from the affordable Tuscany Series to the premium Trinsic.
Anlin
Anlin windows are manufactured in California specifically for the California climate. Their Del Mar and Catalina series offer exceptional energy performance and a True Lifetime Warranty that transfers to new owners.
Marvin
Marvin is the choice for homeowners who want premium wood-clad or fiberglass windows with exceptional aesthetics. Ideal for craftsman, Victorian, and high-end contemporary Bay Area homes.
Simonton
Simonton offers excellent value for budget-conscious Bay Area homeowners. Their StormBreaker Plus and Reflections series deliver solid energy performance and durability at a more accessible price point.
We connect you with a local, independent window contractor — one company that supplies and installs, start to finish. Not a national chain. Not a call center. Not a lead farm that sells your information to twelve contractors. You hear from one company. That's the entire model.

Compliance
Window Replacement Permits in San Francisco
Window replacement in San Francisco requires a building permit issued by the San Francisco Department of Building Inspection (DBI). As of February 13, 2026, in-kind window replacements — same size, same opening, no structural changes — are processed entirely online through the DBI portal. No visit to the Permit Center is required for standard retrofits.
Permit fees in San Francisco are calculated as a percentage of project valuation, typically ranging from 6–9% of the total construction cost. Homes in San Francisco's many Historic Districts — including Alamo Square, Haight-Ashbury, Liberty Hill, and others — may require Planning Department review before a permit can be issued, which adds time to the process.
The contractor we connect you with handles all permit applications and coordinates required inspections. You don't need to navigate the DBI process yourself.

Performance
San Francisco Climate and Window Performance
San Francisco's climate is dominated by fog, marine layer, and year-round cool temperatures — the opposite of inland Bay Area cities. Most SF homeowners spend far more on heating than cooling, making heat retention the primary window performance goal. The key specification here is U-factor: how well a window keeps heat inside.
Title 24 requires a U-factor of 0.30 or lower for replacement windows in San Francisco's climate zone. In practice, most Bay Area contractors recommend U-factors of 0.25 or below for SF homes, especially in neighborhoods west of Divisadero where the marine layer is most persistent. Low-U factor windows with warm-edge spacers and quality weatherstripping prevent drafts and moisture buildup in older Victorians and Edwardians with balloon framing.
For homes near the ocean — the Richmond District, Sunset District, and Marina — salt-air exposure and high humidity are additional concerns. Corrosion-resistant hardware and vinyl or fiberglass frames hold up better than aluminum in coastal conditions. Condensation resistance also matters: dual-pane construction with insulated spacers reduces interior surface condensation during foggy mornings.
All windows supplied and installed are Title 24 compliant and ENERGY STAR certified for the Western climate zone.
Best time to schedule: April–June. The dry season before summer fog rolls in gives contractors the clearest schedule, and most residential projects complete in a single day.

Common Questions
Window Replacement FAQ — San Francisco
Answers from real Bay Area window contractors.
How much does window replacement cost in San Francisco?
Costs depend on material, window count, and install type. San Francisco's multi-story homes, non-standard Victorian and Edwardian window sizes, and tight contractor supply push costs above the Bay Area average. Use our pricing calculator for a real estimate in 60 seconds — no contact info required.
What window brands are most popular in San Francisco?
The contractor we connect you with installs Milgard, Anlin, Marvin, and Simonton. For San Francisco Victorian and Edwardian homes with non-standard window sizes, Marvin is frequently specified for custom sizing and wood-clad authenticity. Milgard and Anlin are popular for standard-size retrofits in flats and condos.
Do I need a permit to replace windows in San Francisco?
Yes — most replacements require a building permit from the City of San Francisco Department of Building Inspection. The contractor we connect you with pulls the permit and schedules the required City inspection. You don't need to do anything.
Are energy-efficient windows worth it in San Francisco?
Yes. San Francisco's fog-dominant climate means moisture resistance and thermal insulation are equally important. Low-E glass, dual-pane construction, and quality weatherstripping improve comfort during cool summer days and reduce heating costs in winter.

Window replacement in San Francisco can be done any time of year. Spring and fall are the most popular seasons. The mild climate means crews work comfortably year-round.
