Patio Door Installation Cost - Written Price Before Anything Is Ordered

How Much Does Patio Door Installation Cost in Woodland Hills?

Patio door installation in Woodland Hills typically runs between $2,700 and $7,400 for a complete project in 2026, with most homeowners paying around $4,800 for a mid-range sliding glass door, including labor, the door itself, and basic finish work. Entry-level sliders start near $2,200 when the opening is already framed and no structural work is needed. French patio doors and impact-rated models push the top end past $9,000, especially in hillside neighborhoods where permits and wind-load requirements add cost.

Those are real numbers for the Woodland Hills market, not national averages. The spread comes down to door type, glass package, whether the existing frame is salvageable, and the specifics of your home’s construction. Below we break down exactly where the money goes, what drives quotes up or down, and what you should expect from a contractor who gives you a written price before any work starts.

Patio Door Installation Cost Breakdown (2026)

Here’s a line-by-line look at what a patio door project costs in Woodland Hills this year. These ranges reflect quotes we see on single-family homes across neighborhoods like Walnut Acres, Vista de Oro, and the flats south of Ventura Boulevard.

The single biggest variable is the door itself. A builder-grade vinyl slider from a big-box store lands at the bottom of the range. A Therma-Tru fiberglass French door with low-E glass and a multi-point lock lands at the top. The second biggest variable is what’s behind the old door. Woodland Hills homes built in the 1960s and 70s often hide rotted framing or termite damage around the door opening, and that discovery changes the quote. This is exactly why Juniper writes a firm price before the first screw turns: the number already accounts for what we expect, and if we find something the former homeowner patched over, you’ll know before you owe, not after.

What Affects Patio Door Installation Pricing in Woodland Hills

• Door material and glass package. Vinyl is cheapest. Fiberglass runs 20-40% more. Low-E glass adds $300-$600 per door. Impact-rated glass, the kind you see on newer canyon homes near Topanga, effectively doubles the glass cost because it’s built to resist wind-borne debris without shattering.
• Door width and configuration. Standard 6-foot sliders are the budget option. Eight-foot and multi-panel doors, common in Woodland Hills ranch homes that open onto a pool deck, cost 30-60% more because the panels are heavier and the track system is more complex.
• Existing opening condition. Same-size replacement is cheapest. Widening an opening means header work, stucco repair, and drywall matching. On homes along Dumetz Road and in the hills above the 101, older sections often have non-standard rough openings that require custom sizing.
• Permits and local code. Woodland Hills falls under L.A. city jurisdiction, so any door that changes the opening size needs a permit. Hillside and wildfire-adjacent parcels also carry glazing and wind-load requirements that can add $400-$900 to a project. A contractor who skips the permit is cutting your resale value, not doing you a favor.
• Stucco and exterior finish. Most Woodland Hills homes have stucco exteriors. Pulling an old patio door damages the stucco around the frame, and matching decades-old texture takes a skilled hand. Exterior finish work adds $250-$1,400 depending on the width of the damage band.
• Time of year. Patio door work in Woodland Hills slows slightly from Thanksgiving through January, though the weather here rarely stops outdoor work. Booking in late winter can sometimes shave 5-10% off labor because crews have lighter schedules.

How Much Do Different Types of Patio Doors Cost in Woodland Hills?

Here’s the honest breakdown by door type, using 2026 pricing for this specific market:

Sliding Patio Doors: $2,200 to $6,500 Installed

A standard two-panel slider remains the most common choice in Woodland Hills, especially for single-story homes where the door opens to a patio or pool. Vinyl sliders with basic glass start around $2,200 installed. Stepping up to low-E glass, a better track, and taller panels pushes the number to $3,500-$4,800. Premium sliders from PGT or ES Windows with thin sightlines and impact-rated glass land between $5,500 and $6,500. Sliding doors suit homeowners who want the widest possible glass area without swinging door panels eating up patio space.

French Patio Doors: $3,500 to $8,500 Installed

French doors, two hinged panels that swing open from the center, remain popular on Woodland Hills homes with visible front patios or dining rooms that open to a garden. Expect $3,500-$5,000 for a standard fiberglass or wood French door with double-pane glass. Therma-Tru models with composite frames, internal blinds, and multi-point locking run $6,000-$8,500. French doors offer a wider clear opening than sliders, which matters when moving furniture or hosting larger groups through the patio.

