How to Install Rosette Door Trim

Lisa Wampler

Installing rosette door trim can help increase the appearance of doorways. Rosettes are decorative corner pieces that fit on each side of the door. Rosettes have been used for hundreds of years in many different styles of homes.

Adding rosettes does not add too much to the process of installing door trim, but the outcome might look better than installing trim without them.

  1. Use a pencil to mark 1/8th of an inch above the left door jamb.

  2. Measure the distance between the top of your plinth block or the floorboard and the mark made on the wall with a tape measure. Cut the left and right door trim to your measurement with a miter saw or a handsaw and a miter box.

  3. Drill 3/32-inch holes in the left and right side on each piece of wood trim about 10 inches apart.

  4. Pre-drilling these holes will keep the wood from splitting when you drive nails into it.

  5. Place the wood trim on top of the plinth blocks or on the floorboard and line the edge of the trim up with the edge of the door jamb. Fasten the trim to the wall using 2-inch trim nails and a hammer. Complete this task on both sides of the door jamb.

  6. Drill a hole in each corner of each rosette with the 3/32-inch drill bit. Center both rosettes on top of the vertical trim pieces and fasten them to the wall using 2-inch trim nails and hammer.

  7. Measure the distance between each rosette with your tape measure and cut a piece of trim to match your measurement. Use your miter saw or a handsaw and a mitre box to make the cut.

  8. Place the trim between the rosettes and line the bottom edge of the trim up with the top of the door jamb. Secure the trim to the wall with 2-inch trim nails and a hammer.

  9. Fill the nail holes and any gaps with wood filler and putty and allow it to dry before painting or staining the wood.
