How to Cure Damp Walls

Updated February 21, 2017

Condensation is water vapour that develops in your home and can settle on your windows and walls. It can make your walls wet, which invites mould growth and the spread of other contaminants that might lower your home's value or cause health issues. Water vapour develops through a number of home activities and will turn to condensation when hot vapour hits a cold wall. Lower water vapour in your home to cure damp walls and condensation.

Cover pots when boiling water. This will lower water vapour in your home.

Turn on the ventilation far and shut the bathroom door after a bath or shower. Leave the door shut until the water vapour and steam dissipates. This should take about 20 minutes.

Avoid hanging wet clothes to dry inside your home. This will reduce the water vapour in your home.

Vent your dryer outside.

Fix your home's ventilation system or install ceiling fans throughout the home and exhaust fans in the bathroom.

Heat your home above 17.2 degrees Celsius. If the temperature is lower than that, it will turn the water vapour to condensation when it hits a cold wall.

Install a dehumidifier in your home if the water vapour and damp walls are still present.

Install double- or triple-paned windows in your home to keep the home warmer.
