Impact Window Installation Cost Breakdown (2026)

Impact windows aren’t a single product with a single price. The final number reflects the window itself, the frame material, the labor to remove old units and set new ones, and local permit fees in Woodland Hills. Here’s what we’re seeing across the 91364 and 91367 zip codes in 2026:

Those numbers reflect what Juniper’s team has quoted and installed across Woodland Hills over the past year. The single biggest driver is window size. A standard 36-by-60-inch impact window costs far less than a 72-by-80-inch picture window or a custom-angled unit up in the hills where rooflines follow the terrain. Custom sizing can push per-unit costs 30% to 50% above standard sizes.

Glass package matters too. All impact windows use laminated glass, but the energy-efficiency layer on top of that ranges from basic Low-E coatings to triple-layer argon-filled units. In Woodland Hills, where summer temperatures routinely top 95°F along Topanga Canyon, most homeowners opt for a solid Low-E package, which adds $80 to $180 per window but cuts cooling costs noticeably.

What Affects Impact Window Installation Pricing in Woodland Hills

Woodland Hills has its own pricing dynamics. The mix of housing stock, from 1960s ranch homes south of the Boulevard to newer builds north of Mulholland, plus the local permitting process, all shape what you’ll pay. Here’s what moves the needle:

• Window count and sizes. Most Woodland Hills homes have 12 to 18 windows. If you’re replacing 20-plus, the per-unit cost drops slightly because the crew is already on site. But if you have a 96-inch-wide living room picture window or a wall of glass facing the Valley, expect that single unit to cost $2,000 or more.
• Frame material. Vinyl is the most common choice and the most affordable. Aluminum runs 25% to 35% more and is often required by HOA architectural guidelines for homes in certain neighborhoods south of the Boulevard. Wood-clad is the top end, used mostly on custom or estate properties in the hills.
• Home age and structural condition. In Woodland Hills, many homes date back to the 1960s and 70s. Older openings are less likely to be square and level, which means extra shim work, new flashing, and occasionally rebuilding the rough opening. Homes built before 1978 can also trigger lead-safe work practices, which add $50 to $80 per opening on the labor side.
• Second-story work. If part of your install is on a second floor or requires ladder access on a hillside lot, labor runs higher. Homes along the ridgelines near Topanga State Park often need scaffolding or extended ladder work, adding $40 to $75 per window on those elevations.
• HOA requirements. A significant portion of Woodland Hills sits within HOAs that dictate window style, frame color, and even specific product approvals. If your HOA requires a specific brand like PGT WinGuard or CGI, that narrows choices and can affect pricing. Check your CC&Rs before choosing a product.
• Time of year. Demand for window replacement dips slightly in January and February, while late spring and early fall are peak booking periods. Off-season work sometimes means faster scheduling, though published pricing at Juniper stays consistent year-round rather than swinging with seasonality.

Impact Window Costs by Window Type in Woodland Hills

Not every window in your house is the same style, and that’s reflected in pricing. Here’s a working set of ranges for the styles homeowners in Woodland Hills are most likely to have:

• Single-hung impact windows: $620 to $1,150 per unit. The most common style in older Woodland Hills homes. Bottom sash moves, top stays fixed. Straightforward to install.
• Horizontal sliders: $700 to $1,400 per unit. Extremely popular in mid-century ranch homes. Wider units cost more per square foot because the glass package gets heavier.
• Casement windows: $850 to $1,600 per unit. Crank-operated, often used in kitchens and bathrooms. The hardware adds cost, and these require precise installation to seal properly against wind-driven rain.
• Picture windows (fixed): $950 to $2,600 per unit depending on size. These don’t open, which means no operable hardware, but the glass can be laminated at larger dimensions, and that pushes cost quickly.
• Awning windows: $680 to $1,250 per unit. Smaller, hinge at the top. Common in bathrooms and above kitchen sinks.

How Impact Window Pricing Compares to Standard Window Installation in Woodland Hills

You’ll pay 35% to 60% more for impact-rated windows than for standard energy-efficient windows of the same size and frame material. A standard vinyl window runs $350 to $700 per unit. The impact-rated version of the same size runs $550 to $1,200. The price difference comes from the laminated glass layer, which adds weight and material cost, plus the heavier-duty frame construction required to hold that glass under pressure.

Is it worth it? For most Woodland Hills homeowners, the math works like this: impact windows provide year-round protection against intruders, reduce outdoor noise from Ventura Boulevard and the 101, and eliminate the need to install or unpack storm shutters before fire season or a wind event. They also often qualify for homeowners insurance discounts, particularly on properties in hillside zones where wind and brush exposure drive premiums higher.

