mold and condensation

Hidden Mold Signs

Seeing and smelling mold are easy indicators that mold may be present.  Below are some often overlooked signs that can mean mold is or can become an issue. 

High Humidity

  • Humidity levels that are above 60% can lead to mold growth.  It is recommended that humidity stays between 30%-60%. Things that can increase humidity include: air conditioning and living near a water source.



  • Condensation is also a sign that the humidity levels are high.  It usually occurs on something cold like pipes or windows after water cold and becomes a liquid.  Condensation can be a problem because it can build up and create mold. If you have condensation, it is possible you have some mold.


Water Leaks

  • Leaks in pipes and roofs are common places that show signs of water damage.  There are also common in areas that are hidden from the eye (ie. behind walls, wooden beams).



  • Cold rooms that don’t get much ventilation (ie. basement) can have condensation and a great combination for mold to grow.  If you notice your basement is also damp, it may be a sign there is mold.



  • If a room is left for 24 hours, mold can begin to grow.  If the flooding was in a room with drywall, it can easily become moldy.  If the flooding was in a basement covered in cinder blocks, it is less likely to become mold.


Paint Cracking

When moisture is present, paint and wallpaper can begin to crack, bulge or warp.


Poor Ventilation

Be on the lookout for rooms that have poor ventilation.  It helps dry moisture and helps it retain in the room, much longer.


Past Water Problems

If the property has had flooding or water related issues in the past, it could have mold leftover.



Mold can grow on dust.  It can also transport mold spores to other areas if not cleaned properly.
