Purchasing and installing an interior door with trim typically costs between $400 and $1,800 depending on door type, frame work, and finish quality. The labor portion is the largest driver, followed by materials and hardware. This article breaks down the cost to install interior doors and trim, with per-unit estimates and regional considerations for U.S. buyers.

Typical Labor Price Range for 80-Inch Interior Door Install with Casing
Most homeowners see labor costs between $300 and $900 for a standard 80-inch door with casing. This range covers door hanging, trimming, and hardware installation. Regional labor rates and the door’s hardware quality heavily influence the final number. Assumptions: hollow-core door, standard 3-1/4″ casing, normal access, Midwest-to-South labor rates.
Main Cost Components for Door and Trim Project
A balanced quote splits labor, materials, and hardware distinctly for a door and trim job. The table below shows a typical breakdown with per-unit ranges to help compare quotes. Assumptions: single door per opening, no structural work, standard finish.
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Labor | $120 | $240 | $520 | Door hanging, trimming, alignment |
| Materials (door) | $60 | $120 | $250 | Hollow-core or solid-core varies |
| Trim/Casing | $60 | $150 | $350 | Width and profile affect price |
| Hardware | $20 | $40 | $125 | Knob, hinge set, latch |
| Finishing | $40 | $120 | $280 | Paint or stain; prep included |
| Travel/Delivery | $0 | $20 | $100 | Nearby job sites |
Key Variables That Change the Final Quote
Door type and frame size are the strongest drivers of cost. Solid-core doors cost more than hollow-core, and custom or big-frame openings add labor and materials. Other important factors include trim width, niche molding, and any required pantry or closet rebuild. Numeric thresholds: solid-core adds ~15–40% vs hollow-core; opening height beyond 82″ increases trim length and labor by 10–25%.
Regional Labor Rate Variations for Door Install in the U.S.
Labor costs vary by region, with metropolitan areas often posting higher rates. Expect higher quotes on the coasts and in major cities compared to rural zones. Assumptions: standard door size in a single-family home, no business hours surcharge.
Crew Size, Time, and Scheduling Impact on Price
Single-crew installations typically take 4–6 hours for a standard door and trim. Adding a second crew member can reduce on-site time but may raise total labor cost if rates are higher. Assumptions: one door opening, no extra walls or framing alterations.
Per-Unit and Per-Opening Cost Elements to Watch
Hinges, knobs, and casing are charged per unit or per opening. If a project uses premium hardware or multiple doors, per-opening pricing scales accordingly. Assumptions: one opening, standard interior hardware set.
Cost-Saving Moves Without Compromising Quality
Consider standard doors and trim first, plan finishing in bulk, and verify access for the installer to avoid delays. Bundling related tasks like multiple doors or closet re-trims can save time and money. Assumptions: normal access, no structural modification required.
Optional Add-Ons That Affect the Final Bill
Finishing and refinishing, sound-rated doors, or weather stripping can add $50–$300. Evaluate whether upgrades are needed for noise reduction, privacy, or energy control. Assumptions: interior room use, standard climate conditions.
| Add-On | Low | Average | High | When It Matters |
|---|---|---|---|---|
| Sound rating upgrade | $60 | $150 | $350 | Between rooms with noise concerns |
| Premium hardware | $25 | $60 | $150 | Weighted hinges and levers |
| Special finish (stain/paint) | $40 | $100 | $200 | Custom color or sheen |
| Additional openings | $100 | $250 | $600 | Each extra doorway |
