AfterHow Much Does Window Replacement Cost in Los Angeles?
Window replacement in Los Angeles typically costs between $5,310 and $17,700 for a full home in 2026, with most homeowners paying around $9,500 for 8 to 10 standard double-hung vinyl windows including professional installation. The per-window price lands between $530 and $1,770 depending on frame material, glass package, and how much structural work the opening needs. Those numbers cover the realistic range for LA’s housing stock, from 1920s bungalows in Highland Park to mid-century ranches in the Valley.
We’ve been replacing windows across Los Angeles since 2004, and the price you’ll actually pay comes down to five things: window count, frame material, glass efficiency, the condition of your existing frames, and whether your home falls under any local preservation review. We’ll break all of that down below, in plain numbers.
Key Takeaways
- Typical LA window replacement job: $5,310 to $17,700 for a full home, $530 to $1,770 per window installed.
- Vinyl is the most common choice in Los Angeles and costs the least; fiberglass and wood run higher.
- Labor in LA runs $100 to $300 per window, with higher rates for second-story work, stucco repairs, and older homes with non-standard openings.
- Dual-pane, Low-E glass is now required to meet California Title 24 energy standards, which affects baseline pricing.
- Mason Remodeling provides a written price before any work starts, on every project, no exceptions. Call (213) 632-5711 for a free estimate.
Window Replacement Cost Breakdown (2026)
Here’s what window replacement actually costs in the Los Angeles market this year. These are installed prices, meaning they include the window unit, labor, basic trim work, haul-away, and all required flashing and sealing.
| Line Item | Cost Range (Installed) |
|---|---|
| Vinyl double-hung window (standard size, dual-pane) | $530 – $890 per window |
| Vinyl casement or slider window | $590 – $1,060 per window |
| Fiberglass window (dual-pane, Low-E) | $1,060 – $1,770 per window |
| Aluminum window (primarily for mid-century homes) | $590 – $1,180 per window |
| Wood or wood-clad window | $1,180 – $2,360 per window |
| Full-home replacement (8 – 10 windows, vinyl) | $5,310 – $8,860 |
| Full-home replacement (6 – 8 windows, fiberglass or wood) | $9,440 – $17,700 |
| Labor only (installation, per window) | $100 – $300 per window |
| Stucco repair / exterior trim replacement (per window, if needed) | $120 – $470 per window |
| Permits (when required by LADBS) | $150 – $600 total |
A few notes on those numbers. First, Los Angeles has a huge inventory of stucco homes, especially in neighborhoods like West Adams, Leimert Park, and the eastern San Fernando Valley. If the stucco around a window opening is cracked, crumbling, or has been patched poorly in the past, expect to pay a bit more per window for repair so the new flashing seals correctly. Second, homes built before 1978 often have lead paint on the existing window trim, which means your crew needs to follow specific containment procedures. That’s a safety and compliance thing, not a markup trick. Finally, if you’re in a designated Historic Preservation Overlay Zone (HPOZ) like Angelino Heights or Carthay Circle, you may need a Certificate of Appropriateness before replacing windows, and you may be required to match the original material and profile. That can push per-window costs to the upper end of those ranges or beyond.
What Affects Window Replacement Pricing in Los Angeles
- Frame material. Vinyl is the value choice for most LA homes and holds up well in our Mediterranean climate. Fiberglass costs more but expands and contracts less with temperature swings, which matters in inland areas like Woodland Hills or Pasadena where summer afternoons regularly top 100 degrees. Wood windows are the most expensive and require the most maintenance, especially within a few miles of the coast where salt air is a constant factor.
- Glass package and energy efficiency. California’s Title 24 building code sets minimum energy performance standards for replacement windows. Dual-pane glass with Low-E coating is now effectively the baseline, not an upgrade. That is already baked into the price ranges above. If you want triple-pane or laminated glass for noise control near the 405, Century Boulevard, or any of the major surface streets, add roughly $200 to $350 per window.
- Window count and size. This one is obvious but it moves the total more than anything else. A 1920s bungalow in Echo Park might have 6 windows. A 1950s ranch in Van Nuys might have 14. You can do the math, but volume does not automatically mean a lower per-window price. The labor to set, flash, and trim each window is real work whether you do 4 windows or 20.
