How Much Does New Window Installation Cost in Woodland Hills?

New window installation in Woodland Hills typically costs $450 to $1,850 per window including materials and labor, with most whole-home projects landing between $4,500 and $15,000 depending on window count, frame material, and glass type. A standard 3-by-5-foot double-hung vinyl window runs $450 to $800 installed, while premium fiberglass or wood-clad units with low-E coatings and argon gas fill climb to $1,200 to $1,850 each. In a hillside market like Woodland Hills where many homes sit on sloped lots with stucco exteriors and older aluminum frames from the 1960s and 70s, retrofit installation carries its own labor premium over standard nail-fin new construction.

That’s the honest range. What follows is the full breakdown of where those dollars go, what drives the price up or down in this specific part of the San Fernando Valley, and how to avoid overpaying on a project that should last 20 to 30 years.

Key Takeaways:

• Expect to pay $450 – $1,850 per window installed in Woodland Hills, with $800 – $1,200 as the most common mid-range cost.
• Full-home projects (8 – 12 windows) typically fall between $4,500 and $15,000.
• Vinyl is the value play; fiberglass and wood-clad cost more but hold up better against Valley sun exposure.
• Older Woodland Hills homes built before 1980 often need retrofit windows, which add 15 – 25% to labor costs.
• You’ll want to account for stucco patch work, interior trim, and potential dry-rot repair around old frames.

New Window Installation Cost Breakdown (2026)

Here’s the line-item picture for a typical Woodland Hills home. These numbers reflect what we’ve seen on projects across neighborhoods like Walnut Acres, Carlton Terrace, and the hillside streets south of Ventura Boulevard in 2026.

Line Item	Typical Cost Range (Installed)
Vinyl double-hung window (standard size, retrofit)	$450 – $800 per window
Vinyl double-hung window (standard size, new construction)	$400 – $700 per window
Fiberglass window (low-E, argon filled)	$900 – $1,500 per window
Wood-clad window (Milgard, Marvin, or Andersen)	$1,100 – $1,850 per window
Picture window (large fixed pane, 60+ inches wide)	$800 – $2,400 per window
Sliding glass door replacement (patio, 6-foot)	$1,800 – $4,500 per door
Bay or bow window (3-panel assembly)	$3,500 – $8,000 per assembly
Stucco patch and exterior trim repair (per window)	$75 – $250 per window
Interior trim replacement (per window)	$100 – $325 per window
Dry-rot repair around existing frame	$200 – $900 per window
Full-home install (8 – 12 windows)	$4,500 – $15,000 total
Permits (where required by LA County)	$150 – $500 total

The two big cost drivers are window count and whether the job is retrofit or new construction. Retrofit windows, also called insert or pocket windows, slide into the existing frame without tearing out stucco or interior drywall. They’re faster to install but the frame opening is slightly smaller, and the labor requires careful measurement to avoid gaps. New-construction windows require removing the old frame entirely, flashing to code, and re-patching stucco and trim. That’s a more involved job and a higher labor bill, but it gives you a cleaner seal and a bigger glass area.

In Woodland Hills, many homes in the flatlands south of Burbank Boulevard were built with standard nail-fin windows, so replacement with a similar style is straightforward. The hillside homes north of Ventura Boulevard, particularly in the neighborhoods around Valley Circle Boulevard and Mulholland Drive, often have expansive fixed panes, angled frames, or custom sizes that push labor costs toward the higher end of each range.

What Affects New Window Installation Pricing in Woodland Hills

Window pricing is rarely uniform across a market, and Woodland Hills has a few quirks that you’ll want to factor into a realistic budget.

