How Much Does Patio Door Installation Cost in Woodland Hills?

Patio door installation in Woodland Hills typically runs between $1,800 and $6,500 for most standard projects in 2026, with the average homeowner spending around $3,400. Sliding glass patio doors land on the lower end of that range, while French doors, multi-slide doors, and projects requiring structural header work push toward the top. The final number depends on door type, glass package, framing condition, and whether you’re replacing an existing door or cutting a new opening.

At Sawyer Remodel Woodland Hills, we put the price in writing before any work starts, so the number you approve is the number you pay. Call (341) 217-2776 for a free estimate on your specific door and opening.

Patio Door Installation Cost Breakdown (2026)

Here’s a line-item breakdown of what we see across Woodland Hills, Warner Center, and the neighborhoods south of Ventura Boulevard. These are real numbers from real projects we’ve priced in the last 18 months, not national averages.

Cost Component	Typical Range	Notes
Sliding patio door (standard vinyl frame, 72″ x 80″)	$800 – $2,000	Material cost only; brands like Milgard, Andersen, and Jeld-Wen fall here.
French patio door (two-panel, fiberglass or wood-clad)	$1,600 – $4,200	Cost varies with material. Wood-clad from Andersen or Marvin lands higher.
Multi-slide or folding patio door	$5,000 – $14,000+	For wide openings. Often a 4-panel or larger system. Yes, this exceeds the $6,500 “typical” ceiling for standard projects – these are specialty.
Labor for direct replacement (same size, same opening)	$600 – $1,400	Removal, framing inspection, install, flashing, trim, and haul-away.
Labor for new opening or widening existing opening	$1,500 – $3,500	Includes header work, structural support, drywall patching, and exterior siding/stucco repair.
Permits (City of Los Angeles / Woodland Hills jurisdiction)	$150 – $400	Required for structural changes; direct replacements often skip this.
Disposal and haul-away of old door	$75 – $250	Usually bundled into labor if you hire a full-service contractor.
Stucco or siding repair around new frame	$200 – $900	Needed when the new door footprint doesn’t match the old one exactly.
Interior trim and casing	$150 – $600	New trim cuts, paint-ready or pre-finished.

Two years ago, a standard sliding door replacement in Woodland Hills often came in under $1,600. That’s changed. Material costs for glass packages and aluminum frames have climbed steadily since 2024, and local demand for energy-efficient upgrades (Title 24 compliance on replacement windows and doors) has pushed labor rates higher across the San Fernando Valley. We’re now seeing $2,800 to $3,600 as the most common quoted range for a quality slider installed by a licensed contractor who pulls permits when required.

One more thing that matters: the condition of your existing rough opening. Houses in the original 1950s and 60s tracts south of the Boulevard often have single-pane aluminum sliders in openings that are no longer square. Framing correction adds labor hours you won’t see in a national cost guide.

What Affects Patio Door Installation Pricing in Woodland Hills

Woodland Hills has its own cost drivers, and they’re not the same as what you’d see in Santa Monica or Thousand Oaks. Here’s what actually moves the number:

• Door type and glass package. A basic vinyl slider with dual-pane clear glass costs half of a wood-clad French door with Low-E tinted glass. In our market, homeowners overlooking the Santa Monica Mountains often choose Low-E coatings specifically for afternoon heat gain from the west-facing exposure. That glass package adds $300 to $800 per door, and it’s worth every dollar in August.
• Whether the opening is existing or brand new. Replacing a slider in an existing opening is a one-day job. Cutting a new opening in a stucco exterior wall means framing a new header, possibly adding shear wall reinforcement, patching stucco, and re-trimming both sides. That’s a completely different project with a different price.
• Stucco repair scope. Most Woodland Hills homes built before 1990 have wood-framed walls with traditional three-coat stucco. When you resize an opening, the stucco patch needs a proper weep screed and curing time. Shoddy contractors skip this step and the stucco cracks within a year. We budget for it up front.
• Title 24 energy compliance. California’s energy code requires replacement patio doors to meet minimum U-factor and Solar Heat Gain Coefficient ratings. That means the cheap door from a big-box store might not pass inspection if you’re pulling a permit. Compliant doors cost more, but they’re the only ones we’ll install – it’s not worth failing an inspection over a $200 savings.
• Access and site conditions. If your patio door faces a hillside or a retaining wall within a few feet, the crew’s staging options get tight. We’ve done installs on Woodland Hills hillside homes where the old door had to come out through the house and the new one had to come up a slope with a material lift. It adds time, and time is labor.
• Door size. Standard patio doors are 6 feet wide. An 8-foot or wider opening typically uses a larger unit or a multi-panel setup, and the price jumps accordingly. Homes in the Calabasas-adjacent pockets of Woodland Hills with 9-foot ceilings often have taller doors that are special-order items.

