The answer to 'why is my hardwood floor odor' is that there are several common causes, including spills, pet accidents, moisture issues, and bacteria growth. Hardwood floors can develop unpleasant odors due to trapped liquids, organic matter, or microbial growth. The symptoms may include a musty, sour, or ammonia-like smell that doesn't go away with regular cleaning.
In many cases, the odor can be addressed through thorough cleaning and drying of the floor. This may involve using a wood floor cleaner, baking soda, vinegar, or other deodorizing agents. However, if the odor persists or is caused by more serious issues like water damage or mold, it's best to call in a professional hardwood floor cleaning and restoration service to properly diagnose and resolve the problem.
