French door installation in Los Angeles typically costs between $2,000 and $8,000 per set installed, depending on interior versus exterior, material, and whether a new opening is required. A 2026 guide:
| Item | Typical Cost |
| Interior French doors | $1,500 to $3,500 installed. |
| Exterior French doors (replacing existing) | $3,000 to $6,000. |
| Exterior French doors in a new opening | $5,000 to $8,000+, including framing, header, and weatherproofing. |
