Plinth blocks are a great way to decorate the outside of your home. In the first stage of the instructions on how to fit these items into your window or door frame, you measured, marked and cut the plinth and casing in preparation for the installation. You will now need to fit the plinth blocks around the surrounding casings in your window or door. In order to do this, you will need to further fix the casing to the rest of the window, install the plinth blocks in the window, and add trim so that the blocks are held firmly in place. This should not take too long, and can be easily accomplished by following these instructions.

Step 1  - Fix the Casing

In order to keep the casing in place, you will need to fix it firmly by using nails. Finishing nails are the best type to use on the outside of a window, although you can use whatever kind of nails you choose. Finishing nails are easily obtained from local hardware shops. Make sure that your casing is properly aligned with the rest of the window frame, or door frame, and then push the nails firmly through the entire casing.

Step 2 - Install the Plinth Blocks

Take your plinth block, and position it into the gap in the casing where you want the blocks to be. Position the blocks against the marks that you made using the combination square, and ensure that they fit tightly against the edges of the casing. If you are unsure about the placement, use the square to reassure yourself.  You can then nail them into the window by using the finishing nails. Keep tapping the nails until they are fully into the wood, as this will prevent them from being seen on the outside.

Step 3 - Fit the Trim

Take the pieces of trim that you cut from the plinth at the beginning, and place them around the plinth blocks. This should keep them in position. If you are fitting the casing at the top of a frame, make sure that the trim fits around the edges of the casing tightly, to prevent it from falling out at a later date. You should also nail or glue the trim in place to give it added strength, although you should make sure that you nail the trim to the frame, rather than the plinth blocks.

Step 4 - Install the Caulking

Once you have fitted all of the trim, and it is carefully aligned with the blocks, you should then cover them over with a layer of caulking. Make sure that the caulking you have chosen is water proof and compatible with wood staining. If you wish to paint the wood casing and plinths, you will also need to make sure that the caulking is suitable for that.
