What does a sliding patio door cost?
Quick answer
HomeGuide puts a sliding patio door at $1,200 to $4,000 installed in most homes. A full patio door replacement, including hauling away the old unit, runs $700 to $6,500. Where the price lands depends on the width, the number of panels, the frame material and whether a wall has to be opened to make room.
Here are GOLDGCP's national planning ranges for each kind of door. Enter your ZIP code on this page and they adjust to your local market.
| Job | US average (typical range) | Typical |
|---|---|---|
| Entry door, installed | $700–$3,500 | $1,600 |
| Double entry doors, installed | $1,500–$6,500 | $4,000 |
| Patio sliding door | $1,500–$6,000 | $3,000 |
| French doors | $2,000–$7,500 | $4,000 |
| Multi-slide or bi-fold door | $5,000–$22,000 | $10,000 |
| Garage door | $900–$4,000 | $1,800 |
| Storm door | $400–$1,100 | $750 |
| Interior door, installed | $120–$570 | $350 |

Where the money goes
A patio door bill has three parts. HomeGuide's breakdown:
| Part of the job | Typical cost |
|---|---|
| The door unit and materials | $400 to $5,000 |
| Installation labor | $200 to $1,000 |
| Removing and disposing of the old door | $100 to $500 |
| Total for a replacement | $700 to $6,500 |
Labor stays fairly steady. The door itself causes most of the spread, so the choices below matter more than which crew you hire.
Sliding door prices by quality
HomeGuide sorts sliders into three tiers. These prices are for the door only.
| Tier | Door price | What you get |
|---|---|---|
| Basic | $300 to $800 | Aluminum or vinyl frame, standard size, single-pane glass |
| Mid-range | $800 to $2,000 | Double-pane glass, low-E coating, wood or clad frames, many ENERGY STAR models |
| High-end | $2,000 to $5,000 | Fiberglass, custom sizes, triple-pane or impact glass |
A single-pane slider costs the least but is the weakest choice for comfort. In most of the country, a double-pane, low-E door from the mid-range tier is the practical floor for a door that sits next to a living room.
Price by number of panels
| Panels and width | Door only | Door plus install |
|---|---|---|
| 2 panels, 5 to 8 feet | $300 to $2,200 | $500 to $2,600 |
| 3 panels, about 9 feet | $700 to $4,000 | $1,000 to $4,500 |
| 4 panels, about 12 feet | $1,900 to $5,000 | $2,300 to $5,800 |
On a standard two-panel slider, one panel is fixed and one moves. When you want most of a wall to open, look at our page on multi-slide and bi-fold doors, which covers stacking and pocketing systems.
Price by frame material
| Frame | Door price | Notes |
|---|---|---|
| Vinyl | $400 to $1,200 | Popular and water resistant; can warp in strong heat |
| Aluminum | $600 to $2,500 | Light and more durable than vinyl, but dents |
| Fiberglass | $800 to $3,500 | Durable and low maintenance |
| Wood | $1,000 to $5,000 | Insulates well and looks traditional; needs regular upkeep |
Replacing a slider vs. cutting a new opening
The biggest cost jump comes from structural work. HomeGuide prices three common scenarios:
| Project | Typical cost |
|---|---|
| Swap an old slider for a new one in the same opening | $800 to $2,000 |
| Fit a slider into an existing door or window opening that needs changes | $1,100 to $2,600 |
| Cut a new opening in a solid wall and install the door | $1,400 to $3,500 |
A new opening brings extra line items: a permit ($75 to $500), a structural engineer if the wall is load bearing ($300 to $1,000), cutting the opening ($400 to $1,500) and framing it ($230 to $600). Moving wiring or pipes that run through the wall can add up to $1,200.
HomeGuide notes that hidden damage often turns up only after the old door comes out, such as wet framing under a worn sill. Budget for some rough framing at $7 to $20 per linear foot, plus a new threshold at $25 to $50, until the old door is out and the installer can see the opening.
Sizes and handing
A typical sliding patio door is 60 to 72 inches wide and 80 inches tall, and HomeGuide lists 72 by 80 inches as the standard patio door. Doors can run from 30 to 96 inches wide and up to 96 inches tall, and custom sliders reach about 12 feet wide.
Order the right hand. Sliders come as left-handed or right-handed models, and HomeGuide notes that a door with its handle on the left side is a right-handed door. Getting this wrong can leave the fixed panel on the side where your furniture or grill sits.
Repair or replace?
Some problems don't need a new door. HomeGuide's repair prices, labor included:
- New rollers and track: $100 to $300
- New screen: $130 to $550
- One replacement panel: $450 to $700, if the rest of the door is sound and the new panel comes from the same maker in the same size
- New glass: $200 to $1,200
Replace the whole unit when the frame is cracked or rotted, the glass fogs between panes, water gets in during rain, or drafts remain after new weatherstripping. Patio doors usually last 20 to 30 years, so a door from the 1990s is near the end of its life even if it still slides.
Energy ratings for sliding glass doors
ENERGY STAR treats sliding glass doors like windows: the limits depend on your climate zone. These are the Version 7.0 limits, in effect since October 23, 2023.
| ENERGY STAR climate zone | Maximum U-factor | Solar heat gain coefficient |
|---|---|---|
| Northern | 0.22 | 0.17 or higher |
| North-Central | 0.25 | 0.40 or lower |
| South-Central | 0.28 | 0.23 or lower |
| Southern | 0.32 | 0.23 or lower |
Sliding doors must also leak no more than 0.3 cubic feet of air per minute per square foot in testing. In the north the program wants the glass to let in some winter sun, while in the south it wants that heat blocked, which is why the solar heat gain rule flips direction. Compare the NFRC label on each quoted door with the row for your zone.
Safety glass and impact glass
Every pane in a patio slider must be safety glass. The federal standard, 16 CFR Part 1201, lists sliding glass doors as Category II products, the group that must survive a 400 foot-pound impact test. The International Building Code also treats glass in both the fixed and the moving panels of a sliding door as a hazardous location, and it requires a permanent mark on each safety pane.
In hurricane regions, local code may also require impact-rated doors or protection. HomeGuide puts hurricane-rated sliders at $1,000 to $3,000, with larger three-panel units reaching about $7,000. See our guide to impact windows for how impact glass is tested and labeled.
Making a slider more secure
The stock latch on many sliding doors is light duty. HomeGuide prices high-security add-ons, such as a foot lock, a floor-level deadbolt or a security bar in the track, at $40 to $200. When you buy a new door, ask whether it has a multipoint lock and whether the moving panel can be lifted out of the track from outside when it is closed.

