What causes squeaky floor boards?
Some squeaking in hardwood floors is normal and to be expected. While squeaks in flooring can be caused by improper installation, they are most often the result of normal aging. Over time, hardwood expands and contracts with natural seasonal changes, from humid summers back to dry winters. As the wood expands and contracts, fine cracks develop. As the wood swells with humidity, the boards can rub together, causing minor squeaking noises.
