Replace a floorboard
Bellow are pictures and descriptions of how to replace a floorboard in a hardwood floor. This method only works if the floor is either glued to the sub floor or nailed to the sub floor. I get called out a few times a year to replace damaged floorboards. In the pictures below the heavy glass light fitting had fallen on the floor after two years of hanging on with one screw into plaster board. The floor is an engineered floor but it makes no difference if the board is a solid wood board when we have to replace a floorboard.
If the floor is floated (where the tongue and grooves are glued together) this method will not work. This is one of the many reasons why we never float wood flooring unless we absolutely have to.