How to hire a patio door installer
- Measure the existing opening, or let the installer do it, before you choose a size. A door that is too large for the opening won't work.
- Ask whether the quote covers removal, disposal, sill pan flashing, interior trim and exterior trim.
- Ask who pulls the permit if the opening changes size, and whether a structural engineer is needed.
- Get the model, frame material, glass package, NFRC ratings and handing in writing.
- Ask how the installer will protect your floors and what happens if they find rot under the old sill.
Through GOLDGCP you get matched with 3 vetted, licensed pros. Each one has passed a state license check, an insurance check, a background and business check, a portfolio review, client reference calls and onboarding with a quality score.

Frequently asked questions
How much does it cost to replace a sliding glass door?
Swapping an old slider for a new one in the same opening usually costs $800 to $2,000, according to HomeGuide. Across all patio door replacements, including removal of the old unit, the range is $700 to $6,500. Wider multi-panel doors and impact glass sit at the top of that range.
How much does it cost to put a sliding door in a wall?
Cutting a new opening in a solid wall and installing a slider costs about $1,400 to $3,500. That covers the opening, framing and the door. Expect separate charges for a permit, an engineer if the wall carries load, and up to $1,200 if wiring or pipes must move.
How long does a patio door last?
HomeGuide puts the life of a patio door at 20 to 30 years. Sun exposure, the frame material and how often the door is used all affect that. Cleaning the track and replacing worn rollers and weatherstripping can keep an older door working longer.
Can I replace just one panel of a sliding door?
Often, yes. Replacing a single panel costs about $450 to $700. The new panel must be the same size and usually from the same manufacturer, so it fits the existing frame and track. If the frame itself is damaged, replacing the whole door is usually the better value.
Do sliding patio doors need safety glass?
Yes. Federal rule 16 CFR Part 1201 classes sliding glass doors as Category II products, which must pass a 400 foot-pound impact test. Building codes treat glass in both panels of a slider as a hazardous location, and each pane must carry a permanent safety mark.
What U-factor should a sliding patio door have?
Under ENERGY STAR Version 7.0, a sliding glass door needs a U-factor of 0.22 or lower in the Northern zone, 0.25 in North-Central, 0.28 in South-Central and 0.32 in the Southern zone. Lower numbers mean less heat moving through the door.
How long does it take to install a patio door?
Most patio door installs take 3 to 6 hours, including removing the old door and making small repairs. A job can stretch to a full day for a large door, and longer if the wall needs a new opening and header.
How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). For ZIP codes outside the 50 largest metros, the calculator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
