Homeowners typically pay for skilled labor to install an interior door and finish trim. Key cost drivers include door material (hollow vs solid core), trim type and finish, door size, hardware, waste, and local labor rates. This guide provides a concise cost picture and practical ranges for budgeting the project.
Assumptions: region, door type, trim width, and labor hours.
Summary Table
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor (install only) | $250 | $420 | $800 | Includes framing trim, hinge mortises, and door hanging. |
| Trim & Molding Labor | $100 | $230 | $420 | Includes casing, base shoe, and joint finish work. |
| Hardware & Misc | $50 | $120 | $260 | Doorknob, latch, hinges; assuming mid-range hardware. |
| Total Project (Labor + Materials) | $370 | $770 | $1,480 | Materials vary by door type and trim choice. |
Overview Of Costs
Door installation labor costs typically range from $250 to $800, depending on door type, size, and existing frame condition. A standalone trim upgrade can add $100–$420 for labor, while hardware adds another $50–$260. Total project costs (labor plus materials) usually fall in the $370–$1,480 band, with higher figures tied to premium solid-core doors and intricate trim profiles.
Cost Breakdown
| Category | Low | Average | High | Assumptions | Notes |
|---|---|---|---|---|---|
| Materials | $120 | $260 | $520 | Door type: hollow vs solid core; trim profile; finish | Solid-core doors increase material cost and weight. |
| Labor | $250 | $420 | $800 | Framing, hinge mortises, door hanging | Single door with standard height (6 ft 8 in); no structural work. |
| Hardware | $50 | $120 | $260 | Knob/lever, latch, hinges | Mid-range hardware assumed. |
| Delivery/ Disposal | $0 | $40 | $80 | Materials transport; packaging disposal | Often included if contractor supplies materials. |
| Permits/Fees | $0 | $0 | $0 | Not typically required for interior doors | Budget if required by unique project scope. |
| Waste/Remodeling Adjustments | $0 | $30 | $60 | Small waste factor | Assumes minor adjustments only. |

Factors That Affect Price
Door type and size have a major impact. Hollow-core doors are cheaper to install than solid-core or specialty doors. A standard 6 ft 8 in door with 2-1/4 inch thickness typically costs less to install than a tall or heavy door (e.g., 8 ft or solid wood). Weight and stiffness affect crew time and equipment needs.
Trim complexity matters. Simple flat casing is quicker than multi-piece or ornate profiles. Premium woods (oak, maple) and custom stain finishes raise both materials and labor costs. Wider base trims and shoe molding add time and material use.
Existing frame condition can drive hours. If jambs are warped, out of square, or require reinforcing, labor rises. If rough opening is standard and square, installation stays at the lower end.
Hardware choices influence cost and time. Simple levers cost less than smart-lock hardware. If custom mortises or nonstandard hinges are needed, expect longer install times and higher labor charges.
Location and market affect hourly rates. Urban markets generally have higher labor costs than rural areas. Permit requirements are usually minimal for interior work, but regional labor availability can shift pricing.
Labor, Hours & Rates
Typical labor rates for interior door installation range from $60 to $120 per hour, depending on the contractor, region, and project specifics. A basic single interior door install generally requires 2–4 hours for hanging plus 1–2 hours for trim work in straightforward cases. Heavier doors or complex trim can extend by 1–3 additional hours. Projected labor cost reflects these hours multiplied by the local rate.
Ways To Save
Use standard door sizes and accessories to reduce custom work and time. Choose hollow-core doors with basic trim instead of premium solid-core doors and ornate casing to keep costs predictable. If existing jambs are square, avoid structural refinishing; only minor planing or shimming is needed in most cases.
Bundle projects with related carpentry tasks (baseboard replacement or door hardware upgrades) to negotiate a bundled labor rate with the contractor. Obtain multiple bids and request itemized estimates to compare labor hours and per-hour pricing clearly.
Do some prep yourself such as removing old door and trim, or cleaning up after demolition, to shorten professional time on site.
Regional Price Differences
Pricing varies by region due to labor markets and material costs. In the Northeast, expect higher hourly rates and premium materials; the Midwest and South typically offer mid-range pricing; the West can swing higher depending on city demand. For a typical install, regional differences can shift total labor costs by ±10–25% from the national average.
Real-World Pricing Examples
Scenario A — Basic Hollow-core door, standard casing, standard hardware, 2 hours labor, no extra framing. Door materials $120; labor $240; hardware $60; total around $420.
Scenario B — Mid-Range Solid-core door, 2-piece casing, mid-range hardware, minor jamb adjustment. Materials $260; labor $420; hardware $120; total around $800.
Scenario C — Premium Solid wood door, custom casing, upgraded hardware, potential jamb reinforcement. Materials $520; labor $700; hardware $260; total around $1,480.
Assumptions: region, specs, labor hours.
