Patio Door Replacement Cost by Type and Material
The style of door sets the baseline, and the frame material moves it up or down from there. Prices below are installed, include removal of the old door, and assume the new unit fits the existing rough opening.
| Door type | Vinyl | Fiberglass | Wood / clad wood |
|---|---|---|---|
| Sliding, 2 panels (6 ft) | $1,300–$3,400 | $1,750–$4,600 | $2,200–$5,800 |
| Sliding, 3–4 panels (9–12 ft) | $2,300–$5,900 | $3,100–$8,000 | $3,900–$10,000 |
| French (hinged pair) | $1,500–$4,400 | $2,000–$5,900 | $2,550–$7,500 |
| Multi-slide / telescoping | $2,600–$6,900 | $3,500–$9,300 | $4,400–$11,700 |
| Bifold / folding glass wall | $5,100–$15,400 | $6,900–$20,800 | $8,700–$26,200 |
A standard two-panel vinyl slider is by far the most common replacement, and most homeowners pay about $1,300 to $3,400 for one, with a typical cost around $2,250. Across all door types, Angi and This Old House both put the national average near $2,500, and HomeGuide’s replacement range runs from about $700 to $6,500.
Sliding vs. French patio doors
Sliding doors are usually the cheaper and more practical pick. They don’t need swing clearance, so furniture can sit close to the glass, and a two-panel slider gives you a wide, uninterrupted view. HomeGuide prices installed sliders at $1,200 to $4,000.
French doors swing open on hinges, either inward or outward, and create a wider walk-through opening when both leaves are open. They cost more on average because each panel needs a full frame, hinges, and multipoint locking hardware. They also need clear floor space to swing, which matters on a small deck or in a tight dining room.
Multi-slide and folding doors
Telescoping multi-slide doors stack three or more panels behind each other, and bifold doors fold panels accordion-style to open most of a wall. They’re popular for indoor-outdoor living spaces, but they’re premium products. HomeGuide lists bifold doors at $5,000 to $20,000, and a large opening almost always needs structural work that adds to the bill.
Frame materials compared
- Vinyl: the budget standard. Low maintenance and reasonably efficient, but frames are thicker and color choices are limited.
- Aluminum: slim, strong frames that suit modern homes and large glass panels. Look for thermally broken frames in cold climates.
- Fiberglass or composite: very stable through temperature swings, paintable, and efficient. Costs more than vinyl.
- Wood and clad wood: the warmest look, with aluminum or vinyl cladding on the outside to protect it from weather. The priciest option and the one that needs the most care.
Cost Breakdown: Materials vs. Labor
On a standard slider, the door unit is the bigger share of the bill, and labor stays fairly steady regardless of brand.
| Item | Typical cost |
|---|---|
| Door unit, 2-panel vinyl slider | $300–$1,200 |
| Door unit, fiberglass or clad wood | $800–$5,000 |
| Installation labor | $400–$1,400 |
| Removal and disposal of the old door | $100–$400 |
| Screen door | $100–$550 |
| Low-E or upgraded glass | $100–$500 |
Big-box retailers publish their install pricing too: Home Depot lists patio door installation labor at about $498 to $1,298 for standard doors and up to $1,918 for oversized models. Most crews finish a straightforward replacement in 3 to 6 hours.
A complete installation quote should cover pulling the interior trim, removing the old unit, preparing and flashing the sill, setting and shimming the new door, sealing the gaps with low-expansion foam, and reinstalling or replacing the trim. Painting new trim and wrapping the exterior frame in aluminum capping are often extras, so check what each bid includes before comparing totals.
Other Factors That Affect Patio Door Cost
Changing the size of the opening
Swapping a door into the same rough opening is the cheapest path. Widening an opening, converting a window to a door, or going from a 6-foot slider to a 12-foot multi-slide means cutting framing, installing a properly sized header, and patching siding, drywall, and flooring. In a load-bearing wall, you’ll need a permit and sometimes an engineer’s sign-off, and the carpentry can cost as much as the door.
Glass package
Double-pane low-E glass is standard on most new doors. Triple-pane glass, laminated or impact-rated glass for hurricane zones, and built-in blinds between the panes all raise the price. This Old House notes soundproof glass packages can run $1,200 to $4,000.
Rot and water damage
Old patio doors that leaked often leave behind soft subfloor, a rotted sill plate, or damaged framing. The installer can’t see it until the old door is out, so ask how repairs will be priced before work starts.
