The trim around a door frame is also known as casing. Its primary function is to increase a home’s energy efficiency and enhance curb appeal. Once an exterior door is in place, casing is typically installed on the frame, ideally before the baseboard and chair rail. The specific procedure for installing door casing can vary according to the type being used.

A major step in preparing a frame for new casing is the removal of the existing trim. This procedure generally consists of carefully prying the casing from the door jamb and wall with a pry bar. Score any caulk or paint lines on the exposed surfaces with a utility knife to avoid damage during removal. It may also be necessary to remove some of the baseboard if the new casing is wider than the old one.
The price of the trim itself is one factor that can affect the project cost. Colonial-style primed wood is one of the more expensive options, while narrower trim with a lower profile will generally cost less. Composite and vinyl trim are the least expensive options. The total length of trim needed also affects the cost since door casing is sold by the linear foot. If the trim requires finishing or if the frame or surrounding wall needs repair, expect additional fees.
The process of measuring and cutting the trim is the most technically challenging part of installing a new door casing. For example, matching the head door jamb to the trim on each side of the door is often a difficult task that benefits from prior experience. A professional carpenter will also be better able to operate a power miter saw, which is the preferred method for cutting door casing.
