Greenville, SC – Is Mold Fogging an Effective Mold Remediation Procedure?

Posted in: Industry News

Recently we have received several calls about mold remediation using a fogging spray as primary removal. One of the calls mentioned that they could still see the “dead mold” on the walls, and the other stated that they did not notice their respiratory symptoms getting better. In this blog, we will discuss why fogging is not recommended as primary removal for mold remediation.

What is Fogging?

In general fogging/misting is a method of atomizing water of other aqueous solutions into the air to control airborne and surface particulates. The Institute of Inspection Cleaning and Restoration Certification (IICRC) created the ANSI/IICRC S520 that is a procedural standard for the remediation of mold damaged structures and contents and states that Fogging / Misting is an acceptable practice during demolition and cleanup phases of remediation. This acts to control the dust and other airborne particulates in the air and help prevent cross contamination.

Should Fogging be used to remove mold?

According to the IICRC S520 Sec 12.1.7 “Remediators should not mist or fog disinfectants or sanitizers in an attempt to kill mold in lieu of source removal.” So what does this mean? Fogging may be used to kill the mold but, it may not solve the issue. If the mold is not removed the toxic and or allergic properties may still be present on contents or in the air. You will most likely also be left with the nasty staining from the mold. Remember the industry standard is removal.

How then should I remove the mold?

Always use a certified firm that is experienced in mold removal. Ask that an air sample be taken by an independent mold inspector pre-remediation to identify the issue. Next is to isolate and manage air flow of the affected area. Demo/ remove porous materials. Deep clean all surfaces in workspace. Once that is complete, post remediation air sampling to verify that the problem is taken care of.

Air Sampling

Air sampling is an important part of remediation because we are dealing with microorganisms that may not be visible except in large colonies. The IICRC Standard recommends that testing be done by an unbiased Indoor Environmental Professional (such as a certified mold inspector). Using a 3rd party for pre- and post-testing should be completed to ensure that the issue is resolved and there is no conflict of interest.

Whether you are in Greenville, Greer, Taylors, Simpsonville or anywhere else in the Upstate of SC and you are experiencing a mold issue, contact a mold remediation company that ensures the proper elimination of mold and minimizes the chances of regrowth.