• Frame material. Vinyl is the most affordable and handles the Valley’s heat fine, but it does expand slightly in direct sun. Fiberglass costs 50 – 80% more and is dimensionally stable in heat, which matters on large picture windows facing south or west. Wood-clad offers the premium look many Woodland Hills mid-century and ranch homes call for, but it costs the most and repels the sun only with regular finish maintenance.
• Glass package. Single-pane windows run cheaper but make zero sense in Woodland Hills, where summer temperatures routinely pass 95°F. Dual-pane with low-E coating is the standard we recommend. Triple-pane adds about 20 – 35% to glass cost and helps most on hillside homes with significant west-facing exposure, where afternoon sun drives cooling bills higher than many homeowners realize.
• Retrofit vs. new construction. If your existing frames are square, dry, and structurally sound, a retrofit keeps costs down. If there’s dry rot around sills or water stains inside the wall cavity, you’re looking at new-construction replacement plus rot repair. Homes built before 1980 in Woodland Hills often have original aluminum frames with little to no flashing, making the upgrade more involved.
• Stucco work and trim. Stucco is the dominant exterior finish in Woodland Hills. Removing an old frame often chips the surrounding stucco, which needs patching and re-texturing to match. Interior trim may also need to be replaced if the new window profile differs from the old one. These are small numbers per window, but they add up quickly on a 10-window job.
• Second-story access. A single-story ranch on a flat lot is fast, ladder-free work. A two-story home or a hillside lot with limited access around the foundation means scaffolding or pump-jack staging, which adds labor time and typically $40 – $80 per window in access costs.
• Permitting and code compliance. The City of Los Angeles requires permits for window replacement when the opening size changes or when egress windows are being added to bedrooms. In most like-for-like replacements, permits are less of an issue, but any structural modifications trigger plan review and inspection fees that range from $150 to $500 for a typical residential job. Our team handles all permitting as part of the written quote. You’ll know the cost before we start.

How to Save on New Window Installation

Saving money on windows is not about finding the cheapest bidder. In our experience, the cheapest bid in Woodland Hills usually means one of three things: a subcontractor who won’t pull permits, a crew that rushes flashing and sealing, or a low-grade glass package that underperforms the moment the first heat wave hits. None of those save you money.

Here’s what actually saves you money.

• Replace in phases, but plan the whole project. If all 12 windows need replacement but your budget covers 5, ask for a full-house plan with a phased install schedule. We write phased projects into the contract at the original pricing, so you’re not paying 2027 prices for the second half of the work.
• Choose the right glass package for each exposure. South- and west-facing windows should carry the better glass. North-facing windows on shaded portions of a lot don’t take the same solar beating. Mixing standard dual-pane on the north side with low-E argon on the south and west sides trims hundreds of dollars off a whole-home project without a noticeable comfort difference.
• Do the prep work on window trim yourself only if you’re confident. Ripping out old interior trim before the crew arrives is simple enough for some homeowners, but be honest about your skill level. If you damage a jamb, you’ve cost yourself more than you saved. Talk to us first and we’ll tell you if your specific window openings are worth prepping.
• Take advantage of manufacturer rebates, not just installer discounts. Milgard, Simonton, and Anlin run seasonal rebate programs that we pass through to our clients. Ask us what’s active when you call. These rebates can trim $40 – $75 per window off the final invoice.
• Get a written price, not a handshake number. The best way to avoid cost creep is to demand a written quote with the line items spelled out. That’s not a favor we do for you. It’s how every Sawyer Remodel project works. The written price is in your hands before any work starts. If the final invoice doesn’t match the quote, you’ve got it in writing to hold us to.

Free estimates are a standing offer. Call us at (341) 217-2776 and we’ll walk every window opening with you, take measurements, and put a firm number in writing. No deposit required for the estimate, no pressure to sign.

New Window Installation vs. Window Replacement: What’s the Difference?

Homeowners often use these terms interchangeably, and most contractors don’t bother to clarify. The difference matters for your budget.

Window replacement generally means swapping an existing window for a new unit in the same opening, same size, roughly the same style. It’s a swap. If your frames are sound and the opening size doesn’t change, this is the faster and less expensive path.

New window installation means cutting a new opening where none existed before, or expanding an existing opening to fit a larger window, or replacing a window with a different style that requires reframing, like converting a pair of double-hungs into a single picture window. This is structural work. It requires heading off the new opening, flashing, drywall patch, stucco patch, and often a permit in the City of Los Angeles.

On a like-for-like swap in a Woodland Hills ranch from the 1970s, replacement costs about 30 – 40% less than cutting a brand-new opening. If you’re adding a window to a dark hallway or expanding a bedroom window to meet egress code for a home addition or remodel, budget for the higher number.

How Much Does Impact Window Installation Cost in Woodland Hills?

Impact windows (also called hurricane-rated or laminated glass windows) run $800 to $2,500 per window installed in Woodland Hills. The range is wide because the glass itself is dramatically more expensive: a laminated impact pane costs 2 to 3 times what a standard dual-pane costs, and the frame must be reinforced to hold it.

