What affects the cost?
- Door type/opening mechanism — bifold runs $100-$300 installed, pocket doors $800-$2,500, and French doors $600-$6,000, since more complex hardware and tracks take more labor (Angi, HomeAdvisor)
- Material — hollow core is cheapest at $30-$400, solid core runs $70-$500, and solid wood/premium prehung units cost $160-$590 (HomeAdvisor)
- Slab vs. prehung — a slab door averages $300-$500 installed, while a prehung unit (already set in its own frame) runs $450-$1,000 (Angi)
- Door size — larger openings cost more for both materials and labor, sometimes double the price of a standard door (HomeAdvisor)
- Labor rate — typically $40-$90 per hour (HomeAdvisor, Bob Vila) or $44-$83 per hour (Fixr), with about 2-3 hours of work (roughly $350 in labor) for a standard swap in an existing frame (Angi, HomeAdvisor)
- Frame replacement — swapping the doorframe itself adds $220-$370 on top of the door and labor (HomeAdvisor, Angi)
- Trim and casing — $0.50-$1.50 per linear foot (up to $5 for premium trim), which works out to roughly $20-$100 per door installed (HomeAdvisor, Angi)
- Hardware — hinges run $8-$50 per door and knobs/locks range from $20 to $200 depending on style (HomeAdvisor, Angi)
- Old door removal and disposal — typically $20-$50, more if the installer charges dumping fees (Angi, HomeAdvisor)
How much does it cost to install an interior door?
A typical interior door installation runs $363 to $1,243, averaging $803 per door (Angi, HomeAdvisor). Fixr’s data points to a narrower, lower band of $374 to $697, and Thumbtack cites a national average range of $302 to $937 — all three cluster around a few hundred dollars for a standard door swap. Bob Vila’s figures land close to Angi and HomeAdvisor’s, at $375 to $1,125 or more if the frame also needs replacing. The spread comes down mostly to door type and material: a basic hollow core bifold door costs $100 to $300 installed, while a pocket door — which requires opening the wall to build a slide-in cavity — runs $800 to $2,500 (Angi, HomeAdvisor). At the top end, French doors cost $600 to $6,000 installed depending on glass and configuration.
Slab or prehung — which costs less to install?
A slab door — just the door slab, no frame or hardware — averages $300 to $500 installed. A prehung door, which arrives already set in its own frame, costs more at $450 to $1,000 (Angi). The tradeoff isn’t only price: a prehung unit is generally quicker to hang, since the hinges and frame are pre-aligned, while a slab door needs an existing frame in good condition and typically requires drilling for the knob and hinges on-site. HomeAdvisor’s data backs the same split, pricing prehung sets from $60 up depending on material and putting installed slab-door cost at $300 to $500 including materials and labor. If your current frame is square and undamaged, a slab replacement is usually the cheaper route since it skips the $220-$370 cost of a new door frame.
What drives the price up or down?
A handful of factors explain most of the gap between a $363 job and a $1,243+ one:
- Door type and opening mechanism. Bifold doors run $100-$300 installed; pocket and French doors, which need more labor and hardware, run $800-$2,500 and $600-$6,000 respectively (Angi, HomeAdvisor).
- Material. Hollow core costs $30-$400 for the door alone, solid core $70-$500, and solid wood or premium prehung units $160-$590 (HomeAdvisor).
- Frame condition. Reusing an intact frame avoids the $220-$370 cost of replacing it (HomeAdvisor, Angi). If the opening itself needs to change, expect more scrutiny of what’s inside the wall: Ken Bennett, a general contractor at Home Experts, LLC, says a wider opening starts with a structural check — “first, we check the ceiling and floor joists and whether a support beam is needed” (Angi) — before any wiring or plumbing gets rerouted.
- Labor rate. Installers typically charge $40-$90 per hour (HomeAdvisor, Bob Vila) or $44-$83 per hour (Fixr), with about 2-3 hours of work for a standard swap.
- Trim and hardware. Trim runs $0.50-$1.50 per linear foot (roughly $20-$100 per door installed); hinges cost $8-$50 per door and knobs or locks run $20-$200 (HomeAdvisor, Angi).
- Old door removal. Hauling away the existing door typically adds $20-$50 (Angi, HomeAdvisor).
How do you keep interior door costs down?
- Keep your existing frame if it’s still square and undamaged. Swapping just the door slab avoids the $220-$370 frame-replacement cost (HomeAdvisor, Angi).
- Choose hollow core for low-traffic or low-privacy rooms like closets, and reserve solid core or solid wood for bedrooms and bathrooms where sound and durability matter more — the difference is $30-$400 versus $70-$590 for the door alone (HomeAdvisor).
- Stick with standard traditional or bifold styles over pocket or French doors if budget is the priority — the labor and hardware for pocket and French installations pushes cost several times higher (Angi, HomeAdvisor).
- Batch multiple doors into one project if you’re replacing several at once; buying doors from one supplier and having one crew do the whole job in a single visit is typically more efficient than spreading it across separate jobs.
- Get several local quotes, especially if any door lock or hardware upgrades, trim work, or frame replacement is part of the job, since labor and add-on pricing vary by contractor.
Prices vary by region, door size, and material, so treat the figures above as a planning budget. Confirm whether the quote includes frame work, trim, hardware, and old-door disposal before you commit — see our prehung door installation guide if you’re focused specifically on entry-door pricing, or our French doors cost guide for interior vs. exterior French door pricing.

