Noticed mould growing on your walls and thought about reaching for the bleach or vinegar? Well, don’t as they will not kill mould.

Read our helpful hints and tips on how to kill and get rid of mould effectively.

What is mould?

Let’s get to the root cause of the problem. Mould spores are normally inert in the substrates of buildings and only grow when in contact with excessive moisture in the air that is caused by day-to-day activities, such as cooking, showering, drying wet clothes. This is often exacerbated by cold surfaces and environments. When the moisture gets trapped from poor ventilation, condensation forms on cold surfaces, which can result in droplets forming on exterior walls and ceilings.

Moisture which is held in the atmosphere and forms condensation is not pure water. It contains fats and greases from cooking, washing, bathing etc and general household dirt which both waters and feeds the mould spores.

How to prevent condensation

To prevent mould growing or forming, you can take some simple steps to prevent condensation forming:

Keep inside temperature consistent

  • Wipe cold surfaces
  • Open windows when warm outside
  • Close kitchen and bathroom doors
  • Try not to dry clothes inside
  • Maintain and use extractor fans
  • Add insulation

If you’ve tried all the above and still noticed condensation forming, dehumidifiers could be the solution. Dehumidifiers help to control moisture in the air, which can stop further growth of mould. Take a look at our dehumidifier range here.

However, if you already have mould, you’ll need to treat it and treat it soon.

How to kill mould

Once you’ve found the source of the condensation which is normally a lack of ventilation or poor insulation and/or heating and addressed the problem you can start to kill the mould. You should only use treatments that are approved by the Health and Safety Executive for killing mould and carry an HSE registration number. You should be wearing protective equipment, such as goggles, gloves and a mask for the nose and mouth, to protect yourself from mould spores.