Custom sizes and colors
Stock sizes (such as 72 x 80 inches) are cheapest. Custom widths, taller doors, dark exterior colors, and specialty hardware finishes add cost and can stretch lead times to several weeks.
Location and access
Second-floor balcony doors, doors that open onto a raised deck, and homes in high-cost metro areas all push labor up. Use the region selector in the calculator above to adjust for your area.
What to Look for in a Replacement Patio Door
A patio door is essentially a very large window, so the same performance labels apply. Comparing them helps explain why two doors of the same size can be hundreds of dollars apart.
- U-factor: measures how much heat passes through the whole door. Lower is better, and it matters most in cold climates.
- Solar heat gain coefficient (SHGC): measures how much solar heat the glass lets in. A low SHGC helps keep south- and west-facing rooms cooler in hot climates.
- ENERGY STAR certification: means the door meets efficiency criteria set for your climate zone, and it’s usually the requirement for utility rebates.
- Air leakage and water ratings: check the NFRC label and the manufacturer’s performance grade, especially for exposed doors on the windward side of the house.
- Locking hardware: multipoint locks on French doors and a secondary foot lock or bar on sliders make a real difference to security.
Warranty terms also vary widely. Look for separate coverage on the frame, the glass seal, and the hardware, and ask whether installation labor is covered.
Before you hire: get at least three written, itemized quotes from licensed and insured local pros. Prices for the same job often differ by 30% or more, and comparing line items is the fastest way to spot padding or missing work.
Repair or Replace Your Patio Door?
A slider that sticks or drags doesn’t automatically need replacing. Worn rollers and dirty tracks are cheap fixes; HomeGuide puts new rollers and tracks at about $100 to $300. A single foggy or cracked glass panel can often be replaced for $200 to $1,200 instead of buying a new door.
Replacement is usually the better call when:
- The frame is warped, cracked, or rotted and the door no longer seals.
- You feel drafts or see condensation between the panes of an older single- or early double-pane unit.
- The locks are weak or broken and replacement hardware is no longer available.
- You’re replacing windows nearby and want matching frames and glass; see our window replacement cost guide.
Should you install a patio door yourself?
Experienced DIYers can replace a slider in an existing opening, but a glass door panel is heavy, and the job depends on getting the sill level, flashed, and sealed so water doesn’t get into the floor. A poorly flashed door can cause rot that costs more than the installation you saved on. Many manufacturers also tie their warranties to proper installation. For anything involving a new opening, hire a pro and pull a permit.
How to Save Money on Patio Door Replacement
- Keep the existing opening. A same-size replacement avoids framing, drywall, and siding work.
- Choose vinyl for a basic slider. It delivers solid energy performance for far less than wood or fiberglass.
- Stick to stock sizes and standard colors to avoid custom-order premiums and delays.
- Check utility rebates. The federal 25C tax credit for efficient doors ended for property placed in service after December 31, 2025, but some utilities and state programs still offer rebates for ENERGY STAR doors.
- Bundle with windows. Installers often discount doors added to a whole-house window order.
- Collect at least three quotes that specify the same brand, series, and glass package.

Frequently Asked Questions
How much does it cost to replace a sliding glass door?
A two-panel sliding glass door typically costs $1,300 to $3,400 installed in vinyl, with about $2,250 being common. Fiberglass or clad-wood sliders of the same size usually run $1,750 to $5,800.
Are French doors more expensive than sliding doors?
Usually, yes. A vinyl French door pair typically costs $1,500 to $4,400 installed versus $1,300 to $3,400 for a comparable slider, because each hinged panel needs its own frame and locking hardware.
Can you replace a patio door without replacing the frame?
Sometimes. If only the glass or rollers have failed, you can replace a glass panel ($200 to $1,200) or the rollers and track ($100 to $300). Most full replacements swap the entire door unit, including the frame, into the existing rough opening.
How long does it take to install a patio door?
A same-size replacement usually takes 3 to 6 hours. Enlarging the opening, repairing rot, or installing a multi-slide or folding door can take one to several days.
Is there a tax credit for patio doors in 2026?
The federal Energy Efficient Home Improvement Credit (25C) no longer applies to doors placed in service after December 31, 2025. Check with your utility and state energy office, since some still offer rebates for ENERGY STAR certified doors.
What is the cheapest patio door to install?
A standard-size, two-panel vinyl sliding door installed in the existing opening is the least expensive option. Door units start around $300 to $1,200, and labor typically adds $400 to $1,400.