Impact-Rated Patio Doors: $5,000 to $11,000+ Installed

Impact-rated glass is built to resist wind-borne debris without shattering, the same standard used in Florida’s hurricane zones. In Woodland Hills, impact-rated doors typically appear on canyon-adjacent homes in the hills near Topanga State Park, where wind gusts and wildfire embers are a real concern. Entry-level impact sliders from CGI or CWS start near $5,000 installed. Large multi-panel impact doors easily exceed $11,000. The glass is heavy, the frames are reinforced, and installation takes a full day or more with a two-person crew.

Multi-Slide and Bi-Fold Patio Doors: $8,000 to $18,000+

Multi-slide doors, where three or more panels stack against each other to open most of a wall, run $8,000-$14,000 depending on width and glass. Bi-fold doors with panels that concertina to the side are the premium option, often $12,000-$18,000 or more once you factor in structural support and the larger opening these doors demand. We see these most on Woodland Hills remodels where a kitchen or family room wall is being opened to a backyard

Is Patio Door Replacement Cheaper Than Installation?

Yes, and the distinction matters. If you’re swapping an existing patio door for a new one in the same rough opening, you’re doing a replacement and the cost sits at the lower end of the table above. If you’re cutting a new opening, moving a door, or widening an existing one, that’s new installation and it adds $1,500-$5,000 for framing, header work, drywall, stucco, and permits. In Woodland Hills, most projects are replacements, because the original patio door usually sits in a logical location already. Before you plan around moving a door, have a contractor look at the wall section: a simple replacement can save thousands.

Labor Costs for Patio Door Installation in Woodland Hills

Labor alone for a standard patio door replacement runs $700-$1,200. That covers removing the old door, disposing of it, setting and leveling the new door, securing it, trimming the interior, and caulking the exterior. On higher-end installations, labor climbs to $1,500-$1,900 because impact-rated doors and custom French doors take longer to set, square, and seal. Two-person crews are standard for anything with heavy glass.

What you’re paying for in labor: a square installation, a track that doesn’t bind, weatherstripping that actually seals, and a door that slides or swings without effort. A rushed one-person install is the most common source of patio doors that leak air, drag on the track, or develop condensation between panes within two years. Background-checked, uniformed technicians handle every Juniper job, and each installation carries a 365-Day Done Right Promise in writing: if the work isn’t right, it’s fixed for a full year, parts and labor included.

How to Save on Patio Door Installation

• Keep the same size. A same-size replacement eliminates framing, stucco, and permit costs. This is the single biggest money-saver, often $1,000-$3,000.
• Choose vinyl over wood or fiberglass. Vinyl sliders are $1,000-$2,500 cheaper than comparable French or fiberglass doors, and modern vinyl holds up well against Woodland Hills sun and heat.
• Book in the off-season. Late winter (January through early March) is the slowest stretch for door installers in the L.A. area. Scheduling then can shave labor costs 5-10%.
• Replace both doors at once, if you have two. Homes with a side patio door and a rear patio door save $300-$600 on setup and trip fees by batching them into one job.
• Ask for a written, itemized price. A contractor who won’t put the number on paper before starting is testing whether you’ll absorb surprise charges. Juniper gives every job a written price beforehand, so there’s no pressure to accept a number that shifts at the door.

Why Patio Door Costs Vary Between Contractors in Woodland Hills

Two contractors can quote the same patio door $1,500 apart because they’re not actually quoting the same job. One includes haul-away, stucco patch, flashing, and finish trim. The other leaves those line items off the estimate and adds them after the old door is out. One quotes a bare-bones vinyl slider with single-pane glass. The other quotes low-E glass, a steel-reinforced frame, and upgraded hardware. When you compare quotes, compare line items, not just the bottom number.

And then there’s the product line. Juniper carries PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux: eight product lines, from practical vinyl sliders to impact-rated doors built to take a hit. A contractor with one product line has one answer for every home. That’s not how door selection works in a place where some houses face full afternoon sun and others sit in a wind corridor above the valley floor.

