How to Replace the Brick Moulding Around a Window

Brick moulding is the heavy square moulding that you often see around doors and windows of frame homes or brick houses. Though it's called brick moulding, it's actually made of wood. It's a bold style of trim, meant to accentuate the windows and set them apart from the rest of the house. The moulding also serves to help seal the edges of the window casing from air flow. You can affix this moulding around the window of just about any style of home.
