$1,200 – $4,000That is the typical patio door replacement cost in 2026 for a standard sliding glass door, installed (HomeGuide). Across every patio door type, HomeGuide puts a replacement at $700 to $6,500. Fixr quotes $2,000 to $4,000 for a sliding door, while Homewyse starts lower, at $1,017 to $1,551 for a basic vinyl slider.
The door type sets most of the price. A sliding door in an opening that is already the right size is the cheap case. Swinging French doors cost more, and folding or multi-slide systems cost several times as much. The tables below set the published guides side by side so you can see where they agree and where they do not.
Patio door replacement cost by door type
| Door type | HomeGuide patio door guide | HomeGuide door-specific guides | Fixr and Homewyse |
|---|---|---|---|
| Sliding | $1,200 – $4,000 | $700 – $2,400 (replacement) | Fixr $2,000 – $4,000; Homewyse $1,017 – $1,551 |
| French | $600 – $5,500 | Exterior $1,300 – $5,500; replacement $2,500 – $7,000 | — |
| Telescoping (multi-slide) | $1,500 – $5,000 | Sliding glass wall $5,000 – $20,000 | Fixr $2,500 – $10,000 |
| Folding or bifold | $5,000 – $20,000 | $6,400 – $24,000 (folding guide) | — |
Even one publisher disagrees with itself. HomeGuide’s patio door guide gives $1,200 to $4,000 for a sliding door, but its sliding door guide says $700 to $2,400, and that guide lists French doors at $700 to $1,800 while its patio door guide says $600 to $5,500 and its French door guide $1,300 to $5,500 for exterior ones. The Homewyse figure is a basic double-pane vinyl slider with low-E glass, so it sits at the bottom. Fixr’s $2,000 to $4,000 is for installing a 6-foot-wide door, and its average of $2,756 is for a 72” x 80” aluminum door.
HomeGuide says French doors take up more space than sliding doors, and says bifold doors give a larger opening but cost more. A sliding door is the budget choice. HomeGuide says patio doors last 20 to 30 years with proper care.
Our estimate: for a standard 6-foot sliding door replaced in an opening that already fits, the lowest figure among the guides is $900 (HomeGuide’s sliding door table) and the highest is $4,000. This is a range we combined from published figures, not a measured price.
Estimate your patio door replacement cost
Our estimate: the published ranges above multiplied out for your inputs. Not a quote. Door types from HomeGuide’s patio door guide (October 2025), except exterior French doors (its French door guide) and the basic 6 ft slider (its sliding door guide), both February 2026. Fixr (January 2025) is higher for sliding doors and Homewyse (May 2026) lower. Removal ($100 to $500 in HomeGuide’s patio guide) is listed apart from the installed-door figures; ask whether your quote already includes it. Framing is HomeGuide’s $150 to $250 or more; cutting a brand-new opening costs more (see the labor section). State adjustment: BLS construction wages (May 2025), applied to an assumed 50% labor share. How we calculate
Sliding glass door cost by size
| Door width | Door only | Total replacement |
|---|---|---|
| 5 ft | $400 – $800 | $700 – $1,400 |
| 6 ft | $600 – $900 | $900 – $1,500 |
| 8 ft | $700 – $1,000 | $1,100 – $1,600 |
| 10 ft | $950 – $1,200 | $1,350 – $1,900 |
| 12 ft | $950 – $1,300 | $1,400 – $2,000 |
| 15 ft | $1,300 – $1,600 | $1,800 – $2,500 |
Because the door-only columns match, treat them as one set of data, not two. Totals here are much lower than the type table above, since they assume a basic aluminum frame. For large doors, HomeGuide puts 8 to 12 feet wide at $4,000 to $7,000 (custom, oversized doors at $900 to $1,200 per linear foot), and Fixr puts an oversized door at $4,000 to $7,000, including about $100 per linear foot for installation. That clashes with the table, where an 8-foot door totals $1,100 to $1,600, so ask any installer whether a quote is for a basic or an oversized, custom door.
