Damp and mould

We’ve created some helpful guidance to reduce condensation and stop it from developing into damp or mould in your home.

If you notice any signs of damp or mould, please let us know through our customer portal or call us on 01883 770250.

Condensation we all get it

Condensation is something most households experience. It happens when warm, moisture-laden air, for example steam from cooking or boiling a kettle meets a colder surface or cooler air, such as window glass or the frames around external doors and windows. When the warm air cools, it can no longer hold the moisture, which then settles as small water droplets.

It can also develop in places where air movement is limited, including inside cupboards or behind furniture positioned against external walls. Because warm air can retain more moisture than cold air, homes that are cooler are more likely to see moisture released onto cold surfaces. Condensation is most commonly found in kitchens, bathrooms and bedrooms.

In newly built homes, condensation may also occur as construction materials such as plaster and mortar gradually dry out during the early period of occupation.

How to prevent condensation from leading to damp and mould

  • Improve ventilation by opening windows for a short period each day, even in cooler weather.
  • Whenever possible, dry clothes outside rather than indoors.
  • If clothes must be dried inside, keep windows open to allow moisture to escape, use a clothes airer, or a condenser tumble dryer that collects water in a container.
  • Reduce moisture in the air by opening a window or using the extractor fan while cooking in the kitchen, and during baths or showers in the bathroom.
  • Make sure extractor fans and other ventilation systems in kitchens and bathrooms are working correctly. Please report any faults to us.
  • When filling a bath, run the cold water first and then add hot water to limit steam.
  • After showering, wipe excess moisture from tiles, screens and other surfaces, and open a window to help the room dry out.

Understanding different types of damp

There are several forms of damp, each caused by different issues:

Penetrating damp

This occurs when water passes through external walls, often as a result of leaks, damaged brickwork, or problems with the roof. If you believe penetrating damp may be affecting your home, please contact us as soon as possible. We can arrange an inspection and identify the most appropriate repair.

Rising damp

This type of damp is less common but can usually be identified by a visible horizontal stain or “tide mark” on the wall. It is caused by moisture from the ground rising through the structure, typically due to a fault in the damp-proof course. If you suspect rising damp, get in touch with us and we will investigate promptly and take steps to put things right.
