French door installation adds a classic, elegant entry point to patios, decks, or between interior rooms. Exterior French doors feature tempered dual-pane Low-E glass, multi-point locking systems, and weatherproof thresholds. Interior French doors can include clear, frosted, or decorative glass panels. The installation involves removing the existing door or window, framing the opening to the correct width (typically 5 or 6 feet for a double door), installing the pre-hung frame, and finishing with hardware, trim, and weatherstripping. French doors swing open fully, offering wider access than sliding doors.

French Door Installation en South San Francisco — Preguntas Frecuentes

How much do French doors cost installed?+

Exterior French door installation in NorCal runs $1,800-$4,500 for vinyl or fiberglass and $3,500-$7,500 for wood or clad-wood. Interior French doors cost $800-$2,500 installed, depending on glass type and hardware.

Are French doors energy efficient?+

Modern exterior French doors with dual-pane Low-E glass, multi-point locks, and proper weatherstripping meet Title 24 energy requirements. They are slightly less efficient than sliding doors due to the center astragal, but proper installation and quality weatherstripping minimize air infiltration.

French doors vs. sliding doors — which is better?+

French doors offer wider full-opening access and a more traditional aesthetic. Sliding doors save space (no swing clearance needed) and have fewer air leak points. The choice depends on your style preference, available space, and budget.

Can I replace a sliding door with French doors?+

Yes, if the rough opening width matches. French doors require 3-4 feet of swing clearance on one side. If you have furniture or foot traffic near the opening, consider outswing French doors.

Do French doors need a center post?+

Most French doors have an astragal (center post) on one door panel that the other door latches to. Some high-end models offer a removable astragal for a completely open doorway.
