What does damp and mould look like?
Types of damp – condensation, rising and penetrating
Condensation is the most common type of damp in rented properties. It appears when there is an imbalance between heating, insulation, ventilation and humidity.
When moisture in the air makes contact with cold surfaces such as windows or cold walls, the water condenses onto the cold surface and black mould can grow around windows, behind furniture and in corners of rooms.
If the mould is not wiped regularly, mould will start to grow in small spots and could spread.
Your landlord has a responsibility to take action in relation to damp and mould growth in some circumstances. For example if your heating is not working it is your landlords responsibility to fix it.
Your responsibility as a tenant
You have a responsibility to manage moisture to reduce condensation by ventilating and heating your home. Everyday activities such as showering, cooking and drying clothes can cause condensation.
How to reduce condensation:
- Cover pans when cooking
- Use extractor fans in kitchens and bathrooms
- Close doors when you are cooking or showering
- Leave a gap between furniture and walls
- Dry clothes in well ventilated area
- Open windows at least once a day for short periods at a time to let warm moisture out, but do not leave them open all day as this can make your home colder which could make condensation worse
- Try to heat your home
Penetrating damp is caused by moisture entering into external walls for example through a crack, burst pipe or rain water. Penetrating damp can also get into homes from plumbing problems in the building.
Your landlord is usually responsible for carrying out works to fix penetrating damp.
Rising damp is when moisture rises up through a wall or floor. Usually because of a defect of the structure. Rising damp will require further investigation by specialist contractors.
Your landlord is responsible for carrying out works to fix rising damp.
When should my landlord take action?
Your landlord should fix the damp and mould problem if it is:
- caused by a repair that’s needed
- affecting your health
Report the damp and mould problem to your landlord. Your landlord is usually required to investigate and carry out necessary works to fix the damp and mould within a reasonable timeframe.
Who do I contact if my landlord does not take action?
A Camden Council environmental health officer will visit your home to carry out an assessment.
