How much does a sliding glass door cost to replace?
Typical ranges, repair vs. replace, and what to look for in a new patio door.

Short answer: a new front door often costs anywhere from under $1,000 to around $3,000 or more, installed. Steel doors sit at the lower end and fiberglass in the middle to upper range. Custom wood, double doors, sidelights and decorative glass can push the price well beyond that.
Angi's August 2026 figures for Texas (Austin) list these door-only ranges, before installation:
The same data lists labor at about $30 to $90 an hour, which Angi says makes up nearly a third of a typical project. Reframing a damaged opening adds more. Not sure which material fits your home? Read fiberglass, steel or wood for Texas weather.
Garage-to-house doors and French doors are often replaced along with the front door. Doing them together can save a trip. See all entry doors
A well-hung insulated door stops drafts, quiets the entry and changes how your home looks from the street. The U.S. Department of Energy notes that insulated steel and fiberglass doors have more than five times the insulating value of a solid wood door. If you want to spread out the cost, see financing.
