A sliding glass door costs about $2,500 installed on average, and most homeowners pay between $1,200 and $4,100.1,2,3 The door itself is the biggest part of that. Size, panel count, frame material and glass type move the price far more than labor does.1,3 Prices below are national averages* for 2026.
*National averages, not local quotes. Your price depends on door size, frame, glass, whether the opening needs framing work, and your local labor rates.

Angi puts most common sizes at $10 to $50 per square foot.1 Bob Vila prints a similar size ladder by width, from $400 to $1,400 for a 4-foot door up to $1,300 to $3,500 for 16 feet.2 Those two guides also share the same style and frame tables, so treat them as one dataset rather than two confirmations.
Cost by number of panels (This Old House)
| Panels | Range | Average |
|---|---|---|
| Two-panel | $400 – $1,500 | $950 |
| Three-panel | $1,500 – $3,500 | $2,500 |
| Four-panel | $2,500 – $5,500 | $4,000 |
| Five-panel | $3,000 – $6,000 | $4,500 |
| Six-panel | $3,500 – $6,500 | $5,000 |
This Old House quotes a wider overall range, $600 to $10,000, with a $2,500 average. That is close to Angi’s average even though the ranges differ.3
Frame material
| Material | Angi | This Old House (average) |
|---|---|---|
| Vinyl | $300 – $1,200 | $500 |
| Aluminum | $750 – $2,500 | $800 |
| Composite | $600 – $1,200 | $900 |
| Wood | $1,000 – $3,000 | $1,000 |
| Fiberglass | $1,500 – $2,500 | $1,500 |
Vinyl is cheapest in both. Fiberglass is the priciest of the five and Angi notes it is harder to DIY.1,3

Labor and repair
| Item | Cost | Source |
|---|---|---|
| Installer rate | $70 – $100 per hour | Angi |
| Full installation labor | $300 – $800 | Angi |
| Pro install, Yelp quotes | $300 – $900 | Yelp |
| Replace glass only | $250 – $1,000 | Angi |
| Window tinting | $5 – $30 per sq ft | Angi |
Yelp’s 283 quotes for patio door installation show a typical price of $497, with the high end at $2,700. That is much lower than the guides because many quotes are partial jobs, so I use it only for the labor line.4
DIY or hire
Doing it yourself can save the $300 to $800 labor line, but Angi warns that mistakes are costly to fix, and a heavy glass door needs two people.1 Repairs are different: replacing worn rollers and tracks is a reasonable DIY job. Home Depot’s sliding patio door category lists standard sizes like 72 x 80 so you can compare retail prices before you get quotes.