- Access and elevation. Single-story homes with easy reach to every opening cost the least to work on. Second and third story windows, windows over vaulted stairwells, or openings that require work from a steep sloped roof add labor. If the crew needs scaffolding or a lift to reach an opening safely, that cost is reflected in the estimate.
- Age and condition of the existing frames. Here’s what we see across Los Angeles with real consistency: in older neighborhoods like Silver Lake and Jefferson Park, the original wood frames have been in place for 60 to 90 years. Some are reusable. Many are not. If the frame has rotted, been eaten by termites, or is no longer square, the old window can’t simply be swapped out. The opening has to be reframed, and that’s where per-window costs climb from the $530 range toward the $890 or $1,180 range for vinyl, and higher for other materials.
- Local permitting and HPOZ requirements. A standard same-size replacement in a non-historic home usually does not require an LADBS permit. But if you’re enlarging an opening, adding a new window where none existed, or doing any structural header work, a permit is required. HPOZ properties, as noted above, have additional review layers. In 2026, expect permit fees for window work to run between $150 and $600 total when they apply.
Vinyl vs. Fiberglass vs. Wood: What Do LA Homeowners Actually Choose?
We install all three, and the honest answer is that most Los Angeles homeowners choose vinyl. It’s not because vinyl is the best window ever made. It’s because vinyl hits the sweet spot for our climate, our home styles, and most people’s budgets. Here’s the straight comparison.
Vinyl Windows ($530 – $890 per window)
Vinyl handles LA’s dry heat and mild winters without issue. It never needs painting, it won’t rot, and modern vinyl windows with multi-chambered frames and Low-E glass deliver solid energy performance. The tradeoff is color and profile. Vinyl windows are almost always white or tan, and the frames are thicker than wood. On a Spanish Revival in Los Feliz or a Craftsman in Pasadena, thick white vinyl doesn’t look right. On a 1960s ranch in Granada Hills or a contemporary box in Mar Vista, it looks completely at home.
Fiberglass Windows ($1,060 – $1,770 per window)
Fiberglass is what we recommend when a homeowner wants a slimmer frame profile, better long-term stability, and the option of darker colors without the warping risk that dark vinyl has in direct sun. In neighborhoods like Sherman Oaks or Studio City where afternoon sun exposure is brutal on the west-facing side of the house, fiberglass makes sense. It costs roughly double what vinyl costs, and for most people, it’s a want rather than a need.
Wood and Wood-Clad Windows ($1,180 – $2,360 per window)
Wood windows are the right call for historic homes, HPOZ properties, and homeowners who care about the interior look above all else. The interior side of a wood window can be stained to match baseboards and trim, which matters in older homes where the interior woodwork is original. The downside in Los Angeles is the sun and the salt air. Wood windows within five miles of the coast will need more frequent refinishing than the same windows further inland. That’s a maintenance cost you should factor in honestly.
Window Replacement Cost by Los Angeles Neighborhood
Prices in the ranges above assume standard conditions. Here’s what changes by area, based on what our crews actually encounter.
- San Fernando Valley (Woodland Hills, Encino, Northridge, Van Nuys): Lots of single-story mid-century homes with standard openings. These are the most predictable jobs and usually land in the lower half of the price range. The heat is the main factor, so dual-pane Low-E glass is doing real work out here.
- Central LA and Westside (Koreatown, West Adams, Culver City, Mid-City): Older housing stock, a mix of stucco and wood siding, and a high percentage of homes from the 1920s through 1950s. Expect more frame repair, more lead paint protocols, and more non-standard opening sizes. Prices lean toward the middle of the range.
- Coastal communities (Santa Monica, Venice, Long Beach, San Pedro): Salt air, marine layer moisture, and strict local building rules in some of these cities. Aluminum and wood frames corrode faster here, so replacements in these areas skew toward fiberglass or high-end vinyl. Labor runs slightly higher due to permitting complexity in some municipalities.
- Historic and HPOZ districts (Angelino Heights, Hancock Park, Carthay Circle, University Park): If you’re in one of these zones, assume the upper end of the range or slightly above. Matching requirements are real, and the review process adds time. We help homeowners through this, but it is not a quick process.
