Bay Area · Windows & Doors FAQ

Questions Bay Area homeowners ask first.

Start a Bay Area window or door brief. We'll review Title 24, structural feasibility, and write a fixed-scope contract.

  1. What does a Bay Area window replacement cost?
    Full-frame window replacements $1,100–$2,500 per opening installed. Folding-glass wall $1,800–$3,500+ per linear foot.
  2. Do I need a permit?
    Like-for-like vinyl retrofit usually doesn't. Full-frame, header changes, and any structural opening changes do. We pull what's required.
  3. Can you do indoor-outdoor folding walls?
    Yes — NanaWall, LaCantina, and Western, with proper header, drainage track, and finish detail. Common on Peninsula and Eichler remodels.
  4. How long does a whole-house window replacement take?
    Most single-family full-frame replacements run 6–12 working days on site after material delivery. Lead times on custom or folding-glass systems can add 10–18 weeks.
  5. What does Title 24 require for Bay Area window replacements?
    All replacement glazing must meet Title 24 maximum U-factor and SHGC. We specify NFRC-certified product and submit the certificate at permit closeout.
