Damp can be caused by poor maintenance, ill fitting building materials and poor ventilation. Damp areas can be found on walls, doors, floors, around windows and pipe-work in any home. For example, a wet patch found on the top of a wall may be the result of a leaking gutter outside.
Rising damp only happens at ground floor levels as the moisture drawn up the wall comes from the soil in the ground. Decaying skirting boards, crumbling plaster and tide marks on walls all identify a possible problem with rising damp. As this type of damp is easy to misdiagnose, it is advisable to get expert advice.
Penetrating damp is caused by water entering a property through walls, floors and ceilings, causing external construction damage to guttering, rendering and wall joints. It could be the result of a burst pipe or a problem with plumbing. Damage to plastering, decaying timber and watermarks on masonry all indicate a potential problem with penetrating damp.
Condensation is arguably the most common form of dampness with 1 in 5 homes in the UK affected. Tell tale signs of condensation include streaming windows and walls, deterioration in decoration such as discolouring of window panes and eventually the growth of black mould.