Are they worth it in Woodland Hills? For most homes, no. The San Fernando Valley doesn’t get hurricane-force winds, and while Santa Ana wind events can gust to 60 mph, they rarely cause the kind of flying-debris damage that impact glass is tested against. Impact glass does provide a secondary benefit: significant noise reduction. If your home fronts a busy street like Topanga Canyon Boulevard, Burbank Boulevard, or Oxnard Street, the sound-dampening properties of laminated glass are real and measurable. Some homeowners choose impact windows in street-facing rooms purely for the quiet. If that’s you, budget for the higher end of the range and target the noisy exposures only.

For a full breakdown of impact window pricing and how it compares to standard replacement, see our New Window Installation in Woodland Hills guide.

Woodland Hills Window Installation: What We See on Real Projects

We’ve installed and replaced windows across Woodland Hills for the better part of two decades, and certain patterns show up repeatedly.

In Walnut Acres, most homes are single-story ranches built between 1955 and 1975. The original windows are almost always single-pane aluminum sliders with failing seals. Homeowners there tend to choose white vinyl double-hungs as a direct replacement. Typical per-window cost: $500 to $750 installed.

Carlton Terrace and the streets flanking El Camino Real High School feature a mix of 1960s ranch homes and larger two-story builds from the 1980s. The two-story homes often have paired windows or wide picture units over the front entry that cost more per opening due to size and second-story access. Budget $700 to $1,400 per window there.

Hillside homes south of Ventura Boulevard, particularly along roads like Oakdale Avenue and the twisty streets above Mulholland, bring steeper rooflines and larger glass areas. Owners in these neighborhoods often opt for black-frame windows to match modern exterior upgrades, which add 10 – 20% to the frame cost. A black-frame vinyl window in a modern hillside home runs $550 to $950 installed. Black fiberglass starts around $1,100.

One thing we consistently see with 1960s-era Woodland Hills homes: dry rot at the sill corners. The original aluminum windows were rarely flashed properly, and decades of sprinkler overspray against stucco walls wicks moisture into the framing. By the time a window is being replaced, there’s often rot hiding behind the stucco. This is exactly why we schedule a full frame inspection with every estimate. If rot exists, you need to know before the install crew arrives, not when they open the wall and find it.

Window Frame Materials: What Works in the Valley Heat

Woodland Hills sees summer highs that regularly cross 100°F, and certain frame materials handle that heat better than others. Here’s the practical read from years of installs in this climate.

Vinyl is the most common choice and the most affordable. Modern vinyl formulations are far better than the early-2000s product that sagged in heat. A quality vinyl window from Milgard or Simonton holds its shape fine in direct west-facing sun if the frame is properly shimmed and the gap is insulated. Expect 20 – 25 years of service life.

Fiberglass costs more but is the best performer in the Valley. It expands and contracts at a rate almost identical to glass, so seals last longer and the window stays square in extreme heat cycles. For large fixed panes or windows over 60 inches wide, fiberglass is the material we recommend most often. Expect 30+ years.

Aluminum conducts heat, which makes it a poor choice for the frame itself. However, thermally broken aluminum frames (where the inner and outer frame are separated by a non-conductive barrier) have improved significantly. They’re popular on modern hillside homes for their thin sightlines and black finish options. Budget $800 to $1,600 per window.

Wood and wood-clad offer the best appearance for traditional ranch and craftsman-style homes, but they demand maintenance in a dry climate. Wood expands and contracts with humidity changes, and Woodland Hills swings from damp marine-layer mornings to bone-dry afternoons. If you choose wood, plan to reseal exterior surfaces every 3 to 5 years. Budget $1,100 to $1,850 per window and be honest about the upkeep.

Labor Costs for Window Installation in Woodland Hills

Labor makes up roughly 35 – 50% of the total installed price. In the Woodland Hills market as of 2026, window install labor runs $150 to $400 per window for a standard retrofit and $250 to $600 per window for new-construction replacement, with higher numbers on second-story work.

That labor includes removal of the old unit, prep of the opening, setting and leveling the new window, insulating the gap, flashing and sealing, exterior stucco patch, interior trim, and job cleanup. On a 10-window house, a crew of two can usually complete a retrofit in 1 to 2 days. New-construction replacement on the same house takes 2 to 4 days depending on rot repair and stucco drying time.

