Door installation labor typically costs $150-$900 per opening, with a national midpoint near $400 for straightforward work. Door type, frame condition, removal needs, and local labor rates drive the final quote; materials are usually separate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Interior prehung door labor | $150 | $275 | $450 | Standard opening and trim kept simple |
| Interior slab door labor | $100 | $225 | $375 | Existing jamb is usable |
| Exterior prehung door labor | $350 | $650 | $1,100 | Weather sealing and alignment included |
| Sliding patio door labor | $500 | $850 | $1,500 | Large unit; access and removal affect price |
Assumptions: Typical U.S. contractor rates, one standard-size opening, and no major framing or structural repairs.
What door installation labor usually costs
For a standard interior door, labor is commonly $150-$450; exterior door installation is more often $350-$1,100 because the installer must manage weatherproofing, threshold fit, and security hardware. A large patio slider can require $500-$1,500 in labor. These figures exclude the door, hardware, and significant repairs.
A straightforward interior replacement often lands around $275 in labor, while exterior projects typically cost more because they require precise sealing and fitting. Rates vary by market and scope, so estimates should identify whether casing, trim, and disposal are included.
How jamb work, trim, and removal shape the quote
Labor is only one part of a door estimate. A quote may include removal, fitting, shimming, fastening, casing, and cleanup. The table separates common charges; some contractors combine tasks into a single installation price.
| Quote item | Typical price | What it covers | Common cost trigger |
|---|---|---|---|
| Door installation labor | $150-$1,100 per opening | Set, level, secure, and test door | Exterior or oversized unit |
| Old door and frame removal | $50-$200 | Take out existing assembly | Heavy door or difficult access |
| Trim or casing labor | $75-$250 per opening | Fit and finish around the frame | Custom profile or repainting |
| Frame or jamb repair | $100-$500 | Minor rot, damage, or alignment work | Water damage or out-of-square opening |
| Disposal | $25-$100 | Haul away old door and debris | Local disposal charges |
Ask whether removal, trim, and disposal are included before comparing bids, since a low installation rate may exclude these tasks. Major rot or framing repairs can exceed the minor-repair range.
Which door type and opening conditions raise labor
A slab door is generally cheaper to hang when the existing jamb is straight, intact, and sized correctly. A prehung unit includes its own frame but takes more time to install and align. Exterior doors add weatherstripping, sill adjustment, and careful sealing; fire-rated, solid-core, oversized, or custom doors can also require more handling.
Opening dimensions matter. Widening an opening beyond about 2 inches, correcting a frame that is out of square by more than 1/4 inch, or replacing damaged framing can add $150-$700 or more in labor. A 36-inch-wide exterior door may take longer than a standard 30- or 32-inch interior door, especially if the old assembly is heavy.
Frame condition and door size can change a routine replacement into carpentry work. Confirm that the quote states whether it covers only fitting or also resizing, structural repair, and finish work.
How many labor hours does each installation take
A contractor may spend 2-4 hours on a basic interior slab, 3-6 hours on a prehung interior unit, and 4-8 hours on an exterior prehung door. A patio slider can take 5-10 hours, particularly when two workers are needed to move and set the glass assembly. Complex repairs or custom fitting can extend the schedule.
When billed hourly, residential carpentry rates often fall around $50-$100 per worker-hour, with higher charges in expensive metro areas. A two-person crew working 5 hours at $75 per hour costs $750 in labor before materials or fees.
Compare the stated labor hours and crew size as well as the total bid. A fixed-price quote can be easier to budget, but it should define the work included and the rate for unexpected repairs.
When removal, access, or repairs add extra charges
Removing an old door may add $50-$200, while disposal commonly adds $25-$100. Tight stairways, upper floors without elevator access, long carries, or limited work space can increase labor by roughly $50-$250. Painting, staining, new lock installation, and extensive casing work may be priced separately.
For exterior doors, hidden water damage around the sill or jamb is a frequent source of change orders. Minor repairs may add $100-$500; extensive rot or framing replacement can push labor above $700. Ask the installer to explain how concealed damage will be priced before work begins.
Written change-order rates help prevent surprises when removal exposes damaged framing. A diagnostic visit may be free or cost $50-$150, often credited toward the project.
Regional labor rates differ across U.S. markets
Large metropolitan areas on the coasts may run about 15%-35% above the national midpoint. Mid-sized cities often fall near typical pricing, while rural areas may be 5%-20% lower but can add travel or minimum-service charges. These differences are not fixed: contractor availability, building age, and local demand can outweigh broad regional averages.
Compare at least three local estimates using the same door type and scope. A useful bid lists the labor amount, removal, trim, disposal, hardware installation, and any allowance for repairs.
Local written quotes are more useful than national averages when the opening needs repairs or the property has access limits. Confirm that each installer has included the same tasks before treating the lowest total as the best comparison.
Which choices reduce door installation labor
Keeping a sound jamb can make a slab replacement less expensive than replacing the full prehung assembly, but the existing frame must be square and compatible with the new door. Choosing a standard size and profile also reduces cutting and fitting. Homeowners can clear the work area and move furniture beforehand, but removing trim or an exterior door without experience can damage the opening.
Bundle several doors in one visit when practical; the contractor may reduce setup time per opening. Schedule nonurgent work during a less busy period, and request separate prices for painting, upgraded hardware, and optional trim changes. Avoid paying for frame replacement if inspection confirms the existing jamb is sound.
Scope control, standard sizing, and comparable itemized quotes are the most practical ways to limit labor expense. Do not remove weather protection or necessary repairs from an exterior-door job just to lower the initial price.
