French Door Cost in 2026: Interior and Exterior Pricing
French door cost in 2026 ranges from $1,500 to $5,000 installed, depending on whether the doors are interior or exterior, the material, and the glass package. Exterior French doors with double-pane Low-E glass and a quality frame run $2,500 to $5,000. Interior French doors — which are simpler because they do not need weatherproofing — cost $1,500 to $3,000 per pair installed.
French Door Cost by Type
| French Door Type | Cost Per Pair (Installed) | Common Sizes | Best For |
|---|---|---|---|
| Interior (hollow core) | $800–$1,500 | 24″–36″ per door | Offices, dens, closets |
| Interior (solid core) | $1,500–$2,500 | 24″–36″ per door | Bedrooms, formal rooms |
| Interior (solid wood) | $2,000–$3,500 | 24″–36″ per door | High-end homes, period style |
| Exterior (fiberglass) | $2,000–$4,000 | 60″–72″ total width | Patio access, best value |
| Exterior (wood) | $3,000–$5,000 | 60″–72″ total width | Traditional homes, curb appeal |
| Exterior (steel frame/glass) | $2,500–$4,500 | 60″–72″ total width | Modern/industrial style |
The installed price includes the door pair, frame, hardware (handles and hinges), and labor. Exterior doors also include weatherstripping, threshold, and basic flashing. Custom sizes, sidelights, and transoms are extra — more on those below.
Interior French Door Cost Breakdown
Interior French doors split a wide doorway into two hinged panels, usually with glass panes from top to bottom. They let light pass between rooms while providing a visual and acoustic barrier. Here is what drives the cost:
| Component | Cost Range | Notes |
|---|---|---|
| Door pair (materials) | $400–$2,000 | Hollow core at low end, solid wood at high end |
| Hardware (hinges, handles, latch) | $50–$200 | Basic brass to premium oil-rubbed bronze |
| Frame/jamb | $50–$150 | Pre-hung doors include the frame |
| Installation labor | $200–$500 | Pre-hung takes 2–3 hours; slab-only takes 4–6 hours |
| Trim/casing | $50–$150 | Matching existing door trim in the room |
Pre-hung vs. slab. A pre-hung interior French door comes mounted in its frame, ready to drop into the rough opening. This is the right choice for 90% of homeowners — it is faster to install and ensures the doors are properly aligned. Slab-only doors (just the door panels without a frame) cost $100 to $300 less but require precise hinge mortising and frame building. Unless you or your carpenter have done this before, go pre-hung.
Glass Options for Interior French Doors
Most interior French doors have glass panels. The type of glass matters for privacy and sound:
Clear glass is standard and cheapest. Looks great for rooms that open to a shared space, but offers zero privacy.
Frosted or obscure glass adds $50 to $100 per door and provides privacy while still letting light through. Good for home offices and bedrooms.
Tempered glass is required by building code in most areas for any glass panel within 24 inches of the floor. It costs $30 to $60 more per panel but shatters into small pieces instead of dangerous shards if broken. Most pre-hung French doors come with tempered glass standard — check before buying.
Exterior French Door Cost Breakdown
Exterior French doors are a different animal. They must resist weather, provide security, and maintain a thermal barrier between your climate-controlled interior and the outside. This makes them more expensive and more complex to install than interior versions.
| Component | Cost Range | Notes |
|---|---|---|
| Door pair (materials) | $1,000–$3,000 | Fiberglass at low end, premium wood at high end |
| Glass (double-pane Low-E) | Included in door price | Triple-pane adds $200–$400 |
| Hardware (multipoint lock, handles) | $100–$400 | Multipoint locks recommended for security |
| Threshold & weatherstripping | $50–$150 | Adjustable threshold is standard |
| Installation labor | $400–$800 | Half day for replacement; full day for new opening |
| Flashing & waterproofing | $50–$150 | Critical for water management |
Material Choice for Exterior French Doors
Fiberglass is the best value for exterior French doors. It resists warping, does not rot, insulates well, and can be stained to look like wood. A fiberglass pair runs $2,000 to $4,000 installed and lasts 30 to 50 years with minimal maintenance. Most manufacturers offer realistic woodgrain textures that are hard to distinguish from real wood at arm’s length.
Wood looks the best but demands the most care. Exterior wood French doors need refinishing every 2 to 3 years and are prone to warping in humid climates. They cost $3,000 to $5,000 installed. Choose wood if your home’s architecture requires it — Victorian, Colonial, and Craftsman homes look wrong with fiberglass or steel doors.
Steel frame with glass panels gives a modern, industrial look at $2,500 to $4,500 installed. Steel is strong, secure, and thin-framed (which maximizes glass area). The downside is thermal conductivity — steel transfers cold rapidly, so it must have a thermal break in the frame to perform well in cold climates.
French Doors vs. Sliding Patio Doors
This is the most common decision for patio access. Here is how they compare:
| Factor | French Doors | Sliding Patio Door |
|---|---|---|
| Cost (installed) | $2,000–$5,000 | $1,200–$3,500 |
| Opening Width | Full opening (both doors swing) | Half opening (one panel slides) |
| Floor Space Needed | Swing arc requires clear floor area | None — panels stay in the wall plane |
| Energy Efficiency | Good — but two door seals = more potential gaps | Good — single track seal |
| Security | Better — multipoint locks, deadbolts | Weaker — bar locks, less rigid frame |
| Style | Traditional, elegant | Modern, minimalist |
| Accessibility | Step threshold can be a barrier | Flush track option available (ADA-friendly) |
French doors cost $500 to $1,500 more than sliding patio doors but provide a wider opening and stronger visual statement. Sliding doors work better in tight spaces where the swing arc of French doors would block furniture or foot traffic. If you have a deck or patio you use frequently, French doors create a better flow between indoor and outdoor space.
