Average Installing French Doors Cost in 2025

For construction professionals, staying updated with current pricing is essential. The average cost for a single patio-size French door installation is between $2,900 and $5,800. Factors such as premium wood species or impact-rated glazing can elevate costs to $7,500–$11,000.

Key Cost Drivers

  • Door unit price: Steel and fiberglass units start near $1,100, while custom mahogany can top $4,000.
  • Rough opening modifications: Enlarging or moving an opening adds carpentry and structural header work.
  • Hardware and security packages: Multi-point locks, smart handles, and matte black finishes may add $250–$750.
  • Energy or impact ratings: Low-E, argon-filled IGUs and coastal codes influence glass and frame cost.
