Quick Answer: Average Cost to Replace an Interior Door
The cost to replace an interior door typically falls between $150 and $800 for a basic slab replacement using the existing frame. A full door-and-frame (pre-hung) installation averages $300 to $1,200, including professional labor. Nationwide, most homeowners spend around $400–$900 per door for a complete replacement with mid-grade materials.
Replacing an interior door is one of the most common home improvement projects in the United States. Whether you are upgrading an old, worn-out bedroom door or swapping hollow-core slabs for solid wood throughout a hallway, the total cost to replace interior door units depends on material choice, frame condition, labor rates in your area, and whether you need new hardware. This guide breaks down real-world pricing so you can budget with confidence.
Across the US, the average cost to replace interior door and frame as a complete unit runs higher than a slab-only swap. Many homeowners are surprised to learn that the labor cost to replace interior door components often exceeds the price of the door itself, especially when the existing jamb or trim needs work. Below, we cover every component—slab, frame, hinges, hardware, and trim—so nothing is overlooked.
What Determines the Cost to Replace Interior Door Units?
Several variables influence the final price tag. Understanding these helps you avoid overspending or underestimating your budget:
- Door material: Hollow-core molded doors start as low as $40–$80, while solid wood panels can exceed $400 each.
- Frame condition: Keeping the existing frame saves $100–$300 in labor and materials. A damaged jamb means you'll need a pre-hung door.
- Hardware scope: The cost to replace interior door hardware—knobs, hinges, strike plates—adds $20–$100+ per door depending on finish quality.
- Labor rates: The labor cost to replace interior door work varies by region, from roughly $60/hour in the Midwest to $100+/hour in coastal metro areas.
- Trim and casing: If the existing trim breaks during removal or doesn't match the new door style, replacing it adds $50–$200 per opening.
Cost Breakdown: Interior Door Replacement by Component
The table below shows typical US price ranges for each part of an interior door replacement project. Use these figures as a baseline when gathering estimates from local contractors.
| Component / Service | Average Cost | Low End | High End | Notes |
|---|---|---|---|---|
| Door slab – hollow core | $50–$150 | $30 | $200 | Material only; standard sizes |
| Door slab – solid wood | $150–$400 | $100 | $600+ | Material only; oak, maple, pine |
| Pre-hung door – hollow core | $150–$300 | $100 | $400 | Includes frame and slab |
| Pre-hung door – solid wood | $300–$700 | $200 | $1,000+ | Includes frame and slab |
| Labor – slab replacement only | $100–$300 | $75 | $500 | 1–3 hours; existing frame reused |
| Labor – full frame replacement | $200–$500 | $150 | $800 | 2–5 hours; includes demolition |
| Hardware – knobs & hinges | $20–$100 | $10 | $200+ | Finish and brand dependent |
| Trim & casing (per door) | $50–$200 | $30 | $400 | Includes painting or staining |
Costs are national averages and vary by region, provider, and project complexity.
Slab-Only vs. Full Frame Replacement
If your existing door frame is square, undamaged, and in good condition, you can often replace just the door slab. This is the most affordable route: the cost to replace interior door slab ranges from $150 to $500 installed when using a hollow-core or lightweight solid panel. The installer trims the new slab to fit the old jamb, mortises hinge pockets, and drills the knob hole—work that takes about 1–2 hours for an experienced carpenter.
When the frame is warped, cracked, or out of square, you'll need a pre-hung door. The cost to replace interior door and frame as a complete unit runs higher because it involves demo, shimming, leveling, re-casing, and often patching drywall around the opening. In cities like Seattle, Boston, and San Francisco, full replacements frequently hit $900–$1,200 per door, while the same job in Dallas, Indianapolis, or Kansas City might total $500–$750.
Labor Cost to Replace Interior Door: What Installers Charge
The labor cost to replace interior door projects depends heavily on local market rates. Most finish carpenters and handymen charge between $60 and $110 per hour. A straightforward slab swap in an existing frame takes 1–2 hours. Installing a pre-hung door with new trim and hardware can take 3–5 hours, especially in older homes where walls are rarely perfectly plumb.
