AfterHow Much Does New Window Installation Cost in Los Angeles?
New window installation in Los Angeles typically costs between $5,310 and $17,700 for a full-home project, with most homeowners paying around $9,000 to $12,000 for standard vinyl or aluminum window replacements. Per-window, expect $650 to $1,200 including labor and materials. These figures reflect 2026 Los Angeles market rates, where labor costs run higher than the national average and permit requirements add $200 to $600 depending on your neighborhood.
At Penhallow Remodeling Los Angeles, we put that number in writing before any work starts. Not a ballpark, not a verbal estimate. A written price you can hold us to, covered by our 365-Day Done Right Promise.

New Window Installation Cost Breakdown (2026)
Here’s what the numbers look like for Los Angeles homeowners in 2026, broken down by window type and project scope. These are the same ranges we use when we sit down at your kitchen table and write your estimate.
| Line Item | Low End | High End | Notes |
|---|---|---|---|
| Standard vinyl window (per window, installed) | $650 | $1,100 | Double-pane, basic size, no structural work |
| Aluminum window (per window, installed) | $800 | $1,400 | Common in mid-century LA homes, slimmer frames |
| Fiberglass window (per window, installed) | $1,000 | $2,000 | Better thermal performance, fewer expansion issues |
| Wood window (per window, installed) | $1,100 | $2,500 | Required for some historic districts like Hancock Park or Angelino Heights |
| Impact-resistant window (per window, installed) | $1,400 | $3,200 | Higher upfront cost, possible insurance discounts |

| Stucco repair and trim work (per window, if needed) | $120 | $450 | Common in older LA homes with cracked stucco surrounding frames |
Those are the numbers. Now let’s talk about what moves them up or down.
What Affects New Window Installation Pricing in Los Angeles
Los Angeles isn’t one housing market. It’s dozens. A 1920s Spanish Revival in Los Feliz has different framing, different stucco, and different permit requirements than a 1980s tract home in West Hills. Here’s what actually changes the price.
- Window material and brand. Vinyl is the affordable workhorse. Aluminum fits the mid-century aesthetic you see across the San Fernando Valley. Wood is gorgeous and required in some designated historic districts. Fiberglass sits in between but handles LA’s temperature swings well. Each step up adds $200 – $1,400 per window.
- Stucco condition around existing windows. Older Los Angeles homes often have cracked or crumbling stucco around window openings. When we remove the old frame, that stucco can come with it. Repairing and re-patching adds $120 – $450 per window. We’ll flag this during the site walk, not after the crew has already cut into your wall.
- Historic Preservation Overlay Zone (HPOZ) requirements. Los Angeles has over 35 HPOZ districts, including Angelino Heights, Hancock Park, and Windsor Square. If your home falls inside one, you’ll need HPOZ review and possibly period-appropriate window styles. Wood windows or specific mullion patterns can push your per-window cost up by 40 – 80%. We handle the paperwork so the permit doesn’t stall.
- Floor level and access. Second-story windows cost more to install safely. If your home is on a hillside lot in Echo Park or Mount Washington with restricted access, expect a 10 – 20% premium for scaffolding and safety equipment.
- Number of windows and total project size. Per-window pricing usually drops slightly as the project grows, because mobilization costs spread out. But a 3-window job in a small Silver Lake bungalow will have a higher per-window cost than a 14-window job in a Cheviot Hills two-story.
- Framing repairs and dry rot. Coastal neighborhoods like Playa del Rey and San Pedro deal with salt air, and older homes throughout LA deal with sprinkler overspray against wooden frames. If we find dry rot during installation, the framing repair runs $150 – $800 per window depending on severity. With our written-price commitment, you’ll know the cost of that repair before we proceed.
Window Installation vs. Window Replacement: What’s the Difference in Cost?
Homeowners often use these terms interchangeably, but they mean different scopes of work with different price tags.
Window replacement means swapping an existing window for a new one inside the same rough opening. The frame, surrounding stucco, trim, and interior casing stay largely untouched. This is the $5,310 – $17,700 range above, and it’s what most Los Angeles homeowners need when they’re tired of drafty single-pane windows or fogged double-panes.
New window installation means cutting a new opening where none existed, or significantly enlarging an existing opening. You might be adding a window to brighten a dark kitchen in Atwater Village, or putting a picture window into a blank wall facing the San Gabriel Mountains. This involves framing, header installation, drywall work, stucco patching, and sometimes structural engineering. Expect to add $1,500 – $4,500 for a single new opening, depending on wall type and whether the wall is load-bearing.
At our new window installation service page, we explain the full scope of what cutting a new opening involves, so there are no surprises on day one.
What Our Window Installation Price Includes
Every window installation estimate from Penhallow Remodeling Los Angeles includes the full scope. Not just the window and the labor. Here’s what’s in the written number.
