Moulding Styles


Front doors at The Gamble House. Simplicity is the hallmark of Craftsman-style trim. Although each molding is simple, the combined effect gives the room a distinctive, handcrafted look.

 

 

Use Reveals and Avoid Flush Edges

Wood moves -- as it dries out, as the house settles, as you cut it and as you're nailing it up. It's almost impossible to get flush edges to stay that way. That's why, for example, carpenters usually step casing back from the edge of door and window jambs. Stepping trim back to form reveals causes shadow lines and creates different planes that make it harder for the eye to pick up discrepancies.

Wood moves, so it's practically impossible to keep flush edges flush. Instead, offset edges from each other, such as the casing from the jamb. And use boards of different thicknesses as with the head casing and the leg shown here. This way, they can swell and shrink unnoticed.

Moldings hide the gap: Floorboards don't have to be a uniform distance from the wall. As long as the base/shoe molding covers it, the gap can vary.

Avoid exposing end grain
Don't show end grain. It absorbs paint and especially stains differently than flat grain. If a piece of molding must end abruptly, cut a return for it.
