Door casing is the trim at the outer edge of the door’s opening which hide the gaps between the jambs of door and the wall finish. It can create a conventional look and feel for each room of the home. It is available in a vast range of styles and shapes. Mostly people use butted door casing which is quite simple and graceful door casing style. You must follow the given steps in order to install butted door casing.

Step 1 - Take Appropriate Precautions

Always wear eye protection when using hand or power tool, especially while cutting, nailing and demolition. Make sure that the area, where you will work is safe. To prevent injury, remove nails, which have been detached, from the moldings. Keep in mind if you are installing case on the doors, outside the building then you must use weather-resistant fasteners.

Step 2 - Accurate Measurement of Door

Make sure that the door-jamb is flush with the wall surface and adjust as necessary. Measure the exact size of your door with the measuring tape. Make sure there is no mistake in the measurements because it may cause problem in installing and cutting of door case. Remember that in the butted case style, a 1/4-inch line is left around the edge of the door-jamb and the casing is attached with this line therefore the measurements must be taken from here.

Step 3 - Choose the Casing Type

Choose the type of the casing wood according to your choice to enhance the beauty of your doors. They are available in 2 types, tapered casing and symmetrical casing. You can easily get them at any carpentry shop. Always use thin edge of the casing because it keeps the nails back almost 1 inch from the ends of moldings.

Step 4 - Cutting of Trim

Now cut a piece for casing, it must be a little longer than the sides of the door. You can get accurate measurements by placing the piece of trim against the edge of the door-jamb. Or you can use your measuring tape for cutting the trim. Use the miter-box saw to cut the trim according to your measurements. You may give your butted door case a little fancy look, by leaving an extra 1/4 inch while cutting the top piece of the door case.

Step 5 - Assemble the Pieces

After cutting the pieces according to the measurements of all sides of the door, now assemble the casing unit. Apply the wood clue on the edges of the trim pieces. Line them up and fix them together. Now let the clue dry for some time. From the top edge drill 2 holes on outer side. Screw in two long screws, which will lock the pieces together. Now repeat same procedure with the other corner of the case.

Step 6 - Attach the Door Case    

Now place the assembled door case around the doorjamb and nail the inside corners and the outer edges of the casing into the door’s frame. For this purpose you must use slightly long nails which can go through the case and drywall into the frame of the door. To finish the task, use caulk to fill the gaps and wood filler to fill the nail head holes. Now you can paint the case according to your need.
