Door configuration, frame condition, finish, hardware, and labor all stack onto that base price. A straightforward swap in a sound, square opening costs far less than installing a new or custom-sized unit that needs frame, trim, or wall modifications.
Many homeowners budget for the door and get surprised by everything else. This guide covers current US cost ranges, what drives the final price, what a real quote should include, and how to plan whether you're replacing one door or refreshing an entire house.
Key Takeaways
- Installed interior door projects typically run $362–$1,232, averaging around $797
- Replacing a door in an existing opening often costs $374–$697 including labor
- Price drivers include slab vs. pre-hung configuration, core material, custom sizing, finish, and frame condition
- Specialty installs like pocket, French, or glass-panel doors cost more due to added framing work
- Compare total scope and quality, not just the door's sticker price
How Much Does Interior Door Installation Cost?
There's no single national price for "interior door installation" because the phrase covers wildly different jobs. A basic slab swap, a complete pre-hung unit, a pocket door system, and a custom opening all carry different cost structures.
According to HomeAdvisor's 2025 guide, the overall average for interior door installation lands at $797, with a typical range of $362 to $1,232.
Fixr's January 2025 data puts installer labor at $44–$83 per hour. A new door in an existing opening typically runs $374–$697 including labor and materials.
Here's how common project types break down:
| Door type | Typical cost | What's included |
|---|---|---|
| Hollow-core door (product only) | $30–$150 (up to $400 premium) | Door only, per HomeAdvisor |
| Solid-core door (product only) | $70–$250 ($500+ premium models) | Door only, per HomeAdvisor |
| Slab, purchased and installed | $300–$500 | Door plus installation; no frame |
| Pre-hung set (product) | $60–$1,000+ | Frame, hinges, door |
| Bifold, installed | $100–$300 per door | Materials and labor included |
| Pocket door, installed | $800–$2,500 | Includes wall/track work |
| French doors, installed | $600–$6,000 | Wide range by size and glass |
| Bypass sliding, installed | $400–$4,500 | Labor alone runs $250–$500 |
A few assumptions matter here:
- A slab price does not include a frame, hinges, or hardware, while a pre-hung set does
- "Installed" figures from HomeAdvisor bundle materials and labor; door-only prices do not
Multi-door projects change the math. Mobilization, repeated measurement, and delivery costs get spread across more units, often lowering the per-door price compared to a single one-off replacement.
Key Factors That Affect Interior Door Installation Cost
Three broad categories determine your final number: the product you choose, the condition of your existing opening, and how complex the installation scope becomes.
Door Type and Configuration
Slab doors need on-site hinge, latch, and strike prep. Pre-hung units arrive with the frame and hinges already set, which simplifies fitting but costs more upfront.
Specialty configurations add further complexity:
- Pocket doors require wall cavity framing and track alignment
- French doors need matched panels and often custom hardware
- Barn doors rely on exposed rail hardware and wall reinforcement
- Frameless or concealed-hinge doors demand tighter tolerances and precise alignment
Core Construction and Material
Hollow-core doors are lighter, cheaper, and offer minimal sound control. Solid-core doors weigh more, resist warping better, and cost more to buy and handle.
Masonite's 2025 selection guide notes that solid-core doors contain roughly 70% more material than hollow-core versions, built for better resistance to warping, shrinking, and cracking. Veneer, laminate, and glass-heavy doors each carry their own pricing logic rather than fitting into one "custom" bucket, so price materials individually rather than guessing.
Size, Handing, and Customisation
Standard widths and heights keep costs predictable. Non-standard sizes, unusual jamb depths, or special swing clearances push manufacturing and installation costs higher.
Custom sizing isn't automatically wasteful spending. It can eliminate the need for wall framing changes in an existing home, even though the unit itself costs more to produce and deliver.
Frame, Opening, and Trim Condition
An out-of-square or damaged jamb often means frame repair or replacement before a new door goes in. A sound, square frame allows a simpler slab swap.
Watch for these scope items that add cost even on an "affordable" door:
- Casing and baseboard replacement
- Drywall repair around the opening
- Flooring transition adjustments
- Paint touch-ups after frame work
Installation Complexity and Site Conditions
Heavy solid-core or glass doors need more careful handling. Occupied homes, multiple floors, tight access, and protecting finished surfaces all add labor time.
Permits can apply if you widen an opening, alter a load-bearing wall, or install a fire-rated door, per the 2024 International Residential Code. Local requirements vary significantly, so check with your building department before any structural change.
Cost Breakdown of an Interior Door Installation
A reliable estimate separates the door system, labor and prep, finishing, and extras. One unexplained lump sum tells you nothing about where your money goes.
Door and Door-System Components
A complete system typically includes the door panel, frame or jamb, hinges, latch, strike plate, casing, and your chosen knob or lever. What's included depends on what you're buying:
- Slab only: door panel, sometimes pre-drilled for hardware
- Pre-hung unit: frame, hinges, and door together
- Complete kit: door, frame, moldings, hinges, handles, and seals in one package
Labor and Installation Preparation
Fixr reports installer labor at $44–$83 per hour, with typical installation taking one to three hours. HomeAdvisor estimates replacement labor at roughly $350 for a straightforward swap, calling labor about half of its average total project cost.
That labor typically covers:
- Measurement verification and old door removal
- Fitting, leveling, and shimming
- Hinge and latch alignment with final adjustment
Finishing, Trim, and Site Repairs
Many basic quotes exclude finishing work entirely. Painting, staining, caulking, and casing replacement often show up as separate line items.
