Not sure if you're ready to replace your windows?
For a full window replacement, the most common frame materials are vinyl, fiberglass, wood, and composite. Within each, you choose the style, double-hung and casement being the most common, and the glass package that suits your climate. Many homeowners bundle window replacement and door replacement, since both are handled by the same crews.
Repairing a window makes sense for a failed seal, damaged hardware, or a single broken pane on a unit that is otherwise sound. Replacing the whole window is usually the better call once several units are drafty, fogged, or painted shut.

Los Angeles climate: mild, dry summers, wildfire risk in foothill zones.
Coastal mild temperatures mean the efficiency case for new windows is often modest compared to harsher climates. In the Pacific Northwest, focus on Washington/Oregon energy code compliance (U-factor ≤ 0.30); in California, noise reduction and wildfire-smoke-season ventilation are often the bigger win.

Installed cost in Los Angeles runs roughly 5% above the national average for this trade. Here's how we got to that number.
Project costs include three main components: labor, materials, and overhead. Material ships at national prices no matter where you live, and overhead is fairly consistent as well. So the main pricing difference between metro areas is labor costs. This is why a quote from a high-wage metro is rarely as far above the national average as people expect.
To get Los Angeles labor costs, we compared the average hourly wage in the Los Angeles-Long Beach-Anaheim, CA area to the national average hourly wage for this trade. (source: US Bureau of Labor Statistics, Occupational Employment and Wage Statistics, May 2025)
We found that the local trade wages sit about 20% above the national figure. Labor costs typically make up about 26% of a window replacement project cost, so the weighted difference between Los Angeles and national averages is +5%. See methodology and sources.
It depends on the scope of your project, so you should talk to the permitting authority to find out what your project needs. In general, Los Angeles permitting is complex compared to other metros we cover.
Permitting for building goes through LA Department of Building and Safety (LADBS). Online at ladbs.org. Title 24 energy compliance required for window replacement. Coastal Commission rules apply in beach areas.
You should ask each contractor if they pull the permits for you and if the fee for pulling permits is included in their quote. Also, tell them you need to see the written, approved permit before work starts.
California requires a state license for window replacement work. (source, verified as of 2026-08-12) What that means and how to verify a contractor in California →
