How This Calculator Works
This french door installation cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your French Door Installation Cost
Interior vs. Exterior Installation
$500 - $2,000Interior French doors cost $500-$1,500 less than exterior ones because they don't need weatherproofing, insulated glass, or multi-point locks. Exterior doors require flashing, thresholds, and weather-rated components.
New Opening vs. Replacement
$0 - $2,000Swapping an existing double door or sliding door is simpler. Creating a new opening in a wall requires framing a header, which costs $800-$2,000 depending on whether the wall is load-bearing.
Door Material
$400 - $3,000Steel French doors start at $400-$800 per pair. Fiberglass runs $800-$1,800. Solid wood doors range from $1,500-$4,000+, with mahogany and custom stain options at the top end.
Glass Options
$100 - $800Standard clear dual-pane glass is included. Simulated divided lites add $100-$200. Low-E and argon fill add $150-$300. Triple-pane glass adds $300-$800. Decorative or frosted glass adds $200-$500.
Hardware & Locking Systems
$75 - $500Basic lever handles run $75-$150. Decorative hardware sets cost $200-$350. Multi-point locking systems for exterior doors add $150-$500 and significantly improve security and weathersealing.
