Mold Found in Attic

May 13, 2020 11:45:00 AM / by david sulock

Mold likes to grow where people don't like to be.  Attics are a common place where we find mold during inspections.  Home sellers are often surprised to find out that they have mold in their attic.   Attics are not heated nor air conditioned, which means both humidity levels and temperature fluctuations are very varied and due to these conditions mold will find a home to grow.

All photos you will see on this page are from the same attic, each area of mold grew because of different environmental variables.

The mold you see in this photo was caused by the bathroom vent leaking moist air onto the wood sheeting.

The mold in this photo was from natural humidity over the years.

How do you correct attic mold.  First you need to identify the moisture source and correct the issue.  Attic mold may be caused by insufficient ventilation or air leaks from finished spaces.  Some bathrooms will vent moist air into the space creating an environment for mold growth.


Remediating mold rarely ever requires replacement of the wood surface but rather thorough cleaning of the wood, application of a fungicide and lastly a preventive coating that warranties that the wood will not allow mold growth.



This photo shows an attic that has been remediated.  The white coating you see is fungistatic, meaning it inhibits mold growth.  These coating provide the owner a warranty that mold will not grow on the treated surface.
