Homeowner’s Checklist: How to Keep Mould Out of Your House

Mould prevention doesn’t stop with building techniques—it also depends on daily habits and regular maintenance. Even a well-built house can develop mould if homeowners don’t actively manage moisture indoors and outdoors.

Improve Airflow

  • Open windows daily.
  • Use ceiling fans or portable fans to reduce stagnant air.
  • Leave space between furniture and walls to prevent condensation build-up.

Manage Indoor Moisture

  • Avoid drying clothes inside unless ventilation is good.
  • Cover cooking pots to reduce steam in kitchens.
  • Fix leaking taps or plumbing quickly.

Protect Exterior Walls

  • Apply plaster or render for water resistance.
  • Use breathable exterior paints that allow moisture to escape.
  • Keep plants, firewood, and debris away from walls.

Roof and Gutter Maintenance

  • Clean gutters before rainy season.
  • Repair broken roof sheets immediately.
  • Ensure downpipes lead water away from walls.

Regular Cleaning

  • Wipe away condensation on windows and walls.
  • Remove small patches of mould early with bleach or vinegar.
  • Repaint damp-prone rooms (like bathrooms) with mould-resistant paint.
