How Much Does It Cost to Install Interior Doors? [2025 Data]

The average cost to install an interior door is $796, with most homeowners paying between $362 and $1,232. Your total cost will depend on factors like the door type, material quality, and installation method. While interior doors might seem like a minor detail, choosing the right one can enhance your home's style and functionality. This guide breaks down interior door installation costs and what to consider to get the most value for your investment.

New Interior Door Prices

Interior doors cost anywhere from $30 for basic hollow core styles up to $2,300 or more for high-end sliding options. Since labor costs are relatively low, the door you choose will have the biggest impact on your budget. Doors come in various materials, qualities, and designs—from budget-friendly hollow core to solid composite or premium wood options.

Hollow vs. Solid Core Composite Doors

Hollow core is the most budget-friendly type ranging from $30 to $400 each, though most pay in the range of $50 to $150. These typically have a honeycomb of cardboard slats with thin wood veneer faces. They work well in areas where sound transfer isn’t a problem, like a closet or pantry.

Solid core ranges from $70 to $250, with higher-end models costing $500 or more. This door construction consists of wood particles and glue or foam. These doors are an excellent choice for private rooms, such as bedrooms, bathrooms, home theaters, or offices. "Solid core" is not to be confused with solid wood.

Solid Wood

Solid wood doors come in a variety of styles, including slab or pre-hung, and often with glass inserts. Premium pre-hung wood runs between $160 to $590 or more.

Aluminum

Most aluminum interior doors, typically sliding or bifold types for wardrobes, cost $300 to $2,000 on average. Aluminum provides a high-end finish and is durable, with many aluminum interior doors lasting between 20 to 25 years when well-maintained.

Glass and Other Accents

Glass and other accent installations start at $50 and can go up to $500 or more per door, depending on the style and finish.

Pre-Hung vs. Slab Door Installation Costs

Pre-hung doors are popular because they're convenient and easy to install, but slab doors cost less. Think about what's most important for your project—convenience or cost-savings—as you plan your budget.

Pre-Hung Doors

Pre-hung interior doors come complete with a casing that fits into the space where the previous one stood, and these sets range from $60 to $1,000 or more, depending on the chosen material and accents.

Slab Doors

The average cost to purchase and install a slab door is $300 to $500, including materials and labor. The term “slab door” refers to a door without a frame or hardware. It can come pre-drilled but typically needs drilling for the knobs and hinges.

Cost to Install Frame, Trim, and Hardware

When budgeting for your door installation, remember that the door itself isn't the only expense. You'll also need to consider the costs of the frame, trim, and hardware like hinges and doorknobs, plus any labor costs if you're hiring a pro.

Frame

A door frame averages from $220 to $370. This price range does not include the rough frame or the 2-by-4-inch posts that make up the wall's structure. Instead, this is the casement that covers the rough frame, provides a place to secure the hinges and latch, and includes the doorstop.

Trim

Trim costs $0.50 to $1.50 per linear foot, potentially up to $5 per linear foot for high-end or decorative trim. This project usually comes out to $20 to $100 per door including materials and labor, depending on the type of trim used. Trim refers to the boards that cover the gap between the frame and drywall to give the wall opening a finished look.

Hinges and Hardware

Hinges run about $3 each for standard hinges, with total hinge costs between $8 and $50 per door, depending on the type. Locks and knobs run anywhere from $20 to $200 for keyed and coded locks. However, interior doors typically only require basic knobs, which cost around $20 to $40.

Average Cost to Hang an Internal Door by Type

Internal doors run an average of $750 with a range of $150 to $2,000, including materials, labor, and equipment. Distinct types all serve unique purposes and offer specific design and functional benefits. The type that homeowners choose and the materials all have a direct impact on the final price of this project.

Traditional Doors

Traditional composite wood interior doors cost between $50 to $600 on average, making them one of the most affordable options. The size of the door impacts the overall price, as well as if the door is hollow or solid.

Pocket Doors

Pocket door installation costs between $800 and $2,500 per door. Pocket doors are excellent for a closet or other tight spaces. This style is much easier to add to an addition, remodel, or new construction because the installation requires open walls free of wires and pipes. These doors slide into a hollow area of the wall along tracks on either end.

French Doors

Priced based on the intricacy of the glass panels and the quality of the wood, French doors cost between $600 and $6,000.

French refers to any unit, whether interior or exterior, with windows that extend throughout the whole frame. They’re also usually, though not exclusively, found in pairs like with many patio doors costing an average of $2,500.

Sliding Doors

Expect to pay $250 to $500 for the labor to install sliding bypass doors. Including materials, the total cost can range from $400 to $4,500, with most homeowners paying around $1,850. Although they’re popular as an exterior entry to a patio or deck, they make great additions inside the home to physically separate spaces in an open-concept layout.

