Cracks and separations

This can occur between boards when homes are heated in the winter, humidity (Relative Humidity RH) levels can plummet, boards can shrink and spaces appear between the boards as the wood loses moisture content. Some of these variations are seasonal and will close up on their own when the weather (and related RH) changes and moisture returns back to the air. Monitoring the room’s temperature and RH level, then taking corrective action, can also minimize seasonal shifts in the wood floor. As an example, homeowners can add moisture to the air during dry winter months by installing a humidifier in the furnace.
