Replacing a garage door with French doors typically costs $4,000-$12,000 for a standard opening, with a national midpoint near $7,500. The price depends on door size and quality, framing and exterior finish work, structural changes, local labor rates, and permit requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete conversion | $4,000 | $7,500 | $12,000 | Standard 16-foot-wide opening; ordinary access |
| French door unit | $1,200 | $2,800 | $5,500 | Pair of exterior doors, before installation |
| Installed conversion rate | $250 | $470 | $750 | Per linear foot of a 16-foot opening |
Typical price for a 16-foot garage opening
A basic conversion usually costs $4,000-$6,000 when the opening can be reduced with standard framing, the French door unit is entry-level, and siding or trim is easy to match. Midrange work is commonly $6,000-$9,000, while custom doors, extensive exterior repairs, or structural complications can push a project to $12,000-$15,000 or more.
A realistic planning allowance for a standard two-car opening is about $7,500. This assumes a roughly 16-by-7-foot opening, a prehung exterior French door around 60-72 inches wide, wood or vinyl framing, standard hardware, and no major foundation or electrical work. A single-car opening may cost less, but the reduction is not proportional because permits, setup, and finish work remain.
Assumptions: U.S. national pricing, standard materials, ordinary access, and no major structural damage.
What framing, doors, and finish work add to the quote
The existing garage-door opening is much wider than most French door units. Contractors typically remove the overhead door and tracks, build a framed infill wall, install and flash the door, then blend the inside and outside finishes. The estimate should identify whether disposal, insulation, siding, and interior drywall are included.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| French door unit | $1,200 | $2,800 | $5,500 | Exterior-rated pair, frame, basic hardware |
| Removal and disposal | $200 | $450 | $900 | Door, tracks, opener, and debris |
| Framing and installation labor | $1,200 | $2,400 | $4,000 | Infill, header adjustments if needed, door setting |
| Exterior and interior finishes | $700 | $1,500 | $3,200 | Siding, trim, drywall, insulation, paint |
| Permit and inspection | $100 | $350 | $900 | Varies by jurisdiction and review needs |
Door, framing, and finish work account for most of the project total. Custom color matching, new flooring at the former garage threshold, and replacement of damaged framing can add several hundred to several thousand dollars.
How opening width, door material, and structure change price
Most French door pairs are about 5-6 feet wide, so a 16-foot garage opening requires substantial infill; a 9-foot single-car opening still needs a framed wall around the narrower unit. A wider 72-inch pair generally costs more than a 60-inch unit, and outswing doors may need extra clearance on a driveway or patio.
Fiberglass and vinyl units often cost less than custom wood or steel-and-glass designs. Expect roughly $1,200-$3,000 for common stock units, $2,500-$5,500 for higher-grade or custom units, and additional charges for impact-rated glass or unusual dimensions. A load-bearing header change, rot, or a sloped or cracked threshold can add $500-$3,000 or more.
Every extra foot of opening width can mean more infill framing and exterior finish work. Confirm whether the existing header remains adequate and whether the contractor has included insulation and weatherproofing behind the new wall.
Control the conversion cost with scope and material choices
Keep the project close to the $4,000-$7,000 range by choosing a standard-size, prehung exterior door and limiting finish changes to the immediate opening. Reuse matching siding or trim where practical, but do not omit flashing, insulation, or appropriate exterior sealing to save a small amount upfront.
Ask for separate prices for the door, demolition, framing, finish work, and permit. Compare at least three itemized quotes with the same door specifications and finish scope. If the opening needs extensive structural work, ask whether a smaller framed opening or a standard single exterior door would meet the use case for less.
Scope control and comparable quotes are the clearest ways to avoid paying for upgrades the opening does not need. Verify that estimates include removal of the old opener and tracks, debris disposal, and any required interior patching.
How long the French door installation takes
A straightforward conversion often takes a crew of two or three about 1-3 working days after materials arrive. Demolition, framing, and setting the door may take 8-16 labor hours; exterior cladding, drywall, paint, or concrete threshold work can extend the schedule. Weather can delay exposed exterior work, especially if the opening cannot be closed the same day.
Labor commonly runs $50-$100 per hour per worker, though contractors often quote a combined project price. For example, 24-40 worker-hours at $65-$85 per hour represents roughly $1,560-$3,400 in labor before material and permit charges.
Ask whether the quote includes temporary weather protection and final cleanup. Those details matter if the old door is removed before the replacement wall and doors are ready.
Permits and code checks for changing a garage opening
Many jurisdictions require a building permit when a garage-door opening is altered or converted into an exterior door. Permit fees may be $100-$900, with higher charges possible when plans or structural review are required. Local rules can also govern emergency egress, safety glazing, energy insulation, landing dimensions, and the separation between a garage and living space.
Garage-to-house fire-separation requirements may apply if the new doors connect the garage directly to the home. Exterior French doors facing outdoors are a different situation, but the revised wall still may need inspection. The local building department can confirm requirements before work begins.
Confirm permit responsibility in writing before accepting a low bid. A quote that excludes permit fees or required code upgrades may not reflect the final project price.
Why French door conversion prices differ by region
Labor and permit costs can vary substantially across the United States. In lower-cost rural markets, a standard conversion may fall near the low end of the national range; dense metropolitan areas and high-cost coastal markets can run 15%-30% higher because of labor, disposal, and compliance costs. Remote locations may also pay more for delivery or specialist availability.
These are broad comparisons, not fixed regional rates. Door availability, local siding types, and the amount of finish carpentry can matter as much as location. Requesting quotes from contractors who regularly handle exterior framing helps separate a normal regional premium from an unusually broad estimate.
Compare local quotes by scope rather than by the total alone. A higher bid may include permit handling, insulation, siding repair, and interior finishing that another contractor left out.
Three sample quotes for different conversion scopes
| Scenario | Door and scope | Labor assumption | Estimated total |
|---|---|---|---|
| Basic single-car | 9-foot opening; stock vinyl pair and simple infill | 20-28 worker-hours at $55-$75 per hour | $3,800-$6,000 |
| Typical two-car | 16-foot opening; midrange fiberglass pair, siding and drywall patch | 30-42 worker-hours at $65-$85 per hour | $6,000-$9,500 |
| Custom finish | 16-foot opening; custom wood doors, upgraded glass and siding match | 40-56 worker-hours at $80-$105 per hour | $10,000-$15,000 |
These examples include typical materials, labor, removal, and routine finishing, but not major structural repairs. Local permit fees and taxes can shift totals, and custom orders may require a deposit or longer lead time.
