AfterHow Much Does New Window Installation Cost in Los Angeles?
New window installation in Los Angeles runs $650 to $1,600 per window installed for most standard vinyl or aluminum units, with full-house projects typically landing between $9,500 and $28,000 depending on count, glass package, and whether we’re working around original 1920s framing or a newer stucco wall. The city’s extreme temperature swings – 100°F July afternoons in the Valley, 55°F mornings in Santa Monica – mean the glass package matters more here than in most markets, and that’s reflected in the numbers below.
Westlight Windows & Doors gives every Los Angeles homeowner a written price before a single screw turns. No door-step revisions, no “we found rot” math games. This guide breaks down what you’ll actually pay in 2026, by window type, by neighborhood, and by what drives the cost up or down.
Key Takeaways
- Standard single-hung vinyl: $650-$950 installed per window in Los Angeles.
- Impact-rated glass (required on many Pasadena and Santa Monica hillside retrofits): add $250-$500 per window.
- Full-house replacement (10-18 windows): $9,500-$28,000 typical range.
- Wood-frame homes in Highland Park and Eagle Rock often need new trim and sill work: budget an extra $150-$400 per opening.
- Every quote we give is written, dated, and locked before work starts.
New Window Installation Cost Breakdown (2026)
Below are installed prices – window, labor, flashing, sealing, trim touch-up, and haul-away included. These are the real numbers we quote in Los Angeles, not national averages pulled from a database.
| Window Type | Price Range (Installed) | Best For |
|---|---|---|
| Single-hung vinyl (standard) | $650 - $950 | Bedrooms, hallways, most interior rooms |
| Double-hung vinyl | $800 - $1,200 | Older craftsman homes where both sashes open |
| Sliding glass vinyl | $1,100 - $1,900 | Patio doors, wide living-room openings |
| Casement / awning | $950 - $1,600 | Kitchens, bathrooms, hillside homes needing max ventilation |
| Bay / bow window | $2,800 - $5,500 | Front facades, view lots in the Hollywood Hills |
| Aluminum (impact-rated, PGT or CGI) | $1,200 - $2,200 | Coastal zones, fire-rated corridors |
| Custom wood-clad (ES Windows, CWS) | $1,500 - $3,200 | Historic districts, architect-led renovations |
| Full-house package (10-18 windows) | $9,500 - $28,000 | Whole-home replacement, best per-window pricing |
Installation labor alone runs $250-$450 per opening in Los Angeles, higher than the national average because of stricter seismic flashing requirements, older housing stock, and the simple cost of getting materials through the city. Glass upgrades sit on top of that figure, not inside it. Entry doors, when paired with a window project, start around $2,400 installed for a Therma-Tru steel or fiberglass unit.
What a Typical Los Angeles Job Looks Like
A 1,600-square-foot Craftsman in Highland Park with 12 original double-hungs runs about $14,500 to $19,000 to replace with energy-efficient vinyl, including new sill work on four openings where the 1920s wood had gone soft. A 1990s tract home in Northridge with 10 builder-grade aluminum windows runs $9,800 to $13,000 because the framing is square and the swap is clean. A hillside home in Sherman Oaks facing the Sepulveda Pass wind corridor almost always gets impact-rated PGT or CGI glass, which pushes a 14-window job to $21,000-$27,000.
What Affects New Window Installation Pricing in Los Angeles
Six factors move the price the most. Here’s what we see on estimates across the city.
- Glass package. Low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) is standard on most of our lines. In Los Angeles, where UV damage to floors and furniture is real, we usually recommend a solar-heat-gain rating below 0.30 on west-facing windows. Adding argon fill and a second low-e coat runs $80-$180 more per window and pays back fast in summer cooling.
- Impact-rated requirements. Homes in wildfire-prone hillside zones and parts of Santa Monica’s coastal overlay often need impact-rated glass to pass inspection. PGT and CGI make units rated for both wind-borne debris and fire exposure. Budget $250-$500 per window above standard.
- Framing and trim condition. Los Angeles has a lot of 1920s and 1930s housing. Original wood sills in neighborhoods like Echo Park and Eagle Rock are frequently soft from decades of marine-layer moisture. We replace them, but it’s real labor and real material – $150-$400 per opening. We flag it in the written quote, not after the fact.
- Number of windows. Per-window pricing drops as the count rises. A single window might quote at $1,050; the same window inside a 15-window package often lands near $780. Setup, disposal, and permit handling spread across more units.
- Permits. The City of Los Angeles Department of Building and Safety requires a permit for replacement windows on most residential projects. Fees vary by valuation, but typical single-family jobs run $180-$420. Westlight pulls the permit and handles inspection coordination as part of the job.
- Access and story. Second-story windows, tight side yards in Silver Lake, and hillside lots where the truck can’t park close all add labor. We note access surcharges in the written price before we start, so nobody’s surprised the morning of.
Window Styles and What They Cost in Context
Single-hung remains the Los Angeles workhorse because it’s simple, seals well, and costs less than double-hung. Double-hung matters in older Craftsman and Spanish Colonial homes where the architecture calls for two operating sashes – the extra $150-$250 per unit is aesthetic and functional, not structural. Casements shine in kitchens and hillside homes where you want max airflow with a crank instead of a lift. Bay and bow windows are a facade decision as much as a cost one, and they’re where we see the widest price swings because the framing has to be built out and finished.