Frequently asked questions
How much does it cost to install one interior door?+
Most homeowners pay $363 to $1,243 per door, averaging $803 (Angi, HomeAdvisor). Fixr's figures run lower at $374 to $697, and Thumbtack's national average range is $302 to $937 — all in the same general ballpark for a standard door swap.
What's the difference between slab and prehung door installation cost?+
A slab door — just the door itself, with no frame or hardware — averages $300 to $500 installed. A prehung door, which comes pre-set in its own frame, costs more to install at $450 to $1,000, but it's generally faster to hang since the frame and hinges are already aligned (Angi).
How much more does solid core cost than hollow core?+
Hollow core doors cost $30 to $400 for the material, with most homeowners paying $50 to $150. Solid core runs $70 to $500, with most paying $70 to $250 (HomeAdvisor). Solid core costs more but blocks more sound and holds up better to impact.
How much does it cost to replace all the interior doors in a house?+
None of the major cost sources publish a single whole-house total — the price scales directly with how many doors you're replacing. Multiply your expected per-door cost (see the door-type breakdown above) by your door count, and expect some savings on materials if you buy multiple doors from the same supplier at once.
What's the most expensive interior door style to install?+
French doors top the list at $600 to $6,000 installed, driven by the glass panels and pair configuration. Pocket doors follow at $800 to $2,500, since they require opening the wall to build a slide-in cavity (Angi, HomeAdvisor).
Does the installation cost include the frame and trim?+
Not usually. If your existing frame is in good shape, you can skip that cost. A new doorframe adds $220 to $370, and trim runs $0.50 to $1.50 per linear foot — about $20 to $100 per door — unless a source states otherwise (HomeAdvisor, Angi).
How much does labor alone cost for an interior door?+
Labor typically runs $40 to $90 per hour (HomeAdvisor, Bob Vila) or $44 to $83 per hour (Fixr). A standard swap into an existing frame takes about 2 to 3 hours, or roughly $350 in labor (Angi, HomeAdvisor).
What's the cheapest way to install an interior door?+
Choose a hollow core slab door and reuse your existing frame if it's still square and undamaged. That combination avoids the $220-$370 frame-replacement cost and keeps the door itself in the $30-$400 range (HomeAdvisor, Angi).

- Fixr — Interior door installation costs range from $374 to $697 per door installation. Labor $44-$83 per hour, projects typically taking 1-3 hours, potentially reaching $249+ for complex jobs. By style: bifold $191-$356, prehung lauan slab door $365-$679, barn doors $425-$791, bypass sliding doors $477-$888, pocket doors $1,008-$1,876, French doors $1,076-$1,999, Murphy (bookcase) doors $1,278-$2,379. Hollow-core is the most affordable option; solid wood and glass options cost significantly more.
- Bob Vila — The price for an interior door can range from $375 to $1,125 (or more if the frame needs to be replaced). Composite wood door material averages $40-$500. Homeowners can expect to pay $50 to $200 or more to install a solid core door; a hollow core door starts at around $40. Labor to install a door runs $40-$90 per hour, average close to $70 per hour for a licensed contractor. A replacement door frame costs on average $250. Replacing a door in an existing frame usually starts at $40 and reaches as high as $500. A pre-hung door can be installed in less than an hour; a blank/slab door without hinges or a frame can take 3-6 hours.
- Thumbtack — The national average price to install an interior door is $302-$937, with a low end of $137 and a high end of $2,144. Pre-hung doors are typically quicker and less expensive to install than fitting a slab door into an existing frame. Hollow-core composite doors are typically more affordable; solid-wood construction costs more. The cost of new hinges, knobs, and locks adds to the total, with prices varying by style and brand.
Angi and HomeAdvisor are commonly owned and publish the same underlying cost dataset, so their headline figures match almost exactly: average $803, typical range $363-$1,243, with a stated low end of $150 and high end of $2,700. Fixr reports a narrower, lower band ($374-$697 per door) and Bob Vila a comparable but slightly wider one ($375-$1,125+), while Thumbtack's stated national average range runs lower still ($302-$937, with a $137 low end and $2,144 high end). national_average_usd and range_low_usd/range_high_usd here follow the Angi/HomeAdvisor figures because they're the most detailed and largest-sample U.S. dataset (Angi cites data from over 4,500 members) and sit centrally among the other sources' ranges. The by_type table blends material-only pricing (hollow core, solid core, solid wood) with fully-installed pricing by door style (slab, prehung, bifold, barn, sliding, pocket, French) and by configuration (slab vs. prehung) — each row is labeled to make clear which it is. Angi and HomeAdvisor's own by-style tables agree closely on bifold, pocket, French, and barn doors but diverge on sliding doors (HomeAdvisor's $400-$4,500 total-installed figure vs. Angi's narrower $250-$500, which reads as a labor-only figure for sliding bypass doors); the by_type table uses HomeAdvisor's fuller installed-cost figure. None of the sourced guides publish a single 'whole-house' replacement total — that cost scales directly with door count, so the guide describes it as a multiple of the per-door figures rather than inventing an aggregate number. Figures generally include the door, hardware, and standard installation labor; frame replacement, trim, and old-door removal are typically priced as separate line items unless a source states otherwise.