- The windows themselves, sourced from manufacturers whose warranties we trust. Our materials come from recognized trade brands, and every window carries its own manufacturer warranty alongside our 365-Day Done Right Promise.
- Removal and disposal of your old windows. We haul everything away. You shouldn’t be renting a dumpster on top of paying for installation.
- Flashing and weatherproofing. This is the layer that keeps LA’s winter rains from finding their way into your walls. We don’t skip it, and we don’t charge extra for doing it correctly. It’s standard.
- Interior and exterior trim work. The window doesn’t stop at the glass. Trim, caulking, and touch-up work are included.
- Permit pull and scheduling. We handle the LADBS paperwork and the inspection scheduling. You get a written record and a final sign-off.
- The 365-Day Done Right Promise in writing. If something isn’t right within a year of installation, we come back and fix it at no charge. That’s not a marketing line. It’s on every contract.
How Much Does Window Installation Cost in Different LA Neighborhoods?
Pricing holds fairly steady across Los Angeles because labor and material costs are city-wide. But some neighborhoods carry specific cost factors.
San Fernando Valley (Sherman Oaks, Encino, Northridge, Woodland Hills)
Valley homes tend to be single-story or two-story tract builds from the 1950s through 1980s. Aluminum sliders are common, and replacement is usually straightforward. Expect the lower end of the range: $650 – $900 per window for standard replacements. Valley heat is the main driver here. Homeowners are upgrading to double-pane, low-E glass to cut air conditioning costs during months when Van Nuys regularly hits 95°F.
Westside (Santa Monica, Brentwood, Westchester, Palms)
Westside pricing runs slightly higher due to parking logistics, HOA restrictions in some condo buildings, and older housing stock with non-standard window sizes. Budget $800 – $1,500 per window. Homes within a mile or two of the coast also deal with salt-air corrosion on aluminum frames, which can complicate removal and add time.
Central LA and Eastside (Echo Park, Silver Lake, Los Feliz, Highland Park)
Homes on the Eastside skew older. Many were built before 1940 with wood windows and lath-and-plaster interior walls. Replacement in these homes often requires careful plaster patching and sometimes custom window sizing to match the original openings. Per-window costs here run $850 – $1,700. If you’re in an HPOZ, add review fees and possibly specific window style requirements.
South LA and Inglewood
South LA homes span everything from 1920s bungalows to mid-century builds. The cost driver here is often deferred maintenance. We see more dry rot, more settled framing, more windows that haven’t operated correctly in years. Per-window replacement typically lands between $700 and $1,100, but expect framing repairs to be more common in this area than in newer Valley developments.
Window Materials: What You Actually Need for Los Angeles Weather
Los Angeles has a Mediterranean climate with hot, dry summers, mild winters, and a rainy season that dumps most of our annual precipitation between December and March. Your window material choice should reflect that.
Vinyl Windows: The Workhorse
Vinyl is the most common choice in Los Angeles for good reason. It handles temperature swings well, requires zero painting, and costs the least. A standard double-pane vinyl window runs $650 – $1,100 installed in most LA neighborhoods. The trade-off: vinyl frames are thicker than aluminum, which means slightly less glass area for the same opening size. In smaller bedrooms where every inch of light matters, some homeowners opt for narrower profiles.
Aluminum Windows: The Mid-Century Classic
Aluminum windows are standard in mid-century modern homes, and they’re what many LA homeowners already have. New aluminum frames with thermal breaks cost $800 – $1,400 per window and solve the condensation and heat-transfer problems of older aluminum frames. They offer the slimmest sightlines, which is why many homeowners in the hills above Studio City choose them: the view stays unobstructed.
Fiberglass Windows: The Performance Pick
Fiberglass costs a step up at $1,000 – $2,000 per window, but it expands and contracts at nearly the same rate as glass, which means fewer seal failures over time. That matters in LA, where a hot afternoon followed by a cool ocean breeze at night cycles window frames through constant expansion and contraction.
Wood Windows: The Character Choice
Wood windows run $1,100 – $2,500 per window and are required in some HPOZ districts. They’re beautiful but demand maintenance, especially in coastal areas where moisture takes a toll. For most Los Angeles homeowners, wood makes the most sense when architectural integrity demands it, not as the default pick.
Impact Windows in Los Angeles: Worth It?
Impact-resistant windows cost $1,400 – $3,200 per window installed, roughly double standard vinyl. For most Los Angeles homeowners, they’re unnecessary. Our earthquake risk is much higher than our hurricane risk, and impact windows don’t do anything for seismic events.
However, impact windows do offer three genuine benefits in LA: significant noise reduction (useful near the 405 or the 101), added security against break-ins, and possible discounts on homeowners insurance depending on your carrier and ZIP code. Some insurers in wildfire-adjacent areas like the foothills above Glendale and Pasadena also view impact-rated glass favorably. If you’re considering them, call (213) 277-6578 and we’ll walk through the cost-benefit math for your specific home and insurance situation.