Material choice tracks with the home. Vinyl dominates inland and Valley replacements for value. Aluminum, particularly impact-rated PGT and CGI, dominates coastal and fire-corridor jobs. Wood-clad from ES Windows and CWS shows up on architect-led renovations and historic districts where the look has to match what was there in 1928. We carry eight manufacturer lines, including ECO Window Systems, Mr-Glass, and ViewLux, so the product gets matched to the house instead of the house being forced into one brand.
How to Save on New Window Installation
The single biggest saver is bundling. Going from 3 windows to 12 typically cuts per-window cost by 20-30% because setup, disposal, and permit overhead spread across more units. If you have a two or three year plan, price the whole house now and phase it – we lock the written price for the phased schedule.
Beyond bundling:
- Time the project to the shoulder seasons. Late winter and early spring (February-April) are slower for window installation in Los Angeles. We don’t run promotions, but our crews are more available, and scheduling is easier, which matters if you’re working around tenants or a home office.
- Handle the interior painting yourself. We caulk and seal, but finish-painting the interior trim is optional on our quotes. Rolling it yourself saves $60-$120 per window.
- Skip the grid pattern on non-street-facing windows. Grids add cost and cut light. Keep them on the facade, drop them in the back.
- Ask about return-to-stock and overstock lines. ViewLux and Mr-Glass occasionally have standard-size units available at reduced cost. We’ll tell you if a size matches.
- Get the written price and hold it. Our free estimate comes with a locked, dated price. That protects you from the “we found something at the door” conversation other contractors have. Call (903) 354-7134 to schedule – a live person answers, day or night.

Why the Cheap Quote Usually Isn’t
A $450-per-window quote in Los Angeles usually means one of four things: no permit, no flashing detail, builder-grade glass with no low-e, or a labor pool paid under the table. Any of those four turns into a failed seal within a season or two. Our 365-Day Done Right Promise exists because we’ve been called to fix other contractors’ work more times than we’d like. If our install fails within the guarantee period, we come back and fix it at no charge. The guarantee is written and handed to you at job completion.
FAQs - New Window Installation Cost
How much does new window installation cost in Los Angeles in 2026?
Most single-window installations in Los Angeles run $650 to $1,600 installed. A 12-window whole-house project typically lands between $12,000 and $22,000 depending on glass package, access, and whether the original framing needs repair. Every Westlight quote is written before work begins – call (903) 354-7134 for a free estimate.
Is it cheaper to repair or replace a window in Los Angeles?
Repair is cheaper when the problem is a single failed seal, a stuck sash, or a broken crank – usually $150 to $450. Replacement makes more sense when the frame itself is soft, the window is single-pane and leaking air, or more than one component has failed. Once a repair bill climbs past $500 on a window older than 20 years, replacement is usually the better financial call, especially with Los Angeles cooling costs. We’ll tell you honestly which one you’re looking at during the free estimate.
Can you install windows the same day in Los Angeles?
Standard single-hung and double-hung swaps can often be done same-day on a small job, usually 3 to 6 windows in one visit. Larger projects and any job needing a permit inspection get scheduled across one to three days. Call (903) 354-7134 and we’ll give you a real arrival window, not a four-hour “sometime Tuesday.”
Do I need a permit for new windows in Los Angeles?
Yes, most residential window replacements in the City of Los Angeles require a permit from the Department of Building and Safety. Fees typically run $180 to $420 for a single-family project, and the work has to pass inspection. Westlight pulls the permit for you and handles the inspection coordination. Jobs without a permit can trip up a future home sale, so we don’t skip it.
What’s the price difference between standard and impact-rated windows in Los Angeles?
Impact-rated PGT or CGI windows run $250 to $500 more per window than standard vinyl in the Los Angeles market. Homes in coastal overlay zones and wildfire-prone hillsides often require them. If your neighborhood is affected, it’s not optional – it’s a code item, and it’s in the written quote.
How long does new window installation take in Los Angeles?
A typical single-family job takes one to three days on site. A 12-window whole-house install is usually two days, with a return visit for final trim and inspection. Long-lead items like custom wood-clad ES Windows can add three to six weeks to the schedule before install day.
Why Homeowners in Los Angeles Choose Westlight
Westlight Windows & Doors has been installing windows and doors as an independently owned and operated Kingswell location since 2009. We carry eight manufacturer lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – which means we match the window to your house rather than pushing one brand at every job. Every project runs on the Kingswell Guarantee and The Kingswell Way: say the price before the work, show up in the window we gave you, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.
That last one is the 365-Day Done Right Promise. If the work isn’t right, we return and correct it at no charge. Background-checked, uniformed technicians handle every job, so you know exactly who’s walking through the door. A live person answers the phone 24 hours a day, seven days a week – not a voicemail box, not a chatbot. Owen Satterfield leads our team, and he’ll personally review any estimate you’re unsure about.
