Hardwood is a hygroscopic material that reacts to moisture levels in the air. Significant fluctuations cause planks to swell in high humidity and shrink in dry conditions. Homeowners should invest in a digital hygrometer to monitor indoor humidity. During dry winter months, use a humidifier to add moisture to the air. Conversely, during humid summers, utilize an air conditioning system or a whole-home dehumidifier to remove excess humidity. Additionally, ensure the flooring is properly acclimated before installation to help it adjust to the environment, and never use wet-mop cleaning methods, which introduce localized moisture to the wood.

How should homeowners protect hardwood floors from seasonal humidity fluctuations?
To protect hardwood from humidity, keep indoor relative humidity levels between 35% and 55% using a humidifier in winter and a dehumidifier or air conditioner in summer. Consistent climate control prevents excessive expansion or contraction that leads to gaps, cupping, or crowning.
