Installation and extras
| Item | Typical cost |
|---|---|
| Professional installation | $300–$800 ($70–$100 per hour) |
| Removing the old door | $100–$250 |
| Doors wider than 8 feet | About $100 per linear foot of width |
| Cutting a new opening where there was no door | $1,000–$3,600, not including the door |
Rotted sill framing or subfloor at the threshold is a common surprise with old sliders. Ask for a price if they find it.
Repair or replace?
- Repair if the door is hard to slide (rollers and track can often be cleaned, adjusted or replaced), the lock is broken, or a single glass panel is broken and the frame is sound.
- Replace if the frame is bent or rotted, the door leaks or is drafty, the glass seals have failed on an old door, or you want better security or energy efficiency.
Options to compare
- Low-E, double-pane or impact-rated glass.
- Multipoint locks and a secondary foot lock.
- Built-in blinds between the glass.
- Hinged French patio doors instead of sliders, if you have swing space.
