Installing French doors in an exterior wall typically costs $2,500-$7,500 when the project includes a new opening, standard doors, framing, and weatherproofing. The cost to install French doors in an exterior wall depends most on whether an opening already exists, wall structure, door size and material, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New exterior opening and doors | $2,500 | $5,000 | $10,000+ | Standard-size pair; structural work can raise the total |
| Replacement in existing opening | $1,200 | $2,500 | $4,500 | Assumes little or no reframing |
| Door unit | $600 | $1,600 | $4,000+ | Fiberglass, steel, or wood; before installation |
| Installed price per opening | $2,500 | $5,000 | $10,000+ | Includes typical carpentry and finish work |
What a new exterior French door opening usually costs
For a new opening in an exterior wall, homeowners commonly pay $2,500-$7,500 for a straightforward project using a standard 60- to 72-inch-wide door unit. A national midpoint is about $5,000, though higher-cost metro areas, custom sizes, and structural changes can push quotes beyond $10,000. This estimate generally covers the doors, cutting and framing the opening, setting the unit, flashing, and basic interior and exterior trim.
A new opening costs substantially more than swapping doors into an existing, correctly sized opening. A basic replacement may run $1,200-$4,500, while a new opening requires demolition, structural support, and wall finish repairs. The estimate also assumes ordinary access, no hazardous materials, and no major electrical, plumbing, or HVAC lines in the wall.
For a standard 5- to 6-foot-wide opening, the door unit may cost $600-$2,500 for common steel or fiberglass models; wood and premium glass options can exceed $4,000. Installation labor and framing commonly add $1,000-$3,500, with trim, flashing, disposal, and permits adding another $300-$1,500 depending on scope and location.
Assumptions: Standard 60- to 72-inch opening, midgrade doors, ordinary access, and typical U.S. contractor pricing.
How door, framing, labor, and finish work shape the quote
Contractors may combine tasks into one bid, so the table gives approximate components rather than guaranteed separate charges. Structural engineering, extensive siding replacement, or interior finish repairs can fall outside a basic installation quote. Ask whether each line includes both materials and installation, especially framing, flashing, and trim.
| Cost component | Typical range | What it covers | Pricing basis |
|---|---|---|---|
| French door unit | $600-$4,000+ | Two hinged panels, frame, glass, and hardware | Per unit |
| Carpentry and installation labor | $900-$2,800 | Cutting, framing, setting, shimming, and fastening | $75-$125 per hour; often 12-24 hours |
| Header and structural framing | $400-$1,800 | Header, king studs, jacks, and load transfer | Per opening; engineering may be extra |
| Flashing, insulation, and sealants | $150-$600 | Water management and air sealing | Per opening |
| Trim and finish repairs | $250-$1,200 | Casing, drywall, siding, paint, or stain touch-ups | Per opening; broad patching costs more |
| Permit and debris disposal | $100-$700 | Local permit fees and removal of construction waste | Per project |
Example: 16 labor hours at $95 per hour equals $1,520 before materials, permits, or specialty trades.
Wall structure and door width can shift the total
The wall type and opening dimensions are major quote variables. A non-load-bearing partition is less complex, but exterior walls usually carry roof or floor loads and must be framed to transfer those loads around the new opening. A 60-inch pair typically needs less extensive framing than a 72- or 96-inch unit, and custom widths may require more labor or a made-to-order door.
Load-bearing work and wider openings commonly add hundreds or thousands of dollars. A standard header installation may add $400-$1,800. If the opening is wider than about 6 feet, the contractor may need a larger engineered header or additional posts; engineered lumber and installation can add $800-$2,500 or more. A structural engineer’s visit and calculations may cost $300-$1,000 when required by the project or building department.
Wall construction changes labor, too. Wood framing is usually more straightforward to cut and rebuild than brick, stone, or concrete. Masonry cutting and patching can add $1,000-$4,000, depending on wall thickness, access, lintel requirements, and finish matching. If the wall contains wiring, plumbing, or a heating line, rerouting it may add $300-$2,000 per affected trade.
Door specifications matter beyond width. Tempered or impact-rated glass, between-the-glass blinds, upgraded locks, and energy-efficient glazing raise the unit price. A basic fiberglass unit may cost $800-$2,000, while a custom wood or impact-rated pair may cost $2,500-$5,000 or more before labor.
How many labor hours does wall installation take
A straightforward new opening often takes a two-person crew 1-3 days on site, or roughly 12-24 combined labor hours, excluding delays for inspections or finish curing. Replacement in an existing opening may take 6-12 labor hours if the frame is sound. Projects involving masonry, heavy doors, complex trim, or structural engineering can take several days longer.
