AfterHow Much Does Patio Door Installation Cost in Los Angeles?
Patio door installation in Los Angeles typically runs $3,200 to $8,500 for a standard sliding glass door, and $4,800 to $14,000 if you’re replacing it with a French or folding door. Figure on $3,000 to $5,000 for the most common job we see here: a like-for-like slider swap in a 1960s ranch house, single-story, with the original opening still square. Impact-rated glass, which most of Los Angeles County now requires in new door permits, adds $700 to $1,600 to the door itself.
Those ranges include the door, the labor, disposal of the old unit, and permit fees. What they don’t include is stucco repair, framing corrections, or a new header, which is where Los Angeles projects occasionally go sideways. We’ll show you exactly where your project lands before anyone touches a screwdriver.

Patio Door Installation Cost Breakdown (2026)
Here’s how the money actually breaks down on a Los Angeles patio door project. These are installed prices, not door-sticker prices.
| Line Item | Typical LA Range |
|---|---|
| Standard sliding glass door (6 ft, vinyl or aluminum frame) | $1,400 – $3,200 |
| Mid-grade slider with better U-factor and hardware | $2,800 – $5,000 |
| French door set (double, hinged) | $3,500 – $7,500 |
| Folding / multi-slide door (2 to 4 panels) | $6,000 – $18,000+ |
| Impact-rated glass upgrade | $700 – $1,600 |
| Low-E coating and argon fill | $200 – $500 |
| Labor and installation | $900 – $2,400 |
| Removal and disposal of old door | $150 – $350 |
| City of Los Angeles permit | $250 – $600 |
| Stucco repair and patching around opening | $400 – $1,200 |
| Framing or header correction (if needed) | $600 – $2,500 |
| New threshold and flashing | $250 – $600 |
The single biggest swing factor is what you’re putting in. A basic slider in a rental in Van Nuys and a four-panel folding door opening onto a Westside patio are the same category of project and nowhere near the same price. After that, it’s condition of the rough opening. In older Los Angeles housing stock, the studs behind the stucco have often moved, and sometimes the header was never sized for the door someone installed in 1978. We open the wall and find out. That’s why we price framing as a line item instead of bundling it into a vague “additional work” clause.
If you want the full picture of how we scope these projects, our Patio Door Installation in Los Angeles page walks through the process start to finish.
What Affects Patio Door Installation Pricing in Los Angeles
- Impact-rated glass requirements. Much of Los Angeles County sits in a wind-borne debris region, and permitted replacements generally need impact-rated glazing. That’s not a sales upsell, it’s code. Expect $700 to $1,600 over standard glass, and expect us to check your address before we quote.
- Door type and panel count. Every additional operating panel on a multi-slide adds hardware, track, and labor. A two-panel slider is a half-day job. A four-panel folding system with a flush track is two days and a different crew.
- Wall construction and stucco. Most LA homes are stucco over wood frame, and stucco doesn’t release a door cleanly. Patching and re-texturing runs $400 to $1,200. Homes in the hills with raised foundations sometimes need extra flashing work where the exterior grade drops away.
- HOA and historic district review. If you’re in a historic overlay or a condo association, the approval process can add weeks and occasionally forces a specific door style or color. That’s a timeline cost more than a dollar cost, but it matters.
- Access and staging. A narrow side yard in Highland Park or a third-floor condo in Koreatown changes how the door gets to the opening. We’ve hand-carried units up stairwells. That gets priced in.
- Time of year. Spring and early summer are our busiest months. Scheduling in late fall or winter often means more flexibility and occasionally a better price on certain product lines.
We stock and install across eight product lines, including PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. Having that many options on the shelf means we’re not forcing your opening into the one door a single manufacturer happens to make. If a Therma-Tru hinged door fits your Spanish Colonial remodel better than a slider, you get the Therma-Tru.
How to Save on Patio Door Installation
There’s no secret coupon here, but there are real ways to keep the number down.
- Keep the opening size. If your new door matches the old rough opening, you skip framing and stucco work entirely. That alone can save $1,000 to $3,500.
- Choose a standard size. Custom-width doors carry a lead-time and price premium. A stock 6-foot slider is the cheapest door you can buy.
- Skip the impact upgrade only if your address allows it. We’ll check. If you’re outside the wind-borne debris region, standard glass is fine and saves real money.
- Bundle with windows. If you’re already replacing windows on the same elevation, the crew is there, the permit is open, and the stucco work is happening anyway. It’s the cheapest door you’ll ever add.
- Get the price in writing before you commit. This is the one that matters most. A verbal estimate that “adjusts” once the wall is open is how homeowners end up $2,000 over budget. We hand you a written price before any work starts, and that number holds.
