Hardwood Floor Cupping vs. Crowning

Floor Crowning

When moisture hit hardwood flooring wood expands and becomes susceptible to cupping and crowning – two common wood floor problems that, if not addressed properly and at the right time, can require costly sanding and refinishing to fix.

Cupping is a condition where wood board becomes concave – edges high with a center that dips low. As wet hardwood flooring expands, cupping can occur.  It is brought on when the bottom of the wood flooring remains wetter than the top surface. When cupping occurs, it’s important not to rush quickly into sanding.

Crowning –the opposite of cupping – occurs when the top edges of the board are sanded off too early and become lower than the rest of the board as it returns to normal moisture levels. Sanding the floor to remove crowning should only begin once drying measures are complete and normal moisture levels have been achieved.
