How to control condensation

You can control condensation by using a professional condensation control company on However, if you would prefer to attempt controlling condensation yourself, you can do so by:

  • Hanging clothes to dry outside rather than inside.
  • Keeping the indoor temperature fairly continuous.
  • Refraining from drying clothes over radiators.
  • Making sure your tumble dryer is well-vented and you empty the condensate frequently.
  • Maintaining extractor fans and making sure they provide enough airflow.
  • Not switching off or disabling an extractor fan.
  • Keeping furniture away from the walls.

What factors control the rate of condensation?

The factors controlling the rate of condensation include:

  • A room’s indoor temperature.
  • Outdoor temperature.
  • The air’s water vapour content.
  • Variation of inside and outside temperature.

Do condensation control units work?

Yes, condensation control units work extremely well to reduce condensation in a home. A condensation control unit is fitted to an external wall and works by emitting fresh, filtered air into your home. When the weather turns cooler, the automatic temperature sensor kicks in, causing the unit to gradually mitigate the incoming air so it decreases the loss of heat. A condensation control unit works to:

  • Efficiently dilute and displace the damp air within a property.
  • Prevent the occurrence of mould growth.
  • Improve air quality.
  • Supply fresh, filtered air.
  • Remove moist, damp air via passive ventilators.

Using a condensation control unit is good in circumstances where an owner does not live at a property and tenants reside there. A professional condensation control engineer can install the unit to make sure it works properly. Often, one can be set up so there is no need for anyone else in the property to manually control it.

How to install a condensation control unit?

To install a condensation control unit, you will receive the correct user instructions with the unit or you can seek the help of a condensation control specialist.
