Typical Cost Snapshot
For a typical french door installation scenario in the national baseline, this calculator currently models a total around $3,864, or about $3,864 per door.
This market is currently modeled close to the national baseline, so project swings are more likely to come from scope and finish choices than from regional pricing alone.
Local labor conditions, permit timing, and finish selection all influence how this project prices in your market.
Low / Mid / High Project Scenarios
| Scenario | Total | What it covers |
|---|---|---|
| Low | $1,569$1,569 per door | Single interior French door pair with standard glass, existing opening, basic hardware, and light casing touch-up. |
| Mid | $3,866$3,866 per door | Single exterior fiberglass French door pair with Low-E glass, jamb adjustment, standard lockset, trim, and old-door removal. |
| High | $22,117$11,058 per door | Two impact-rated exterior French door openings with divided-lite impact glass, widened openings, multipoint hardware, and custom finish work. |
What Changes the Estimate Most?
- Interior vs exterior French doors is the first major cost split because exterior units require thresholds, sealing, flashing, and weatherproofing.
- Glass package multiplies the unit cost quickly, especially for divided-lite, Low-E, and impact-rated door pairs.
- Opening work is the biggest labor swing: replacing an existing unit is straightforward, while widening a wall or converting a window can add structural framing.
When This Calculator Is Less Accurate
This calculator is less accurate when the project includes structural beam engineering, water-damaged exterior framing, masonry/stucco opening rebuilds, historic custom millwork, or hurricane-rated assemblies with local product-approval requirements beyond a standard residential French-door install.
Use the result as a budgeting starting point, then validate with local contractor quotes if the scope includes specialty materials, hidden damage, or permit-driven design changes.
How Much Does French Door Installation Cost?
French door installation typically costs $1,200-4,500 for an interior or standard exterior replacement and $5,000-10,000+ for impact-rated exterior doors, widened openings, or wall-to-door conversions. Door material, glass package, structural opening work, and weatherproofing details drive most of the spread.
Cost Factors:
- Interior French doors are much cheaper than exterior prehung pairs because they do not need thresholds, sill pans, weatherstripping, or exterior flashing
- Low-E, decorative divided-lite, and impact glass add cost because the upgrade multiplies the door unit price
- Existing openings keep costs predictable; widening an opening or converting a wall/window to doors adds framing, header, and finish work
- Multipoint locks, flush bolts, premium hinges, and security hardware add per-opening cost
- Exterior trim, sill pans, flashing, paint, and flooring transitions can make finish work a major line item
Frequently Asked Questions (3)
How much does French door installation cost?
Interior French doors often cost $1,200-2,800 installed. Standard exterior French doors commonly run $2,500-5,500 installed, while impact-rated or widened-opening projects can reach $7,000-12,000+.
Are exterior French doors more expensive than sliding doors?
Often yes for the same opening size, especially when the French doors use multipoint hardware, divided-lite glass, or impact-rated panels. Sliding doors usually cost less for wide openings, while French doors offer a more traditional look.
Do French doors need structural work?
Not if the new prehung unit fits the existing rough opening. Structural work becomes likely when widening an opening, converting a window to doors, or installing doors where there was previously a solid wall.
