How do I keep my hardwood floors from separating?

Use a humidifier in the winter months to keep your home’s relative humidity stable and prevent large gaps in your wood floors. Exhaust fans and dehumidifiers should be used during the summer months to keep the air dry. Wood filler can be used to fill gaps smaller than 3/16 of an inch wide.
