Mould Damage

Not all damp in structures is caused by building faults like rising damp, penetrating damp, plumbing leaks and water ingress. General household activities – such as drying clothes, cooking, bathing and breathing – can also introduce high levels of moisture into the property. When conditions are suitable, condensation begins to develop resulting in damp surfaces. There are many health risks associated with mould, click here to learn more.

For moulds to grow and reproduce they need a food source. These can be wallpapers, plasterboard, paint, some carpets, adhesives, wood fabrics and other organic materials.

Mould on tiled areas is not feeding on the tiles. It feeds on the biofilm residue from close proximity to things like soap and washing.

Moulds can begin to germinate between 4 and 12 hours. However, after germination, it takes time for the mould to develop, create spores and colonise. This can be 1-2 days for some moulds. It can be longer for others whereby 2-3 and 8-12 days can be attributed depending on the type. Mould doesn’t actually need to grow in the dark, it’s just that such places have been attributed with damp conditions, such as behind wardrobes.

Causes of damp and condensation

There are many causes of condensation and dampness in your home, however, the main cause is due to a lack of adequate air ventilation. Modern-day housing will often include increased insulation, draught excluders and double glazing, which have the unintended consequence of sealing in damp air. This allows the damp and condensation to sit and fester, creating a musty, mildewy and unhealthy environment.

Some other causes of damp within your home are:

  • Leaking pipes
  • Rising damp in basements or ground floors
  • Rain seeping in from the roof or around window frames
  • Faulty double glazing
  • Lingering moisture in the kitchen or bathroom

Developing Mould

The effects of damp and mould on humans varies greatly. It can be understood by how quickly each of us would get sunburn when exposed to the sun. However, occupants with reduced immune systems can suffer colds, flu-like symptoms and viruses as a result. The effect on humans can depend upon the amount of mould present. The type, the pathway to the person, how long they have been exposed and how sensitive the person also has an effect. It is equally important to understand what is causing the damp and how to effectively remove the mould.
