What is the Average Cost to Install Interior Door?

Interior doors provide your home privacy and safety, but they can also be a stylish addition to your extension when you build it. No matter what the cost to install interior doors ends up being, you can use them for privacy in your bathroom, for passage from one room to the other, or to disguise the interior of a storeroom or closet. You can choose from a huge range of sizes, types, and materials when you start to shop, and this can make it slightly more complicated to narrow down which door will work best for your needs while staying inside your budget. 

Additionally, a more ornate door can easily boost your home’s decor without increasing your cost to install interior doors since most of them have the same installation process. Simple or ornate, thin or fire-resistant, you want to think carefully about the whole room’s look and feel when you start browsing the different interior doors that are available. This can give you a chance to find out which style you really like, and you can pick the door that falls inside your budget for both materials and maintenance. 

Generally speaking, the average cost to install interior doors range from $350 up to $1,100. Most people will spend around $725, and this is to pick out and install a solid wood prehung door with hinges. If you want to replace an existing closet or bedroom door, this will cost between $100 to $300 in labor. The door itself will increase your cost to install interior doors by $50.00 to $500. If you pick out more high-end French doors with ornate decorations on them, the price can easily jump to $4,500 or more. 

Since this is such a broad range and you shouldn’t have to sacrifice looks for quality, we’re going to outline everything you need to know about which factors go into your final cost to install interior doors. Doing so will help you get a good feel for this project’s scope, and you can use the prices to get a rough estimate of how much you should set aside to complete it.

Price Points for Different Interior Door Materials

One of the first things you’ll realize is that these types of doors come in a broad range of materials, and each material will influence your final cost to install interior doors at different rates. It’s also possible to break your doors down into exact categories using their weight, use, and cost. At this point, we’re going to use more broad categories based on materials, including: 


Sliding doors are popular leading out to patios or other outdoor areas. You can get sliding doors with solid glass or French-style doors with glass panels surrounded by wood. By themselves, they have a lower insulation level to them, but it’s possible to buy thicker models that come with much better sound-insulating properties. The frames come made out of a variety of materials, and they’ll increase your cost to install interior doors by $500 and up. 

Hollow Core

If you choose a hollow core door material, it uses a skin or shell made out of vinyl, wood, or MDF that has nothing inside it. These are very lightweight doors that are inexpensive. They have a quick and easy installation process, but they won’t absorb or block sound as well as other options. They’re budget friendly at around $20.00 and up. 


This type of door can be completely solid, have a hollow core, or it can have a solid core. It’s a very versatile choice because it comes in a huge range of styles to choose from that match a range of decors. This is a slightly more stable choice than solid wood options. Humidity won’t impact them much, and you get a very smooth surface that is easy to paint. This type of door will make your cost to install interior doors increase by $20.00 and up for materials. 


You can get metal doors that are steel over foam, and they can come painted to look like wood. You can also get unpainted steel for a more industrial look to them, or they come in aluminum. The traditional use for this door is as a security door for a garage or home office, but they’re very popular in modern or contemporary homes too. A metal door will increase your costs to install interior doors by $100 and up. 

Solid Core

If you pick out a solid core door, it usually comes with a thin veneer made of MDF, wood, or vinyl. This veneer goes over an inner core that features wood pulp. Although this door is a lot lighter than solid wood, it won’t be as light as a hollow door. Since it has a core to it, it’s better at insulating against sounds than other options. This door can increase your cost to install interior doors by $50.00 and up. 

Solid Wood

As the name suggests, this type of door comes made from a single, solid piece of wood. You can pick out highly decorative patterns or plain, and it uses several different wood species to allow it to come in different styles. This is a heavier door, but it also insulates against sound extremely well. The cost to install interior doors starts at $100 and goes up with more decorative options. 

2 Door Material
Lightweight doors are generally okay for interior use. However, if you want something more heavy-duty, they work for entries where you lead outside. The heavier the door is, the more your cost to install interior door will be.

How the Type of Door Impacts Prices

One big point for your final cost to install interior doors will depend on the type of door you pick out. Some styles will impact how easy or complicated the installation process is or how the door functions, and some are more of a personal style preference if you want them to match your design style


An accordion door is usually put in smaller spaces where you don’t have room to install a pocket door and it’s now wide enough for a barn or sliding door. This door will fold up like a pleated accordion when you open it. You can pull it closed across the opening and fasten it on the other side to close it. Usually, you’ll find these doors with a mixture of metal and fabric or plastic. However, they’re very easy to damage with heavy use, and they’re usually a last resort when no other door will fit. Your cost to install interior doors with them falls between $20.00 and $100. 


