How to prevent mould

Mould is a type of fungus that lives in warm, moist conditions. It grows in damp, dark and poorly ventilated areas at home like bathrooms and kitchens, or cluttered storage or basement areas.

Things that help stop mould

There are a number of steps you can take that will prevent mould growing in your home.

  • Open windows and doors to let fresh air in and reduce humidity.
  • Open blinds and curtains during the day to let sunlight in.
  • Turn on the exhaust fan or open a window in the bathroom, laundry and kitchen to get rid of steam.
  • Wipe down tiles to clean off soap scum that mould feeds on.
  • Wipe away any moisture on your windows and walls to keep the inside of your home dry.
  • Dry your clothes and shoes before you put them away.
  • Air out wardrobes and cupboards regularly.
  • Use moisture absorbers in basements, wardrobes and closed-off rooms.

The best way to stop mould from growing is to let in fresh air and light, clean regularly and control moisture in your home.

Things that help mould grow

  • Indoor plants like ferns need moist air, so choose low-water varieties like succulents for around the house.
  • Fish tanks add moisture to the air, especially tropical fish tanks.
  • Portable heaters (kerosene or unflued gas heater) give off moisture and gas, always ventilate the area.
  • Leaking taps and pipes encourage mould, especially in closed areas like cabinets.

Rising damp is moisture from the ground travelling up into your home through the bricks or stone in walls. If you suspect that rising damp is causing a mould problem in your home, report it right away. If you live in community housing, contact your housing provider to report severe mould problems.