Labor is often the largest variable after the door unit itself. Typical carpenter or installer rates are about $75-$125 per hour, while specialized masonry or structural work may bill at $90-$150 per hour. Some contractors quote a fixed project price instead of hourly billing, but the hours still help compare bids with different scopes.
Preparation and finishing can require separate visits. A crew may install the door and weather barrier first, then return for trim, siding, drywall, or paint. Confirm whether the quote includes painting and finish matching; otherwise, a painter may charge $200-$800, and siding repair can cost more if the existing profile or color is difficult to match.
Existing opening replacement versus cutting a new wall opening
Replacing an existing exterior French door in a sound opening commonly costs $1,200-$4,500, including a standard door unit and installation. If the opening is already the right size and the sill, jamb, and surrounding wall are dry and intact, the project may avoid major framing and finish repairs. New hardware or a basic threshold may be included, but verify the quote.
Changing the opening size usually removes much of the savings of a simple replacement. Widening or raising an opening can bring the total to $2,500-$7,500 or more because the contractor must alter framing, siding, drywall, and possibly the header. A smaller door in an oversized opening also needs infill framing and finish work, which can cost $500-$2,000.
Repair can be cheaper than full replacement when only one component has failed. Replacing a lockset may cost $100-$350 installed, while repairing a sticking panel or adjusting hinges may cost $150-$500. However, persistent water damage, soft framing, fogged insulated glass, or a warped frame can make replacement more practical. Ask the contractor to price both a targeted repair and a full unit replacement when the condition is uncertain.
Regional labor rates and permit rules affect French door prices
Labor and permit costs vary by market. Quotes in high-cost coastal cities and large metro areas may be 15%-35% above a national midpoint, while rural areas may come in 5%-20% below it. These differences are not guaranteed: limited contractor availability, travel distance, local material prices, and the need for a specialty crew can outweigh broad regional patterns.
Compare local bids using the same door size and written scope, not a national average alone. A $5,000 estimate may be competitive in a high-cost market and expensive in a lower-cost area. Obtain at least two or three itemized quotes and check whether each includes delivery, disposal, flashing, interior trim, exterior repairs, permit handling, and sales tax where applicable.
Many jurisdictions require a building permit when a new exterior opening changes structural framing or the building envelope. Permit fees commonly range from $100-$500, but some locations base fees on project value or require plan review. Code requirements may cover tempered safety glass near doors, emergency egress, energy performance, and wind resistance. The contractor should identify applicable inspections and clarify who schedules them.
Older homes may require testing or extra precautions if demolition could disturb lead paint or asbestos-containing materials. Testing may cost $200-$800; regulated abatement can add much more. Do not assume these charges are included in a standard door quote. Get written confirmation before work begins if the home’s age or materials raise concern.
Flashing, removal, and finish repairs add to the installed price
Door installation is not complete when the unit is simply fastened in place. Proper sill pan, flashing, insulation, and sealant help prevent drafts and water intrusion. Basic materials may add $150-$600, while repairing rot or water damage around the sill can add $300-$2,000 or more, depending on how far the damage extends beneath siding or flooring.
Waterproofing and sound framing are more valuable than cosmetic upgrades that do not address leaks. Removing an old door and hauling it away may cost $100-$400 if not included. Replacing damaged siding, patching drywall, and refinishing trim can add $250-$1,200; broad exterior matching or interior repainting may exceed that range.
Delivery charges are often included for a locally stocked unit but may add $75-$300 for a special-order door or long-distance delivery. Rush orders, difficult stairs, or limited job-site access can trigger additional charges. Ask whether a contractor’s minimum service fee applies if a small repair is quoted separately, and request any expected change-order rates before signing.
Which choices can lower the French door installation bill
Keeping the existing opening dimensions is usually the most effective way to control cost. If the current frame is structurally sound and correctly sized, replacing only the door unit can avoid new framing and some wall repairs. Select a standard 60- or 72-inch size and a commonly stocked fiberglass or steel model to reduce custom fabrication and delivery expenses.
Keep the project scope clear, but do not cut out essential structural or water-control work. Before requesting bids, decide whether the project includes paint, trim replacement, siding repair, disposal, and hardware upgrades. Ask contractors to separate required work from optional improvements so estimates can be compared on an equivalent basis.
Homeowners can sometimes save by moving furniture, clearing access, and handling minor site preparation, but should not remove exterior trim or cut the wall before a contractor confirms the framing plan. Unplanned demolition can expose wiring, rot, or structural issues and increase the final bill. Bundling the door installation with nearby siding or window work may reduce mobilization costs if the same crew can perform both jobs.
Compare at least three written quotes and check the door model, glazing, warranty, labor scope, permit responsibility, and payment schedule. A low bid that omits flashing, disposal, or finish repairs may not be the least expensive completed project. For a clear comparison, ask each contractor to price the same door, opening size, and finish standard.
