Treating mold under a carpet can be a daunting task for many homeowners. If you suspect mold lurking beneath your carpet, immediate action can save your home from further damage. The subfloor is crucial because it supports the carpet and ensures the structural integrity of your home. Let’s dive into the necessary steps to effectively treat the subfloor under a moldy carpet.

1. Assess the Damage
Before proceeding, it is important to assess the situation. Look for signs of mold such as a musty odor or visible discoloration on the carpet surface. Consulting a professional may be necessary if the mold covers a significant area.
2. Remove the Moldy Carpet
After assessment, remove the moldy carpet carefully. Wear protective gear like gloves and a mask to prevent inhaling spores. Cutting the carpet into smaller, manageable pieces can facilitate removal.
3. Dispose of the Carpet Safely
Moldy carpets should be handled with care. Double-bag the pieces in heavy-duty garbage bags and dispose of them according to local regulations.
4. Inspect the Subfloor
Once the carpet is removed, conduct a thorough inspection of the subfloor. Look for any signs of mold, moisture, or damage.
5. Clean the Subfloor
To remove mold, clean the subfloor using a mixture of water and detergent. Ensure you scrub the area well, and then dry it completely. You may also want to use a HEPA vacuum to clean moldy residues.
6. Apply a Mold Inhibitor
After cleaning and drying, apply a mold inhibitor to prevent future growth. This step is vital for maintaining a mold-free environment.
7. Ventilate the Area
Good ventilation is essential to prevent mold recurrence. Use fans or a dehumidifier to ensure good air circulation until the area is completely dry.
8. Prevent Future Issues
Consider installing a moisture barrier before laying down new carpet. This step helps in keeping moisture from seeping into the subfloor.

Once everything is clean and dry, consider options for new flooring that might resist mold better. Check out these flooring alternatives for mold prevention.
