Remediation is the cleanup of the mold infestation or growth. Often we are asked the question, "If I have mold can I clean it up myself or do I need a professional?"

Essentially it depends on the type(s) of mold, the aggregate amount of colonization and size of the area. If you have less then 10 square feet of mold that are a type 1 allergen, generally these can be cleaned by the average homeowner using a detergent solution. In order to determine what type of mold you have, it is recommended to first have the proper sampling and laboratory testing performed by a qualified company.


It is not recommended for individuals untrained in bio-containment abatement procedures to attempt to perform remediation on molds with an aggregate area of contamination of 10 square feet or more. Regardless of the type of the mold and size of impacted area, if the mold is a known to be toxic or pathogenic, than a professional abatement company should be considered.

Homeowners performing any surface cleaning should observe proper safety precautions such as the use of surgical latex gloves, goggles, and a N95 rated mask. If using a weak bleach solution, never mix with any compound other than water. Thoroughly dry the affected area(s).

Because many molds can be both pathogenic and toxic, and to ensure your health and safety and the spread of mold spores, it is recommended that you follow guidelines of an approved authority. The New York City Department of Health & Mental Hygiene Bureau of Environmental & Occupational Disease Epidemiology offers suggested guidelines on Assessment and Remediation of Fungi in Indoor Environments.

The Environmental Protection Agency (EPA) is yet another good source. At the EPA website you can find both suggested guidelines, as well as, registered products to use for remediation.

Before any remediation can be successful, the first step is to identify and correct the source of water or moisture. If you don't the mold will grow back. It only takes 24 to 48 hours.
