What a standard slider costs

Five guides price the common 6 foot, two-panel door. The calculator takes the middle of their lows, highs and averages.

Guide	Range	Average
Fixr	$2,000 to $4,000	$2,756
HomeAdvisor	$1,169 to $4,143	$2,564
Bob Vila	$1,550 to $6,250	$2,500
This Old House	$600 to $10,000	$2,500
Today's Homeowner	$1,000 to $7,500	Not given

Panels, frames and glass

More panels mean more glass, frame and weight. This Old House lists the door alone at $400 to $1,500 for two panels, $1,500 to $3,500 for three and $2,500 to $5,500 for four.

Frame	HomeAdvisor	Bob Vila
Vinyl	$300 to $1,200	$300 to $1,200
Aluminum	$750 to $2,500	$600 to $2,000
Fiberglass	$1,500 to $2,500	$800 to $3,500
Wood	$1,000 to $3,000	$1,500 to $5,000

Glass upgrades matter too. This Old House puts Low-E coating at $100 to $500 and hurricane glass at $1,000 to $3,000; Today's Homeowner says $1,000 to $3,100 for impact glass. The calculator adds the middle of the two.

Same opening or a new one

A like-for-like swap is usually a day's work. Putting a slider where there was a window or a smaller door means cutting the wall, adding a header and finishing inside and out, which HomeAdvisor puts at $1,000 to $3,600. A bearing wall may need an engineer.

A worked example

A standard two-panel slider in the same opening, at the US average: $1,150 to $6,250, about $2,550 typical. Make it a three-panel door in a new opening and the typical becomes $5,850. Enter a ZIP to scale the 45% labor share to your state.

Quoting patio doors

Quote the door model by name. Brand and glass package explain the price.
Line out the opening work. Header, framing and trim are separate from the door.
Mention the screen. Some doors include it, some do not.

Turn the result into an estimate in Koira, take a deposit, and order the door when it is approved.
