California Title 24 (Building Energy Efficiency Standards) sets strict requirements for window U-factor and SHGC — all replacement windows must meet these standards regardless of home age.
The average California homeowner spends $400–$900 per window installed. Bay Area premium: $600–$1,200. Whole-house (14 windows): $7,000–$18,000 depending on frame material and glass package.. Costs vary based on window count, frame material (vinyl, fiberglass, wood, aluminum), glass package (double-pane vs. triple-pane, Low-E coating, gas fill), and installation complexity. Getting at least 3 quotes is the best way to ensure competitive pricing.
ENERGY STAR window rebates available through PG&E, SCE, SDG&E, and SMUD. Typical rebates: $25–$100 per window. Title 24 compliance required for all window replacements.
CA climate varies dramatically: Bay Area needs good U-factor for cold fog; SoCal needs low SHGC to block solar heat; High Desert needs triple-pane for temperature swings.
CA Contractor's License Board (CSLB) Class C-17 (Glazing) or B (General Building) license required.. Always verify your contractor's license before signing any contract. Ask for proof of general liability insurance and workers' compensation coverage.

The final price depends on the number of windows, frame material, glass package, and whether full-frame or insert replacement is needed. Getting multiple quotes is the best way to find fair pricing in your market.

Most window replacement projects take 1–3 days for a typical home (8–15 windows). Insert replacements (reusing existing frames) are faster than full-frame replacements.
Low-E double-pane (Title 24 compliant) is the most popular choice in California. Vinyl is low-maintenance and cost-effective. Fiberglass is more durable but costs 20–30% more. Wood offers the best aesthetics but requires painting or staining every few years.
Permit requirements vary by municipality. In-kind replacements (same size, same location) often don't require a permit, but structural changes always do. Your licensed contractor should pull all required permits — be cautious of contractors who suggest skipping this step.
