Window & Door Replacement
in South San Francisco

South San Francisco's mix of 1940s-50s bungalows and hillside homes still run a lot of original single-pane windows. We fit modern, efficient replacements to your home's existing openings, with free measurement and a clean, same-day install for most projects.

South City's older bungalows deserve better than single-pane glass

A lot of South San Francisco's housing stock, especially around Sign Hill and the flatlands below it, dates to the 1940s and 50s. Original single-pane windows in these homes mean higher PG&E bills, condensation on cold mornings, and street noise that carries right through the glass. We replace them with double-pane vinyl or fiberglass windows sized to your exact openings.

South San Francisco FAQ

Common questions from
South San Francisco homeowners

Can you match new windows to my older South San Francisco bungalow?

Yes. Many of South City's bungalows share similar trim details and opening sizes from that era. We measure your existing openings and trim precisely and can spec window styles and grid patterns that match your home's original look, so the replacement doesn't look out of place.

How long does window installation take?

Every project is different, but we always give you a time estimate when we quote, and we’re usually accurate. We work as fast as the job allows without cutting corners. A proper installation takes the time it takes. If a project runs across multiple days, your home is always secured at the end of each day; we never leave openings exposed overnight. After your proposal is signed, product lead times typically run 3–5 weeks depending on what you’ve ordered. Our crew cleans up completely before leaving.

Are there tax credits or rebates for new windows?

Yes. Federal tax credits under the Inflation Reduction Act may apply for Energy Star certified windows and doors installed in your primary residence, worth up to 30% of product cost (up to $600 for windows). PG&E also offers utility rebates for qualifying upgrades. We'll advise you on which products qualify during your estimate.