How to Save on Impact Window Installation

You don’t need to compromise on product quality to keep the number reasonable. What you need is an accurate scope and a contractor who prices in writing. Here’s what actually moves the dial in Woodland Hills:

• Replace all windows at once. Mobilization costs get spread across more units. A 15-window project typically lands 8% to 12% lower per window than doing five windows at a time.
• Stick with standard sizes. Custom sizing is one of the fastest ways to inflate a quote. If a window does not need to be resized, don’t resize it.
• Choose vinyl frames unless your HOA says otherwise. Vinyl impact windows now come in colors that satisfy most architectural review boards, and they deliver solid energy performance at the lowest price point.
• Check with your insurance agent before you buy. Many carriers in California offer discounts of 5% to 15% for homes with impact-rated openings. That doesn’t change the install price, but it changes the long-term cost picture.
• Get a written quote and compare line items. At Juniper, we price everything in writing up front, so you can see exactly what is included before you commit. Call (831) 508-3441 for a free estimate, and we’ll walk you through equipment options, opening counts, and an itemized number.

Does Impact Window Installation Require a Permit in Woodland Hills?

Yes. Window replacement in Los Angeles, including Woodland Hills, requires a building permit when openings are being altered or when you’re upgrading to impact-rated units, which changes the structural load characteristics of the wall. The permit process runs through the Los Angeles Department of Building and Safety, and fees typically land between $200 and $600 for a whole-home window replacement.

Juniper handles the permit application and inspection coordination as part of the project scope. You won’t be asked to pull a permit yourself or track down an inspector. The inspection itself is typically scheduled after all windows are in, and the inspector verifies that the installation matches the approved plans and that the impact-rated labels are visible on each unit.

FAQs – Impact Window Installation Cost

Here are the questions homeowners in Woodland Hills ask us most often when pricing impact windows. Every answer leads with a number so you get the figure up front.

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

Plan on $900 to $2,400 per window installed for most mid-range impact windows in Woodland Hills. That figure includes the window unit, labor, flashing, and disposal of the old window. Premium products like wood-clad impact windows, or custom sizes, can push past $3,000 per opening. Call (831) 508-3441 and we’ll price your specific window list in writing, free.

Is it cheaper to repair or replace an impact window?

If the frame is intact and only the seal or glass needs work, repair runs $250 to $600 for glass replacement on a standard size. But if the frame is warped, the window is over 15 years old, or the impact rating is outdated, replacement at $900 to $2,400 per window is usually the better long-term call. Juniper’s 365-Day Done Right Promise covers new installations for a full year, parts and labor, in writing.

How much does it cost to install impact windows in a 2,000-square-foot home in Woodland Hills?

For a typical 2,000-square-foot home with 13 to 16 windows, you’re looking at $14,000 to $24,000 for mid-range impact windows. Homes with larger openings, second-story glass, or aluminum frame requirements land on the higher end of that range. Juniper gives every customer a written price before any work starts, so there’s no guessing and no change order surprise.

Do impact windows actually lower insurance premiums in California?

Yes, in many cases. California insurance carriers often apply a wind-mitigation discount when impact-rated windows are installed, typically 5% to 15% off the wind portion of the premium. The amount depends on your carrier and your specific hillside or brush-zone rating. The bigger long-term savings is often avoiding the cost and hassle of installing and maintaining storm shutters when a wind event is forecast.

How long does impact window installation take in Woodland Hills?

Most whole-home impact window installations in Woodland Hills take 2 to 4 days, depending on window count and home access. A single opening can often be replaced in under two hours. Juniper schedules a live arrival time you can track, sends photo updates during the job, and will have your new windows operational before the team leaves the site.

Can you install impact windows same-day in Woodland Hills?

For most projects, no. Impact windows are usually custom-ordered from PGT, CGI, or one of our other product lines, which means 2 to 6 weeks from order to install. However, Juniper does stock some standard sizes for immediate replacement needs, and we’ll always tell you honestly whether your project can be fast-tracked. Call (831) 508-3441 and we’ll check availability for your window sizes.

Why Homeowners in Woodland Hills Choose Juniper Windows & Doors

Juniper Windows Woodland Hills is part of the Relay Home Co. family, founded in 2001 with more than two decades of installations behind the brand.

We carry eight product lines, including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That range matters because Woodland Hills is not a one-size-fits-all market. A 1961 ranch south of the Boulevard has different window needs than a gated estate above Mulholland, and you shouldn’t be forced into whichever product one contractor happens to carry.

The Relay Standard is how we run every job: book in a tap, get a live arrival time you can track, see before-and-after photos of the work, and pay from a digital invoice link. Calls are answered by a live person 24/7. The name Juniper comes from the hardy evergreen, built to handle sun, wind, and cold.
