This article discusses how to recognize mold that may be harmless, or cosmetic only in importance in buildings. We look for mold in buildings not only where mold is visible but also by context: where do we see leak stains, or where do we see building practices most likely to have produced a hidden leak or moisture problem? Ice dam leaks in walls, hidden plumbing leaks, roof spillage by the foundation, are all common clues that often track to a wet building wall or ceiling cavity and from there to a hidden mold problem which may need to be addressed.

How to Recognize Harmless Cosmetic Molds and Other Low-Risk MoldsReaders should be sure to also review more details about harmless mold at HARMLESS BLACK MOLD. On occasion some visible mold can be determined to be harmless and "cosmetic" old mold that was present when the building was constructed. While it is always possible that additional more harmful molds are present in addition to the cosmetic mold, if there is no leak history nor any other evidence of mold growth in a building and if there are no health or building-related occupant complaints, the identification of the cosmetic mold described here might be accomplished by visual inspection alone, saving on more costly professional mold tests. So sometimes the mold in your house might be only a cosmetic concern. "Bluestain" or Ceratocystis/Ophistoma is common on framing lumber and we often find it in attics on the under side of roof sheathing. Unless it's in finished portions of living space where it creates a cosmetic problem, no particular action needed to address this black mold. Detailed advice about spotting harmless black mold including how to determine by visual inspection alone whether or not you're probably looking at one of these common framing lumber cosmetic molds is at HARMLESS BLACK MOLD. Warning notice about Cleaning Up Mold YourselfGuidelines defining what's a "large amount" of mold and what's reasonable for a
homeowner to handle have been published by several states including New
York and California. Links to some key documents describing mold cleanup and mold remediation procedures
are at MOLD CLEANUP GUIDE- HOW TO GET RID OF MOLD People who are allergic, asthmatic, infant, elderly, immune-impaired, etc., should not disturb mold and should not be in the area where mold remediation is being performed. Consult with your doctor, health department or other professional before tackling this job yourself. Frequently Asked Questions (FAQs)...
