Indoor Air Quality (IAQ) and Mould Issues During Winter

Now that the winter months are upon us, mould can be an issue for some homes and buildings. Due to the colder temperatures and use of heaters, as well as sealing up of homes and rooms, moisture builds up around windows, sills, corners of rooms, bathrooms and laundries. The combination of moisture in porous surfaces such as wood and plasterboard where the moisture content is above 40% and organic material means that significant mould growth can be supported.

The first thing that a householder or facility manager will notice is the blackening of ceilings and walls which will deteriorate and may be associated with odours or at least, a perception of stale or musty air in the affected areas.

The best way to prevent mould growth is by using extraction fans and good air circulation with ventilation or opening of windows. If condensation occurs on windows or sills, dry the surface and try to find the source of the water such as damaged or blocked gutters or a damaged roof.

When mould is present, it is important to act quickly to clean the affected area with an appropriate mould cleaner and address the source of the water egress. Extensive indoor mould contamination can become problematic for people susceptible to respiratory problems or those with serious health problems; some people may even develop allergic reactions to the mould.
