Owners typically pay for labor when installing a pre-hung interior door, with the main cost drivers being door size, frame condition, and finish work. The price range reflects variations in local labor rates, door rough openings, and whether trimming or hardware installation is included. This guide provides a practical cost framework in USD, with clear low–average–high ranges and real-world drivers.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor for Door Install | $180 | $350 | $650 | Typical single-door installation; higher for complex frames. |
| Hardware & Trim Labor | $50 | $120 | $200 | Includes hinges, latch, and minimal casing finish. |
| Materials (Door Shims, Fasteners) | $20 | $50 | $100 | Assumes standard 6’8” pre-hung solid-core door. |
| Permits/Inspections | $0 | $0 | $0 | Usually not required for interior doors. |
| Delivery/Disposal | $0 | $25 | $60 | Local disposal fees may apply. |
| Warranty & Follow-Up | $0 | $25 | $60 | Limited workmanship warranty often included. |
Overview Of Costs
Cost to install a pre-hung interior door includes labor to fit the door slab within the existing rough opening, adjust the hinges, and ensure proper operation. A typical project spans data-formula=”hours_labor × hourly_rate”> on-site hours, often 2–6 hours depending on conditions. A standard single pre-hung door with basic trim yields a total range around $350–$650, while more involved scenarios can exceed $700 if the door requires extensive shimming, resizing, or reclaimed hardware. The per-unit cost analysis below assumes a single door and standard materials.
Cost Breakdown
Labor, Hours & Rates often dominate the price. A typical crew charges $70–$120 per hour, with 2–6 hours of work for a straightforward install. For doors with rough openings that need resizing or a non-standard jamb, expect 6–10 hours or more in some cases. The following table shows a practical 4-column view of major cost blocks.
Assumptions: region, specs, labor hours.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $20 | $50 | $100 | Shim material, screws, nails, casing adhesive. |
| Labor | $180 | $350 | $650 | Includes door fitting, hinges, latch alignment. |
| Delivery/Disposal | $0 | $25 | $60 | Transport to site and debris removal. |
| Warranty & Misc. | $0 | $25 | $60 | One-year workmanship coverage is common. |
| Permits | $0 | $0 | $0 | Interior work typically requires no permit. |
Factors That Affect Price
Door size and hinge count are primary drivers. A standard 6’8” hollow-core door with 3 hinges is at the lower end, while a solid-core door or a 8’ door with four hinges increases labor and materials. Assumptions: standard door, square opening.
The rough opening condition matters: if the jamb is damaged, requires removal of existing trim, or the jamb is out-of-plumb, expect extra hours and potential material cost. For unusual finishes or pre-finished molding, trimming time can be longer. Assumptions: typical framed opening; no plumbing or electrical work.
Regional labor rates can shift costs by ±10–25%. In urban centers, labor often sits at the higher end of the range, while rural areas tend toward the lower end. Assumptions: no decorative glass or specialized hardware.
Where The Money Goes
Cost Components break down into labor, materials, and incidental items. Labor covers installation, adjustment, and hardware alignment. Materials include the door itself, hinges, strike plate, screws, shims, and any trim pieces. Hidden costs may include delivery fees or disposal of old doors. Assumptions: and no major structural corrections needed.
Regional Price Differences
Prices vary by region. In the Northeast and West Coast, expect roughly 10–20% higher labor rates than the national average due to higher living costs. In the South and Midwest, rates typically run 5–15% below the high-end urban brackets. Assumptions: single-door install, standard materials.
Labor & Installation Time
Most basic installs take 2–4 hours; more complex jobs can take 4–6 hours or longer. A single installer with standard tools can usually complete the job, while crews can speed up timelines for multi-door jobs. Shorter times correlate with straightforward openings and exact door matching. Assumptions: no structural work or HVAC changes needed.
Additional & Hidden Costs
Hidden costs may include mismatched hardware, specialty trim, or removing an old door and jamb. If pre-hung doors require custom casing or reclaimed hardware, per-unit costs can rise by $50–$200. Always confirm included items before quoting. Assumptions: standard doorway; no cosmetic refinishing beyond initial trim.
Real-World Pricing Examples
Three scenario cards illustrate realistic outcomes, with specs, labor hours, per-unit prices, and totals. Each scenario assumes a standard interior door and basic hardware.
- Basic — Hollow-core single door, standard 6’8”, 2 hinges; labor 2–3 hours; door labor $180–$270; total $350–$430; per-unit $70–$130/hour.
- Mid-Range — Solid-core, pre-finished trim, 3 hinges, latch hardware; labor 3–5 hours; total $350–$550; per-hour $70–$110; materials $40–$90.
- Premium — Solid-core with long jamb, decorative casing, concealed hinges, upgraded latch; labor 5–8 hours; total $600–$900; materials $60–$120; extra trim $50–$120.
These spreads reflect realistic field conditions where opening sizes vary and finishes affect trim complexity. For multi-door projects, economies of scale can reduce per-door labor, while mismatched existing trim may raise time on site. Assumptions: typical interior doors; no structural remodeling.
