Installing a door with frame: Proper Frame Installation

Installing an interior door | RONA

Do it yourself

Interior doors are such a part of our daily lives that we hardly pay attention to them. Yet a well-chosen and properly installed interior door can enhance the decor and is likely to be noticed. Selecting the right model is therefore important.

The following project shows how to build the door frame, cut the notches for the hinges, and drill the holes for the handle and lockset. If you already have a pre-hung door, see step 2 for how to install it in the opening and step 5 for how to fit the handle.

Difficulty level: Intermediate

Duration: 3 hours

A note about interior doors

Pre-hung interior door: door already mounted in a frame and fitted with hinges and a hole for the handle. Quick and easy to install in the opening.

Pre-machined door frame: Quick way to hang a new door. The frame is already cut and ready to be installed in the opening. The hinges and door stop moulding are usually already mounted. Offers greater flexibility when selecting a door. 

Build a door jamb: While it is relatively simple to build a door jamb, and this allows you to custom-fit it to the opening, its construction does require a little more precision.  

Door: Interior door slabs (the door without the frame) come in different widths between 24″ and 36″. Typically, 30″ doors are used for every room in the house except the door leading to the basement, which should be 32″ wide (or greater), space permitting.

A 30″ door mean the width of the door slab itself. The frame adds an additional 2″ in width and 1″ height. Standard doors are 80″ high. You must allow a clearance of ½” between the bottom of the door and the floor.

Hinges: Both the number of hinges used and their size depends on the type of door and how thick it is.

  • Hollow core interior doors: two hinges
  • Solid-core doors: at least three hinges

The top hinge should be placed 7″ from the top of the door, while the bottom hinge should be 11″ up from the bottom.  

Floor allowances: Both jamb sides can be adjusted from 3/8″ to 1″ above the floor depending on the floor covering that will be installed.

Average Door Frame Replacement Cost

Before we dive into the details, let’s take a look at the average cost of replacing door frames. Keep in mind that these prices assume that the door itself is still in good condition and does not require replacement.

Average Cost $350
Highest Cost $150
Lowest Cost $700

Door Frame Replacement Cost Breakdown

How much does it cost to replace a door frame? Replacing a door frame can involve a range of costs depending on various factors. Typically, the type of door, materials and labor are the primary expenses. We will discuss them below.

By Door Frame Type

Most door frames typically consist of two jambs that run vertically parallel to one other, a crosspiece on top and a sill on the bottom. Although the size and shape of the door frames might vary depending on the opening and the door, rectangular door frames give the most strength and longevity. Here is a breakdown of the average cost of replacing different types of door frames.

Interior $150 – $250
Exterior $200 – $400
Sliding $150 – $300

Interior Door Frame

Interior door installation generally costs less than exterior door installation. This is because inside doors are less robust and they have a different purpose. Expect an average of between $150 and $250 for the cost to replace an interior door frame. Specialty doors, such as French or barn doors, need different types of frames, which are often more expensive. The cost of replacing high-end door frames can go up to $1,100.

Exterior Door Frame

Exterior doors are often heavier and more sturdily constructed than inside doors. They’re often made of wood, fiberglass or steel, with matching frames. Front doors are vital for security, safety and entrance, hence they usually include deadbolts. Because exterior doors are built differently, they also require different door frames.

The average price to replace a front door frame is around $200 to $400. The exterior door frame replacement cost can be higher for certain projects, such as replacing the garage door.

Sliding Door Frame

Sliding doors can be used both outdoors and indoors. Indoors, they are typically used as closet doors with frames that include a track and vinyl rollers. Outdoors they are used for instance as patio doors and they are made with a different system and with different materials.

The cost to replace a sliding door frame ranges from $150 to $300 on average. The exact cost depends on whether you want to replace an inside or outside door frame, the size of the frame, the type of material used and the cost of labor in your area.

Additional Costs and Considerations Associated With Door Frame Replacement

If you want to know how much it is to replace a door frame, you need to look at other costs and considerations too. Aside from the cost of the door frame itself, labor and materials play a part in the final cost of replacing a door frame.

Labor (Repair vs. Replacement)

The cost of labor for replacing a door frame can vary depending on whether the job involves repair or replacement. Repairing a door frame is typically cheaper than replacing it. However, repairing may not be the best option if the damage is severe, if there are signs of wood rot or if the frame is outdated.

The price of labor depends on the type of contractor you hire. A handyman or day worker will usually charge between $40 and $50 per hour, while a professional licensed contractor skilled in door frame replacement will charge between $60 and $100 per hour.


