If you have a fireplace in a home, moulding is installed around the base of the hearth area. The wood flooring installs up to the edge of this moulding. It provides a transition area between the brick and wood floor just like a threshold provides a transition from wood flooring to carpet, or linoleum to carpet. Installation requires basic tools and preparation. Planning ahead makes the installation easier.

  1. 1

    Measure the width of the moulding from one end to the other using a tape measure. For simplicity sake, we will assume the moulding is four inches wide.

  2. 2

    Measure four inches from the edge of the fireplace brick at the centre and corners. Mark off four inches on the under flooring with a pencil.

  3. 3

    Set a chalk line across the front of the fireplace so it lines up with each mark and snap the chalk line. This assists in your floor installation later.

  4. 4

    Measure the distance of the fireplace. Mitre cut a moulding piece at a 45-degree angle with a mitre saw, so the inside (shorter side) matches this distance.

  5. 5

    Measure the sides of the fireplace from the front corners to the wall. Mitre cut two more moulding pieces to match this measurement at a 45-degree angle on a mitre saw.

  6. 6

    Fit the moulding pieces around the hearth. Make sure each fits tightly. If not, hand sand the pieces until they fit. Recut pieces that are more than 1/4-inch off measurement.

  7. 7

    Hammer a finish nail through both ends of the top of the moulding pieces into the floor boards, once pieces are perfectly fit to the hearth. Use a nail punch to recess the finish nail.
