Labor to install a prehung exterior door typically costs $300-$800, with many standard replacements near $500 before materials. The final price depends on door size and weight, frame condition, removal and disposal, and whether the opening needs repairs or code-related upgrades.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor only | $300 | $500 | $800 | Standard replacement opening |
| Door unit | $250 | $650 | $1,800 | Fiberglass, steel, or premium wood |
| Full installation | $650 | $1,250 | $2,800 | Door, labor, and common supplies |
| Labor rate | $50/hr | $85/hr | $125/hr | Per installer, local rates vary |
Typical labor price for a standard prehung exterior door
For a like-for-like replacement in a sound, standard-size opening, a contractor commonly charges $300-$600 for labor. A larger or heavier door, difficult access, or extra framing work can raise labor to $600-$1,000 or more. These figures generally cover setting, shimming, fastening, insulating, and checking the door swing and lock alignment.
A prehung exterior door includes a door slab attached to its frame, so the installer fits the complete unit rather than hanging a slab in an existing jamb. Materials are separate from labor unless the quote says otherwise. For a straightforward replacement, budget about $500 for labor and $900-$1,600 for the installed project.
Assumptions: U.S. suburban labor rates, one standard 36-by-80-inch door, normal access, and no structural repairs.
What removal, framing, and finishing add to the quote
Labor estimates often combine several tasks. Ask whether the price includes taking out the existing door, preparing the opening, installing the new unit, and finishing the interior and exterior edges. The table shows common labor allowances; actual bids may bundle tasks rather than list them separately.
| Labor task | Typical price | What changes the charge | Common time |
|---|---|---|---|
| Remove old unit | $75-$200 | Rot, layered trim, or difficult fasteners | 1-2 hours |
| Set and secure new unit | $200-$450 | Door weight and opening accuracy | 2-4 hours |
| Repair framing or sill | $100-$500 | Extent of rot or water damage | 1-4 hours |
| Trim and seal | $75-$250 | Trim style and finish scope | 1-3 hours |
Hardware installation may be included, but repainting, staining, new casing, and extensive siding repair are often extra. Labor pricing can also include a minimum service charge when the door is part of a small job. Confirm the exact finish and disposal work before comparing totals.
Door width, wall damage, and threshold height change labor
Standard 32- or 36-inch doors usually fit familiar rough openings. A door wider than 36 inches, a double-door unit, or a tall custom unit may need two installers and more careful handling, adding roughly $150-$500 in labor. Masonry openings and narrow hallways can also complicate positioning.
Hidden damage can be a bigger cost driver than the door itself. Replacing a short section of soft sill may add $100-$300; rebuilding a rotted jamb or correcting a badly out-of-square opening can add $300-$900. A threshold that sits more than about 1 inch above or below the planned finish floor may require adjustment to maintain a tight seal and safe step.
Labor is commonly estimated at $50-$125 per installer-hour, though contractors may quote by the job. Request an allowance or approval process for concealed damage rather than assuming repairs are included.
How to lower the replacement labor bill
Keep the project to a standard-size replacement when the existing rough opening is sound. Changing door width or relocating the opening can add framing, drywall, siding, and finish work that overwhelms any savings on the door unit. Choose a prehung model with the correct handing, jamb depth, and swing before scheduling.
Remove nearby furniture and provide a clear path, but leave structural work and weatherproofing to the installer. If the old door is intact and disposal is not included, ask whether the contractor offers a lower price when the homeowner handles disposal. Get at least three written quotes that identify labor, supplies, removal, trim, and repairs separately.
Compare the same scope and door specifications, not just the bottom-line labor figure. A low quote may omit flashing, insulation, disposal, or finish carpentry that appears on another contractor’s estimate.
How many hours does a prehung door installation take
A simple replacement generally takes one installer about 4-7 hours, including removal, fitting, fastening, and basic sealing. A two-person crew may complete the same work in 3-5 hours because lifting and positioning a heavy unit is easier with help. Crew size affects the schedule but does not always reduce the total labor charge.
New construction or a replacement requiring substantial framing can take 1-2 days. Weather exposure may require temporary protection or a return visit for finish work. Contractors may charge a trip or minimum fee of $75-$200 for a small repair or separate visit.
Ask whether the quoted hours include cleanup and final adjustment of the latch and weatherstripping. A door that binds or leaks after installation may need adjustment, so clarify the workmanship warranty and service-call terms.
Regional labor prices from rural markets to major metros
Labor in lower-cost rural and small-town markets may run about 10%-20% below a national midpoint, while major coastal metros and high-cost cities can be 15%-35% above it. For the same standard replacement, that can put labor around $250-$450 in a lower-cost area versus $600-$1,000 in an expensive metro.
Travel distance, local demand, and contractor minimums affect rural quotes; urban parking, building access, and scheduling constraints can add time in cities. Regional differences are not automatic: a remote job with difficult access can cost more than a routine city installation.
Compare quotes from installers serving the same local area and ask whether travel, parking, or permit coordination is included.
Removal, water damage, and code work beyond basic installation
Old-unit removal may be included, but hauling or disposal can add $50-$150, depending on local fees and whether the old frame contains difficult materials. Rotten wood around the sill or jamb can add $100-$900 in labor and repair materials. Exterior trim replacement or siding patching is commonly priced separately.
Some locations require permits or inspections when the project changes the opening, structure, or fire-rated separation. Permit charges vary widely, often from about $50-$300, and contractor time for coordination may be extra. Energy and safety rules can also affect the specified door or installation details; requirements depend on local code and the project scope.
Have the installer inspect the sill and framing before the final quote whenever possible. Photos can help with budgeting, but concealed damage may only become clear after the old unit is removed.
Repairing the existing jamb versus replacing the whole unit
If the slab and frame are sound, replacing weatherstripping, adjusting hinges, or repairing a small section of trim may cost $100-$400 in labor. A new door slab installed in an existing jamb can cost $200-$500 in labor, but it only works when the jamb is square, sturdy, and compatible with the door.
A complete prehung replacement costs more upfront but replaces the frame and threshold as well. That can make sense when the jamb is warped, the sill is damaged, or air and water leaks persist. Choose repair only when the existing frame can provide a secure, weather-tight fit.
