Framing a door can be a great DIY project, that is if done right.
Here are the steps that you can follow:
How to frame a door
Buy your door first so you can measure it and base your frame from those measurements. You’ll also need 2×4 lumbers, a level, some nails, a circular saw, and a hammer or nail gun.
From your measurements, add two inches to the width and 1½ inch to the height to know the exact dimensions of your door frame.
- Use a saw to cut a top plate with the same width as the rough door opening. Nail this piece into the ceiling joists. Do the same with the soleplate and attach it into the floor joists without nailing the part between the width of the door since you’re going to remove some of it.
- Create your king studs by cutting four pieces of wood with the same height as the distance between the top and soleplate. Nail the two king studs against between the plates and against the sides of the opening. Install the other two with the same width as the door plus five inches.
- Create your jack studs by cutting two pieces of wood that are the same height as the new door plus 1 ½ inch. Nail these parts to the two inner king studs.
- Create a header by cutting two pieces of wood with the same width as your jack studs and nailing them together, after which you should nail that header to your jack studs.
- Create cripple studs by cutting one or two pieces of wood with the same width as the distance between the header and top plate. Nail those studs in place.
- Cut out the soleplate between the jack studs using a saw and you’re all set to install your new door.
How to frame a wall with a door
If you’re extending space or building a basement or shed, you would need to build a wall with a door in it.
In that case, you would also need to know how to frame your door together with your wall. But before you do that, check your local building code to make sure that you’re complying with all the standard rules of building a wall with a door.
- Start by measuring the length of the wall that you’d want to build and include the ceiling height in different areas of that wall. Find the shortest floor to ceiling measurement and use that as your reference in building your frame.
- To know how many studs you’ll need to build the wall, divide that length by 16 inches, and add two studs for your “end studs.” Use 8-foot lumber for lengths 8 feet and below and 10-foot lumber for over 8 feet.
- Take account of the materials for your door frame, which will consist of two king studs, two jack studs, and a header.
- Cut your top and bottom plates following the length of the wall and cut all your studs according to the shortest ceiling measurement subtracted by the thickness of two plates.
- Cut your jack and cripple studs according to the measurements of your door opening. Also, cut the header according to the same measurements of the frame.
- Build your wall frame by putting the top and bottom plates side by side and mark both plates simultaneously measuring every 16 inches along the length for your studs. Also, don’t forget to mark the location of your door opening.
- Separate both plates and put the studs between them according to your measurements. Attach all the framing members using a nailer to create your wall. Make sure that the jack studs have the correct distance for your door casing. Nail the king studs, jack studs, and header in position.
Finally, you can then position and attach the wall making sure that everything is fitted properly. Use a drill with a masonry bit to drill a hole for securing the wall with the door frame to the concrete floor.
After everything is in place, you can cut the bottom plate so you can already attach the new door.