Patio Door Types and Their Installed Costs in Woodland Hills

Sliding Glass Patio Doors: $1,800 – $4,200

The workhorse. Two or three panels, one fixed, one or two that slide. Vinyl frames dominate this segment in Woodland Hills because they handle the dry heat without warping. If you’re replacing an existing slider and the opening is in good shape, this is the most cost-effective route. Expect one day of work and minimal disruption.

French Patio Doors: $2,800 – $6,500

Two hinged panels that swing inward or outward. The price range is wider because material options vary so much: a fiberglass French door from Milgard starts lower, while a wood-clad unit from Andersen or a fiberglass-composite from Marvin sits at the top. French doors also require more precise installation – the hinge side has to be shimmed perfectly or the doors sag over time. In Woodland Hills, where afternoon sun heats the west side of the house hard, we recommend fiberglass over solid wood for anything that faces south or west.

Multi-Slide and Folding Patio Doors: $6,000 – $14,000+

These are the doors you see in the modern post-and-beam homes in the hills above Mulholland. A 12-foot opening fully opens to the patio with panels that stack or fold. The hardware alone runs $2,000 to $5,000 for quality systems like LaCantina or Western Window Systems. This is a premium category, and anyone quoting you $4,000 for a folding door is quoting hardware only, not installed.

Bifold Patio Doors: $4,500 – $11,000

Similar to folding doors but with narrower panels and a slightly lower hardware cost. Popular in the newer communities off Valley Circle and in the condos along Topanga Canyon. Installation complexity is high, and the floor track needs to be perfectly level – something that isn’t always a given in older homes with settled slabs.

Labor Rates for Patio Door Installation in Woodland Hills

General contractors and door specialists in the Woodland Hills area charge between $85 and $150 per hour for patio door installation work. A straightforward slider replacement is a four-to-six hour job for a two-person crew, which is why labor lands between $600 and $1,400. A new opening with framing, stucco patching, and trim work can take two to three days, putting labor between $1,500 and $3,500.

We don’t bill hourly on most patio door projects. We quote a flat price, in writing, after measuring your opening and specifying the exact door. That way the number doesn’t creep on you mid-project. If the scope changes because we find something behind the wall – termite damage, improper framing from a past remodel – we stop, show you photos, and give you a revised price before touching it.

Can You Install a Patio Door Yourself?

We’re going to be direct about this: a patio door replacement is not a weekend DIY project for most people. The door unit weighs anywhere from 150 to 400 pounds depending on the panel count and glass package. If it’s a new opening, you’re cutting into a load-bearing exterior wall, which means temporary shoring, header sizing, and shear wall requirements that have to be engineered and inspected. A mistake on a load-bearing wall in a Woodland Hills home is not a cosmetic problem. It’s a structural one that can cost $10,000-plus to fix and may void your homeowner’s insurance if it wasn’t permitted.

Even a same-size replacement has failure points: flashing, waterproofing the sill pan, and shimming the frame so the rollers don’t wear out in six months. We’ve fixed enough DIY slider installs to know where the corners get cut.

If you’re on a tight budget, there are ways to reduce cost without doing the dangerous part yourself. More on that below.

How to Save on Patio Door Installation

Saving money on a patio door doesn’t mean buying the cheapest door at the home center. It means avoiding waste, rework, and surprise charges. Here’s how Woodland Hills homeowners cut their costs without cutting corners:

• Replace before the opening rots. If water has been getting past the old door for years, the subfloor and bottom plate may need repair. The earlier you catch it, the smaller the repair. We’ve seen homeowners wait until the drywall is soft and the floor bounces, then the project doubles in scope.
• Choose a standard size off the shelf. A 72″ x 80″ slider is stocked by most manufacturers. Once you get into 96″ widths or 84″ heights, you’re paying for a special-order unit with a four-to-six week lead time and a markup.
• Keep the same door type. Slider-to-slider replacement is the cheapest install. Switching from a slider to a French door usually requires resizing the rough opening, adding framing, and possibly new stucco work. It’s a bigger project than it looks.
• Do the demo prep yourself. If you’re replacing a slider and you’re comfortable removing the interior trim and clearing the area around the door, that saves a crew an hour or two. Just don’t remove the door itself – it’s heavy and awkward, and that’s what the pros are for.
• Bundle it with other work. If you’re already replacing windows or doing a home remodel, adding a patio door to that scope is cheaper than doing it as a standalone project. The contractor is already on site, permits are already pulled, and the crew doesn’t have to remobilize.
• Get three written quotes, but compare line items, not just totals. A $2,900 quote that includes flashing, permit, haul-away, and a one-year install warranty beats a $2,500 quote that adds those as “extras” later. We give a written price before any work starts, and that price includes everything we discussed during the walkthrough.

Permits and Building Codes for Patio Door Installation in Woodland Hills

Woodland Hills falls under the City of Los Angeles building jurisdiction. Here’s the short version of what you need to know:

If you’re replacing a patio door in the same rough opening with a door of the same or smaller size, you generally don’t need a permit. The California Building Code treats this as a like-for-like replacement. If you’re cutting a new opening, widening the existing one, or relocating a door, you need a permit. That requirement is not optional, and unpermitted structural work on an exterior wall is exactly the kind of thing that bites homeowners when they sell.

