Hollow Door Fix: New Bottom for Hollow Core Doors

hollow-core DOOR

Can you trim a hollow core door?

Yes! But the question then becomes, what do you do to re-close the bottom? We’ve got a solution that is easier than reusing the wood block from the piece you cut off.

Hollow door fix

The next time you have to shorten a hollow-core door, try replacing the bottom rail with expanding foam instead of wood.

  1. Cut the door to the right length.
  2. Clamp stiff boards to both sides of the bottom (as shown).
  3. Fill the hollow door bottom with expanding foam insulation.
  4. After the foam dries, trim off the excess with a utility knife and rehang the door.
