Estimated Total Cost
Interior Door Installation Cost by Type
| Door Type | Materials | Installed (all-in) | Notes |
|---|---|---|---|
| Slab door (frame reused) | $50–$300 | $150–$500 | Cheapest option — only works if existing frame is square and undamaged |
| Pre-hung (new frame) | $100–$500 | $450–$1,000 | Most common replacement — frame, hinges, and door arrive as one unit |
| Bifold / closet | $50–$250 | $100–$400 | Simple track installation; hollow-core standard |
| Pocket door | $200–$800 | $500–$2,500 | Slides into wall — requires opening wall for track; most complex interior install |
| Barn / sliding door | $200–$1,000 | $400–$2,000 | Surface-mounted track — easier than pocket but needs clearance wall space |
| French doors (interior) | $400–$1,500 | $800–$3,000 | Double door; glass panels standard; requires wider rough opening |
Door Cost by Material
| Material | Door Cost (slab only) | Best For | Downside |
|---|---|---|---|
| Hollow-core | $30–$150 | Closets, low-traffic areas, rentals | Poor sound blocking; feels lightweight |
| Solid-core | $100–$400 | Bedrooms, offices, home theaters | Heavier — needs sturdy hinges |
| Solid wood | $200–$800 | High-end remodels, historic homes | Most expensive; can warp with humidity |
| MDF / composite | $80–$300 | Painted finishes, moisture-prone areas | Heavy; doesn't take stain well |
| Glass panel | $200–$1,200 | Home offices, living areas, studies | Privacy trade-off; more fragile |
What a Professional Quote Should Include
About 50% of total cost is labor, 50% materials. A complete quote covers:
- Door slab or pre-hung unit — the door itself, frame, and hinges if pre-hung
- Hardware — doorknobs, lever sets, or privacy locks ($20–$150). Often not included; ask explicitly
- Trim / casing — finishing the gap between frame and drywall ($0.50–$5/linear foot)
- Old door removal and disposal — $25–$75 per door; sometimes bundled
- Frame adjustment — shimming, planing if opening is out of square (+$50–$200)
⚠️ Get quotes for a slab vs. pre-hung separately. If your existing frame is square and undamaged, a slab replacement saves $100–$300 over a pre-hung unit for the same door. Ask your contractor to check the frame before assuming you need the full pre-hung package.
Labor Costs Explained
- Standard pre-hung interior door: 1–2 hours at $40–$90/hr = $100–$250 labor
- Pocket door: 4–8 hours — wall must be opened, track installed, then closed. Labor alone $300–$700
- Barn door: 2–4 hours — track mounting, door hanging, leveling = $150–$350 labor
- Multi-door projects: Most contractors discount 10–20% on 5+ doors installed in one visit — ask upfront
- Minimum service fee: Many contractors charge $200–$250 minimum call-out — installing multiple doors in one visit spreads that fixed cost

DIY vs. Professional: When Each Makes Sense
- DIY is reasonable for: Slab replacements in square, undamaged frames. Bifold closet doors. Basic hardware swaps. Saves $100–$300 per door on labor.
- Hire a pro for: Pocket doors (wall work required), any structural modification, out-of-square frames, barn door header installation, or 5+ doors where efficiency matters.
- The hidden DIY cost: A misaligned door that sticks, gaps, or doesn't latch costs more to fix than the original labor savings. If your floors or walls are even slightly unlevel, professional shimming pays for itself.
💡 Best time to install: bundle multiple doors. If you have more than 3 doors to replace, schedule them in a single visit. Most contractors discount 10–20% per door on multi-door projects, and you avoid paying the $200–$250 minimum service fee multiple times.

Frequently Asked Questions
How much does it cost to replace an interior door?
The national average is $798 installed, ranging from $362 to $1,233. A simple slab replacement (door only, existing frame) runs $150–$500. A pre-hung door with new frame costs $450–$1,000. Pocket and barn doors cost more due to hardware and framing complexity.
What's the difference between a slab door and a pre-hung door?
A slab door is just the door panel — no frame or hinges. It's cheaper ($50–$300) but only works if your existing frame is square and in good condition. A pre-hung door comes with frame, hinges, and sometimes hardware already attached. Pre-hung costs more upfront ($100–$500) but is the better choice if the existing frame is damaged, warped, or out of square.
How long does it take to install an interior door?
A standard pre-hung interior door takes 1–2 hours for an experienced carpenter. Bifold and slab replacements can be done in under an hour. Pocket doors take 4–8 hours due to wall work. Barn doors take 2–4 hours. Out-of-square frames or damaged framing add 1–3 hours to any project.
Should I use a hollow-core or solid-core interior door?
Use hollow-core for closets, utility rooms, and low-traffic areas where cost matters most ($30–$150 for the slab). Use solid-core for bedrooms, home offices, and bathrooms where sound blocking matters ($100–$400). The difference in installed cost is $100–$200 per door — worth it for any room where privacy or noise matters.
