Window Replacement Cost in Los Angeles 2026 — Full Price Guide

Window Replacement Cost in Los Angeles, CA — 2026

Window replacement is one of the most common home improvement projects in greater Los Angeles — driven by aging single-pane windows that fail California’s Title 24 energy code, outdated aluminum sliders that compromise home security, and the dramatic improvement in comfort and noise reduction that modern dual-pane windows deliver. This guide covers the real cost of window replacement in Los Angeles in 2026.

Window Replacement Cost Per Window (Los Angeles, 2026)

Standard Dual-Pane Vinyl Window ($350–$750 per window)

Installed cost including labor. Dual-pane low-E vinyl window in standard sizes (24″x36″ to 36″x60″). Milgard Tuscany Series, Simonton 5500, or equivalent. California Energy Commission certified for Title 24 compliance. For a typical Los Angeles home with 15–18 windows, total project cost: $5,250–$13,500.

Mid-Range Dual-Pane Aluminum Clad or Fiberglass ($650–$1,200 per window)

Installed cost. Aluminum-clad wood or fiberglass frames — stronger profiles, wider glass area, better aesthetics. Milgard Essence Series (fiberglass), Marvin Elevate (aluminum clad), or equivalent. Popular in Culver City, Santa Monica, Pasadena, and Westside homes where visual quality matters. For 15 windows: $9,750–$18,000.

Premium Aluminum or Wood Window ($1,100–$3,500+ per window)

Installed cost. Premium aluminum (Milgard Ultra, Fleetwood, Western Window Systems) or custom wood (Marvin Ultimate) for high-end homes in Beverly Hills, Brentwood, Pacific Palisades, Manhattan Beach. Full-height windows, custom sizes, or steel-look frames. For large-format windows (48″x72″ or larger): $1,800–$6,000+ each installed.

Sliding Glass Door / Patio Door ($1,800–$8,500)

Installed cost. 6-foot sliding glass door (vinyl) to 12-foot multi-panel steel-look door (Fleetwood or Western Window Systems). LA’s outdoor living culture makes patio door quality highly visible and impactful on buyer perception.

Same-for-same replacement (same size, same location) does not require an LADBS building permit. Enlarging window openings (requires structural modification) does require a permit. If your home is in a historic district (HPOZ), exterior window changes require Cultural Affairs review. APLA advises on permit requirements for every window project.

How long does window replacement take?

1–3 days for a full-house window replacement with pre-ordered windows. Custom or large-format window orders have 4–12 week lead times. APLA coordinates material procurement to minimize project duration.