Patio door cost by frame material
| Frame material | HomeGuide patio door guide | HomeGuide sliding guide | Fixr |
|---|---|---|---|
| Vinyl | $400 – $1,200 | $300 – $2,000 | $300 – $700 |
| Aluminum | $600 – $2,500 | $250 – $1,600 | $600 – $1,000 |
| Fiberglass | $800 – $3,500 | $400 – $2,000 | $1,500 – $2,500 |
| Wood | $1,000 – $5,000 | $1,000 – $2,200 (solid wood) | $500 – $1,500 |
Vinyl has the lowest starting price in two of the three tables; HomeGuide’s sliding guide has aluminum lower, at $250. HomeGuide says vinyl can warp in heat, aluminum dents, fiberglass can crack over time, and wood needs the most upkeep but insulates well. Fixr adds that aluminum conducts heat and tends to produce more condensation. Glass changes the price too: for the door alone, Fixr lists low-E glass at $100 to $500, gas-filled glass at $400 to $600 and triple-pane at $2,000 to $3,000.
Labor, removal and resizing the opening
| Item | HomeGuide | Fixr |
|---|---|---|
| Installation labor | $200 – $1,000 (patio guide); $300 – $500 (French) | $65 – $85 an hour, about 7 hours |
| Removing and disposing of the old door | $100 – $500 (patio guide); $100 – $250 (sliding) | $100 – $300 |
| Frame repair or replacement | — | $100 – $300 |
| Framing a new or larger opening | $150 – $250 or more | $300 – $600 |
| Cutting a brand-new opening in the wall | — | $400 – $1,500, plus permits and engineer $300 – $1,500 |
| Permit, folding doors | $100 – $500 | — |
A swap in the existing opening is the easy job. HomeGuide says it takes 3 to 6 hours, and Fixr says installing a door where there was no opening runs $1,500 to $5,000 in total. If the wall is load-bearing, Fixr says only experienced carpenters or structural engineers should decide whether the opening can be widened. HomeGuide says creating a new opening for a folding door can double or triple the project cost.
ENERGY STAR doors and the federal tax credit
ENERGY STAR doors are tested, certified and verified by the National Fenestration Rating Council, and their ratings must meet EPA guidelines. Unlike windows, doors are not rated by climate zone: the criteria depend on how much glass the door has and on its NFRC ratings. ENERGY STAR notes that even a door with lots of glass, such as a sliding patio door, has a lower glass-to-frame ratio than a window (ENERGY STAR; criteria tables dated October 2023, so older than 2025).
The tax credit is gone for 2026. The federal credit for exterior doors was $250 per door and $500 in total (IRS, page reviewed April 28, 2026). The IRS says the credit “will not be allowed for any property placed in service after December 31, 2025” (IRS FS-2025-05, August 21, 2025). ENERGY STAR’s own page limits it to products purchased and installed from January 1, 2023 to December 31, 2025 (ENERGY STAR). A door installed this year does not qualify. Ask your state or utility about rebates; we did not verify any.
Repairing instead of replacing
If the frame is sound, a part may be enough. HomeGuide lists glass at $200 to $1,200, a single sliding panel at $450 to $700, a screen at $130 to $550, and rollers and tracks at $100 to $300, all with labor. It suggests asking a repairer whether damaged parts can be replaced instead of the whole door. A replacement panel must be the same size and from the same manufacturer.
Doing it alongside other exterior work
Patio doors often get replaced with the windows around them. See our guides to window replacement cost and energy-efficient windows cost. If new trim or a wider opening disturbs the wall, check the siding replacement cost guide before you sign.
How to keep the bill down
- Keep the same size and type. HomeGuide says a standard door is 72” x 80” and that a smaller opening than the new door needs reframing.
- Choose vinyl or aluminum unless you need the insulation or look of wood or fiberglass.
- Repair rollers, tracks or glass first if the frame is sound.
- Skip add-ons you do not need. Fixr prices hurricane-rated glass at $1,000 to $3,000 for the door alone.
- Get at least three written estimates, as HomeGuide recommends, and compare the same scope in each. HomeGuide also warns that the cheapest quote can signal lower quality.
Questions to ask before you sign
- Is the price for the door only, or for the door, labor, removal and trim?
- Does the opening need reframing, and who pulls the permit?
- Is the door ENERGY STAR certified, and what are its NFRC ratings?
- What frame material and glass are in the quote, and is the screen included?
- Are you licensed and insured, and is there a written warranty on the door and the work?
