How Much Does New Window Installation Cost in Los Angeles?

New window installation in Los Angeles typically costs $450 to $1,350 per window for a standard vinyl retrofit, with most full-home projects of 8 to 12 windows landing between $4,500 and $14,000 all-in. High-end frame materials like fiberglass or wood, plus premium glass packages for LA’s heat and sun exposure, push per-window costs toward $1,800 to $3,200. These are 2026 market numbers for licensed, insured installers working in LA proper, from the Westside to the Valley.

The spread is wide because Los Angeles isn’t one market. A 1930s Spanish Revival in Highland Park with original wood sash needs a different installation method than a 1990s stucco tract home in Porter Ranch. We’ll break down exactly what drives the price, what you should expect to pay by window type, and where homeowners overspend without realizing it.

Key Takeaways

• Typical LA window installation runs $450 to $1,350 per window for vinyl; premium materials cost $1,800 to $3,200 per window.
• Retrofit installation (keeping the existing frame) saves $150 to $400 per opening versus full-frame replacement.
• Energy-efficient glass packages add $80 to $250 per window upfront, but typically cut cooling costs in LA by 12% to 20% annually.
• Most Los Angeles homes need 8 to 12 windows replaced; full projects average $4,500 to $14,000 before any rebate.
• LADWP offers rebates on qualifying energy-efficient windows; we’ll cover current programs below.
• Hale Windows Los Angeles puts the written price in your hands before any work starts. Call (213) 269-5559 for a free estimate.

New Window Installation Cost Breakdown (2026)

The table below reflects what we’re seeing on jobs across Los Angeles in 2026, from Silver Lake to Sherman Oaks. These are realistic installed prices, including labor, materials, trim, caulking, and haul-away. Prices assume a standard double-hung or horizontal slider opening and typical LA stucco or wood-siding construction.

Labor in Los Angeles runs $75 to $130 per hour for a two-person crew, and a standard retrofit takes 45 minutes to 2 hours per opening. Full-frame replacement is slower, 2 to 4 hours per window, because the crew has to cut out the old frame, inspect the rough opening, install flashing, and rebuild the interior trim. That labor difference is the single biggest reason retrofit pricing consistently lands lower than full-frame.

Whole-Home Project Costs in Los Angeles

Most single-family homes in LA have 8 to 15 windows, depending on the year built and the architectural style. Here’s what a complete project typically costs:

• 8 vinyl retrofits, standard grade: $3,600 – $7,200
• 10 vinyl retrofits, mid-grade with low-E glass: $5,500 – $11,000
• 12 full-frame vinyl replacements: $7,200 – $14,400
• 10 premium vinyl or fiberglass, full-frame: $10,000 – $22,000
• Custom wood windows on a hillside home (Bel Air, Mount Washington): $15,000 – $35,000

Hillside homes with difficult access and second-story work add 10% to 25% to labor. A first-floor stucco house in the flats of Mid-City is about as straightforward as LA window work gets. A canyon house in Laurel Canyon or Beachwood Canyon with no direct access to the back elevation will cost more, not because the windows are different, but because the crew is working from ladders, scaffolding, and carrying glass up switchback stairs.

Glass Package Upgrades and What They Cost

Glass upgrades are where LA homeowners can get real value for the money. Standard double-pane glass runs $0 to $50 extra per window over the base unit, but here’s what you can add:

• Low-E coating (a thin metallic layer that blocks heat while letting light through): $40 – $110 per window. In LA’s sun-driven climate, this is the single best upgrade you can make. It cuts solar heat gain visibly, especially on west- and south-facing windows.
• Argon or krypton gas fill between panes: $35 – $90 per window. Adds insulation value and reduces heat transfer.
• Impact-rated glass (PGT or CGI lines): $300 – $700 per window premium. Required in some wildfire-adjacent and high-wind zones, and increasingly requested in the hills where fire risk is top of mind.
• Acoustic glass (laminated, for traffic noise): $180 – $400 per window. Worth it on busy corridors like Sunset Boulevard, Highland Avenue, or anywhere near the 101, 405, or 10 freeways.
• Triple-pane glass: $150 – $350 per window. Rarely necessary in LA’s mild winters, but some homeowners choose it for noise reduction.