Single and Double Bifold Doors

Total installation costs for bifold doors range from $100 to $300 per door, including materials and labor. These doors come in single and double designs, depending on the size of the opening they conceal. Depending on style and material, bifold doors can cost more, especially for high-end models.

Often found concealing closets or small workspaces, bifolds consist of hinged panels running on a set of tracks embedded in the casing and fold in half when opened.

Barn Doors

Barn doors cost anywhere from $200 to $2,500. The biggest price variables are the material, the number you'd like installed, and labor. If you are replacing a traditional door and frame, the newly exposed structure behind the trim will need to be finished, adding drywall prep and painting costs to your project total.

For materials, wood is the most common choice. You’ll need stain or paint to match existing trim or woodwork in your home. Barn doors have become increasingly popular and may increase your home's value to more than 10% above asking price.

Saloon Doors

Total cost for installing saloon doors ranges from $100 to $300 for standard installations, noting that more detailed or customized designs may cost $500 or more. The material used to construct a set of saloon doors, the thickness of that material, and the intricacy of the design affect the ultimate price of this uncommon option.

Murphy Doors

The cost to install a Murphy door is around $500. These are the "hidden bookcase" style. It’s essentially a solid core bookcase that swings in a frame the same as a standard door. A Murphy interior door provides usable storage space while concealing the entry to another room.

Cost to Replace Interior Doors

When replacing a door, in addition to the interior door replacement cost and framing, account for the removal and disposal fees. Removing the existing door and installing a new one typically takes about 2 to 3 hours and costs around $350 in labor.

Removal and disposal costs between $20 to $50, possibly more if the installer charges dumping fees. If your old doors are undamaged, consider donating them for a tax deduction or negotiating with the contractor for a reduction in installation pricing.

Cost of Replacing a Door Frame and Trim

Door frames cost between $220 and $370 with installation, and professional reframers charge $40 to $75 per hour. Expect to pay an additional $0.50 to $1.50 per linear foot for the cost of trim. This is only a 2- to 3-hour project for an experienced finish carpenter near you; however, it is also a fairly doable DIY project for homeowners with some carpentry experience.

Knobs and Hinges

Besides the $20 to $200 you’ll spend on the hardware itself, the job will take about an hour or at least $50 in labor. More likely, a contractor or locksmith will charge a minimal fee for the first hour of travel. Either way, expect to pay an additional $75 to $150.

Maintenance and Common Repairs

Most homeowners spend between $50 and $700 on door repairs, depending on the damage. Fixing a small dent in a solid wood door might cost around $50, patching a hole in a hollow core door averages $100, and repairing broken glass in a French door can be a few hundred dollars. Frame repairs can be as simple as a fresh coat of paint or might require partial removal and replacement. To keep your doors looking their best, plan for basic maintenance and repairs over time.

These jobs include projects as simple as greasing the hinges or installing stops to keep walls safe. In addition, repainting gives your doors an updated look and adds value and interest to your home. For example, pre-primed varieties are easy to update with coordinating paint colors that bring a room together.

Hollow Core Repairs vs. Replacement

One frequent problem that homeowners encounter when they opt for hollow core styles is important to note. Although they are much less expensive than solid wood, the cost savings may not last.

As the name indicates, their hollow nature makes them susceptible to accidental damage like poorly judged clearances when moving furniture. Sometimes it is possible to patch the smaller holes that appear. However, replacement is more often ideal for the sake of durability.

DIY Interior Door Installation vs. Hiring a Pro

While DIY-ing your interior door installation might seem tempting, hiring a professional door installer is often the better choice for a hassle-free experience. With labor costs around $350 for removing an old door and installing a new one, it’s a worthwhile investment. A pro will ensure your doors are well-balanced, swing evenly, and latch properly. Plus, they can spot any issues with the framing or electrical work that you might miss.

DIY Considerations

Replacing an existing door can be a manageable project for an intermediate to advanced DIYer. Typically, it takes about two to five hours—around two hours for a pre-hung door and up to five hours for larger doors like double French doors. If you're new to this, it might take longer, and hiring a pro could be a smart move. You could even have a pro help with the first door while you learn the ropes for future projects. Door installation requires skill, attention to detail, and patience, so getting guidance can make all the difference.

Aside from the need for a basic toolbox and power tools, such as a miter saw and drill, this project is rather affordable. The only materials needed aside from the door and its hardware cost less than $25.

Avoid some common DIY pitfalls, including:

• Uneven framing: Leads to improper closure. In extreme cases, it won’t close at all, requiring a complete reinstall.

• Ruined trim: Miter cuts on trim and incorrect measurements ruin trim. Having a professional finish carpenter install the finishing touches leaves a professional-looking door.

• Won’t latch: Not leveling the floor or frame prior to installation can lead to unmatched latch and hole placement. This requires re-drilling the holes or re-leveling the framing. Reframing runs $250 or more plus you lose the investment in your initial framing job.
