The Basics to Interior Door Casing

Interior door casing is not difficult and it seems everyone has their own particular way of doing it. My way of casing an interior door is quick and easy and for complete instructions for this project go to this page casing-interior-doors These instructions are explaining the most common and popular styles of casing which include some styles such as Ranch, Colonial or Princeton.

There are a few things to keep in mind while attempting a project of this type to get a good professional look. Whether you are picking out the trim wood at the store or sorting through a pile you have available match your wood. The same type of wood species can have a broad range of color and the wood grains can vary quite a bit so matching your wood will give you a uniform look with each door you trim. If you are trimming multiple doors and this happens to be your first time with a project like this then practice on a door that is not in a highly visible place. Also save the nicely matching pieces of casing for the highly visible areas.



If you are trimming one door for the first time and it is in a highly visible area then read the instructions on this page casing-interior-doors slowly and carefully. On this page at finish-carpentry-tips you will find some helpful tips that will dramatically increase your ability for getting the job done successfully.

The Best Tip for Interior Door Casing

If you have made it this far down on the page you are going to get the best tip for success. When you cut a 45 degree angle on your casing you will want the angle to have a slight back cut to it. What this means is when you have this slight back cut at the 45 degree angle cut on both pieces the outside face of the casing will meet together tightly and it will be easier to achieve a tight miter joint.

There are a couple of ways to do this one is to set the casing on a small piece of card board next to the saw blade on your miter saw and then just cut the 45 degree angle. To explain this better, at the place where the blade actually cuts the casing the casing will be slightly lifted off the saw because of the thickness of the piece of cardboard. This cardboard only needs to be an inch or so wide and be the length of the width of the casing.

Another way is to cut the casing upside down on the saw. This will provide a natural back cut at the angle because of the profile of the casing. This works well with the styles of interior door casing like ranch, colonial or Princeton because the casing is thinner towards the inside and the outside edge is thicker. Be extra careful doing it this way if this is your first time trimming as cutting the right 45 degree angle can be confusing. I know this from the experiences of training in people to be finish carpenters.
