Damp, mould and condensation
Damp can:
- cause mould on walls and furniture
- make timber window frames rot
- encourage the growth of mould and mites, and
- increase the risk of respiratory illness.
Damp can be caused by condensation, so reduce condensation to reduce the risk of damp. We have provided some tips to help you
Kill and remove mould
- Wipe down walls and window frames with a fungicidal wash or mould spray.
- After treatment, redecorate using a good quality anti-fungal paint to help prevent mould from recurring.
Ventilate to remove moisture
- Do not block ventilators or chimneys
- Ventilate bathrooms or kitchens and close the doors when these rooms are in use to prevent moisture spreading.
Produce less moisture
- Cover pans and do not leave kettles boiling
- Dry washing outdoors, or in a bathroom with door closed and window open.
Heat and insulate your home
Condensation is less likely when the house is warmer.
- Insulate your loft
- Consider cavity wall insulation (check if building regulations approval is required)
- Consider secondary and double glazing
- In cold weather, keep low background heating on all day, even when there’s no one at home.
