Prices for replacing an interior door slab vary by door type, material, and labor. The main cost drivers are the door slab material, hinge/strike hardware compatibility, and installation time. A typical project involves selecting a slab, trimming or aligning to fit, and finishing with paint or stain.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door Slab (hollow core) | $40 | $70 | $150 | Lightweight, common for interior doors |
| Door Slab (solid core) | $150 | $210 | $300 | Better sound dampening and durability |
| Labor & Installation | $80 | $180 | $350 | Typically 1–3 hours depending on fit |
| Hardware & Finish | $20 | $60 | $120 | Hinges, latch, paint/stain |
| Delivery/Removal & Disposal | $10 | $25 | $50 | Waste and haul-away if needed |
| Warranty/Overhead | $10 | $25 | $60 | Contractor overhead and workmanship warranty |
Overview Of Costs
Typical project ranges cover hollow core slabs as a budget option and solid core slabs for higher durability. Assumptions include standard 80-inch interior doors, pre-hung or ready-to-install slabs, and no special frame changes. The price per unit can be $/slab plus labor, with both components varying by material and finish.
The cost range for a single interior door slab installed generally runs from roughly $120 to $450, depending on material and finish. Per-unit pricing often appears as $40-$150 for the slab itself plus $80-$350 for labor and finishing combined.
Cost Breakdown
| Category | Low | Average | High | Notes | Assumptions |
|---|---|---|---|---|---|
| Materials | $40 | $210 | $300 | Hollow vs solid core; finish | Region: urban; hollow core |
| Labor | $80 | $180 | $350 | Removal, trim, hinge alignment | 1–3 hours; standard door size |
| Hardware | $20 | $60 | $120 | Hinges, latch, strike plate | Includes paint/stain supplies |
| Overhead | $10 | $25 | $60 | Business costs | Contractor overhead |
| Taxes | $0 | $0-$10 | $20 | Sales tax varies by state | State and local rate applied |
| Contingency | $0 | $10 | $20 | Unforeseen trim or fit issues | 5–10% recommended |
What Drives Price
Material choice strongly affects cost: hollow core slabs are cheaper but thinner and lighter, while solid core slabs offer greater durability and sound insulation. Assumptions: standard 6-8 ft height, no custom shapes.
Other drivers include finish quality (paint vs stain), finish work (touched-up painting or matching trim), and hc depth/width (custom sizes add cost).
Labor time is influenced by door size, frame compatibility, and whether trimming or re-routing hinges is required. If the frame needs resizing, expect higher labor costs.
Ways To Save
Buy a matched set of slabs and hardware to reduce fit issues and waste. Consider hollow core doors for modern interiors when sound isolation is not a priority. Assumptions: standard 32″-36″ doorway, no heavy modifications.
Ask for just-in-time finishes or pre-finished slabs to minimize on-site painting. If a contractor offers a bundled price that covers slab, hardware, and finish, it often reduces overall cost variability.
Regional Price Differences
Prices vary across regions. In the Northeast, labor tends to be higher due to higher living costs, while the Southeast may offer lower labor rates but higher material shipping costs for certain finishes. The Midwest often provides a balance between materials and labor. Local market variations can swing total by ±10–25% depending on contractor availability and material sourcing.
Labor & Installation Time
Typical installation for a single interior door slab runs 1–3 hours, depending on door size, hinge type, and whether a new frame or resizing is needed. Hourly rates commonly range from $60 to $110 in many markets.
Additional & Hidden Costs
Hidden costs might include frame adjustments or jamb modifications if the existing opening differs from standard slab dimensions. Some jobs incur a small trip or delivery fee. Assumptions: standard door, no replacement jamb.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes:
- Basic — Hollow core slab, standard finish, no frame work: Door slab $40, Labor $90, Hardware $25; Total around $160.
- Mid-Range — Solid core slab, painted finish, minimal trim: Slab $210, Labor $180, Hardware $60; Total around $450.
- Premium — Solid core with premium stain, frame adjustments, new hinges: Slab $300, Labor $350, Hardware $120, Delivery $25; Total around $795.
Assumptions: standard interior doors; local tax varies; quantities per project may differ.