Most homeowners choose wooden doors and door frames because they are easy to install and less expensive. Composite is also used for door frames because it doesn’t splinter like wood, but has a similar look and feel. Other options include vinyl, aluminum and fiberglass.

Materials that are needed for door frame replacement include fasteners, flashing, caulking and shims. For one door, you can expect these to cost around $10 or $20.

DIY Door Frame Replacement vs. Hiring a Professional

Replacing a door frame can be a challenging task, especially if you have no experience in carpentry or construction. It’s essential to do it correctly to ensure the safety and security of your home.

While some homeowners may do the work themselves, it’s recommended to hire a professional contractor to ensure that the job is done correctly. A professional door frame replacement will cost more upfront, but it can save you door frame repair costs in the long run by avoiding pricey mistakes or safety issues.

How to Save Money on Door Frame Replacement

Replacing a door frame can be expensive. But luckily there are ways to save money on the cost of door frame replacement.

Get Multiple Quotes

Make sure you don’t overpay by getting multiple quotes from different contractors. Always check their references, insurance and licensing before hiring them. Compare costs and ensure that you’re getting a fair price.

Consider Repair Instead of Replacement

If the damage is small, ask the contractor to repair the door frame instead of replacing it. If the frame is too damaged or shows signs of wood root, this is not an option and you will need a new door frame to replace it with.

Door and Frame Replacement

Do your doors look a bit worn? Will it soon be time to replace them too? Replacing the door and frame at the same time will save you money since you will only have to hire a contractor once. Bigger projects usually mean you will receive a discounted price.

DIY as Much as Possible

If you’re handy with tools, consider doing some of the work yourself to save on labor costs. Removing the old door frame, prepping the opening and painting or staining the new door frame are tasks that can be done by a DIY enthusiast with some basic tools and knowledge.

Ask for Discounts

Don’t be afraid to negotiate with contractors to get the best deal on the cost to replace a door frame. If you have multiple quotes from different contractors, use them as leverage to negotiate a better deal. Be clear about your budget and ask the contractor to work within it. Some contractors may be willing to offer a discount if you agree to pay in cash or upfront, so be sure to ask about payment options.

Frequently Asked Questions (FAQs)

Can you replace just a door frame?

Yes, you can replace just the door frame without replacing the entire door. Make sure the new door frame matches the style and size of the existing door. However, keep in mind that replacing just the frame may not be a viable option in all cases. If the door itself is damaged, it may be more cost-effective to replace both the door and the frame.

What is the difference between the door jamb and the door frame?

The door frame is the entire structure surrounding the door, including the sill, jamb and head. The door jamb is specifically the vertical part of the door frame that the door hinges attach to and the locking mechanism engages with.

How do you fix rotted wood around a door frame?

To fix rotted wood around a door frame, you first need to remove the rotted wood and replace it with new wood. This process typically involves cutting away the damaged wood, treating the surrounding area with a wood preservative and attaching a new piece of wood to the area using wood screws or nails.

What causes the bottom of a door frame to rot?

The most common cause of rot at the bottom of a door frame is water damage. This can be caused by a variety of factors, such as rainwater pooling around the base of the door, poor drainage or a leaking roof. It’s important to address any sources of moisture as soon as possible to prevent further damage.

Door installation tools

As a rule, doors are installed at the stage when the interior finishing has already been done: the floor has been poured, wallpaper has been glued and the ceiling has been painted. This helps to avoid premature wear and damage to interior doors.

Tools should enable you to carry out all operations related to the installation of the door. Therefore, we will consider the tools used in the context of the main operations.

Door installation steps

When buying or manufacturing doors, it is taken into account that the size of the door together with the door frame is 3-6 centimeters smaller than the opening itself. This stock will help you accurately line up the doors.

1. Dismantling the door and the old frame kits with them


or screwdrivers :

They are also used when assembling the box and fixing it in the opening.

2. Matching the frame and extensions

The main problem in assembling the door frame is to make the butt joints correctly. Crossbars and jambs, as a rule, have a profiled structure, so the most difficult thing is to make cuts clearly at 45 degrees.
In practice, novice door installers actively use manual miter boxes :

Do-it-yourself interior door installation

Interior door creates a feeling of comfort and security in the room, decorates the interior, eliminates unwanted sounds. In order for it to become its full-fledged part and serve for at least 5-10 years, it is necessary to properly install the interior door. How to do it? We will tell you step by step in the instructions. Of course, in our case, the ideal option is to turn to professionals, relying on their knowledge and experience. Moreover, if you order a door from a manufacturer, the installation of interior doors can be provided as an additional service. If, for one reason or another, you decide to put this burden of responsibility on yourself, read our article-instruction. She will help you to install a new interior door correctly and with your own hands without common mistakes.

