What’s the Difference?

Damp happens when water sneaks into your home—either through a fault like a damaged roof or rising damp from the ground.

Mould shows up when there’s too much moisture in the air. It’s often caused by poor insulation, not enough heating, or stale air that can’t circulate properly.

Condensation happens when warm, moist air hits cold surfaces, turning into little water droplets.

Things like drying clothes indoors, cooking without lids, or not opening windows can lead to extra moisture in your home. If it sticks around on windows, walls, or furniture, mould can start to grow.

How to keep condensation and mould away

Here are some simple things you can do to stop mould before it starts:

Cut down on moisture:

  • Empty tumble dryer water trays regularly and keep lids on pans while cooking.
  • Dry clothes outside if you can—it makes a big difference.

Let your home breathe:

  • Open your bedroom windows for 15 minutes every morning to get fresh air flowing.
  • Keep trickle vents (those small vents on your windows) open.

Keep the heat steady:

  • Aim for a comfy, steady temperature (19–21°C).
  • Leave doors slightly open to help warm air move around your home – except when cooking or showering!

Give your furniture some space:

  • Don’t push furniture right up against walls. Leave a little gap (about 3 inches) so air can flow around it.

Be mindful in steamy rooms:

  • When cooking or showering, close the door to keep moisture in one spot and run the extractor fan or open a window.

Tips for a cosy, mould-free home

Drying clothes: Avoid drying clothes on radiators (it fills the air with moisture). Instead, use an airer in the bathroom with the radiator on, a window ajar, and the extractor fan running.

In the kitchen: Pop lids on pans, use your extractor fan, and open a window while cooking. Let the fan run for a while afterward to clear the air.

Ventilation is key: Open vents, clean them if needed, and try cross-ventilation by opening windows on opposite sides of your home to create airflow.