Add-Ons and Upgrades
Sidelights
Sidelights are narrow glass panels flanking the French doors. They add width and light without adding another operable door. A pair of sidelights adds $400 to $1,000 to the project and requires a wider rough opening. They look great on entry door installations and formal patio exits.
Transoms
A transom is a glass panel above the doors. It adds height and light, especially in rooms with tall ceilings. Fixed transoms cost $200 to $500. Operable transoms (that open for ventilation) cost $400 to $800. Transoms do not require structural changes if the rough opening is already tall enough.
Built-In Blinds
Blinds sealed between the glass panes eliminate the need for curtains and stay clean. They add $150 to $300 per door. The trade-off: if the blind mechanism breaks, the entire glass unit must be replaced. External blinds or curtains are cheaper and easier to repair.
Screen Doors
French door screen options include retractable screens ($200 to $500), hinged screen doors ($150 to $400), and magnetic screen curtains ($30 to $60). Retractable screens are the most popular because they disappear when not in use. Budget for screens when planning your project — French doors without screens are impractical in any region with bugs.
Installation Considerations
Replacing an existing patio door. If you are swapping a sliding patio door for French doors, the rough opening is usually the right width already. A contractor adjusts the frame and installs the new doors in half a day. Cost: $2,000 to $4,500 including the doors.
New opening in an exterior wall. Cutting a new opening requires structural work — a header to carry the load above, jack studs, and potentially relocating electrical or plumbing. Add $1,000 to $3,000 for structural work on top of the door cost. A building permit is required.
Interior French door installation is simpler. If you are replacing an existing single door, you may need to widen the opening — which involves cutting drywall, adding framing, and patching. If the opening already exists (like a cased opening or archway), the install is straightforward.
Proper waterproofing on exterior French doors is critical. The threshold must slope outward, the flashing must overlap correctly (shingle style, from bottom up), and the sill pan under the threshold must drain to the exterior. Water intrusion at French doors is one of the most common causes of subfloor rot in homes. Make sure your installer gets this right. Our home service providers can help you find qualified contractors.
French Door ROI
Exterior French doors return 50% to 70% of cost at resale, which puts them in the middle range of renovation ROI. The return is higher when the doors open to a usable outdoor space — a deck, patio, or garden. Buyers respond to the indoor-outdoor connection, especially in warmer climates and homes with entertaining spaces.
Interior French doors do not show up in ROI data directly, but they add perceived value. Rooms with French doors photograph better in listings, feel more finished, and signal quality to buyers. If you are selling, interior French doors on a home office or den are a low-cost upgrade with outsized visual impact.
Financing French Doors
An exterior French door project at $2,500 to $5,000 is within reach of most homeowners through several financing options. A HELOC offers the lowest rates because it is secured by your home. Personal loans work if you do not want to use home equity. Some door manufacturers offer promotional 0% financing for 12 to 24 months on larger orders. See our full financing guide for details on loans, credits, and rebates — exterior doors qualify for up to $250 per door ($500 total) in federal energy efficiency tax credits if they are ENERGY STAR certified.
Frequently Asked Questions
How much do French doors cost compared to sliding doors?
French doors cost $2,000 to $5,000 installed versus $1,200 to $3,500 for sliding patio doors. The premium is $500 to $1,500, driven by more hardware, more complex installation, and stronger security features.
Are exterior French doors energy-efficient?
With double-pane Low-E glass and proper weatherstripping, modern French doors are reasonably efficient. They are not as tight as a solid wall, but quality units with multipoint locks compress the weatherstripping evenly for a good seal. The biggest efficiency risk is the threshold — make sure it has an adjustable seal.
Can I install French doors myself?
Interior pre-hung French doors are a manageable DIY project for experienced homeowners — expect 4 to 6 hours. Exterior French doors are harder because of the weatherproofing, flashing, and threshold work. A mistake on an exterior door leads to water intrusion, which causes expensive damage. Most homeowners are better off hiring a pro for exterior installations.
Do French doors need a center post (astragal)?
Most exterior French doors have an astragal — a vertical strip on the inactive door that the active door closes against. It provides weather sealing and a locking point. Some premium models have a hidden astragal or no astragal for a clean, unobstructed opening. Astragal-free designs cost $200 to $500 more.
How wide of an opening do French doors need?
Standard exterior French doors fit a 60-inch to 72-inch wide rough opening. Interior French doors fit openings from 48 inches to 72 inches. If your opening is narrower, you can use a single French door (one hinged glass panel) instead of a pair, which costs $800 to $2,000 installed.
Are French doors secure?
Modern exterior French doors with multipoint locking systems are reasonably secure. The lock engages at three or more points along the door edge (top, middle, bottom), which makes the door much harder to force open than a single-point deadbolt. Add a quality deadbolt to the inactive door and keep the astragal flush bolts engaged when the door is locked.