First step: assessment of the premises

First, assess the condition of the room. For example, if you are renovating a room or apartment, keep in mind that you can start installing the door only when everything is plastered and puttied, but at the same time, before the stage of covering the walls with paint, wallpaper, etc.


Decide in advance on the floor finish and installation location in order to select the dimensions of the door frame as accurately as possible

before installing the door, all repairs in the bathroom, bathroom and kitchen must be completed. Otherwise, there is a risk that the door will change its shape due to dampness and become unsuitable for installation. The exception is doors made of LVL-beam, which protects the entire structure from moisture and temperature changes.

check the surface of the door. It should be perfectly smooth, without roughness and protrusions. The slightest unevenness can interfere with the opening / closing of the door

before installation – carefully check the package: whether the dimensions of the canvas correspond to the dimensions of the box and the doorway

it is unacceptable to install doors near heating or heating appliances

Specialist comment:

“Before installation, in the case when the interior doors were in a temperature and humidity regime different from the operational one, especially in winter, it is recommended to keep the interior doors in the room for five days to acclimatize them.

Head of Technical Control Department of RADA DOORS, Mubarakshin Marat Galimzyanovich


Prepare all the necessary tools in advance. Depending on the installation method, you will need:

Basic tools: miter box, saw or hacksaw, chisel, drill with nozzles (crown), screwdriver or screwdriver, hammer, wedges.

Items: self-tapping screws for box assembly 4×50, universal screws 5×80, dowels, finishing nails.

Auxiliary tools: knife, pencil, tape measure, square, building level, polyurethane foam.

Third step: preparation of the door frame

The door frame is a construction of one horizontal and two vertical profiles forming the letter “P”.

Self-installation assumes that you have to adjust the door frame to the product with an accuracy of up to a millimeter. An alternative option is to order the necessary “components” from the manufacturer. As a rule, their dimensions ideally match the dimensions of the purchased door, while some manufacturers have door frames that are completely included.

After you have taken measurements, prepare the frame, taking into account possible errors. Don’t be afraid to practice on spare racks:

  1. Sawing two uprights at a 45° angle.
  2. On the inside of the rack, measure the distance, which is calculated by the formula: door length (exactly, to the millimeter, with all errors; for example, 2003 mm) + 4 mm (top margin) + 10 mm (bottom margin).
  3. Saw exactly along the marked line on both posts.
  4. Take the upper component of the door frame (lintel), then measure a distance along the inside of the part equal to: leaf width (for example, 900 mm) + 4 mm (margin from the lock side) + 4 mm (margin from the hinge side). Saw off the headboard on both sides at a 45° angle.
  5. The door frame is almost ready. Perpendicular to each other, tighten the finished racks and the lintel with self-tapping screws. Use three 60mm self-tapping screws for each cut.

Fourth step: fitting hinges

The door frame is ready. Let’s move on to the next step – installing the hinges. Contrary to popular belief, we recommend installing interior doors with both two and three hinges on your own.

Keep in mind that there are three types of loops: left, right and universal. If you plan to open the door towards yourself with your left hand, choose the left ones, with your right hand, respectively, the right ones. A win-win option – universal.

So, step by step instructions:

  1. Make three marks on the door leaf with a pencil: the first one is at a distance of 250 mm from the top edge, the second one is at a distance of 500 mm, the third one is similar to the first, but already from the bottom of the product.
  2. Alternately attach the loops so that the marks are perpendicular to the center of the loop. Mark the edges of each of the loops with additional serifs (using a pencil).
  3. After that, fix each hinge in turn with self-tapping screws so that it is in a stationary state. Next, with a milling cutter (or in extreme cases with a chisel), make 2 mm cuts around the entire perimeter of the loop. The indentation has been made.
  4. Next, put the loop in the groove, then mark the holes for the screws with an awl (or drill). Screw in the screws.

Now you can attach the canvas to the rack and try to reproduce the opening / closing of the door. This is necessary in order to understand how much it is necessary to deepen the loop in the rack. Landmark – when closed, the gap between the door and the rack should be 4 mm.

To prevent the door from creaking in the future, make sure that the axial connection of the hinges does not come into contact with the door leaf and the racks of the door frame.

Important: the measurements on the racks are done in the same way!

Fifth step: installing handle

Self-installation of the handle on the interior door takes place in two stages: first, you insert the handle with a latch, and only then, when the door is hung on the hinges, proceed to the second stage – attaching the metal frame to the rack.

Let’s start with the first stage. First, decide on the height of the handle, more precisely, on the place of its installation. As a rule, it is located at a height of 90 to 130 cm from floor level. This is quite enough for both a child and an adult to open the door.

