French Doors Cost: $600–$5,500 (Average $3,500) in 2026

Why do French doors cost so much?

French doors cost more than a standard single door because you’re paying for two matched door panels, more glass, and often more complex framing and hardware. A fully installed project typically lands between $600 and $5,500, averaging around $3,500 nationally (Angi, HomeGuide). Where you’re putting them matters a lot: interior French doors, which don’t need to be weatherproofed or handle structural loads, run $400 to $3,000, while exterior sets jump to $1,000 to $5,500 once you factor in insulated glass, weatherstripping, and locking hardware built for the outdoors (Angi, HomeGuide). Door configuration adds another layer of variation — a simple single in-swing door can cost as little as $300 to $1,000, while a telescoping sliding pair runs $1,500 to $6,000 (Angi). Labor typically adds $300 to $500 as a flat fee, or $70 to $120 per hour across a two-to-five-hour job (Angi, HomeGuide).

What affects the cost?

A few factors explain most of the spread between a $600 interior swap and a $5,500-plus exterior install:

• Interior vs. exterior placement. Exterior sets run $1,000 to $5,500 installed versus $400 to $3,000 for interior doors, since exterior units need better insulation, weatherstripping, and security hardware (Angi, HomeGuide).
• Door material. Vinyl and wood tend to be the cheapest options, while fiberglass and clad-wood doors cost more — clad-wood alone can run $2,500 to $5,500 for the door (Angi).
• Door configuration. Single in-swing doors start around $300 to $1,000, double hinged or sliding doors run $400 to $4,000, and telescoping sliders can reach $1,500 to $6,000 (Angi).
• New opening vs. replacement. Swapping doors into an existing opening is cheaper than cutting or enlarging one; replacements typically run $490 to $1,392, while new-opening projects can approach $2,987 (Thumbtack).
• Glass type. Basic single-pane or tempered glass costs less than double- or triple-pane glass, which can add several hundred to a couple thousand dollars (Angi, HomeGuide).
• Custom sizing. Non-standard dimensions or premium hardware push custom projects to $3,000 to $10,000 per Angi, or up to $15,000 per HomeGuide.

How to lower your French doors cost

• Stick with a standard size and configuration. Custom French doors cost $3,000 to $10,000 per Angi, or up to $15,000 per HomeGuide, well above the $600 to $5,500 range for standard sizes, so off-the-shelf dimensions save the most.
• Reuse the existing opening. Replacing doors in place typically costs $490 to $1,392, far less than framing a new or enlarged opening, which can run closer to $2,987 (Thumbtack).
• Choose vinyl or wood over fiberglass or clad-wood. These materials are consistently priced lower across sources while still holding up well for many climates (Angi, HomeGuide).
• Compare in-swing against sliding or telescoping options. A basic single in-swing door starts as low as $300 to $1,000, well under the $1,500-to-$6,000 range for telescoping sliders, if swing clearance isn’t an issue (Angi).
• Get a flat-rate labor quote when possible. Flat fees of $300 to $500 can work out cheaper than hourly rates of $70 to $120 on jobs that run long due to site conditions (Angi, HomeGuide).

Prices vary by region, door material, and whether you’re doing a straight swap or a new opening, so treat the figures above as a planning budget. Get two or three local quotes and confirm whether framing, glass upgrades, and hardware are included before comparing bids.
