Estimate French door installation cost — with the free door calculator.
French doors bring light, air and a touch of class to any room. The unit is half the story — the installation is where costs vary. Here's the real 2026 cost.
THE SHORT ANSWER
The short answer
French door installation runs $1,100–$3,800 per set in 2026 (Homewyse: $1,712–$2,617 per door). Labor runs $300–$800 per door. The unit runs $500–$2,000+. Replacing an existing door opening costs less than cutting a new one.
What it costs
A French door unit runs $500–$2,000+. Installation labor runs $300–$800 per door. Total installed runs $1,100–$3,800 per set. Cutting a new opening adds $1,000–$3,000 for framing, header and siding work.
- Unit: $500–$2,000+
- Labor: $300–$800 per door
- Total per set: $1,100–$3,800
- New opening (framing): $1,000–$3,000
Replace vs new opening
Replacing an existing door or window opening is the cheap path — same rough opening, minimal framing. Cutting a new opening means framing, a header and exterior work. In a load-bearing wall, that's an engineer's call and $2,000+ extra.
