Stop Moulding

Stop molding is perhaps one of the most under-appreciated pieces of trim in a house, but it can have a major impact on how a door fits, functions, and looks. It is installed along the inside edge of a door frame and provides the boundary against which the door closes, allowing it to fit tightly and reduce drafts, rattling, and gaps.

What is Stop Moulding?

It's a thin piece of trim attached to the jamb on either side of a door frame. It serves the purpose of "stopping" the door in its closing, enabling it to sit flush inside the frame. Without it, doors would swing past the jamb and not close properly.

This simple profile is available in many types of materials, such as wood, MDF, and vinyl. It can be left square-edged for a clean, modern look or feature a rounded contour for more traditional designs. This moulding has a dual role-it enhances both performance and appearance. By sealing gaps and providing a consistent stopping point, it improves privacy, reduces air leakage, and adds polish to the entire door system.

Whether it's an older door update or new installations, this trim adds craftsmanship and precision to the finishing process.