Free estimates are genuinely free. Call (682) 281-2168 and we’ll look at your opening, check your address against the impact requirements, and give you a real range, not a teaser number.
Why Los Angeles Patio Door Pricing Runs Higher Than National Averages
National cost guides will quote you $2,000 to $5,000 for a patio door. Los Angeles runs above that, and it’s not arbitrary. Three things push it up.
First, permitting. The City of Los Angeles requires a permit for exterior door replacement, and the review process takes time. Some neighboring jurisdictions, including Santa Monica and Pasadena, have their own requirements layered on top. We handle the paperwork, but the fee and the timeline are real.
Second, impact glazing. A large share of LA County falls into areas where permitted doors need impact-rated glass. That’s a meaningful cost increase over standard tempered glass, and there’s no way around it on a permitted job.
Third, labor. Skilled installers in Los Angeles cost more than they do in most markets because the cost of living here is higher. You’re paying for someone who knows how to flash a threshold correctly on a stucco wall, and that skill is worth paying for. A badly flashed door leaks into your wall for years before you notice.
Repair or Replace? A Quick Way to Decide
If your existing door is under 15 years old and the frame is sound, repair usually wins. Rollers, tracks, locks, and weatherstripping are all replaceable, and a repair visit typically runs $150 to $450. We’ll do that work and skip the sales pitch.
Replace when any of these are true:
- The frame or sill is rotted. Water damage doesn’t stay contained.
- The glass is fogged between panes. That means the seal failed and the insulating value is gone.
- The door no longer closes squarely, which usually points to a shifted header or foundation movement.
- You’re doing it for energy reasons. A door from the 1990s has a U-factor roughly double what you can buy today, and on a west-facing wall in the San Fernando Valley, that difference shows up on your July bill.
- You want a bigger opening. Going from a slider to a multi-slide or folding door is a replacement project by definition.
A repair that fails is covered by a free second visit, no charge. If we can fix it, we’ll tell you.
How Long Does Installation Take in Los Angeles?
A standard slider replacement is a one-day job, generally six to eight hours. A French door set is one to two days. A folding or multi-slide system is two to three days, plus lead time on the door itself, which runs four to ten weeks depending on the product line and finish.
Permit processing in the City of Los Angeles adds time before the install, not during it. We pull the permit as early as possible so the door and the approval arrive around the same time. You’ll get a live arrival time on install day, and photos of the finished work when we’re done, so you’re not guessing about progress from your kitchen.

FAQs – Patio Door Installation Cost
How much does patio door installation cost in Los Angeles?
A standard sliding glass door installed in Los Angeles runs $3,200 to $8,500. French doors land between $4,800 and $14,000 depending on size and finish. Impact-rated glass, required for most permitted replacements in LA County, adds $700 to $1,600. Call (682) 281-2168 for a written range for your exact opening, free.
Is it cheaper to repair or replace a patio door?
Repair is cheaper when the frame is sound: $150 to $450 for rollers, tracks, locks, or weatherstripping. Replacement makes more sense once the sill or frame is rotted, the glass is fogged, or the door no longer closes square. Those are all replacement signals, and patching over them costs more later. Call (682) 281-2168 and we’ll tell you which one you actually need.
Do I need a permit to replace a patio door in Los Angeles?
Yes, the City of Los Angeles requires a permit for exterior door replacement, and the fee generally runs $250 to $600. Some neighboring cities layer their own requirements on top. We pull the permit for you as part of the project, and the fee shows up as a line item on your written price rather than a surprise later.
How much does impact-rated patio door glass add in Los Angeles?
Impact-rated glass adds $700 to $1,600 to the door cost, and it’s required for most permitted replacements in LA County’s wind-borne debris region. It’s built to resist wind-borne debris without shattering. If your address falls outside the requirement, we’ll tell you, and standard glass saves you the difference.
Can you install a patio door in one day?
A standard slider is a one-day job, usually six to eight hours. French doors take one to two days, and folding or multi-slide systems take two to three. Door lead time runs four to ten weeks depending on the product line. Call (682) 281-2168 and we’ll give you a real install date, plus a live arrival time on the day.
What’s the cheapest patio door I can install in Los Angeles?
A stock six-foot sliding door in a standard-size opening, without impact glass, is the lowest-cost path, and installed it typically lands near the bottom of the $3,200 to $8,500 range. Keeping your existing rough opening is the single biggest saver, since it skips framing and stucco repair. Call (682) 281-2168 and we’ll price the leanest option that still meets code at your address.