How to Save on Window Replacement Without Cutting Corners
- Do all the windows at once. The biggest single cost driver is mobilizing a crew for a small job. If you divide the work over three separate visits, you pay three mobilizations. If you do them all at once, you pay one.
- Replace in the off-peak months. Window replacement in Los Angeles doesn’t really have a slow season the way roofing does in cold climates, but demand does dip slightly in November and December. Scheduling then may get you faster availability, though it won’t change the price materially.
- Keep your window sizes standard. If the windows you’re replacing are already standard sizes, you’re in good shape. Custom sizing adds cost. When we encounter non-standard rough openings, we always check whether a standard unit can be fitted with minimal adjustments before jumping to custom ordering.
- Check for utility rebates. LADWP and SoCal Edison occasionally run rebate programs for energy-efficient window upgrades, though availability changes year to year. It’s worth a five-minute check on their websites before you sign a contract.
- Get a written price up front. This is the thing we tell every homeowner, whether or not they hire us. The number you get on the phone means nothing. The number on the written proposal is the one that matters. At Mason Remodeling, we deliver a written price before any work starts, on every project, every time. No verbal estimates that grow on the final bill. Call (213) 632-5711 and you’ll get a real number, in writing, with no obligation.
Why Window Replacement Costs What It Costs in Los Angeles
A window replacement quote has three parts: the window unit itself, the labor to install it, and any surrounding work the opening needs. When someone quotes you $300 per window and someone else quotes you $700 per window for what sounds like the same job, one of three things is happening. Either the cheaper quote is for a lower-grade window, the cheaper quote doesn’t include stucco or trim work that the other one does, or the cheaper quote is going to change once the crew actually opens up the wall. A written price on a detailed proposal protects you from all three.
The other thing that runs through every Los Angeles window job is California’s energy code. Title 24 requires replacement windows to meet specific U-factor and Solar Heat Gain Coefficient ratings. The windows have to perform. That’s not a regulation angle you can opt out of, and it’s a good thing for your cooling bill. It does mean that the cheapest possible window on the market is not a legal option for a permitted replacement in this state.
FAQs – Window Replacement Cost in Los Angeles
How much does it cost to replace one window in Los Angeles?
A single standard-size vinyl window in Los Angeles costs $530 to $890 installed in 2026. That includes the window, installation labor, basic trim, and haul-away. Fiberglass runs $1,060 to $1,770, and wood runs $1,180 to $2,360. If the existing frame is damaged, add $120 to $470 per window for repairs. Call (213) 632-5711 for a free estimate on your specific windows.
How much does window replacement cost for a whole house in Los Angeles?
A full-home window replacement in Los Angeles with 8 to 10 standard vinyl windows typically runs $5,310 to $8,860. The same job with fiberglass or wood windows runs $9,440 to $17,700. Larger homes or historic properties can exceed that range. The only way to know your exact number is a written proposal, which is what we provide every time.
Is it cheaper to repair windows or replace them?
Sealing, weatherstripping, or hardware repair on a window usually costs $100 to $400 per window, compared to $530 to $890 to replace. If the frame is sound and the glass isn’t fogged, repair makes sense. If the seal is broken and you’re getting condensation between the panes, the failure is inside the insulated glass unit, which typically costs almost as much as full replacement to fix correctly. We’ll give you the straight answer on which path costs less over time.
How long does window replacement take in Los Angeles?
For a standard full-home replacement of 8 to 10 windows in Los Angeles, expect 1 to 3 working days, assuming the frames are in good condition and no structural surprises arise. Historic homes or HPOZ projects that require review and approval can extend the total timeline by several weeks before installation even starts. We schedule crews around your availability and can usually start standard jobs within two weeks of contract signing.
Do I need a permit to replace windows in Los Angeles?
If you’re replacing windows with the same size and type, no LADBS permit is usually required. If you’re enlarging openings, adding new windows, or making structural changes, a permit is required and typically costs $150 to $600 for window-related work. If your home is in an HPOZ, you may also need a Certificate of Appropriateness. We handle the permit process for you when it’s required.