Woodland Hills Specifics: Permits, Stucco, and Older Homes

Woodland Hills sits within Los Angeles city limits, so door work is governed by L.A. municipal code. A same-size replacement where the opening isn’t being modified typically doesn’t need a permit, though the code inspector cares about the final condition of the exterior and any exposed flashing. A new opening, a widened opening, or a header change requires a building permit. Permit fees for door work run $150-$650 depending on the project’s valuation.

Stucco is the other local factor. Most homes in Woodland Hills, particularly the ranch-style and mid-century stock between Topanga Canyon Boulevard and Shoup Avenue, were built with stucco exteriors. Every patio door replacement means at least some stucco repair around the new frame, and matching 50-year-old stucco texture is an art. The right contractor sends someone who can blend it so the patch doesn’t shout. The wrong contractor sends whoever is free, and you’ll see the outline forever.

Older homes also hide surprises. In neighborhoods like Woodland Hills Estates, where houses date to the 1950s and 60s, the rough opening around a patio door may be framed with old-growth lumber that’s warped or riddled with termite tunnels. This is normal for the age, but it changes the install, and a contractor who quotes blind is a contractor who will come back asking for more. A proper quote involves pulling the interior trim during the estimate to look at the framing before a number is promised.

Patio Door Installation Timeline: How Long Does It Take?

A standard patio door replacement takes one day, typically 4-6 hours for removal, setting, trim, and cleanup. Same-size French door installations run 5-7 hours because there are two swinging panels to level and align. Impact-rated and multi-slide doors can take a full day or a day and a half, given the weight and the added flashing requirements. If the opening needs reframing or stucco work, add a half day or a full day. Most Woodland Hills jobs are done in a single day, with stucco touch-up scheduled as a short follow-up visit.

Juniper schedules the finish work while the door is going in, so you’re not left waiting on a stucco crew for two weeks. And every project gets the Relay Visibility Guarantee: a live arrival time you can track, before-and-after photos of the job, a written price, and a digital invoice you can pay from a link. That’s the same standard you’d expect from a rideshare app, applied to a patio door.

FAQs – Patio Door Installation Cost

How much does a patio door cost in Woodland Hills?

A basic sliding patio door installed in Woodland Hills costs $2,200 to $3,800. Mid-range sliders with low-E glass run $3,500 to $5,000. French doors start around $3,500 and climb to $8,500. These figures include labor, the door, haul-away, and basic finish work. Call (831) 508-3441 for an exact written quote on your specific opening.

How much does it cost to install a patio door where there is no door?

Cutting a new patio door opening in Woodland Hills costs $2,000 to $5,500 in added structural work: framing the opening, installing a header, patching drywall and stucco, and pulling a permit. That’s on top of the door itself and standard labor. New openings make the most sense when a kitchen or family room has no other path to the backyard.

How much does Home Depot charge to install a patio door?

Big-box patio door installation runs $900 to $1,800 for labor alone in the Woodland Hills area, depending on door type and opening condition. That’s typically contracted out to a third-party installer. Juniper’s pricing is comparable on labor, but the difference is that installation is done by background-checked, uniformed Juniper technicians, and every job carries the 365-Day Done Right Promise in writing.

Is it cheaper to repair a patio door than replace it?

Yes, until it isn’t. Replacing a roller or adjusting a track costs $150 to $350 in Woodland Hills. Resealing or replacing weatherstripping runs $100 to $250. But if the frame is rotted, the glass is fogged between panes, or the door drags because the frame itself is out of square, repairs become a treadmill. A 20-year-old door with a failing seal is usually better replaced. We’ll tell you plainly which side of that line your door falls on when you call.

Can you install a patio door the same day?

Usually not the same day, because the door itself has to be pulled from inventory or ordered to your opening size, and many Woodland Hills homes have non-standard rough openings that require custom sizing. Standard-size replacements can typically be installed within a week of measure. Once installation day arrives, the job itself is done in one day for most sliders and French doors. Call (831) 508-3441 for a free estimate and we’ll give you a real timeline along with the price.