What Affects New Window Installation Pricing in Los Angeles

• Retrofit vs. full-frame replacement. Retrofit inserts a new window into the existing frame. It’s faster, cheaper, and usually the right call if the frames are square and dry. Full-frame removes everything to the studs. You choose full-frame when frames are rotted, termite-damaged, or when you want to change the window size or style. In older LA housing stock, like the 1920s bungalows of Eagle Rock or Jefferson Park, full-frame is often unavoidable.
• Home age and frame condition. Pre-1970 homes in LA frequently have dry rot around original windows, especially in coastal areas like Playa del Rey or San Pedro where marine air accelerates wood decay. If we find rot, the repair adds $150 to $500 per opening, and it’s not optional. You can’t set a new window into a frame that’s falling apart.
• Wall construction. Stucco-over-wood-frame, standard throughout the Valley and most of LA, is the easiest and least expensive to work with. True brick or masonry, rare but present in some older multi-family buildings downtown, adds labor. Post-and-beam hillside construction with big custom openings, common in the Hollywood Hills, pushes pricing into custom territory fast.
• Window size and shape. Standard rectangles are cheap because they’re manufactured at scale. Arched, round, triangular, or oversized picture windows get custom-fabricated, and the price jumps 40% to 100% per unit. A 6-foot by 6-foot fixed window in a loft conversion in the Arts District is not the same job as a 3-foot by 4-foot slider in a rental unit in Van Nuys.
• Permit requirements. The City of Los Angeles requires a building permit for window replacement when you’re changing the size of the opening or doing structural work. Retrofit replacement into an existing opening usually doesn’t require one. If a permit is needed, expect $150 to $600 in city fees plus the installer’s time to pull and close it. Responsible contractors build this into the written quote. If someone tells you permits are never needed, get a second opinion.
• The brand you choose. We install and service eight professional-grade lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. A builder-grade vinyl window from a home center and a PGT impact-rated vinyl window are not the same product, and the price reflects it. The right approach is matching the product to the house and the exposure, not pushing one brand because it’s what’s in the warehouse.

What Most LA Homeowners Don’t Expect

Two line items catch people off guard in Los Angeles more than any others. The first is stucco repair. Full-frame replacement into stucco walls often requires patching the exterior stucco around the new window. That’s another $100 to $250 per window unless you’re planning to paint or re-stucco anyway. The second is interior trim replacement. When the old window comes out, the interior casing often can’t be reused, especially if it was painted over multiple times or installed with the original construction. New casing adds $40 to $120 per window. A written quote should include every one of these line items so there are no surprises.

Vinyl vs. Aluminum vs. Fiberglass vs. Wood: What You’ll Actually Pay in LA

Los Angeles is not a one-size-fits-all window market. The 1920s Spanish Colonial in West Adams wants a different product than the 1970s stucco box in Reseda. Here’s what each material really costs, and who should choose it.

Vinyl: The Workhorse

$450 to $1,550 per window installed. Vinyl is the most common window type in Los Angeles for good reason. It’s affordable, it never rots, it requires zero maintenance, and modern vinyl with low-E glass handles LA’s heat well. The downside is aesthetics: vinyl frames are thicker than aluminum, which means less glass area, and they don’t look right on every architectural style. On a mid-century modern in Palm Springs, sure, but on a 1920s Spanish or a 1950s ranch in Tarzana, vinyl can look like what it is: a budget product. We install vinyl from PGT, CWS, and ECO Window Systems for homeowners who want the price advantage without giving up a professional-grade product.

Aluminum: The Condo and Mid-Century Choice

$520 to $1,050 per window installed. Aluminum frames are thin, strong, and low-profile, which makes them the default choice for mid-century modern homes and most condo buildings in LA. The 1960s tower in Westwood with floor-to-ceiling windows? That’s aluminum. The tradeoff is thermal performance: bare aluminum conducts heat, so these units need a thermal break, a plastic insulator inside the frame, to meet California’s Title 24 energy code. A non-thermally-broken aluminum window is cheaper up front but will bake a west-facing room in August. We install ES Windows and Mr-Glass aluminum products with thermal breaks for exactly this reason.

