The answer to 'why is my hardwood floor moldy' is that mold growth on hardwood floors is usually caused by excessive moisture or humidity. Mold thrives in damp environments and can quickly spread across wood surfaces. Common symptoms include discoloration, musty odors, and visible mold patches.
To address this issue, it's important to identify and address the root cause of the moisture problem. This may involve fixing leaks, improving ventilation, or addressing high humidity levels in the home. DIY solutions like cleaning the affected area with a diluted bleach solution can help, but for more severe mold infestations or underlying moisture issues, it's best to call in a professional mold remediation specialist.
