The answer to 'why is my floor water damage' is that there are several common causes, including leaks, flooding, poor drainage, and excessive moisture. Symptoms may include discoloration, warping, or a spongy feel to the floor. Solutions depend on the severity and source of the damage, but may involve drying the area, repairing leaks, or replacing damaged flooring.
For minor water damage, homeowners may be able to address the issue with DIY methods like fans, dehumidifiers, and mopping up excess water. However, for more extensive damage or if the source of the water is unclear, it's best to call in a professional water damage restoration company. They can properly assess the situation, identify the root cause, and take the necessary steps to fully dry out and repair the flooring.
