Mould can be a major problem in your home. Aside from damaging fabrics and causing stains to form on paint and furniture, it can also have a negative effect on your health. As such, mould problems need to be dealt with quickly, effectively, and correctly. While it might be tempting to simply paint over mould and hide the problem, this will not solve the underlying issues, and before long, you will have the same signature patches of black growing on affected walls and ceilings
Moulds grow in damp conditions where their spores can settle and grow into colonies. In homes, the most common cause of these mould supporting damp patches is condensation – where moisture in the air settles onto porous surfaces and is allows to soak in.
Mould spores float freely in the air, and are part of nature, but they will only grow in situations where there is little airflow and spores have the moisture that they need to thrive.
It is impossible to prevent mould spores from entering your house completely as they are microscopic and carried on clothes as well as on the air itself, but you can take steps to prevent them becoming a problem by making your domestic environment unfriendly to them
Painting over a patch of mould will not kill it. While the majority of mould is on the surface, the colony extends a little way into the underlying material from where it can draw nutrients. Some of the mould colony will survive after paint is applied, and before long, it will penetrate through the new layer of paint and start to show on the surface. In some cases, painting over mould can be a bad thing as it allows the mould to grow undetected and spread across a larger area of your home while hidden behind that thin top layer of paint.
Even cleaning affected walls cannot completely kill off the problem altogether. While bleach may deal with the current infestation and remove it, unless you remove the ability of mould to thrive in the future, it will always come back and grow in the same areas where it has the moisture to survive, and static air that allows the spores to settle and start a colony.
To prevent mould problems coming back, you need to remove the underlying problems of stale air and dampness, and this means a combination of improving air flow and reducing the amount of moisture in your air.
Ensuring that you use extractor fans when cooking and bathing is a small step towards reducing the presence of condensation, but in order to properly address wider issues with air flow through your home, you should consider a whole house ventilation system such as PIV (Positive Input Ventilation) which draws air in from outside and then distributes it to all rooms of your home and keeps your air fresh.
