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 costs between $2,800 and $6,500 for a mid-range sliding door, including the door, labor, haul-away, and basic finish work. Higher-end French doors or multi-slide systems from PGT or Therma-Tru run $7,000 to $14,000. Most homeowners in the area pay around $4,200 for a standard 6-foot sliding patio door with a written quote before work begins.

Patio Door Installation Cost Breakdown (2026)

Here’s what we see across Woodland Hills, from the 101 corridor up through the hills south of Ventura Boulevard. Prices assume a standard opening with no structural surprises hiding in the wall. Older homes in Woodland Hills, especially the late-1960s ranch styles built into the hillside, sometimes need header reinforcement, which adds cost.

The final number moves with a few things: whether you are swapping a like-for-like door or enlarging the opening, what glass package you choose (single-glazed is rare now, but it is cheaper), and which neighborhood you are in. Homes off Mulholland Drive with tight stair access cost more to get a crane or extra crew up the hill than a flat lot near Warner Center.

What Affects Patio Door Installation Pricing in Woodland Hills

• Door type and size. A basic 5-foot vinyl slider costs less than half of a 12-foot multi-slide. The bigger the glass, the bigger the price tag. French doors always cost more than sliders because they need two weather-sealed swinging units and more precise hinge alignment.
• Glass package. Low-E glass (a thin coating that blocks heat while letting light through) adds $200 to $600 depending on the brand. Impact-rated glass, which matters for wildfire and wind zones on hillside properties, can add $1,500 to $3,500 to a large door. We install PGT and CGI impact products regularly in Woodland Hills because many canyon-adjacent lots sit in designated high-wind or brush zones.
• The condition of the existing opening. Dry rot around the threshold is common here because the microclimate near the Santa Monica Mountains means fog and morning damp on the south side, and old single-pane frames were never properly flashed. If the subfloor or studs need replacing, budget $400 to $1,200 in repair before the new door goes in.
• Stucco remediation. Most Woodland Hills homes are stucco. Cutting a larger door opening means stucco control joints, paper, and color-matching. That is $300 to $800 on a typical job, more if the stucco is a custom tint that has to be mixed on site.
• Access and elevation. Hillside lots south of Ventura Boulevard often require walk-up carries or material lifts. Driveway length, stair count, and whether the door can come in through the back all affect labor. A second-floor install off the primary suite adds $200 to $500 for ladder work and careful glazing handling.
• Permit status. A straight swap of the same size door rarely needs a permit. Enlarging the opening, cutting into a shear wall, or changing the header triggers a Los Angeles County Building and Safety review, and that adds time and $150 to $500 in fees. We handle the paperwork when it is needed.

Spencer Odell, who leads Hale Windows & Doors in Woodland Hills, puts it this way: “The price should never be a mystery. You should know your number before a crew shows up.” That is why every quote we give is a written price delivered before any work starts.

How to Save on Patio Door Installation

• Replace like-for-like. Keeping the same rough opening size is the single biggest money saver. No new header, no stucco patch beyond the frame area, no permit. If your existing 6-foot slider works for your layout, do not let anyone talk you into widening it for a bigger view unless you want to pay for the structural work.
• Schedule during the slower season. Window and door crews in Woodland Hills book hardest from March through August. A late-fall or winter install, when the workload is lighter, sometimes gets you a modest labor break. We quote every job the same way regardless of season, but the scheduling flexibility helps.
• Choose vinyl over wood. Vinyl doors run $900 to $1,800 for the door itself, versus $2,500 to $4,000 for a comparable wood unit that will need sealing and eventual repainting. For the Woodland Hills sun exposure on west-facing patios, vinyl with a UV-stabilized finish holds up better than wood.
• Bundle with another opening. If you also need a front door replacement or window work, doing it in one visit cuts mobilization costs and sometimes the per-unit labor rate. We install from eight product lines (PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux), so we can source everything for one project.
• Get your quote in writing. A clear written price means you can compare line items honestly. No surprise “material adjustments” on the invoice. That is our standard practice, and it protects your budget from day one. Call (831) 618-2053 for a free estimate and we will walk the site and put a hard number in front of you.

How Much Does Patio Door Installation Cost in Woodland Hills by Door Type?