Some contractors quote a flat per-door rate rather than hourly billing. Nationally, flat-rate labor for a single interior door replacement averages:
- Slab-only replacement: $100–$250 per door
- Pre-hung door with trim: $250–$500 per door
- Multiple doors (bulk pricing): $80–$180 per door for 5+ units
Cost to Replace Interior Door Hardware, Hinges, and Knobs
Hardware is often overlooked in budgeting but makes a visible difference in the final result. The cost to replace interior door hardware—including knobs, lever handles, hinges, and strike plates—runs from as little as $15 per door for basic builder-grade sets to $150+ for premium finishes like brushed nickel, matte black, or oil-rubbed bronze. If you're asking "is it worth the cost to replace interior door knobs?" the answer is usually yes when the existing hardware is tarnished, loose, or stylistically dated, because fresh hardware instantly modernizes the look without requiring a full door swap.
The cost to replace interior door hinges specifically is modest—typically $5–$20 per hinge—but replacing all three hinges per door adds up if you are doing a whole house. Many pre-hung doors include basic hinges, so factor this in when comparing slab-only versus pre-hung pricing.
Regional Pricing: US City Examples
Where you live significantly affects the total bill. Here are real-world examples based on contractor surveys and publicly reported market data:
- New York, NY: $500–$1,100 per pre-hung door (high labor rates, older building quirks)
- Chicago, IL: $400–$900 per door (moderate labor, competitive contractor market)
- Atlanta, GA: $300–$700 per door (lower labor costs, newer housing stock)
- Phoenix, AZ: $280–$650 per door (competitive rates, abundant contractors)
- Los Angeles, CA: $450–$1,050 per door (high cost of living drives labor up)
These ranges assume a mid-grade pre-hung interior door with standard trim. Custom wood species, French doors, or pocket door retrofits push pricing significantly higher.
Practical Tips and Common Mistakes
Tips to Keep Costs Reasonable
- Measure twice, buy once: Confirm rough opening dimensions before purchasing. Standard interior doors are 24, 28, 30, 32, and 36 inches wide—but older homes may have non-standard sizes that require custom orders.
- Reuse the existing frame when possible: If the jamb is solid and square, a slab-only replacement slashes $150–$400 off the total.
- Bundle multiple doors: Replacing 5+ interior doors at once often earns a bulk discount from contractors and suppliers.
- Choose paint-grade over stain-grade: Paint-grade doors cost 30–50% less than stain-grade wood with comparable durability.
Mistakes to Avoid
- Ignoring the swing direction: Ordering a left-hand door when you need a right-hand one (or vice versa) causes delays and restocking fees.
- Skipping the door stop and weatherstripping: Interior doors benefit from proper stops for sound reduction and light control—don't overlook this small but important detail.
- Underestimating trim work: If the new door is slightly smaller than the old one, gaps around the casing require patching or wider trim, adding unexpected cost.
- Choosing the cheapest hollow-core door: Ultra-thin hollow doors dent easily and offer poor sound insulation. Spending an extra $30–$60 on a better slab often pays off within the first year of use.

Frequently Asked Questions
How much does it cost to replace an interior door and frame?
For a standard pre-hung interior door with professional installation, expect to pay between $300 and $1,200. The national average lands around $550–$800 for a mid-grade door with painted trim in a typical single-family home.
Can I replace just the door slab and keep the existing frame?
Yes, if the frame is structurally sound, level, and square. A slab-only replacement costs between $150 and $500 installed. This approach works well for closets, bedrooms, and hallways where the jamb is in good condition and you want to minimize disruption.
How much does labor cost to replace an interior door?
Labor alone typically ranges from $100 to $500 per door, depending on whether it's a simple slab swap or a full pre-hung installation with new trim. Hourly rates for finish carpenters span $60–$110 across most US markets.
What factors affect the cost to replace interior door hardware?
Hardware cost depends on finish (chrome is cheapest; matte black and oil-rubbed bronze cost more), brand, and whether you need knobs, levers, hinges, and strike plates. A full hardware set per door ranges from $15 to $200+.
Is it worth replacing interior doors before selling a home?
In many cases, yes. Fresh, modern interior doors improve perceived home value and can help a listing stand out. Focus on high-visibility areas like the entry-level hallway, master bedroom, and bathroom. Budget-friendly paint-grade pre-hung doors offer strong ROI without overspending.
How long does it take to replace an interior door?
A slab-only replacement typically takes 1–2 hours. A full pre-hung door with new trim and hardware can take 3–5 hours. Older homes with non-standard rough openings may require additional time for framing adjustments.
Do interior door replacements include trim and painting?
Not automatically. Many contractors quote door installation separately from trim work and painting. Always clarify whether painting or staining is included in the estimate. Unpainted primed doors need finishing, which adds $50–$150 per door if you hire a painter.
