The average cost to install an interior door is $791, or between $150 and $2,550, depending on the type of door, style, material, and hardware.
The average cost to install an interior door is $791, but your total can range between $361 and $1,221, depending on the type of door, material, quality, and more. Most interior door installations cost less than exterior door installations. Doors can often be an overlooked detail in your home decor, but the right door can set the style of a room. This guide breaks down interior door installation costs and what you should consider to get an accurate estimate.
The cost of installing an interior door depends on quite a few factors, including the type of door, size, labor, and hardware.
The type of door you choose—and there are plenty of interior door design ideas to consider—will greatly affect your interior door pricing. A simple bifold closet door costs $100 to $300 to install, while something more complicated, such as a pocket door, could run you as much as $2,500. The more complicated the installation and opening mechanism, the more your interior door will cost to install.
The average cost to install a slab door is $300 to $500, but installing a pre-hung door is more costly. When choosing between a slab or pre-hung door, there are differences to consider beyond the price. Pre-hung doors are easier to DIY, and you’ll have to shim the frame. Slab doors come in more sizes and don’t require installing a new frame.
Larger doors not only cost more for the materials—sometimes coming out to double the price—but also for the labor, as more work is involved in maneuvering your door into place and adjusting the door in your wall opening.
The door’s various components and materials reflect the overall installation price, as some doors are more expensive than others. For example, a solid wood door costs more than a similarly sized hollow-core door, and a metal or mirrored door will top the charts in terms of price by size. The table below includes some common door materials and related price ranges.
| Door Material Type | Average Cost Range |
|---|---|
| Hollow core | $30–$400 |
| Solid core | $70–$500 |
| Solid wood | $160–$590 |
| Aluminum | $300–$2,000 |
| Mirrored sliding door | $200–$2,300 |
The trim, or casing, sheaths the space between the frame and drywall, giving your newly installed door a complete, finished appearance. Installing trim costs about $0.50 to $1.50 per linear foot. If you opt for a high-end wood trim or decorative trim to match the rest of the trim in your home, you might pay a little more, sometimes up to $5 per linear foot.
Hinges are around $3 each, though fancier models can run into the double digits. Locks and doorknobs fall into the $20 to $200 range, with the higher end representing more technologically advanced keyed and coded locks for rooms you need to keep secure. A basic knob for an interior door costs around $20 to $40, and hinges will total between $8 and $50 per door.
The cost of resizing your doorframe depends on the size and location of the door and your new frame size. Professional door reframers charge $40 to $75 per hour, with drywall installation and prep costing $1.50 per square foot. The table below shows related costs.
| Resizing or Reframing a Doorframe | Average Cost Range |
|---|---|
| Hiring an electrician to relocate wires | $75–$100 per hour |
| Hiring a plumber to relocate pipes | $45–$200 per hour |
| Replacing a standard wood doorframe | $220–$370 |
| Widening the doorway | $300–$2,500 |
Opening up a wall can be very challenging. First, we check the ceiling and floor joists and whether a support beam is needed. If there’s a second floor, we open the wall to look for wiring, plumbing, or heating. Figuring out where to move these can dramatically increase costs.
Painting your door and frame to match your other doors is a budget-friendly way to breathe new life into your interior design. This process costs $75 to $150, depending on the door size, material, and the number of coats involved. Changing from a dark to a light color, for instance, costs more than swapping to a similar color due to the number of coats required.
Doing this work yourself is an easy DIY project that can save you money on your door installation cost.
Glass paneling, carved wood features, or special finishing all add to the project cost, as these tasks require purpose-built and often handcrafted components. These costs depend on the size and type of glass panel and the complexity of your desired accents. Going for these add-ons starts at around $50 and can balloon up to $500 or more per door for unique and complex accent designs.
Approximately 50% of your total door installation cost will go toward labor, with the other half going toward the replacement door and other materials. Removing an existing door and installing a new one should take a professional two to three hours, which will total around $350.
The labor cost to install an interior door can climb to $1,500 or more if you need your wall opening adjusted or if you want add-ons, like custom trim and glass installation.
If you’re handy and know how to install an interior door yourself, you can save on labor expenses. However, interior and exterior door installation is notoriously complicated, so if you don’t have experience, consider calling a door installer to get the job done.
The primary factor determining the material cost associated with having an interior door installed is the door style. For example, installing a high-end pocket door will cost more than a single or double bifold door because the materials cost more and the process involves more labor.
| Door Style | Average Installation Cost |
|---|---|
| Bifold | $100–$300 |
| $800–$2,500 | |
| French | $600–$6,000 |
| Sliding bypass | $250–$500 |
| Barn | $200–$2,500 |
| Saloon | $100–$300 |
| Murphy | $500 |
| Louver | $250–450 |
Bifolds have two or more hinged panels running on tracks. When opened, they fold in half, which can be a space-saver. A single bifold door costs between $35 and $60, while a double bifold will run you $45 to $70. The cost to install this style, including labor, is $100 to $300 per door.
Like bifolds, pocket doors are space-savers. These doors slide into the wall rather than opening into your living space. They’re labor-intensive and more expensive to install. Labor costs for installing pocket doors range from $800 to $2,500 per door.
French doors have several glass panels, usually in pairs. When opened simultaneously, they create a wide, dramatic opening and are common in dining and living rooms. Traditional French doors are hinged, but some models are single doors or sliding doors. The labor costs to install French doors total $250 to $500 per door.
