Extended low-humidity indoor environments can cause excessive shrinkage in the wood resulting in loose floor connections. Excessive high-humidity indoor environment can cause expansion in the wood resulting in pressure-related floor squeaks. The homeowner must maintain indoor humidity levels to prevent excessive drying or expansion of materials. A permanent squeak-free floor may not be attainable.
