Introduction to Building an Interior Door Frame: Types, Costs and Benefits

Interior door frames are the foundation for your home’s interior doors and provide stability, durability and aesthetic appeal to both entryways and interior rooms. Building and installing an interior door frame can seem a daunting task, however with the right materials, tools and know-how you can easily tackle this job yourself!

Types of Door Frames

There are two main types of interior door frames: pre-hung door frames and cut-in-place/prefabricated frames. Pre-hung frames come already assembled with the jambs ready to install into an existing wall opening. Cut in place/prefabricated frames feature two jambs that fit together to form an outer frame – they need to be constructed on site with the use of wood screws. Prehung units eliminate any gaps between the jamb sides that could disrupt its function or decrease energy efficiency, so it is important to note if prefabrication is required before deciding which type is best for your project.


The cost of building an interior door frame will vary based on several factors such as size of frame, type of wood used (if using a prefabricated unit), etc. Generally, pre hung door frames range from – 0 whereas prefabricated models usually cost between – per linear foot. Of course these prices do not include installation costs which vary depending on complexity but could range from about 0-0+. In order to get an accurate estimate it is important to contact local contractor for project specifics!


Building an interior door frame can significantly enhance a homes aesthetics as well as being functional by creating a barrier against sound or weather elements if located near exterior walls or windows. The installation of pre hung units also adds extra insulation value while providing enhanced stability compared to conventional models due to their integral design. Not only is this type more energy efficient but since it doesn’t require additional framework around the opening there is no chance for air leakage either! Finally, building an interior doorway frame provides improved security against possible intruders who try access through vulnerable points like open windows or other unsecured structures in a home’s exterior walls

Tools Needed for Building an Interior Door Frame

Building a new interior door can be both difficult and easy. It is important to have all the right tools on hand in order to get the job done right. Depending on the type of frame being constructed, there might be differences in what tools are required however, most basic frames will require a few essential items. This blog post outlines some of the key tools needed for building an interior door frame.

The first tool you’ll need is an electric saw. This is essential for cutting boards, trim and other necessary components for framing. Make sure that the saw is sharp and properly lubricated before using it so that your project won’t suffer from poor cuts and too much friction wear and tear on its blade over time.

The second tool required for constructing an interior door frame is a nail gun. A nail gun is specifically designed to help create strong joints by correctly driving nails through pre-cut mortises without causing splitting or other damage to wood structures along their path. And while power tools may seem intimidating at first, they will save you both time and effort in the long run once you become accustomed to their use!

Thirdly, a miter saw will help make precise measurements when joining different lumber pieces together resulting in a sturdier frame overall compared with hammering joints into place while hoping they fit well enough when complete. The miter saw can also produce accurate angled cuts if you want decorative accents as part of your design like beveled edges or complex block patterns around openings such as transom windows within doors themselves.

Finally, depending on your type of door construction, clamps may be necessary for aligning pieces prior to nailing them together securely during the assembly process. Clamps come in multiple sizes so make sure you buy ones suited towards framing work when likely needing tension over extended periods versus smaller applications like cabinet construction where only temporary pressure needs application during installation tasks completed very quickly by comparison!

Step-by-Step Instructions on How to Build a Door Frame from Start to Finish

Building a door frame from start to finish isn’t as difficult as it may seem, and can be a great way to upgrade the home or office. After all, a good-looking, sturdy door frame adds both protection and aesthetic pleasure to any room, making it more inviting for guests. The following step-by-step instructions explain the process of building a door frame from start to finish, ensuring that you end up with the perfect combination of form and function.

1. Gather Materials: The first step in building a new door frame is making sure you have all of your materials ready and on hand. You’ll need lumber to build the jamb — two pieces for side jambs (vertical sides) and one piece for the head jamb (top piece). You’ll also need screws, nails, wood shims (for leveling), chisels (for cutting), galvanized mounting brackets (to secure the jamb against walls), saws and drill bits. Additionally, you should make sure you have sandpaper or putty knives on hand to fill in any gaps between pieces when needed.

2. Cut & Assemble Lumber: Now that you’ve gathered your materials together, it’s time to get started! Cut each piece of lumber according to measurements taken from the opening where the new door frame will be installed — ensure each cut is precise for an even fit later on. Once cut down into appropriate sizes, begin assembling them together into one unified structure— , use screws wherever possible to ensure maximum security between connecting parts of your wooden frame.

3 . Install Frame & Mount It Securely: One of the most important aspects of this project is properly installing the jamb so that there are no misalignments or gaps that can let air through; weak spots along the seams could cause damages due its lack of structural integrity over time due buildup moisture or other degenerating factors. Position it precisely in place before attaching galvanized mounting brackets on either side behind walls — this will also add extra strength to your newly formed door frame while keeping it tightly secured against these solid surfaces preventing warps in shape overtime caused by leaning against an unstable foundation..

