Cutting Door Casings Cutting Door Casings
Whether you have installed a new door and want to put in matching casing around it, or replacing existing door casings due to damage, there is no need to pay out your hard earned money to a professional. With this how-to guide you can construct door casings for the price of the raw materials.
Step 1 – Preparation
Take measurements of the doorway, checking that both the left and right sides of the doorway are the same length and what the length along the top of the door is. It is important to check that the corners of the doorway are square; if they are not a perfect square then you will have to adjust your mitre cut accordingly.
Step 2 – More measurements
When putting in a door casing, it does not just fit it in the doorway; it overlaps with an area of the wall and this is called a door jamb. Usually, the door jamb is ¼ inches in height, but you are free to alter this to your taste. Using the example of adding ¼ inch, the height of your door casing will be your initial measurement plus ¼ inch. The width of the door casing will be your initial measurement plus ½ an inch.
Step 3 – Mitre Cuts
Remember that a door casing is made out of three pieces, the two vertical pieces and a horizontal piece. Make the mitre cuts, which are the diagonal cuts for the corners of the door casing, for the horizontal piece first followed by the two vertical pieces, once done place them together to make sure they join seamlessly. If the joint is not seamless then make adjustments. Use a file or sandpaper to make fine adjustments.
Step 4 – Gluing
Now it is time to put the door casing together. Glue the corners and clamp them together, this will ensure that the pieces of wood are firmly glued into the correct position.
Step 5 – Screwing
To ensure that the door casings are secure and stands the test of time, drill two pilot holes from the top of the horizontal piece down into one of the vertical pieces. In these holes, you need to screw in two long screws. Repeat this step on the other corner, so the whole structure has four screws keeping it together, none of which can be seen by people using the door.
Step 6 – Putting up the Door Casing
In order to put up the door casings, you will need a hammer and some nails. Start by nailing the corners into the jamb, once both corners are done you will need to place a few more nails attaching the casing to the wall. If you keep the nails evenly spaced apart then it will make more of a professional finish.
Step 7 – Finishing Touches
Simply use wood filler down the area where the casing meets the wall, smoothing out the substance with your finger. Unless you like the natural look of the wood, it is now time to paint and varnish the door casings.
