Stock Trim

However, stock trim may not be the best choice for exterior doors or for projects where a more customized look is desired. In these cases, it may be necessary to use a more advanced type of trim, such as custom-milled trim or pre-finished trim.

Custom-Milled Trim

Custom-milled trim is a more advanced type of trim that is cut to specific sizes and profiles. This type of trim is often used on exterior doors or in high-end residential construction projects where a more customized look is desired.

First, consider the style of your home. If you have a traditional or colonial-style home, you may want to use a more traditional type of trim, such as a 1x6 or 1x8 trim. If you have a modern or contemporary-style home, you may want to use a more modern type of trim, such as a 1x4 or 1x6 trim.
