Why October Gaps Appear Before Winter

October is when many floors begin to change before anyone expects them to.

Heating systems are switched on as outdoor temperatures drop, but interior humidity control often lags behind. The result is a rapid drop in indoor relative humidity over days or weeks—not the gradual seasonal drying that defines winter.

This is why gaps sometimes appear suddenly in October, even in buildings that performed well the previous winter.

These are not winter gaps.
They are rate-driven contraction gaps, caused by how quickly moisture leaves the wood—not how dry the environment ultimately becomes.

At Huggins Wood Floor Specialists, October gapping is evaluated as a transitional condition. Understanding its cause prevents unnecessary repairs and avoids locking in damage before the floor has reached its true seasonal equilibrium.
