Interior door installation costs vary by door type, size, and labor needs. Typical price ranges reflect hollow core versus solid core doors, prehung units, finish work, and whether new trim is required. Below is a concise look at what buyers should expect for a standard interior door project.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door slab or prehung unit | $150 | $320 | $900 | Hollow core is cheaper; solid core or insulated options cost more |
| Door hardware (knob/lever, latch, strike) | $40 | $90 | $250 | Finish options affect price |
| Labor (installation) | $150 | $320 | $700 | Includes trimming and hardware install |
| Finish/paint or stain | $50 | $150 | $400 | Solid color vs custom finish |
| Rough opening adjustments | $40 | $120 | $260 | May require frame shimming |
| Total project | $420 | $1,000 | $2,310 | Assumes single standard door in typical interior space |
Assumptions: region, door type, rough opening size, finish level, and crew availability all influence pricing.
Overview Of Costs
Interior door installation cost typically combines the door unit price with labor and finishing. For a standard 6 ft hollow core door, expect around $300-$500 for the door plus $150-$350 for labor, totaling roughly $450-$850. For a solid core or fire-rated door, total costs commonly run higher, around $900-$1,600, depending on size and hardware. Assumptions: single door, standard trim, regular business hours.

| Materials | Labor | Hardware | Finish/Trim | Permits/Delivery | Subtotal |
|---|---|---|---|---|---|
| Door unit (hollow core or solid core) | $0 | $0 | |||
| Door slab or prehung unit | $0 | $0 | $0 | $0 | $0 |
| Door hardware | $0 | $0 | $0 | $0 | $0 |
| Finish/trim material | $0 | $0 | $0 | $0 | $0 |
| Labor (installation) | $0 | $0 | $0 | $0 | $0 |
| Permits/Delivery | $0 | $0 | $0 | $0 | $0 |
Regional price differences affect total cost by up to ±20 percent depending on local market rates.
What Drives Price
Key drivers include door type suchp> hollow core vs solid core, latch set quality, and whether the opening requires frame adjustments. A 6 ft solid core door with premium hardware may add $300-$500 to the base door price. Tighter tolerances, unusual thickness, or nonstandard rough openings can push costs higher. Assumptions: standard 80 in height, 32 in width, typical hinge placement.
Ways To Save
Save by selecting stock sizes and DIY finishing where feasible. Choosing a hollow core door and standard hardware lowers both materials and labor, while prefinished options reduce finish time. If trim is already present and square, minor adjustments eliminate extra labor. Assumptions: homeowner handles minor prep; no custom carpentry needed.
Regional Price Differences
Price variation by region matters for interior door projects. In urban markets, materials and labor trend higher than suburban or rural areas. Expect roughly 10–20 percent higher in large cities versus suburbs, and 15–25 percent higher than rural regions for premium doors. Assumptions: market responsiveness, crew availability, and material sourcing.
Labor & Installation Time
Labor time directly affects cost. Typical installation takes 2–4 hours per door, with additional hours for nonstandard openings. Labor rates vary from about $60-$120 per hour depending on locality and crew expertise. A standard install with minimal adjustments falls on the lower end of this range. Assumptions: single door, typical frame condition, standard hinges.
Real-World Pricing Examples
Three scenario snapshots help estimate budgets.
Basic — hollow core door, standard hardware, no finish, plain trim. Door $180, labor 2.5 hours at $90, hardware $60, total ≈ $420.
Mid-Range — solid core door, hinged hardware set, basic brushing, light finishing. Door $380, labor 4 hours at $100, finish $120, trim $40, total ≈ $1,060.
Premium — solid core, premium hardware, full finish, minimal gaps, possible frame replacement. Door $650, labor 6 hours at $120, finish $250, trim $80, total ≈ $1,970.
Assumptions: room conditions permit straightforward install; no structural framing changes; standard hinge locations.
Frequently Asked Price Questions
Q: Do I need permits for interior door replacement? A: Most projects do not require formal permits unless wiring or structural work is involved. Local rules may vary. Competitive shops often include basic disposal in labor quotes.
Q: How long does interior door installation take? A: Most jobs are completed in 2–4 hours per door, depending on opening condition and finish work. Larger or custom doors extend timelines.
Q: Can I install doors myself to save money? A: Basic hollow core doors with standard hardware are feasible for DIY, but trimming and shimming can be precise; poor alignment raises costs downstream.