Fiberglass: The Upgrade Path

$850 to $1,550 per window installed. Fiberglass is the strongest frame material available, expands and contracts at nearly the same rate as glass, and holds paint better than vinyl or aluminum. It’s the right product when you want the durability of vinyl with better looks and higher performance. Homes in the hills, where temperature swings between canyon mornings and midday sun are severe, get real benefit from fiberglass stability. The price premium over vinyl averages $200 to $400 per window.

Wood: The Character Choice

$1,250 to $2,450 per window installed, and often more. Wood windows are the only correct choice for many historic Los Angeles homes. A 1920s Spanish Colonial Revival in Hancock Park or Windsor Square, a Craftsman bungalow in Pasadena: these houses need wood windows to look right, and the architectural review boards in LA’s Historic Preservation Overlay Zones often mandate it. Wood costs more, requires exterior maintenance every 5 to 7 years, and isn’t as energy-efficient as fiberglass unless you spec clad wood, with a coated metal exterior over the wood core. Clad wood adds $300 to $600 per window.

LA Energy Codes and Rebates: What Affects Your Bottom Line

California’s Title 24 energy code applies to every window replacement in Los Angeles. Replacement windows must meet minimum U-factor and Solar Heat Gain Coefficient (SHGC) standards, which measure insulation value and the ability to block solar heat. In practice, this means double-pane glass with a low-E coating is the baseline for most installations, and single-pane windows can’t be legally installed in replacement applications. You don’t need to memorize the code, but you should know that a window that doesn’t meet Title 24 can’t be legally sold here. Any reputable installer specs compliant products as the starting point.

LADWP offers rebates on energy-efficient windows through its residential efficiency programs, typically $1.50 to $3.00 per square foot of qualifying glazing, with total rebates for a full-home project running $200 to $800. The exact rebate amount changes by program year and depends on the specific glass package. We make it a point to tell every customer which of our products qualify, and the rebate is built into the discussion, not hidden as an afterthought. The home team at Hale can walk you through current LADWP program terms when we quote your project.

How to Save on New Window Installation

The most effective way to control cost in Los Angeles is to replace all windows in one project rather than a few at a time. Mobilizing a crew, pulling permits, and handling waste disposal carries fixed costs that get spread across every window. A single retrofit might cost $650. Eight retrofits in one visit usually average $500 to $550 per opening. It’s the same crew, same day, same truck.

• Choose retrofit over full-frame when the frames are sound. You save $150 to $400 per window, and in many LA homes the original frames are in fine shape. We inspect before we quote and only recommend full-frame when it’s genuinely necessary.
• Spec the right glass for each exposure. A north-facing window in Santa Monica doesn’t need the same solar-heat-blocking glass as a west-facing window in Sherman Oaks. Matching glass packages to exposure saves you $80 to $200 per window on glass you don’t need.
• Don’t pay for triple-pane in LA. Our winters are mild. Triple-pane adds $150 to $350 per window and delivers almost no energy benefit in this climate unless you’re directly on a freeway and prioritizing noise reduction.
• Get the full written price before signing anything. Every Hale Windows Los Angeles quote is a written, itemized price delivered before any work begins. No deposits for material “maybe” prices, no vague allowances, no surprises on the final invoice. If it’s not on the written quote, it’s not on the bill.
• Ask whether your project qualifies for a rebate. LADWP money is real, and many homeowners leave it on the table because the installer never brings it up.

And a word on the cheapest quotes: in Los Angeles, a window quote that’s 40% below the market is not a deal. It’s a signal that someone is cutting a corner you won’t see until the first rain. Cheaper installers skip flashing, use undersized shims, or install non-compliant glass and hope the inspector doesn’t look. The fix costs more than the savings. Every installation we do at Hale carries the 365-Day Done Right Promise. If it’s not right, we make it right, no argument needed.

Is It Cheaper to Repair or Replace a Window in Los Angeles?

In most cases, replacement wins when the window is more than 20 years old, has failed seals, or is single-pane. A single-pane aluminum window in a 1970s home in the Valley is letting heat in and AC out, and the energy cost compounds every summer. Repair makes sense for minor issues: a broken sash cord, a bad latch, a cracked pane where the rest of the window is sound. A full repair, including glass replacement and hardware, runs $150 to $450 per window. A replacement of that same window is $450 to $900. If the window has multiple problems or visible frame damage, replacement is the better money. Call (213) 269-5559 and we’ll tell you straight which path makes sense for your house.

