How to Estimate Patio Door Installation
Contractor method to estimate patio door installation by door type, width, removal and labor with clear materials and labor lines.
A patio door is priced by the unit, its width, and how much of the old door and frame you are removing. The rough opening and the threshold are where installation time really shows. This guide covers choosing the door, sizing the opening, and quoting the removal and prep.
THE SHORT ANSWER
How to Estimate Patio Door Installation
A sliding door 6 ft wide with 8 labor hours at $75 totals about $2,400.
Choose the door type and size
Sliding and hinged (French) patio doors price differently, and wider units cost more and are heavier to set. Match the door to the opening and the traffic.
- Door type
- Width
- Remove old door
- Labor hours
Check the rough opening
The rough opening has to be plumb, level and square. If it is not, the quote needs shimming and possible framing repair before the door goes in.
Threshold and flashing are essential
The threshold carries water to the exterior, and flashing behind it stops leaks. Confirm these are in the scope, not an extra.
Compare patio door installs
Ask for a quote that separates the door, the removal of the old unit, and the prep and labor. Confirm who handles the old door disposal.
