Q: How do I install crown molding when the nails won’t reach the ceiling joists?
A: Due to the direction of the ceiling joists, two walls in the room won’t have the same solid framing for secure fastening. One trick is to predrill and drive a 16D nail at an angle to hit the framing at the top of the wall. Another option is to cut and install triangular filler blocks that fit flush behind the crown molding. Nail the filler blocks into the wall studs, and then nail the crown molding over the blocks.
