Why Do Hardwood Floors Develop Cracks?

Before we delve into the process of how to fill cracks in hardwood floors, it’s essential to understand why hardwood floors develop cracks in the first place. Several factors can contribute to the formation of cracks, including:

Improper Installation

If hardwood flooring is not installed correctly, it can lead to gaps between boards, which may eventually turn into cracks.

Moisture Damage

Exposure to moisture, such as spills or leaks, can cause the wood to swell and contract, leading to cracks.

Insect Infestation