Here is the short version, based on our install volumes in the Valley and the hills:

• Vinyl sliding patio door, 6-foot: $2,800 – $4,500 installed. This is the most common job we do. It is straightforward, fast, and the price holds steady unless the opening has hidden damage.
• Fiberglass sliding door, 6 to 8-foot: $4,000 – $6,500 installed. Fiberglass handles the heat better than vinyl and gives you a nicer feel when opening and closing. PGT makes our most-requested fiberglass slider.
• French swinging patio door, 6-foot: $4,500 – $8,000 installed. Higher labor because both panels have to be hung and aligned perfectly, plus the threshold has to be sealed against wind-driven rain from the coastal side of the hills.
• Multi-slide or wall-of-glass door, 10 to 16-foot: $8,000 – $16,000 installed. This is a luxury project, usually tied to a rear-wall remodel. CGI and ES Windows are the two lines we recommend most here because the engineering tolerances are tight and the wind loads in Woodland Hills canyon lots are real.

Does Hale Windows & Doors Offer Free Estimates?

Yes. Every estimate is free, and every estimate is a written price. We do not do verbal ranges that change once the truck is in the driveway. We come out, measure the opening, check the header, look at the exterior condition, and then hand you a number. That number includes the door, labor, haul-away, and any trim or stucco work we know about at the time of the quote.

You will also know who is coming to your home before they arrive. Every Hale technician is background-checked, identity-verified, and photo-badged. We send you the name and photo of your installer before the visit, so when the knock comes, you already recognize the face. That matters whether you are home alone, have kids napping in the next room, or just do not want to open the door to a stranger. We named this the Threshold Standard, and it is part of every job we do.

What Is the 365-Day Done Right Promise?

It is our installation guarantee, written on every job. If the work is not right, Hale makes it right. No argument, no chargeback negotiation, no fine print about what counts as a defect. You call us, we come back. The promise covers the installation labor and the installation’s effect on the door’s function for a full year from the day we finish.

Beyond that, every repair we do carries a written guarantee. If a repair fails within the covered period, the second visit is free. That is what we mean when we say we put it in writing before anyone picks up a tool.

How Long Does Patio Door Installation Take in Woodland Hills?

A standard slider replacement takes one day, usually 4 to 7 hours from arrival to cleanup. A French door takes a full day to a day and a half because of the dual-panel alignment and sealing work. A multi-slide wall system can take two to four days, depending on the header work and stucco patching. We protect the floor around the work area, run a magnet sweep after the demo, and haul the old door and all packaging with us.

If a permit is required because the opening is changing size, add one to three weeks to the schedule for county review. We submit the drawings and handle the inspection scheduling.

Why Do Patio Door Installation Prices Vary So Much in Woodland Hills?

The spread in pricing comes from the structural reality of the area. Homes built into the hillside have different foundation and shear-wall conditions than homes on flat lots in the Valley floor. South-facing patios get hammered by afternoon heat, so glass package matters more. Canyon-adjacent properties sometimes sit in designated high-wind or brush zones, which pushes homeowners toward impact-rated glass that carries a real premium. And stucco remediation is almost always a factor when the opening changes size.

We give you a fixed price so the variability does not become a problem. The number you approve is the number on the invoice. No “recalculations” after the framing is open.

FAQs – Patio Door Installation Cost

Is it cheaper to repair or replace a patio door?

Repairing a patio door in Woodland Hills typically runs $180 to $500 for things like roller replacement, track cleaning, or lock adjustment. Replacing the door runs $2,800 to $6,500. If the frame is square and the glass is intact, repair is almost always cheaper. If the door is 20-plus years old with a warped frame or failed seal, you are better off replacing. Call (831) 618-2053 and we will tell you honestly which route makes sense for your door.

How much does it cost to replace the sliding door track?

A track replacement on a standard slider runs $300 to $800 installed, including the new track, leveling, and roller adjustment. If the subfloor under the track has water damage (common in older Woodland Hills homes with slab-on-grade foundations), that repair adds $500 to $1,500 depending on the extent of the rot.

Can you install a patio door the same day?

Usually not same-day, but our scheduling is faster than most. We stock common 6-foot sliders and can often install within a week of the estimate. For French doors or custom sizes from PGT or Therma-Tru, lead time is two to six weeks for the door to arrive from the manufacturer. If your door is failing and you need it secure, call (831) 618-2053 and we will talk through temporary fixes and a realistic timeline.

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

Replacing an existing door in the same rough opening rarely requires a permit. If you are widening the opening, cutting into a shear wall, or changing structural headers, a Los Angeles County Building and Safety permit is required, and fees run $150 to $500. We determine this during the estimate and handle the submission if it is needed.

How much does a PGT impact patio door cost installed in Woodland Hills?

A PGT impact-rated sliding patio door installed in Woodland Hills runs $4,800 to $8,500 depending on size and glass package. The impact rating adds about $1,500 to $2,500 over a standard low-E door. For hillside lots in brush or wind zones, the rating is worth the money. For a flat lot near the 101, standard low-E is usually sufficient. Call (831) 618-2053 and we will price both options for your specific opening.
