Can I clean mold myself and skip a contractor?
EPA states that if the moldy area is less than about 10 square feet, in most cases you can handle the job yourself. HomeAdvisor repeats the about 10 square feet DIY limit and notes $50 to $300 in gear is outside the professional average. Larger or contaminated jobs need a written remediation scope.
