How Much Does It Cost To Install An Interior Door?

Cost to replace interior door

The cost to replace an interior door will be largely dependent on the size of the door. Standard doors are 80 inches high, and the widths vary. Closet doors are narrower than the standard 30 to 36-inch doors. Older homes tend to have smaller doors, while many modern homes have wider doors to allow for easier maneuverability. If you’re installing a new door for an elderly person or someone who needs assistance, a wider door will make things easier. Doors come in widths of 24, 28, 30, 32, and 36 inches.

Labor cost to install an interior door

Prepare to pay between $40 and $90 per labor hour to install your new interior door, with the average typically costing around $70 per hour. For most installations, it should take between three and five hours total to complete the job. A pre-hung door will take less time than a complete replacement which includes installing a new door frame. Slab doors are another alternative that involves creating a frame for a slab-style door on site.

Cost factors for installing a new interior door

Once you know what type and size of door you want to install, there are a few other factors that will determine your interior door replacement cost.

Frame

Some interior doors will come pre-framed, but if your door does not include a frame, you’ll need to buy one to provide support and a place for the door to hang on the wall. Door frames average between $150 and $300.

Trim

Trim is what covers the space between the wall and the door frame, covering the gap and providing a clean finished look. Trim is $2 to $3 per linear foot.

Hinges & hardware

Many doors will come with hinges, but if yours doesn’t or if you want to upgrade, you can expect to pay anywhere from $2.50 for a standard hinge, up to $10 or more. A doorknob and lock set will run you anywhere from $20 to $200, while a basic knob set is $20 to $40.

Before you commit to one contractor, make sure you get at least three quotes for your interior door installation project. Be clear on what’s included in the quote and if you need to purchase things like hinges, knobs, and locks separately, so there are no surprises when it comes to the cost to install an interior door.

Interior door types and pricing

In addition to the size factoring into the price of interior doors, you’ll need to consider the style of door you want to install. Different types of doors will work best in certain spaces. Here are the varying styles and where they’ll work best in your home:

Slab doors

A slab door is one of the most basic types of door you can purchase since they come without the frame or hardware. Some slab doors will have pre-drilled holes for door knobs and hinges, and others will be blank, requiring a contractor to drill holes.

Flush door

Flush doors are a simple and inexpensive option. Many modern standard interior doors are flush doors. When the door is closed, it sits flush with the door frame. Prices on flush doors can range from $20 to $200.

Pivot door

Pivot doors are an interesting design option since they have a single hinge in the center and can be opened from either side. A pivot door requires a larger space since you can enter from either side of the hinge. It works best in kitchens, but not as well in bathrooms or closets because of its larger size.

Panel door

Panel doors are frequently seen in home interiors. The name refers to the inset panels that are placed on the face of the door for added visual interest. Panel doors are between $25 and $500 on average, and are one of the most popular choices. 

Pocket door

Pocket doors are a great option if you need to save space. This style of door does not swing open but rather slides inside the wall when open. Pocket doors are more difficult to install and repair, but they’re great for small spaces. You can expect to pay between $120 and $1,000 for a pocket door.

French door

French doors are a high-end addition to your home design, providing the option to open one or both doors. French doors are especially striking on patios, where their glass panels create a beautiful visual to the outdoors, whether they’re open or closed. 

Dutch door

Dutch doors are divided horizontally in the middle, giving you the option to open the top half of the door and leave the bottom half closed, or open the full door as normal. 

Roller door

Roller doors function like garage doors, rolling upwards on a vertical track across the ceiling when they’re open. Great for industrial-style spaces, roller doors are a more expensive option that takes specialized maintenance, starting at $500 and upwards.

Barn door

Barn doors hang from a metal track and roll horizontally. They’re a perfect addition to a farmhouse design, though they do require an equal amount of wall space as the width of the door in order for it to roll open. Barn doors are variable in cost, averaging anywhere from $150 to $2,000.

Sliding door

Sliding doors are perfect for wider thresholds where a barn door or French doors don’t work. Sliding doors have two panels that pass each other on a sliding track, allowing for either side to be opened. The average sliding doors cost $500 per set.

Bifold door

Bifold doors are most commonly used in closets, running on a track and hinging in the middle to fold in half when open. The cost for these interior doors averages from $100 to $2,000.

Saloon door

Saloon doors, also called cafe doors or pantry doors, only partially cover the opening from midway up. Seen often in old western movies, these doors swing open to meet in the middle. You can expect to pay between $150 to $500 or more for a pair of saloon doors. 

Murphy door

Murphy doors are essentially hidden doors. This type of door resembles a bookcase on the outside and is perfect for disguising panic rooms or safes. Murphy doors can cost anywhere from $600 to $4,500 for the door alone.

Interior door material

Interior doors come in a variety of materials, each with different price points. Below is a breakdown of each type and what you can expect to pay on average.

• Solid wood – Average cost of $150 to $850
• Hollow-core – Average cost of $30 to $240
• Solid-core (composite material)– Average cost of $60 to $330
• Aluminum – Average cost of $40 to $500
• Glass – Average cost of $170 to $1,300
• MDF – Average cost of $30 to $400

Reframing interior door cost

Generally, when you replace an interior door, you replace the frame as well. Your contractor will be able to do the removal and disposal of the old door for you. Disposal fees are between $25 and $50, depending on your location. In addition, your contractor may negotiate a lower price for the removal if they can keep your old door to use in a future project, resulting in a lower cost to install an interior door.

Extra costs could include replacing the door frame, which you can expect to be about $250, plus $2 to $3 per linear foot for trim. After that, you’ll want to make sure you have the hardware, like hinges and doorknobs, which you can install yourself. These cost anywhere from $5 to $150, or have a pro locksmith do it for an extra $75 to $100.

How to install a prehung door?

If your interior door installation is simple and you don’t have to replace the frame, you can tackle this as a DIY project. Similarly, if your new door is pre-hung, the installation process is fairly straightforward. First, trim the door jamb and frame to fit your opening, then use cleats to hold the frame in place as you nail it into the surrounding 2x4s. Then use shims to level the door and frame in the opening, and nail the frame in once it’s all level. After the installation is done, finish your new interior door with trim that matches your design. 

This can be a complicated process, so you may want to hire a professional. You don’t need to pay for a carpenter to do this. Most local handymen will be able to do the job in under two hours for between $316 and $488, on average.
