How to install wood molding around a fireplace

Updated February 21, 2017

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.

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.

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.

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.

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.

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.

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.

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.
