The Average Cost of a Sliding Door Installation

Expect to spend an average of $500 to install a standard six-foot wide, two-panel sliding glass door or patio door. However, industry estimates for this installation range from $350 to more than $1,200. You'll also need add the cost of the door itself to the installation price.


The Average Cost of a Sliding Door Installation

On average, two patio doors will cost $1,000 to $2,000; the price depends on the size, special features and type of manufacturing material.  Doors come in vinyl, aluminum, wood, metal and fiberglass.

Aluminum is the least expensive at around $1,000 for two; vinyl is pricier at around $1,500. 


Your specific geographic area will also impact the installation costs and the amount of carpentry work required.  For example, the cost of purchasing and installing vinyl sliding doors in the Pacific Northwest is estimated to be $1,570, while the same project can be done in New England for about $1,650.


The cost of installation is lower if you are replacing an old door with a new one that is exactly the same size.  The costs rise if you require additional carpentry to install a door in a new location, or if an existing doorway requires modification.