Who Should Install Your Windows in Los Angeles?

The person arriving at your door matters as much as the window going into your wall. That’s a statement we built this company around, because we understand that opening your home to a stranger is a genuine concern. Many of our customers are home alone during the day, parents with young kids, or older homeowners who’ve had enough bad experiences with contractors.

Every Hale technician operates under the Threshold Standard. That means five specific things: a background check, identity verification, a uniform, a photo badge, and a pre-announcement, you get the technician’s name and photo before the visit, so you know exactly who is at the door before you open it. Not “a technician will be there between 9 and 3.” A specific person, identified by name and photo, arriving at a specific time.

Spencer Odell, who leads our installation teams, has spent years in Los Angeles windows and doors, and he’s built the crew around a simple rule: do the work as if your own mother were going to inspect it. That’s not a slogan. It’s the standard for what leaves our shop.

We install and service eight professional-grade product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Whether your house calls for impact-rated vinyl in a fire zone, thermally-broken aluminum for a mid-century condo, or wood-clad for a historic restoration, we match the product to the house. We’re not a general contractor doing windows on the side, and we’re not a big-box installer cycling through subcontractors. Since 2009, we’ve been an independently owned and operated windows-and-doors company, part of the Threshold Group family of home-service brands.

Every job includes a written price before any work starts. Every repair carries a written guarantee; if a repair fails, the second visit is free. And every installation is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right. No argument needed, no fine print, no chasing us for a callback. If you’re comparing quotes, compare the guarantee language too. Not every Los Angeles installer offers one, much less puts it in writing.

FAQs – New Window Installation Cost

How much does it cost to install one window in Los Angeles?

One standard vinyl retrofit window in Los Angeles typically costs $450 to $900 installed, including labor, materials, and haul-away. A full-frame replacement of the same window runs $600 to $1,200. Premium materials like fiberglass or wood push a single window to $850 to $2,450. For an exact number on your opening, call (213) 269-5559 for a free written estimate.

Can you install windows the same day?

For most standard retrofits, yes. An 8-window retrofit project on a typical LA home is usually completed in one day by a two-person crew. Full-frame replacement takes longer, typically 2 to 3 days for a whole home. When you call Hale Windows Los Angeles, we’ll give you a real schedule along with the written price, and the crew shows up when we say they will.

Do I need a permit for window replacement in Los Angeles?

Retrofit window replacement, where the new window fits into the existing frame without changing the opening size, generally does not require a City of Los Angeles building permit. If you’re changing the size or shape of the opening, or doing structural work, a permit is required and adds $150 to $600 in city fees. If your installer says permits are never needed, get a second opinion. Call (213) 269-5559 and we’ll tell you what applies to your specific project.

Are expensive windows worth it in Los Angeles?

Low-E double-pane windows, which cost $500 to $1,200 per window installed in LA, typically cut cooling costs 12% to 20% annually in our climate. The payback period on a whole-home window project in Los Angeles averages 6 to 12 years depending on your AC usage, your current window condition, and your sun exposure. Homes with west-facing windows in the Valley see faster payback than shaded canyon homes. The value isn’t only energy savings; it’s also comfort, noise reduction, and resale performance.

How much does window installation cost for a 10-window house in Los Angeles?

A 10-window project using standard vinyl retrofits in Los Angeles typically costs $4,500 to $9,000 before LADWP rebates. Full-frame replacement for the same 10 windows runs $6,000 to $12,000. If you choose premium vinyl or fiberglass, expect $8,500 to $15,500. The only way to get a real number for your house is to have someone look at the actual windows. We provide written estimates at no charge. Call (213) 269-5559.

What’s the most cost-effective window for a Los Angeles home?

A vinyl retrofit window with a low-E glass package is the value leader in Los Angeles at $490 to $950 per window installed. You get Title 24 compliance, meaningful heat rejection for summer afternoon sun, and a product that’ll last 25+ years without repainting or refinishing. If your frames are in good shape and you’re not changing sizes, this is the package that makes the most financial sense for the widest range of LA homes.
