Homeowners typically pay a combined price for labor, materials, and finishing when installing a prehung door. Main cost drivers include door type, frame material, trim work, and whether framing or alterations are needed. The following sections present practical price ranges and breakdowns to help set a realistic budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Prehung door unit | $150 | $350 | $1,000 | Includes door slab, frame, and hinges; interior vs exterior varies. |
| Hardware & trim | $50 | $150 | $400 | Knobs/locks, casing, shims, caulk. |
| Labor (installation) | $200 | $450 | $1,200 | Hours depend on door size, framing, and alignment. |
| Materials & supplies | $50 | $150 | $350 | Adhesives, nails, sealant, shims. |
| Delivery & disposal | $20 | $60 | $150 | Transport and removal of old door. |
| Permits (if required) | $0 | $60 | $250 | Typically minimal for interior doors. |
| Warranty & workmanship | $0 | $40 | $120 | Often included or optional. |
Assumptions: region, specs, labor hours.
Overview Of Costs
Typical project ranges reflect interior and exterior doors, standard 6’8″ height, and common framing. A budget install may total around $450-$1,100, while mid-range projects usually land in the $1,000-$2,400 band, and premium exterior or custom doors can exceed $3,000. The per-unit pricing often includes the door and hardware, with labor making up a large share of the total in most homes.
Per-unit ranges or combined totals help buyers compare options quickly. For example, a basic interior prehung door with minimal trimming might be $250-$600 including labor, whereas a high-end exterior prehung door with steel or fiberglass and extensive trimming could be $1,800-$3,500 or more depending on size and finishing.
Cost Breakdown
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $120 | $300 | $900 | Door type strongly affects cost (solid wood vs fiberglass). |
| Labor | $200 | $450 | $1,200 | Includes removal of old door, frame checks, and trim work. |
| Hardware | $40 | $120 | $320 | Latches, hinges, handles, and strike plates. |
| Permits | $0 | $40 | $150 | Occasional permit or inspection fee for renovations. |
| Delivery | $10 | $50 | $120 | Door delivery and haul-away of old unit. |
| Overhead & Profit | $20 | $60 | $180 | Contractor margin and business costs. |
| Taxes | $10 | $40 | $120 | Sales tax varies by state. |
| Contingency | $20 | $60 | $200 | Buffer for unexpected framing issues. |
Pricing Variables
Door type and installation complexity drive a large portion of the cost. Exterior prehung doors with energy-efficient cores and weather seals add material and labor time. Interior doors with hollow cores and standard trim are the most economical. A few niche drivers include: weather resistance, insulation ratings, and door height or width beyond standard sizes.
Regional price differences can shift totals by 10-25% depending on material availability and local labor rates. In urban markets, rates tend to be higher due to higher overhead, while rural areas may see more modest pricing.
Ways To Save
Shop door options with standard sizes to minimize custom millwork. Use existing jambs if plumb and square, or choose stain-grade materials only if trim is already present. Scheduling during off-peak seasons can also reduce labor costs in some markets.
Bundle with related work such as hinge replacements or framing corrections to leverage contractor travel time and possibly a small discount. Confirm whether hardware is included or if a separate purchase is needed.
Regional Price Differences
Three-region comparison shows how costs diverge. In the Northeast, higher material costs and labor rates commonly push totals toward the upper end. The Southeast tends to be more affordable on interior installs but may vary for exterior doors due to climate considerations. The Midwest often sits between extremes, with solid mid-range pricing and occasional regional promotions.
Labor & Installation Time
Typical installation time ranges from 2 to 6 hours, depending on door size, whether reframing is required, and if existing jambs are plumb. The formula data-formula=”labor_hours × hourly_rate”> can help estimate labor costs if an hourly rate is known.
Additional & Hidden Costs
Hidden costs may include asbestos checks in older homes, structural repairs, or repainting damaged trim. If the existing opening is out of plumb, extra shims or new framing can add $150-$900 to the project. Exterior doors may require heavier weatherproofing and threshold adjustments.

Scenario B — Mid-Range Interior: Solid-core interior prehung with pre-finished trim. Door $350, Labor $450, Hardware $120, Delivery $40, Taxes $40. Total: $1,000. Assumptions: minor framing checks, slight trim adjustment.
