Interior French Door Opening, Header, and Privacy Audit

Interior French doors add light and separation, but the quote should define the opening, pair size, header or framing changes, glass type, privacy level, hardware, casing, paint, and floor transition work.

Scope checks

  • 1Confirm rough opening width/height, door pair size, slab vs pre-hung set, astragal, latch type, active/inactive leaf, glass style, privacy film or frosted glass, and hardware finish.
  • 2Ask whether wall opening enlargement, header changes, electrical relocation, trim/casing, drywall patching, flooring transition, and paint are included.
  • 3For home offices and bedrooms, compare glass privacy and acoustic performance before choosing clear glass because French doors trade privacy for light.

Quote traps

  • Door-set pricing that excludes framing, drywall, casing, paint, flooring repair, or electrical relocation.
  • No plan for out-of-square openings, uneven floors, door sweep clearance, or latch alignment across two active panels.
  • Choosing clear glass for a room that needs privacy, sound reduction, or video-call separation.

Proof to collect

  • Door pair dimensions, glass type, jamb/casing detail, swing direction, hardware, and finish scope in the bid.
  • Photos before closure if framing or electrical changes are made.
  • Final check of reveal gaps, latch, astragal, door stops, swing clearance, and privacy expectations.

What Affects the Price

  • 1Door size (standard vs custom)
  • 2Glass panel style
  • 3Material (wood, fiberglass)
  • 4Hardware quality
  • 5Header modification

Popular Upgrades

  • Frosted glass panels
  • Barn door track alternative
  • Black matte hardware

Discuss upgrades with your contractor before finalizing the quote. Some upgrades are cheaper to include during initial construction than to add later.