To mark the door, use the standard scheme that usually comes with the handle, or mark the door yourself with a square and an awl. To do this, position the center of the handle at a distance of 6 cm from the edge of the door on both sides of the door. Along the edge of the door – in its middle – also make a mark. This is the future place for the tongue from the castle.

Next, drill a hole in the door at a 90° angle. We recommend using a drill with a crown for this. The depth of the hole should be ½ of the total thickness of the door. The hole for the latch is made using a feather drill – it is proportional to the length of the internal mechanism of the handle.

Holes are ready. Now, using a router (or chisel), make a groove for the “dog” platform. The main thing is that in the future it does not prevent you from opening / closing the door. Attach the handle to the door, make sure everything sits evenly, and then mark the points where the screws will be screwed into to secure the handle.

Important: make sure that the holes are even and have the correct shape.

After you have placed the latch in the hole, fix it with self-tapping screws from the end part. It remains to connect the decorative elements of the handle on both sides.

Specialist comment:

“The standard size of interior door panels with a width of 400 mm and 550 mm is not standard and has a rack with a width of 85 mm. For this size, it is necessary to choose a narrow series of locks and latches.

Head of Technical Control Department of RADA DOORS, Mubarakshin Marat Galimzyanovich

Sixth step: installing the door frame and hanging the door

In the installation of interior doors, there are several ways to install the door frame. We will consider the most common and time-tested – installation with a solid solid frame.

  1. Fix the upper part of the door frame with wedges in such a way that the former are at the level of the junction of the transverse and upright parts.
  2. To secure the bottom of the box with wedges, align the hinged side, check with a spirit level in two planes.
  3. Measure the distances at the top and bottom of the box, allowing for 4 mm gaps. So, with a web width of 800 mm, the distance should be 804 mm.
  4. Secure the opposite side of the box with a wedge. Position the spacer against the lower wedges. For reliability, you can put additional spacers just below the handle and at the level of the upper loop.
  5. Now fasten the door frame to the opening with self-tapping screws that are screwed in on the hinges and handles. Hang the door using self-tapping screws according to the measurements you made in step 4.

Seventh step: foaming

It is necessary so that there are no gaps between the opening and the door frame. Before foaming, be sure to cover the door with some material so as not to spoil the surface of the product.

Next, place cardboard between the door and the counter, which will prevent unwanted closing of the door. The wedges installed between the posts must be left.

Tip: clean the opening of dust with a water spray. It is necessary for a better connection of concrete with foam.

When all of the above is done – proceed to foaming. Carefully and slowly, foam the door frame from top to bottom.

Leave the door to dry for at least 12 hours. After complete drying, cut off the excess foam, remove the spacers or pull out the wedges.

Eighth step: installing the metal frame for the handle

We have already installed the handle on the door, it’s time to move on to fixing the metal frame to the door frame. There are two ways to mark the location of the hole for the “tongue” of the handle:

smear the tongue of the handle with toothpaste and close the door. Opening it, the label we need will remain on the door frame

close the door, insert a ruler into the hole between the door and the opening and mark the desired point

Next, make markings for the metal frame on the rack, and then drill a hole with a pen drill. If the door opens / closes freely, you can proceed to creating a sample for a metal frame. It is made with a milling cutter (or chisel).

Important: the metal frame must be placed strictly flush with the surface of the rack.

Now drill the mounting holes and screw in the screws. Check if the door is easy to operate, if the latch comes out and in easily, if the door handle rotates well. If everything is fine, we proceed to the final stage of installing interior doors.

Ninth stage: installation of architraves

Let’s add beauty and elegance to the doorway – decorate the door with the help of an elegant frame – trim. As a rule, they come with a door leaf.

The dimensions of the platbands are known to us from the previous paragraphs – we proceed to their fastening. To do this, you need to make two cuts at an angle of 45 °, fix with finishing nails or glue. Ready.

True, there are a few “buts”:

if you bought high-quality doors and planned repairs, then be prepared for the fact that you will have to remove the trim to hang wallpaper. Agree, a rather dubious pleasure. An alternative is to find a door manufacturer with its own molding production in order to order new ones at any time.

noteworthy and the depth of the doorway, which can be non-standard sizes. In this case, before finishing the platbands, it is necessary to install an extension. Again, it is better to find a manufacturer who offers extensions of various sizes that are suitable for her in a set for an interior door. For example, at RADA DOORS, we solve difficult tasks of finishing non-standard sizes with the help of a system of universal extensions.

As you can see, installing an interior door at home with your own hands is not an easy task. One mistake is enough to ruin an expensive door.
