How Much Does It Cost to Install Interior Doors?

New Interior Door Prices

Interior doors range from hollow core slab types starting at $30 and up to $4,500 or more for wood and glass French varieties.

Given the low rates for labor, remaining in budget usually has minstalore to do with the cost of the door than any other factor. All styles come in a variety of materials, qualities, and designs. Most notable are the hollow types versus solid doors consisting of composite or premium wood.

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 $150 to $1,000 or more though most fall in the $250 to $600 range.

*Costs for door only (no hardware or labor) for a standard single door at 1 3/8-inch thickness, 80 inches high, and between 24 and 36 inches wide.

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

Accents—such as the number and design of the panels, finishing and paint, carved wood features, and glass inserts—all increase prices, regardless of the type. For example, composite bifold models I with hollow cores sell for as low as $30 each. However, more ornate, glass-accented, solid bifold models retail for more than $500 each.

Pre-Hung vs. Slab Door Installation Costs

Many homeowners choose pre-hung doors because they’re convenient and easy to install. However, slab doors generally cost less than pre-hung options. Consider what’s more important to you personally as you budget for your project.

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.

In addition to the material prices, make sure to budget for the labor costs. Labor rates for this type of installation vary according to size:

Homeowners may increase the price of their installation with add-on services such as the following.

Slab Doors

A slab door usually costs less than a pre-hung door, running anywhere from $50 to $400 on average. 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

The door itself isn’t the only expense you’ll have to contend with when budgeting for door installation costs. The frame, trim, and associated hardware like hinges and doorknobs all cost extra and have their own associated labor costs if you hire a pro.

Frame

A door frame averages from $150 to $300. This 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$2 to $3 per linear foot, usually coming out to $40 to $60 per door including materials and labor. 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 $2.50 each with designer hardware sometimes exceeding $10. 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 $140 and $180 for a new build or addition. Installation in an existing room will run $600 to $1,000 or more.

Pocket doors are excellent for a closet or other tight spaces. Pocket styles are 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, basic interior French styles may cost as little as $200 each or as much as $4,000 or more. Installation costs are usually no different than those for pre-hung styles because they operate on the same frame-and-hinge design.

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

Sliding glass doors costbetween $400 and $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

Single bifold doors cost between $35 and $60 while a double bifold averages $45 to $70. They come in single and double designs, depending on the size of the opening they conceal. Depending on style and material, these doors are purchased individually for $30 to $500 or more. 

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 $150 to $4,000. 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

Basic slatted saloon doors retail for around $100 to $150, whereas more detailed, solid, or glass-accented pairs cost about $500 or more, especially if custom elements such as carved designs, raised panels, or iron accents are included. Installation usually costs $50 to $250. 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

Murphy doors range in cost from $700 to $2,500 depending on the size. 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. It will take an additional hour of labor to remove the existing door for an average of $50. Most disposal fees vary by location and usually cost an additional $25 to $50. 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 about $250 with installation, and expect to pay an additional $2 to $3 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 $10 to $150 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.

Interior Door Installation Labor Costs

The cost of labor to install an interior door runs between $40 and $90 per hour with an average rate of $70 per hour though it varies by geographical location. It takes 3 to 5 hours for most pros to finish the installation, so expect to pay around $120 to $450 in labor expenses per door.

Where to Buy Interior Doors

Buying new doors is as simple as heading down to a local home improvement warehouse or neighborhood hardware store. These retailers offer several styles from popular names such as:

• JELD-WEN: Available in a wide array of styles and most big box home improvement stores.

• Masonite: One of the top five manufacturers that creates an extremely wide range of door types and styles in MDF and wood.

• Sarto: Italian door company specializing in modern luxury designs.

• Anderson: Doing more than just windows, they create mid- to higher-end doors in both contemporary and modern styles.

• Pella: Also known for windows, Pella specializes in mid- to high-end exterior models, including wood, fiberglass, and steel. They also offer patio and entry doors.

To achieve a unique look, opt for custom cuts and styles. Whether you want French with carved glass, slab with detailed carvings, or doors made from rare wood, obtaining a custom design by a local carpenter or other craftsman allows you complete creative freedom. Other specialty installation services may use advanced technology, such as computerized measuring tools to design and laser-cut for an exact fit, saving you time during installation.

Maintenance and Common Repairs

Average door repairs cost$220, while frame repair can be a simple fix with some paint or require partial removal and replacement. Keeping a door looking its best usually means performing basic maintenance and repairs throughout its life.

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

It’s almost always a good idea to hire a contractor. Doors may seem easy, but there are many pitfalls to the installation.

DIY Considerations

Installing a door where one already exists is a straightforward home improvement project suited for the intermediate to advanced DIYer. Properly done, this project should take 2 to 3 hours for a pre-hung type and about 5 to 6 hours for a slab variety. 

If this is your first project, it can take longer and it would be best to hire a pro and learn from them. If you’re looking to save money on labor and have multiple doors to install, hire a pro to assist you with the first door. Installation, while it may seem easy, requires a high level of skill, attention to detail, and patience. Learning from a pro is the best way to learn for future DIY installations.

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.

Benefits of Hiring a Pro

In most cases, hiring a door installer near you is the better solution. The labor costs only end up being in the $100 to $300 range and if you have multiple doors, expect to be closer to $100 to $150 per door. And it can easily pay off. You’ll have doors that are well balanced, swing evenly, and latch properly. A professional will also be able to spot any problems in the rough framing or the need for electrical work in the case of new installations.
