How to identify condensation mould and mildew
Condensation can create black spot mould (aspergillus niger)
and this is one of the easiest
moulds to identify. Condensation mold is usually groups or clusters of black spots, these can over time link up to
form continuous areas of black mould along cold areas of walls, often in places of little air movement such as
behind chairs/furniture, in corners of rooms up walls and along ceilings.

Black spot mold growing on dot'n'dabbed plasterboard where the
dabs have caused a thermal bridge from the cold outside wall through to the internal surface. The now cooler
surface has created a lower dew point where condensation has occurred and lead
to mold growth in the exact shape and position of the dabs behind the
plasterboard.
