Frequently asked questions

Do you treat the mould spores in the air as well as the visual mould?

Yes. Our experienced technicians are able to treat the visible mould as well as airborne mould spores using our specialist air filtration systems.

What causes mould formation?


  • Leaks can cause mould to form by providing the necessary moisture, darkness and organic material. Mould will also grow in areas where there is a lack of air circulation. Mould spores are present in the air and when they land on a surface that is wet, they will start to grow.

Condensation and humidity

  • Condensation and humidity can also lead to mould growth. Warm, moist air holds more water content than cool, dry air. If you have too much humidity in your home or workplace, mould can begin to grow on a variety of surfaces - from hardwood floors and walls to paper. Mould may even grow on porous materials such as carpets and fabric.

Rising damp

  • One of the most common causes of mould growth in buildings is rising damp. Rising damp is a problem that occurs when water rises up through the foundation or wall of a building, often as a result of poor drainage or breached damp proofing. This can cause mould to grow on the walls and ceilings, as well as on furniture and other belongings that are in contact with mould damaged surfaces
  • Rising damp is a common problem in older buildings, where the water table is high or there are cracks in the damp proofing membranes. As the water rises up through the foundation and walls of the building, it can cause mould to grow on the walls and ceilings. This type of mould often appears as black or green patches and can be difficult to remove with traditional methods.
