Damp and mould in rented homes
One of the most commonly reported housing disrepair issues. Here's what it typically involves and how to document it.
Moisture that forms when warm, humid air meets a cold surface — often on windows, in corners, or behind furniture placed against external walls.
Moisture that enters a property from outside, often through a defect in the roof, walls, guttering or window seals.
Visible black, green or white growth on walls, ceilings or fabrics, often appearing after prolonged damp or a leak.
Common signs
- Visible mould on walls, ceilings, window frames or fabrics
- Persistent condensation on windows or cold surfaces
- Damp patches that don't dry out
- Water staining on ceilings or walls
- A musty or damp smell in a room
- Peeling paint or wallpaper
- Recurring moisture after a leak has been "fixed"
- Poor ventilation — extractor fans not working, trickle vents blocked
