Mould removal

Mould is a sign your house is damp. It can cause health problems for your family and should be removed regularly. Check hidden areas like wardrobes, under carpets, and behind curtains and furniture.

How to remove mould

You can remove mould easily without using a professional.

Things to consider first

  • Keep children, allergy sufferers and people with a weakened immune system out of the room during mould treatment.
  • Air the room well until all fumes have evaporated.
  • Keep all chemicals well away from children, and open flames or fire.
  • Do not smoke or use candles whilst handling methylated spirits or isopropyl alcohol.
  • Treatment may discolour some materials, so may not be appropriate for all surfaces. Refer to manufacturer for further advice.

Steps to remove mould in your house

  1. Apply methylated spirits or isopropyl alcohol (available from supermarkets and hardware stores) to the area using a brush or spray bottle.
  2. Let it set for 30 minutes.
  3. Re-apply methylated spirits or isopropyl alcohol.
  4. Let it set for a further 30 minutes.
  5. Wipe with a clean cloth and methylated spirits or isopropyl alcohol.
  6. Throw the cloth in the rubbish when finished, to avoid spreading mould spores.

Vinegar can be used as an alternative, however it does not kill all types of mould, and any residue left behind may encourage more mould growth in the future. Follow the same procedure above and rinse well with water at the end.

Bleach and commercial mould removers can also be effective, but release harmful fumes into your home over a long period of time.

Recurring mould

If mould returns after repeated removal, humidity in your house is probably too high.

Mould on walls or ceilings that reappears within a couple of weeks may be caused by dampness inside the wall or ceiling cavity, with the mould growing from the inside out.

Consult a registered or accredited building surveyor for advice.
