What can I do in moldy wall?
remove it. carefully. or get a mold remediation crew in to d it.
Hi there, look for mold killer spray at your local hardware store and spray on the mold. Mold usually forms where there's no air flow so try putting a fan or dehumidifier in the room or area.
How bad? Chances are you have mold behind the wall which can be deadly. Get a mold remediation team out to assess the situation.
Check with Lowe's for a mold killing product. My husband did a job for a lady who had a flooded house and it works great. Also, make sure you wear a respirator and not just a mask.