LADBS permit fees for a door opening change run roughly $150 to $400 depending on the scope. The inspection process adds about a week to the project timeline when you factor in the rough framing inspection before the drywall and stucco go back up.

We handle permits as part of the project. You don’t go to the LADBS counter, you don’t chase inspectors, and you get photos of the completed work for your records.

Energy Efficiency and Title 24 Requirements

California’s Title 24 energy standard applies to replacement patio doors. In simple terms, the door you buy has to meet a minimum U-factor (how well it insulates) and a maximum Solar Heat Gain Coefficient (how much heat it lets through from the sun).

For Woodland Hills specifically, the climate zone designation requires a door that handles the Valley’s hot, dry summers. The west-facing patio doors in our area get hammered by afternoon heat from June through October. A door with a Low-E coating and a thermally broken frame will noticeably reduce your cooling load. It costs more up front – typically $300 to $800 more than a non-compliant or basic unit – but it’s code-compliant, it qualifies for any available utility rebates, and it keeps the room on the other side of that door livable in August.

How Long Does Patio Door Installation Take in Woodland Hills?

For a same-size slider or French door replacement, plan on one day. The crew arrives in the morning with the new door, removes the old one, inspects the opening for rot or framing issues, sets the new unit, flashes it correctly, and trims the interior by the end of the day. Cleanup included.

For a new opening or an opening that needs to be widened, expect two to three days plus time for inspections and stucco curing. The sequence is: cut and frame the opening, set the door, pass rough inspection, then patch stucco and drywall, then trim and paint. The stucco patch needs time before it can be painted, so the crew may return for a short visit a week later.

Why We Price Patio Doors the Way We Do

Sawyer Remodel Woodland Hills is run by Luca Romano, and every patio door project follows The Relay Standard. That means three things happen on every single job:

1. A written price before any work starts. You get a line-item quote after we measure the opening and spec the door. No allowances, no “we’ll see what we find” language. The number on the invoice is the number you approved.
2. Live arrival time and photo updates. You know who is coming before they arrive – background-checked, uniformed technicians – and you get before-and-after photos of the work, including the things you can’t easily see, like the flashing under the sill.
3. A 365-Day Done Right Promise. If the door installation isn’t done right within the first year, we make it right. That’s in writing on every patio door project, not a verbal handshake.

Our material partners for doors and windows include manufacturers with real factory warranties behind the product. We don’t install off-brand imports that can’t be serviced when a roller fails or a glass seal breaks two years in. That matters in Woodland Hills, where the dry heat and strong sun test every component a door has.

FAQs – Patio Door Installation Cost in Woodland Hills

How much does it cost to install a sliding glass patio door in Woodland Hills?

A sliding glass patio door installed in Woodland Hills typically costs $1,800 to $4,200 in 2026. A direct replacement in an existing opening with a standard 72″ x 80″ vinyl slider lands around $1,800 to $2,800, while a larger unit with upgraded glass and a thermally broken frame runs $3,000 to $4,200. Call (341) 217-2776 for an exact quote on your opening – estimates are free.

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

If the door frame and glass are in good condition, repairing a roller, track, or handle typically costs $150 to $500 in Woodland Hills. But if the frame is warped, the glass is fogging (failed seal), or the door is original to a 1960s or 70s house with no thermal break, replacement is the better investment. A repair on a door that should be replaced just pushes the real cost down the road, and you’ll pay labor twice.

How much does it cost to convert a window into a patio door?

Converting a window to a patio door in Woodland Hills costs $4,000 to $9,000 for a standard 6-foot opening. The range includes cutting the exterior wall, installing a proper header, framing the opening, stucco patching, drywall, trim, and the door itself. Permits add $150 to $400. It’s a two-to-three day project plus inspection time.

Can patio doors be installed in one day?

Yes, a same-size patio door replacement is a one-day installation in most Woodland Hills homes. The crew removes the old door, inspects the opening, sets the new unit, flashes it correctly, and finishes interior trim by end of day. New openings or enlargements take two to three days plus inspection and stucco curing time.

Do I need a permit to replace a patio door in Woodland Hills?

For a like-for-like replacement in the same rough opening, no permit is required under City of Los Angeles building code. For a new opening, a widened opening, or any structural change to an exterior wall, yes – a permit is required and the work must pass inspection. We can confirm which applies to your project during the free estimate.

How much does a multi-slide patio door cost installed?

A multi-slide or folding patio door system installed in Woodland Hills runs $6,000 to $14,000+ depending on width, panel count, and hardware grade. Quality hardware from manufacturers like LaCantina or Western Window Systems accounts for a significant portion of that cost. These are specialty installations that require exact level floor tracks and precise engineering.