Our crews are background-checked and uniformed. Every project runs under The Relay Visibility Guarantee, which means you get a live arrival time before we show up, photo updates during the job, and a written price before the first tool is picked up. The guarantee also includes the 365-Day Done Right Promise: if the installation isn’t done right, we make it right, in writing, for a full year after the job closes. That’s not a courtesy. It’s a contract term.

Woodland Hills Window Installation Cost by Home Size

Here’s a practical framework by home size for planning purposes.

• Small condo or townhome (4 – 6 windows): $2,500 to $6,500 total. Condo projects often have HOA rules about window style and color, so check your CC&Rs before selecting anything. We’ll help you match the required look.
• Standard single-story ranch (8 – 10 windows): $4,500 to $9,500 total. This is the most common project size in Walnut Acres and the flatlands north of Ventura Boulevard.
• Two-story home (10 – 14 windows): $6,000 to $14,500 total. Second-story access adds labor, and two-story homes often have larger or paired windows that cost more per unit.
• Large hillside home (14+ windows, mixed styles): $10,000 to $20,000+ total. Custom sizes, big picture windows, slope access, and premium frame materials all push this range higher.

These numbers assume mid-range vinyl or standard fiberglass windows with dual-pane glass. If you’re selecting wood-clad, black frames, or impact glass, add 25 – 50%.

Is New Window Installation Worth It in Woodland Hills?

The short answer: yes, if your current windows are original to a home built before 1990, you’re leaving money on the table every month. Single-pane windows are thermal sieves. In a Woodland Hills summer, rooms facing west become uncomfortable by 4 p.m. regardless of what the thermostat says, and the AC runs longer as a result.

New dual-pane, low-E windows reduce heat gain through the glass by 40 – 60%. On a 2,000-square-foot home, that typically shows up as $25 to $60 per month in summer utility savings, depending on your cooling habits and current window condition. Over 20 years, that’s $6,000 to $14,000 in avoided energy costs. That alone covers a significant portion of the installation price, before you factor in comfort, noise reduction, and not having to struggle with a window that sticks in its track every spring.

FAQs – New Window Installation Cost

How much does window installation cost per window in Woodland Hills?

Window installation in Woodland Hills runs $450 to $1,850 per window installed, with most standard vinyl double-hung units landing between $500 and $800. Premium fiberglass or wood-clad windows cost $1,100 to $1,850 per unit. Call (341) 217-2776 for a free estimate and we’ll put your exact number in writing.

Is it cheaper to repair windows or replace them?

Repairing a window (glass replacement, hardware replacement, weatherstripping) typically costs $100 to $400 per window, so repair is cheaper when the frame is still sound and the opening is square. Replacement becomes the better financial choice when frames are warped, seals are failed, or the window is original single-pane aluminum. Call (341) 217-2776 and we’ll inspect your windows and give you an honest read on repair vs. replace, with numbers for both.

How long does new window installation take?

A standard 8-to-10-window retrofit in Woodland Hills takes 1 to 2 days. New-construction replacement on the same size home takes 2 to 4 days, depending on stucco patching and rot repair. We schedule a firm arrival time, not a four-hour window, and send photo updates during the job.

Do I need a permit to install new windows in Woodland Hills?

Like-for-like replacements that don’t change the opening size typically don’t require a City of Los Angeles permit. Adding a new window opening, enlarging an opening, or installing egress windows in bedrooms requires a permit. Permits run $150 to $500 for typical residential window work. We handle permit research and filing on every project, and the cost is included in your written quote when permits are required.

What’s the difference between retrofit and new-construction windows?

Retrofit windows install into the existing frame without disturbing stucco or drywall, and run 15 – 25% less than new-construction windows. New-construction windows replace the entire frame, which is necessary when there’s dry rot or when you’re changing the opening size. Both have their place. We’ll tell you which is right for each opening in your home and put the line-item cost in your quote.

Can you install windows same-week in Woodland Hills?

We can typically schedule window installation within 1 to 3 weeks of your signed quote, depending on window availability from the manufacturer. Custom sizes or specialty glass can take 3 to 6 weeks. Call (341) 217-2776 to check current lead times for your specific window sizes.