A barn door operates like a sliding door on a track, and it has a very distinct style to it. You’ll have a visible track that the door slides along to open or close, rather than swinging outward. You can choose from several materials, and they all have a rustic or country look to them. They work very well in several different spaces, but you do need to make sure you have enough room to slide them open without concealing or blocking any important areas. Depending on the material, they can increase your cost to install interior doors by $150 to $2,000. 


If you pick out a bifold door, it uses several panels that will fold back against one another when you open it. You’ll see these doors in closets a lot, but they also work to help cover wide thresholds. You can choose from several materials and sizes when you pick bifold doors, but they’ll have to have a track to slide open and close on when you get them. Depending on the size and materials, your cost to install interior doors with this style ranges from $100 to $2,000 for materials alone. 


A Dutch-style door is a single door that gets divided in half around the midline of the door. This division allows the top and bottom to open independently, and they’re popular in more rustic decor. They can be extremely heavy, and they usually feature a wooden design. They’re great for people with pets or to put in kitchens because you can shut the bottom half and secure it while leaving the top half open. On average, they’ll boost your cost to install interior doors by $500. 


These are some of the most budget-friendly models available for doors, but they’re also some of the plainest you can find. You can pick from several materials, but they come with a very simple and flat appearance. The door will lie flush to your door frame. They work well in contemporary designs or for closets, and they’ll increase your cost to install interior doors by $20.00 to $200, depending on the material you pick out. 


This is a set of double doors that feature panes of glass. You can get panels or multiple panes surrounded by a frame. They will open up together to give you a wider, single opening in your doorway, and you typically see them leading outside to your pergola or deck. They also work well in living rooms or dining rooms, and they add a little drama and style to your design. The cost to install interior doors for materials with this style ranges from $200 to $2,000. 


Almost all interior doors are a single hinge design. They can be prehung, and this means that they already have hinges and a frame when you buy them, or they can come blank and have no frame. If you already have an existing frame and hinges, you’ll typically buy a blank door. Otherwise, you’ll want to pay more for a prehung door. You can pick from a large material range with different sizes, and they’ll increase your cost to install interior doors by $20.00 to $2,000 per door.

This type of door has a unique and slightly more complex installation cost, and this can drive up your total cost to install interior doors. You’ll buy a single, large door and hang it on a single hinge in the center of the door. If you push the door from either side, it’ll open and pivot using the hinge. They work very well for busy spots in the house like your kitchen, but they’re not good for areas that need more privacy like the bathroom or bedroom due to how they open. You can expect to pay between $200 and $2,000 for this door, and the material is the driving price factor. 


This style door works to help save space. The door will slide right into the wall rather than opening in an outward motion. They use different materials and come in several styles. You’ll see them in bedrooms or bathrooms, or any room with small space requirements. However, they can have a large price tag when it comes to installing them, especially if it’s in an existing home.

This pick will increase your cost to install interior doors by $120 to $1,000 each. 


Roller doors are much less common in residential homes, but they do work in contemporary or industrial design aesthetics. The door opens by sliding along a roller across your ceiling. They won’t cover the walls, and they’re good at space-saving. However, they’re difficult to maintain and more expensive upfront, and they won’t work if you have high ceilings. The cost to install interior doors in this style starts at $500 for materials alone. 

Sliding Bypass

You can choose to have a sliding door and a fixed panel or two sliding panel doors with this style. They’ll slide on parallel tracks to bypass one another when you open or close them. They work well in wide thresholds where you don’t have room to install French or barn doors but you need to save space any way you can. These doors can jump the tracks relatively easy, and they can be heavier and harder to move. However, they’ll cost around $500 and up for a set.

Sizing Your Interior Doors

Any interior door has to have a minimum height up 80 inches. This is the standard measurement for most homes. They also have a standard width of 24-inches, 28-inches, 30-inches, 32-inches, and 36-inches. If you want to convert a home to age in place or if you want an accessible home, your door sizes have to be at least 36-inches across to qualify. 

It’s common for homes to have doorways that span from 30 to 36-inches in hallways or going in and out of rooms. Closets can have smaller doorways, and you can find smaller measurements in small rooms like half-baths or in older homes. 

