New interior doors typically cost $150-$1,500 per opening, including a standard door and installation; the average is about $450-$700. Price depends on door material and style, whether the existing frame can stay, hardware, labor, and local rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Door slab only | $40 | $150 | $800+ | Hollow-core to solid wood or specialty designs |
| Prehung door and installation | $150 | $450-$700 | $1,500+ | Includes a new frame and standard fitting |
| Slab replacement and installation | $100 | $250-$500 | $900 | Uses a serviceable existing frame |
| Hardware and finishing | $15 | $75-$200 | $500 | Knob, hinges, paint, or stain, depending on scope |
New interior door prices by style and installation
A basic hollow-core door slab usually costs $40-$150, while a molded-panel slab often runs $70-$250. Solid-core doors commonly cost $150-$500, and solid-wood or custom doors can reach $300-$1,000 or more before installation. A prehung unit includes the door attached to its frame and generally costs more than a slab.
For a typical 30-by-80-inch bedroom opening with standard trim and no framing repairs, expect about $150-$350 for a hollow-core prehung door installed, or $350-$800 for a solid-core option. Specialty glass, oversized openings, custom finishes, and premium wood raise the total. For a standard replacement, budget roughly $450-$700 per opening before unusual repairs or upgrades. Assumptions: typical U.S. labor rates, standard opening, readily available door, and normal access.
What door, labor, and hardware add to the quote
Quotes vary in what they include. A door-only price may exclude the frame, hinges, knob, paint, delivery, and disposal. Ask whether the contractor is pricing a slab replacement or a complete prehung-door installation, and whether trim will be reused.
| Quote item | Typical price | What changes the charge |
|---|---|---|
| Hollow-core or molded door | $40-$250 per slab | Size, panel design, and finish |
| Solid-core door | $150-$500 per slab | Weight, sound rating, and style |
| Installation labor | $100-$300 per door | Slab fit versus frame replacement |
| Lockset and hinges | $15-$150 per opening | Basic passage set versus premium hardware |
| Painting or staining | $50-$200 per door | Number of coats and finish condition |
| Removal and disposal | $20-$100 per door | Old door weight and disposal access |
Contractors may charge a minimum service fee for one door, making each opening more expensive than a multi-door project. Confirm that the estimate identifies materials, labor, finishing, and removal separately.
How opening size and frame condition change the price
Standard-size doors, commonly 24-36 inches wide and 80 inches tall, are usually less expensive and easier to source than unusual dimensions. A door that needs cutting, a nonstandard width, or a custom order can add $50-$300 or more, depending on material and availability.
Frame condition is another major variable. A slab replacement may work when the jamb is square, solid, and compatible with the new door. If the frame is damaged, out of square, or the wrong size, a prehung replacement may add $100-$400 in materials and fitting. Moving or enlarging an opening can cost several hundred dollars more, especially if wall, electrical, or trim work is needed. Check the opening and jamb before comparing slab-only quotes with full-frame quotes.
Cut the price by keeping sound frames and choosing standard doors
Retaining a straight, undamaged frame and replacing only the slab can save money, but the new door must match the opening, hinge locations, and swing. Standard sizes and stocked designs typically cost less than custom widths, specialty finishes, or premium wood. A hollow-core model is often adequate for a closet; solid-core may be worth the added cost for a bedroom or home office where sound control matters.
Buying several doors at once can reduce per-door delivery or labor charges, though savings depend on the contractor and product. Homeowners can sometimes save by removing old doors or painting new ones, but should agree on the scope first; incorrect hinge mortises or cuts can damage a door. Prioritize a compatible standard-size door and avoid paying for frame replacement when the frame is sound.
Regional labor rates shift installed door totals
Labor and contractor overhead are often higher in major coastal metros than in rural markets. As a rough planning adjustment, urban areas in the Northeast and West Coast may run 10%-25% above a typical national estimate, while some rural or lower-cost Midwest and Southern markets may be 5%-15% below it. These are broad differences, not guaranteed local quotes.
For example, a standard prehung door project that costs $450-$700 in a mid-priced market might land around $500-$875 in a high-cost metro, or $380-$650 in a lower-cost area. Travel distance, parking, building access, and local demand can also affect a small job. Compare at least two local written quotes with identical door and finishing specifications.
How long installation takes and what labor covers
A straightforward slab replacement may take about 1-2 hours, while fitting a prehung unit commonly takes 2-4 hours per opening. A carpenter or door installer may charge about $50-$125 per hour, though many quote a flat amount per door. Painting, trim work, or correcting a rough opening adds time.
Labor generally covers removal, fitting, leveling, fastening, and basic hardware installation. It may not include painting, new casing, wall repair, or moving furniture. Replacing several doors can take a crew most of a day or longer, depending on the number and condition of openings. Ask how many labor hours or installation steps are included in the flat rate.
Three common interior door replacement budgets
A single standard 30-by-80-inch hollow-core prehung door with basic hardware and uncomplicated installation may total $250-$450. A solid-core bedroom door in the same opening, including standard hardware and paint, may run $500-$900. A custom-width solid-wood door with frame work, upgraded hardware, and finishing can reach $1,000-$2,000 or more.
For a five-door project, standard hollow-core replacements might total $1,000-$2,000, while five solid-core doors may cost $2,500-$4,500 installed. These examples assume ordinary access and no structural changes; local labor and finish expectations affect the final bill. Use the same door type, size, hardware, and finishing scope when judging whether a quote is high or low.
