- Prices vary most by: The door unit — pre-hung or slab (40–50% of the budget)
Cross-checked against three published sources for this project. Sources used for this page: the HomeGuide interior door and door installation cost guides, Angi's interior door cost data and EngineerFix's interior door cost guide. Sources last checked: October 2026 — HomeGuide, Angi. Last updated October 2026 · How we calculate these costs
Cost by scope
| Scope | Typical cost | What it includes |
|---|---|---|
| Hollow-core or bifold closet door | $120 – $400 | The budget end: HomeGuide totals a hollow-core replacement at $120–$380 complete, and Angi prices bifold doors at $100–$300 nationally — light doors, the existing jamb kept, basic hardware |
| Standard pre-hung solid-core door — the typical job | $300 – $700 | The typical band on this page: HomeGuide totals a complete solid-core install at $150–$680 and pre-hung installation at $170–$470 with materials, EngineerFix runs a standard door at $438–$666 installed, and HomeGuide puts most door purchases at $100–$500 with $120–$300 of labor |
| Solid wood, French or pocket door | $700 – $2,500 | HomeGuide prices solid wood installed at $300–$1,200, single French doors at $200–$800 and pocket doors at $500–$2,500; Angi's national table runs pocket doors at $800–$2,500 and French doors higher still — real wood, glass and work inside the wall are the spend at this tier |
Where the money goes
| Part of the job | Share | Note |
|---|---|---|
| The door unit — pre-hung or slab | 40–50% of total | The door itself is the largest line: HomeGuide puts most door purchases at $100–$500, with pre-hung materials at $50–$300 before labor and solid-core units at the top of the standard ladder |
| Installation labor | 30–40% | HomeGuide prices labor at $120–$300 on a replacement ($120–$170 for a pre-hung unit, about 1–2 hours) and EngineerFix puts labor alone at $100–$300 — a slab costs more to hang than a pre-hung because the hinges and lock bore are cut on site |
| Hardware, casing & trim | 8–15% | Knob or lever, hinges and the casing that finishes the opening: HomeGuide prices hardware at $30–$150 and a replacement jamb at $50–$300 when the frame is changed rather than reused |
| Old door removal & adjustments | 5–10% | Taking the old door out runs $40–$80 in HomeGuide; reframing a settled opening adds $110–$220 and resizing an opening $250–$400 when the swap is not like for like |
What moves the price most
Pre-hung versus slab is the interior door budget. A pre-hung unit arrives hinged in its frame, so the fitting was done at the factory: HomeGuide prices pre-hung installation at $170–$470 all-in with labor at $120–$170, while a slab is cheaper to buy and dearer to hang, because the installer mortises the hinges, bores the lock and fits the door to an existing frame on site. Core and material are the second lever: HomeGuide totals a hollow-core door at $120–$380 complete against $150–$680 for solid-core and $300–$1,200 for solid wood — the solid-core door is the standard recommendation for bedrooms and bathrooms because it carries sound and feels like a door, not a shell. Door type is the third: bifolds and bypass sliders are the cheapest doors in Angi's national table ($100–$300), French doors price at $200–$800 for a single in HomeGuide, and a pocket door at $500–$2,500 because its track lives inside the wall. Finally, the opening decides the surprise line: a sound, square frame keeps the job a swap; reframing runs $110–$220 and resizing $250–$400 in HomeGuide, and both are discovered when the old door comes out, not before.
Worked example: how a typical interior door installation budget breaks down
A typical job: one standard pre-hung solid-core door replacing a worn bedroom door in the same opening — old door removed and hauled away, new unit hung, levelled and latched, hardware fitted, casing touched up. The budget below totals $450 — the "most homeowners pay around" figure from the top of this page — split using this page's own cost breakdown. It shows how a real quote at that level is usually composed; every line is built from the ranges on this page, and it is an illustration, not a quote for your project.
| Line item | Example budget |
|---|---|
| Pre-hung solid-core door unit | $200 |
| Installation labor | $175 |
| Hardware and trim | $45 |
| Old door removal and disposal | $30 |
| Total | $450 |
What most people get wrong
- Buying a slab for a frame that is out of square — the slab saving is spent again on site fitting, and a pre-hung unit in a fresh frame is the cheaper sound opening.
- Ordering doors before measuring the openings — interior doors come in standard widths, but older homes hide non-standard openings, and a door bought an inch wrong is a return, not a trim.
- Comparing quotes without the hardware — knobs, hinges and casing are an 8–15% line, and a quote that excludes them is not cheaper, just shorter.
- Hanging a hollow-core door on a bathroom or bedroom for the saving — HomeGuide totals it at $120–$380 against $150–$680 for solid-core, and the sound difference is the thing you live with.
Costs in your city
Interior door pricing follows installer availability more than door prices — the units ship nationally, but the $120–$300 labor line in HomeGuide is local, and metros where carpenters are booked out price single-door call-outs at the top of it. Housing age travels with the city too: older stock brings settled, out-of-square openings and reframing ($110–$220 in HomeGuide) into ordinary swaps. The reliable lever everywhere is batching — several doors in one visit share the trip, so a whole-floor door refresh prices noticeably better per door than the same doors one at a time. Ask each bidder for their per-door rate at your door count, and whether hardware is included.
Frequently asked questions
How much does it cost to install an interior door?
About $300–$700 is the typical band on this page for one standard pre-hung door installed, with most projects landing around $450. HomeGuide's full replacement range runs $226–$824 including materials and labor, and EngineerFix prices a standard door at $438–$666 installed.
Is a pre-hung door or a slab door cheaper to install?
Pre-hung is usually the cheaper total when the frame is worn: HomeGuide prices pre-hung installation at $170–$470 with labor at $120–$170, because the door arrives fitted in its frame. A slab only wins when the existing frame is sound and square — the slab itself is cheaper, but the hinges and lock bore are cut on site, which is why its labor prices above the pre-hung rate.
How much is labor alone to hang an interior door?
About $100–$300 per door: EngineerFix puts labor alone at $100–$300, HomeGuide at $120–$300 for a replacement and $120–$170 for a pre-hung unit, which takes about 1–2 hours. Several doors in one visit price better per door than a single call-out.
How much does a pocket door cost to install?
About $500–$2,500 in HomeGuide, with Angi's national table at $800–$2,500. The door itself is ordinary; the money is the track and frame kit inside the wall, the drywall opened and repaired around it, and the trim — which is why pocket doors price as wall work, not door work.
Can I replace an interior door myself?
A like-for-like pre-hung or slab swap is one of the more realistic DIY jobs on this site, and the saving is the labor line — $100–$300 per door in the guides. The honest limits: a slab must be mortised and bored accurately or it will never latch cleanly, and pocket doors, reframing and resized openings are installer work in every guide's framing.
