A low view into the corner of a dining room where deep stepped white crown molding meets pale blue walls and a fresh ceiling

Crown molding installation

Molding at the ceiling line, cut at compound angles and coped at the corners.

What this covers

Crown molding sits at an angle between wall and ceiling, so every cut is a compound angle and every corner is tested against walls that are rarely square. The carpenter chooses a profile sized to the room, installs backing where needed, cuts and copes each piece, nails it to studs and ceiling joists, and fills and caulks for the painter. Built-up crown stacks several pieces for a larger profile.

When to call

  • A dining room, living room, bedroom or hall that wants a finished ceiling line.
  • A room where the ceiling and wall meet unevenly and a crown would hide it.
  • Trim removed during a ceiling repair that needs replacing.

Questions people ask

What size should crown be?

Taller ceilings take larger crown. An eight-foot ceiling usually suits a modest profile; higher ceilings can carry built-up crown.

Why are the corners coped?

Mitered inside corners open as the wood and house move. A coped joint stays closed.

Can crown go on cabinets?

Yes. Cabinet crown is a common finish on upper cabinets and is fitted the same way.
