contending with a fireplace
mark underside of board for wires
Put Tape on the Board
Note: Installing a floor can be difficult if there's a fireplace in the living room. In this case, a floor has to be custom fit.
Right next to a fireplace there could be some in-floor heating wires that stick up from the subfloor and a curved hearth of the fireplace to contend with (Image 1).
Mark the underside of the board where the wires hit and put tape on top of the board to show where to make the cut (Image 2).
