If you are looking for a quick way to make a door or window frame look more impressive, then fitting plinth blocks is one easy answer. Plinth blocks are available in a variety of colors, shapes and sizes, so there will be one to suit your home and surroundings. Fitting the blocks can be slightly more difficult, but once you have got the hang of fitting one, the rest should be easy. Whether you intend to use your plinth block to fit into the casing at the bottom of a window or want to place it over the top of the door, you will need some basic idea of what you are going. In this first installment, you will need to measure, mark and cut the plinth blocks to fit the window.

Step 1 - Choosing Your Plinth Blocks

When you are ready to purchase your plinth blocks, look for some that are the right length for your home. Choose one that has a similar color and appearance to items already fitted on the outside of your home, and also look for ones without cracks, holes or other flaws that might make it vulnerable to damage. You will be cutting the block, so choose one of a suitable size.

Step 2 - Measuring the Window

You will need to measure the window and the plinth blocks in order to work out the right size. This will be important when cutting. Measure the distance between the gap in the window or door frame where you want the plinth to go. You will need to add around 2 inches to the edge of each plinth in order to keep it in place in the frame.

Step 3 - Marking the Plinth Blocks

The next stage is to mark the plinth blocks. Take your combination square, and set the angle to about 3/16th of an inch. You should then mark both vertical and horizontal marks on the plinth. Mark the center of the block, so that you can easily find the middle, and then measure the length of your block. Using the measurements from the window, mark where you wish the cuts to be made.

Step 4 - Cutting Out the Plinth Blocks

Once you have marked the plinth block, you will need to make the cuts to ensure that it will fit into the casing. Take your saw, and remove all of the surplus amounts. Make sure that you repeatedly refer the block to the casing window before you start the cutting. As they say: measure twice, cut once.

Step 5 - Cutting the Casings

You will then need to trim around the edges of your casing to fit in the plinth. You can make a miter corner at either side of your casing material. You will then need to glue the casing pieces firmly in place using some standard wood glue and holding it in position with painter's tape while the glue dries.