Window Installation Permits in Los Angeles: What They Cost and Who Handles Them
The City of Los Angeles Department of Building and Safety (LADBS) requires a permit for window replacement when the opening size changes or when you’re cutting new openings. Like-for-like replacements in existing openings don’t always require a permit, but the rules vary by scope.
Here’s the practical version: if we’re swapping a window for a window the same size, we may not need LADBS sign-off. If we’re changing window sizes, adding windows, or working in an HPOZ, you’ll need a permit that runs $150 – $500. HPOZ review adds time and possibly additional fees depending on the district.
We handle all permit paperwork for Los Angeles window projects. You shouldn’t be standing in line at LADBS wondering which form goes where. It’s part of the job, and it’s part of the written price.
How to Save on New Window Installation in Los Angeles
You don’t need to cut corners to save real money on window installation. You need to avoid change orders, timing mistakes, and scope creep.
- Replace in phases, but batch smartly. If budget is tight, replace the worst-performing windows first (south-facing windows take the most sun damage in LA) and do the rest later. Per-window pricing on a smaller batch will run slightly higher, but it beats financing a project you can’t afford comfortably.
- Do the whole home at once when you can. The best per-window pricing comes with a full-home project. Mobilization costs, dumpster fees, and permit costs spread across more windows. A 12-window job almost always costs less per window than three separate 4-window jobs.
- Don’t move window locations. Keeping windows in their existing rough openings is the single biggest money-saver. Moving a window or enlarging an opening triggers framing work, drywall, stucco, and often permits. When the existing layout works, keep it.
- Choose materials based on your actual needs, not resale fantasy. Vinyl is the right choice for most LA homes. You don’t need wood windows in a 1970s North Hollywood ranch house unless an HPOZ says otherwise. Put the savings into better glass packages instead.
- Ask for the written price and the written guarantee. The most expensive window project in Los Angeles is the one where the price changes after the first window comes out. At Penhallow Remodeling Los Angeles, you get a written number before work starts, and the number on your contract is the number on your final invoice. That’s The Kingswell Way, established in 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
- Schedule during slower months. Window installation demand in Los Angeles peaks in late spring and early fall when the weather turns and people start thinking about their drafty windows. If you can schedule between November and February, you’ll sometimes find better lead times and more flexibility on pricing.
FAQs – New Window Installation Cost
How much does new window installation cost in Los Angeles?
Full-home window installation in Los Angeles ranges from $5,310 to $17,700, with most homeowners paying $9,000 to $12,000 for 8 – 12 standard vinyl or aluminum windows. Per-window cost including labor and materials runs $650 to $2,500 depending on material, with vinyl at the low end and wood at the high end. Call (213) 277-6578 for a free, written estimate with the exact scope and price for your home.
Is it cheaper to repair or replace windows in Los Angeles?
Repairing a window costs $120 – $600 for common issues like fogged glass replacement, hardware repair, or weatherstripping. But if your windows are more than 20 years old, single-pane, or the frames themselves are failing, replacement usually makes more financial sense. Persistent repair costs add up fast, and old windows are the biggest source of energy loss in most LA homes. We’ll tell you honestly which path makes sense for your specific windows, not which one makes us more money.
How much does a full-house window replacement cost in Los Angeles?
A full-house window replacement for a typical 3-bedroom Los Angeles home with 10 – 12 windows runs $7,500 – $14,000 for standard vinyl or aluminum. Larger homes, custom windows, wood windows, or properties in HPOZ districts can push the total to $20,000 – $30,000. The real driver is material choice and window count, which is why we walk your home with you and itemize every window line by line in your written estimate.
Do I need a permit to install new windows in Los Angeles?
If you’re replacing windows in existing openings without changing the opening size, Los Angeles typically doesn’t require a permit. If you’re cutting new openings, enlarging existing ones, or your home is in a Historic Preservation Overlay Zone, you’ll need LADBS permits and possibly HPOZ review, which adds $150 – $500 in permit fees. We handle the entire permitting process as part of our service.
Can Phenallow Remodeling replace windows the same day?
Standard window replacement in existing openings can often be completed in one day for 5 – 8 windows, assuming framing is sound and no surprises are hiding behind the stucco. Larger projects with custom windows or HPOZ reviews take longer. When we give you a date, it’s a real appointment with a real arrival window, and our technicians arrive in uniform, background-checked, and ready to work.
Does window replacement in Los Angeles add resale value?
Yes, and the return is consistent. Updated windows are one of the top three features Los Angeles buyers notice during walk-throughs, alongside kitchen condition and roofing. For a $10,000 window replacement, expect to recapture roughly 60 – 75% of that cost in resale value, plus the immediate benefit of lower energy bills and a quieter home while you still live there. If you’re on the fence about selling or staying, it’s a project that pays you either way.
