How Much Does Interior Door Installation Cost in 2026?

By Michael JohnsonUpdated November 11, 20268 sources comparedHow we estimate

Most homeowners pay $300 to $900 per door to have an interior door installed, with a typical cost of about $550 for a standard prehung door, labor included. That figure is the median of the per-door midpoints published by HomeGuide, Fixr, Homewyse and Thumbtack, with HomeAdvisor's higher $797 average as the upper check. What you pay depends mostly on whether you buy a slab or a prehung unit, the door's core (hollow, solid-core or solid wood), the style, and whether the opening needs framing work.

Interior door installation cost by door type

The table compiles installed prices (door plus labor) from several national cost guides. The QuoteRuler range is where those sources overlap for a typical single door in an existing opening.

The sources disagree mainly on scope. HomeGuide's $344 national average reflects a lot of simple swaps of hollow-core doors. HomeAdvisor's $797 average (most pay $362–$1,232) includes more frame, trim and style changes, and its own data puts labor at about half the bill. Homewyse prices a basic 30" x 80" hollow-core slab job at $444–$675 for May 2026, but that excludes the lockset, finishing and moldings. Thumbtack's 2026 range of $302–$937 sits in the middle.

Slab vs. prehung doors

A slab is just the door. It fits an existing frame, so the installer has to trim it to size, cut hinge mortises and drill for the lockset. HomeGuide notes slabs cost about half as much as prehung units to buy ($30–$300 for the door), but take more labor, which it puts at $200–$570 per slab. Drilling a blank slab for hardware alone adds $95–$150.

A prehung door comes already hung in its own jamb with hinges attached. It costs more up front, but it goes in faster and usually hangs straighter, especially in an older house with an out-of-square frame. HomeGuide lists standard prehung labor at $120–$170 and prehung materials at $50–$300.

Choose a slab when the existing jamb is solid and square and you want to keep original trim. Choose prehung when the frame is damaged, the door binds, or you are changing the door size.

Hollow-core vs. solid-core vs. solid wood

• Hollow-core doors are the cheapest: $30–$240 for the door (HomeGuide), with most at $50–$150 (HomeAdvisor). They are light and block little sound.
• Solid-core doors have a dense composite core under a wood or molded skin. They cost $60–$330 for the door (HomeGuide) and block sound much better, which matters for bedrooms, bathrooms and home offices.
• Solid wood doors cost $250–$600 on average for the door, and installed jobs run $300–$1,200 (HomeGuide). Alder sits at the lower end; cherry, mahogany and walnut sit at the top.

Solid doors are heavier, so labor runs a bit higher. HomeGuide puts the hanging cost at $180–$460 for hollow-core and $220–$760 for solid-core.

Door styles: panel, barn, pocket, French and bifold

Panel doors (two-, five- or six-panel) and flat doors cost the same to hang as any other swing door. Price differences come from the material, not the panel pattern.

Bifold doors are the cheapest closet option. Barn doors need a header board and a sturdy track mounted into framing, not drywall alone. French doors are a pair with glass panels, so they cost more and need careful alignment. Pocket doors are the most expensive because the installer has to open the wall, install a pocket frame and patch the drywall. Expect drywall finishing on top if the contractor doesn't include it (see our drywall installation cost guide).

Labor vs. materials

Labor is a big part of this job. HomeAdvisor says labor typically makes up about 50% of the total, averaging around $350 for a 2- to 3-hour remove-and-replace. ConsumerAffairs puts the labor share at 40%–60%. Hourly rates run $30–$80 (HomeGuide) to $44–$83 (Fixr), and Fixr says a simple install takes 1–3 hours.

We use a labor share of 50% for our state adjustments. It is the midpoint of those figures. It runs lower when you buy an expensive solid wood or French door and higher for a cheap hollow-core slab that needs a lot of fitting.

Home Depot publishes labor-only prices that exclude the door. Interior installs average $178–$398, and the per-door rate falls as the job grows: $159–$798 each for 1–2 doors, $129–$718 for 3–5, and $99–$698 for 6 or more.

What drives the price up or down

• Frame condition. Fitting a door to an existing opening costs $30–$70. Reframing an opening runs $110–$220, and resizing one costs $250–$400 (HomeGuide). A new standard wood doorframe costs $220–$370 (HomeAdvisor).
• New openings. Adding a door to an interior wall costs $675–$1,100 (HomeGuide). ConsumerAffairs quotes $500–$2,000 for a new opening and door. Widening a doorway runs $300–$2,500, and more if the wall is load-bearing.
• Trim and casing. New casing costs $90–$155 per door, or $2–$4 per linear foot (HomeGuide). Homewyse prices door trim at $7.94–$12.17 per linear foot installed.
• Hardware. Replacing hardware averages $60–$200 (HomeGuide). A basic knob costs $20–$40, a high-end one $50–$200, and hinges $8–$50 per door (HomeAdvisor).
• Painting. Painting a door and frame costs $75–$150 (HomeAdvisor, HomeGuide). Dark-to-light color changes cost more because they take extra coats.
• Size and fire rating. Double doors cost roughly twice as much as a single door (ConsumerAffairs). Custom sizes add a few hundred dollars. A fire-rated door between the garage and the house costs $300–$700 installed (HomeGuide).
• Volume. Several doors in one visit cost less per door, as the Home Depot tiers above show.