Installing Your New Door

If you choose to get a prehung door, the installation process is fairly straightforward and quick. The contractor will trim your jamb and door frame to fit the opening. They’ll double-check the rough opening and install temporary cleats to hold the frame in the correct position as they nail it in. Then, they’ll lift the frame and door into place before shimming the door to open and hold it. If they need to make fit adjustments to the rough frame, now is the time. They’ll nail the frame into the opening’s studs before installing the door. They’ll install your trim if needed.

A blank door installation takes more time and it can be more labor-intensive. The contractor will have to measure and drill spaces for the hinges and other hardware into the frame. Then, they have to check that the alignment is correct before marking and leveling it. They’ll apply temporary cleats to hold the door in place when they attach it to the frame, and then they’ll install the hardware. 

It’s also important to note that blank doors can add to your cost to install interior doors because you’ll have to finish them before installing them while prehung doors usually come finished and ready to go. This can increase your labor costs. 

Labor Costs

Your cost to install interior doors is around $175. This is for installing the door and frame. If you want your contractor to install the trim and make sure that the hardware is in the correct place, this will usually add between $75.00 and $100 to your total. If you purchased a solid wood door for $475, the labor will add between $250 and $275. There would be more costs to consider when you add hardware in. 

Different types or doors can add or take away from your total cost to install interior door estimates. Heavier doors will usually cost more to install with hollow doors costing less. Some companies will offer bulk discounts to help save a little more money if you choose to have multiple doors installed at the same time. Sliding doors and pocket-style doors have more costs associated with it because you have to finish the drywall after you install them. 

Costs to Replace the Frame

If the door itself is in good shape but your frame isn’t, you could choose to keep the door and replace the frame. This can save you on your total cost to install interior doors. You’ll pay around $125 for this service. For most doors, the cost range starts at $100 and goes up to $225. It works out to an average of $7.00 and $15.00 a linear foot for labor and materials. It usually takes between one and three hours to finish, but the total time will depend on the type of frame, condition of the surrounding walls, and the size. 

Hardware and Trim Costs

It’s common to have to replace the trim when you replace a door, and this can add to your cost to install interior doors budget. Trim is the piece that fits over your door frame. They’re not necessary for your door to function well, but it can help to enhance your interior design or support it.

If you choose not to buy a prehung door, you’ll most likely have to budget for hardware like a strike plate or a doorknob. On average, buying trim and installing it will increase your cost to install interior doors by $155, and hardware can cost between $20.00 and $200. 

Picking Out the Best Doors by Room

It is possible to install the exact same door in every room in your house, this may not be the best option. Some doors are heavier than you necessarily need, and other doors aren’t good enough at absorbing sounds like hollow doors. You want to consider how you’ll use the space when you decide on which door goes where, and the following work well: 

  • Bathrooms – Pocket doors, solid-core doors, and solid wood doors
  • Bedrooms – Solid-core doors and solid wood doors
  • Closets – Bifold doors, hollow-core hinged doors, and sliding bypass doors
  • Dining Rooms – Barn doors, French doors, sliding bypass doors, and pocket doors
  • Kitchens – Dutch doors, pivot doors, and pocket doors

Optional Improvement Costs

There are a few things you can do to improve the look of your door, but they’re purely optional. So, if you’re at the high end of your cost to install interior door budget, you may choose to forego these measures. Two of the biggest costs include: 

  • Old Door Removal – If you want to replace an existing door, you might have to pay the company to remove the old one. This fee will depend on how challenging it is to remove the old door from your house. If you choose to get rid of the frame at the same time, this will increase your costs. Costs range from $20.00 to $50.00. 
  • Painting – If you install a slab door, you’ll need to paint or finish it when you install it. You could also choose to paint the other doors in the house at the same time to match. You’ll pay around $100 to paint the doors.

The narrowest width for a standard interior door is 24-inches. You may find that older houses can have more narrow doorways, but this is usually for a small closet. 

2. Why do doors sag?

Over time, the door’s weight may make it pull off the frame. This will cause the hinge screws to loosen up a little big, and the door will sag. Humidity can also make the door frame buckle and swell, and this can lead to sagging. 

3. How much does it cost to close up an old doorway hole in a wall?

If you decide to move your door, you’ll have to make a new area for it and close up the old one. Wall installation will add to your cost to install interior doors by $300 to $800.
