Hardwood Floor Repair - Remove & Replace Board
Buckled Hardwood Floors
A wood floor may require repairs far beyond the nail setting and sand just described. The main problems are deep stains, bad gouges, broken wood cupped or warped boards, and big bulges. The last three problems are usually from water leaks.
The most common repair technique is to cut out the bad flooring using a circular saw and a carbide tipped blade. The clean cut can be made more easily by nailing down a board temporarily as a straight edge. A carbide tip can cut through nails, but do not use expensive blades-the teeth may be chipped no matter how careful you are. Caution: Use safety glasses.
Next, pry up the bad section; repair the sub-floor, if necessary; and lay down new flooring surfaces.
If you are replacing tongue and groove flooring, there will be one joint that does not have all the nails concealed and does not have the lower lip of one groove ( unless the repair is next to the wall ). This board must be faced nailed ( drive the nails through the top surface of the board, recess them, and then cover with wood filler or putty).
For bulging floor areas, there is another, simpler technique that is appropriate only if the floor is being painted or covered. In this case, the carbide tipped blade cut relief joints, grooves that take away enough of the expanded wood that it can be nailed or screwed flat again; use drywall screws for this work. If you are painting, make sure that the screws are recessed enough to allow the putty a good grip.