Sliding bypass doors consist of two door panels on parallel tracks or one sliding door and a fixed panel. In either scenario, one door can pass the other via the tracks, making sliding doors a solid pick if you need to install a door over a large area but can’t accommodate French doors. Expect to pay $250 to $500 for the labor to install sliding bypass doors.
A kind of sliding door, barn doors have a visible track and are known for their rustic, farmhouse look. They’re most commonly made of wood but are available in other materials, like steel. Installing an interior barn door costs an average of $200 to $2,500, with high-quality, ornate, and hardwood barn doors on the higher end of the range.
Saloon, or swinging cafe doors, have a pivot hinge that allows the door to swing forward and backward. The materials for these doors are budget-friendly. Installing a saloon door costs about $100 to $300.
Murphy doors add a bit of mystery to your home, as they’re “secret” doors and often double as bookcases. In addition to adding an air of intrigue, they provide useful storage space while hiding an entryway to another room, which might be one where you keep valuables. It costs around $500 to install a Murphy door in your home.
Louver doors have horizontal slats that cover part or all of the door face. The slats let air through, meaning they won’t provide much security or privacy. For this reason, they’re considered interior doors only—as closet doors, statement sliding doors between a bedroom and bathroom, and doors to laundry or storage spaces that benefit from air circulation and venting. Expect to pay $250 to $400 to install louver doors, depending on the job's location, size, and complexity.
Interior doors, like any other building material in your home, may require ongoing maintenance and repairs, and it’s useful to think about these long-term costs when deciding on a door.
If you’re replacing a pre-existing door, that old door needs to go. Some door installers remove the old door as part of the interior door replacement costs, while others charge an additional removal fee. The costs depend on how large the door is and how difficult it is to get it out of the house. Additionally, the cost increases if you remove the frame and the door.
Prices range from $20 to $50 for this aspect of the job, and you may pay a little more if your installer charges you dumping fees.
Maintaining your interior doors may cost you next to nothing or an average of $100 every few years. Maintenance costs depend on the type of door you have.
For example, a solid wood door that’s painted or stained should get a new coat of finish every two to three years, which costs around $100 each time you have a professional do the work for you. You can also do it yourself for an average of $10 each time you need to refinish the door.
As you can imagine, some door styles require no ongoing maintenance. A swinging aluminum door or a sliding mirror door may need a little lubrication on the moving parts every now and then, but this is a simple DIY job with a negligible cost over time.
Most interior doors see a lot of use and are exposed to a lot of traffic, so they’re prone to damage. The cost to repair a door varies between $50 and $700, depending on the type of door and the extent of the damage.
Fixing a small dent in a solid wood door might cost around $50, patching a hole in a hollow core door should average about $100 to fix, and repairing broken glass in a French door could cost a few hundred dollars.
The last long-term cost you’ll need to consider when installing a door is the replacement cost. Of course, if a door is more expensive to install—like a French door or a pocket door—the replacement cost will also be higher.
However, consider the door’s durability and expected life span. While a hollow-core door costs about half as much as a solid wood door, the latter will last twice as long. You’ll pay more for certain types of doors, but you’ll get a greater value when factoring in their longevity.
High-quality doors can increase your home's resale value. If you plan to sell your home in the near future, a premium door material like solid wood or steel can make a positive impression on potential buyers.
You’ll only pay for the cost of the door itself, which means you’ll save around $350 if you DIY your interior door installation. This comes out to a savings of $40 to $90 per hour in labor fees. You should opt for light wood designs or pre-hung doors, which make for relatively easy installations.
In most cases, it’s best to call a door installer near you to set up your interior door. Improper installation could cause uneven framing, damaged trim, or a door that won’t latch or swing properly. This is especially true if you want a slab door instead of a pre-hung door or if you’re working with French doors, large doors, or any door that contains a mirror or glass.
The same goes for adding unique decorative elements to your door or widening the doorway.
Money-saving measures are always appreciated if you’re outfitting an entire home with new doors or operating on a strict budget. Here are some tips to save money when installing an interior door.
Go for simple designs and inexpensive materials: Hollow-core doors with simple designs and affordable hardware are easier on the bank account than solid-core doors with all the bells and whistles.
Comparison shop: To that end, don’t just scoop up the first door you find, even if it’s in your price range. Do some comparison shopping to find deals, as many retailers offer steep discounts on discontinued styles.
Use the pre-existing frame: The frame is one of the pricier components in this type of work. Buy a new door that fits into the current frame as long as the hardware is still in good shape.
Limit customization: All of those unique add-ons, like accents and glass panels, certainly increase the aesthetic splendor of your entryway—but they also increase the installation cost. Limit complex customization options unless absolutely necessary.

Replacing an interior door takes two to five hours to install, depending on the complexity of the design and the materials involved. Replacing a standard door with a pre-hung door will take around two hours, whereas replacing a large double French door will likely push the installation toward that five-hour mark. Replacing an exterior door takes a bit longer, about five to seven hours. Exterior doors require caulking, flashing, and weatherproofing steps, which increase the installation time.
So long as the frame is in good shape, you can replace an interior door without even touching the frame. This is the preferred option for homeowners looking to save money, as removing and replacing the old frame is a major cost factor with this type of job. Just make sure the new door fits the old frame without requiring too much work, and purchase a slab door without a new frame rather than a pre-hung door, which includes a frame.
The most common size for an interior door is 80 inches tall and 28 to 32 inches wide. However, a standard interior door can measure anywhere from 24 to 36 inches wide, depending on its intended use and the available space. According to most building codes in the U.S., a door must be at least 80 inches tall and 24 inches wide.