Cost by state

Labor makes up about half of this job, so where you live matters. The table below starts from our national range, compiled from the sources above, and adjusts only the labor portion (50%) by each state's Bureau of Economic Analysis Regional Price Parity.

Use the state figure as a starting point. Rates inside a big metro area can run well above the state average.

Whole-house interior door replacement cost

To price a whole house, multiply the per-door cost by the number of doors, then apply a volume discount. In Home Depot's tiers, the per-door midpoint falls about 11% at 3–5 doors and about 17% at 6 or more. Applied to our prehung hollow-core range ($250–$650), a 10-door job comes to roughly $2,100 to $5,400 before trim, hardware and painting. A house of solid-core doors lands higher: about $2,500 to $6,200 at the same discount.

Bundling saves more than labor. One trip, one trim order and one paint session cover every door, so ask for whole-house pricing instead of separate quotes per door.

DIY or hire a pro?

DIY works best for a slab in a good frame, or a prehung door in an opening that is the same size and square. HomeAdvisor estimates about 2 hours for a prehung door, and under $25 in materials beyond the door and hardware. A handy homeowner saves the labor half of the bill.

Hire a carpenter for pocket doors, French doors, new or widened openings, or any frame that is out of square. A badly hung door rubs, won't latch, or leaves uneven gaps, and fixing that later costs more than doing it right. If you plan to widen an opening or move a door, ask whether the wall is load-bearing. That work needs a header sized by a pro and often a permit. Rerouting wiring or plumbing in the wall needs a licensed electrician or plumber. In homes built before 1978, cutting or sanding painted trim can release lead dust. Contractors paid for that work must follow the EPA's lead-safe Renovation, Repair and Painting rule.

Repair instead if the door is sound but sticks, sags or won't latch. Interior door repairs average $75–$220 (HomeGuide), well below the cost of a new door.

How to save money on interior doors

• Keep good frames. Hanging a slab in a sound jamb avoids frame and trim costs. Fixr notes that reusing the existing frame and jambs costs "significantly less than average."
• Bundle doors. Replace all the doors at once to get multi-door pricing.
• Use solid-core only where it counts. Put solid-core doors on bedrooms and bathrooms for sound control, and hollow-core on closets.
• Buy primed doors and paint them yourself. That saves the $75–$150 per-door painting charge.
• Supply your own door if the installer allows it, but confirm measurements and swing direction (left- or right-hand) first.
• Get at least three quotes that spell out the same door, core type and scope.

How to compare interior door quotes

A fair quote should list:

• The door type (slab or prehung), core (hollow, solid-core or solid wood), size and swing direction.
• Whether casing and trim are new or reused, and on how many sides.
• Hardware: who supplies the knobs or levers and hinges, and whether installation is included.
• Removal and disposal of the old door, which costs $40–$80 if it is extra (HomeGuide).
• Painting or staining, and whether that covers the door only or the jamb and trim too.
• Any framing, drywall patching or floor-clearance trimming.
• The labor warranty.

Red flags: a per-door price that doesn't say whether trim and hardware are included; no visit to measure before quoting a prehung order; vague wording like "install doors as needed"; and pressure to replace frames that only need adjustment.

Hidden costs people forget

• Floor height changes. New flooring can mean trimming every door bottom, and thicker floors may require raising the jamb. Plan doors after floors. Our hardwood floor installation cost guide covers the floor side.
• Drywall and paint patching after pocket doors or widened openings. Matching the wall color can turn one door into a room repaint. See our interior painting cost guide.
• Thresholds between rooms: $30–$80 installed (HomeGuide).
• Split-jamb prehung doors take an extra 30–60 minutes, about $30–$60 more (HomeGuide).
• Self-closing hinges on a garage-to-house door: $30–$80 (HomeGuide).
• Contingency. ConsumerAffairs suggests keeping 10%–15% extra for surprises such as a rotted jamb.

Bottom line

A standard prehung interior door typically costs $300 to $900 installed, and about $550 is a realistic national midpoint. Slabs in good frames cost less. Solid wood, French and pocket doors cost the most, up to about $2,500 each. Labor is about half the bill, so replacing several doors at once is the easiest way to cut the per-door price.