HomeAdvisor lists trim installation at $20–$100 per door, or $0.50–$1.50 per linear foot. Confirm upfront whether your chosen door arrives factory-finished or needs on-site painting, since this distinction matters most with veneer and laminate products.
Delivery, Removal, and Other Potential Add-ons
Removal and disposal of an old door typically runs $20–$50, per HomeAdvisor. Add delivery fees, upgraded hardware, custom machining, and potential return visits for measurement errors.
Before signing anything, confirm in writing:
- Whether tax is included in the quoted total
- Warranty coverage and term on the door and labor
- Lead time for custom or special-order units
- Who corrects measurement or fit issues after installation
Lower-Cost vs Higher-Cost Interior Doors — What's the Difference?
Price differences go beyond appearance. Construction quality, sound control, dimensional accuracy, hardware grade, and installation tolerance all separate budget doors from premium ones.
Lower-cost options make sense for closets, low-traffic rooms, rental refreshes, or any space where basic privacy is the only requirement. Hollow-core, standard-sized, prefinished doors fit this category well.
Higher-cost options justify their price when design continuity, sound reduction, or a tailored fit actually matter. Solid-core, custom-sized, veneer, and glass-panel doors fall here.
Warranty terms offer a useful, verifiable proxy for durability expectations:
- JELD-WEN: 10 years on interior MDF doors, 5 years on other interior doors; skilled labor covered for one year
- Masonite: 7 years on solid-core slabs, 5 years on hollow-core slabs; labor, installation, and finishing excluded
A cheap product price can turn expensive fast. If a budget door needs extensive field trimming, new hardware, or frame repair, the "savings" disappear into labor and materials you didn't plan for.
How to Estimate the Right Budget and Avoid Surprises
Start with scope, not price. Define the number of doors, rooms involved, door type, finish preference, and whether each opening stays unchanged.
Measure before you quote. A basic inspection checklist should cover:
- Opening width and height
- Jamb depth and wall thickness
- Handing (swing direction) and clearance
- Floor height and casing condition
- Visible frame damage or warping
Request itemized quotes that separate product, delivery, labor, hardware, frame work, trim, finishing, removal, and disposal. A single bundled total makes comparison shopping nearly impossible.
A few practical ways to control cost without sacrificing fit:
- Group multiple doors into one order to spread mobilization costs
- Retain a serviceable frame instead of replacing it
- Use standard sizes where the opening allows
- Choose factory-finished products to skip on-site painting
This is where a complete-kit approach changes the math. European Style Doors supplies custom European-design doors through its Pavone line, manufactured in Los Angeles. The door, frame, moldings, hinges, handles, and seal arrive as one finished kit.
Extension pieces cover wall thicknesses from 4½ to 8 inches, and custom sizing is available without requiring wall modifications. Confirm product availability, delivery timing, and professional installation options for your project rather than assuming a fixed national price applies.
Professional installation is the safer call for custom doors, heavy solid-core units, pocket doors, concealed hardware, multi-room packages, and any opening that's damaged or out of square. A DIY mistake on a $150 hollow-core closet door is forgivable. The same mistake on a $2,000 custom glass-panel unit is not.
What Most People Miss When It Comes to Interior Door Installation Cost
A few recurring blind spots inflate budgets after the fact:
- Fixating on the advertised door price while overlooking labor minimums, delivery, hardware, casing, finishing, removal, and disposal
- Assuming a slab is automatically cheaper than a pre-hung unit without accounting for hinge mortising, latch prep, and frame condition
- Skipping finish confirmation before ordering, especially when matching several doors to existing millwork
- Dismissing custom sizing as unnecessary when it may actually prevent costly wall changes
- Confusing a basic bedroom swap with a specialty job involving pocket-door framing, glass, or concealed hinges
Each of these turns a "simple" project into a multi-visit job with unplanned costs.
Conclusion
Interior door installation cost varies with the door system, material, size, finish, frame condition, labor, and overall project scale. There's no single number that fits every home or every door.
An itemized quote, with every inclusion and exclusion spelled out, tells you far more than any average price online. Compare appearance, fit, durability, installation complexity, and long-term value together before committing to a door or a contractor.
Frequently Asked Questions
What is the average cost to install new interior doors?
HomeAdvisor's 2025 data puts the national average at $797, with a typical range of $362–$1,232 for installed projects. Fixr's separate estimate for replacing a door in an existing opening runs $374–$697, including labor and materials.
How much does it cost to install a pre-hung interior door?
A pre-hung set typically costs $60–$1,000+ for the product alone, depending on size and material. Frame condition, trim needs, and hardware upgrades all affect the final installed price.
Is it cheaper to install a slab door or a pre-hung door?
A slab door costs less upfront but needs on-site hinge and latch preparation, which adds labor time. A pre-hung unit costs more initially but simplifies fitting, so the cheaper option depends on your existing frame's condition.
What is included in an interior door installation quote?
Most quotes cover measurement, old door removal, fitting, hinge and hardware installation, and basic adjustment. Finishing, frame repairs, and trim replacement are often priced separately, so confirm these in writing.
How much does it cost to install a custom-sized interior door?
Custom manufacturing, measurement, delivery, finish, and machining all add to the base price compared to standard sizes. No single national range applies here since custom pricing depends heavily on the specific collection and complexity.
Should I hire a professional to install interior doors?
Simple replacements in sound, square openings can be reasonable DIY projects for experienced homeowners. Custom doors, heavy solid-core units, pocket doors, and frame-repair projects carry enough fit and finish risk to justify professional installation.