4 . Review Your Work & Finish with Sanding / Putty Knife: After pushing away furniture out of way and stepping back review work done– inspect overall design seeing if there’s any misalignments anywhere which require minor adjustments; small triangular shaped woods shims are helpful here providing leveled support without distorting their appearance too much if placed correctly– sweep away debris left behind during installation process such cutting off uneven ends left by saw blades as well traceable locations where rusty nails/screws exist needing reattached securely& insulated against future rust . Next proceed with sanding edges eliminating any visible rough patches followed by cleaning leftover dust particles using damp cloth then apply putty knife along corners where deemed necessary filling minor cracks openings leading bigger issues down line….

Tips & Tricks for Installing an Interior Door Frame

Installing an interior door frame doesn’t need to be a difficult task, but it can be if not done correctly. If you’re renovating or just replacing the interior doors in your home, there are a few things you should keep in mind when installing the new door frame. First off, make sure the door frame is level and plumb by using a level and measuring any out of square parts. Then use shims to add a tight fit between the wall and the frame on all four sides. Make sure you have enough room around the hinges to allow for opening and closing easily without rubbing against the frame or wall. A common mistake is forgetting to cut out small sections around the hinges so that they are able to rest flat against each other and remain flush with no added adjustment needed for those areas. Next, screw in some long screws into studs through predrilled holes before adding shorter screws between each stud over top of the plywood strips to ensure extra stability when opening and closing if using this method. Finally, making sure all edges are cleanly finished with caulk will help prevent air leakage ensuring that potential cold air coming from outside won’t enter your home or precious hot air escape during winter months! Installing an interior door frame may seem daunting at first but getting familiar with these tricks could save you time in the long run!

FAQs about Building an Interior Door Frame

Q: What parts are needed to build an interior door frame?

A: To construct an interior door frame, you will need 2×4 boards, lumber screws, shims, and a hammer. You will also need a tape measure, saw blade or circular saw, screwdriver or drill/driver with appropriate bit for your type of screw head. Additionally, caulk and caulking gun may be used for weather-proofing the frame.

Q: Can I build an interior door frame myself?

A: Yes! Building an interior door frame is a relatively straightforward process with some basic carpentry know-how. If you have at least basic DIY skills and the necessary materials at hand then this project can be accomplished in a few easy steps.

Q: What is the best way to measure my interior door opening?

A: When measuring your door opening it is important to accurately measure height, width and reveal (space between wall surface and door jamb). Start by measuring the width of your current doorway at its base where it meets the floorboard then move up to record the height measurement twice – firstly the height from floorboard until just below where trim molding would stop and secondly including trim molding height. Finally take two additional measurements just inside both sides of trim molding – this will give you 3 internal measurements of reveal space which may vary slightly due to any irregularities in walls or floors which must be accounted for when constructing new frames. It is important to note these sizes carefully as precision in measurement equals precision in construction.

Q: How do I install an interior door frame?

A: Installing an interior door frame requires some physicality such as cutting boards to size according to previous measurements taken as well as driving nails or screws into studs during assembling so ensure that all required safety precautions are taken such as wearing safety glasses during cutting procedures and gloves when handling rough surfaces etc prior to beginning installation process. Firstly secure bottom board using lumber screws followed by sturdier sides taken from larger pieces cut accordingly – secure these firmly into place using shims if necessary until they fit snugly before moving onto top board or header; make sure top board seals tightly against side boards by checking diagonally across corners with leveler tool before securing each end with adequately sized screws into respective studs either side; finally fill nail holes with wood putty filler and caulk around entire perimeter of finished frame for extra protection against moisture penetration.

Top 5 Facts about Building an Interior Door Frame

1. Design: An interior door frame is essential in defining the aesthetic of a home as it provides a transition from room to room, giving the house a finished look. The design and hardware used for the frame can be chosen depending on the style of your interior, from traditional to modern.

2. Lumber: When constructing an internal door frame, the two main types of lumber used are Soft-wood and Hard-wood. Soft-wood is lightweight and often cheaper but has a lower tolerance for warping or twisting than hardwoods, which are heavier and more expensive but offer better stability over time.

3. Hardware: There are several pieces of hardware required when building an indoor door frame, such as hinges, strike plates, screws and jamb supports. Hinges connect one side of the door frame to another while providing support to open and shut it; Strike plates ensure latch bolts have something strong to attach to; screws provide extra strength at key framing joints; and jamb supports brace weak areas in order to prevent breakage under heavy loads like large furniture or slamming doors

4. Preparation: Once all supplies have been gathered, preparation should take place prior to installation in order to ensure a successful build—this includes measuring twice before cutting once! Measure both diagonally across each edge as well as vertically up each side in multiple places since even minor inconsistencies can lead to an ill-fitting door frame with visible gaps after installation

5. Installation: During installation, shim material should be placed between the jambs where adjusting screws can tighten them into position for a good fit against drywall or studs that form part of the wall opening followed by securing every joint with either glue or nails before finally attaching any necessary hardware mentioned earlier
