Rising dampness as its name suggests rises from the ground and can be found in buildings which do not have a damp proof course present. However, rising damp can also occur in buildings which have a damp proof course present but may have become damaged or failed due to a number of possible reasons. ‘Bridging’ is a common cause of failed damp proof courses. This is where earth or stored items leaned against a wall allow water to climb over the damp course.
Rising dampness can be detected with a moisture meter. However, a positive reading does not automatically mean that rising damp is present. Condensation or penetrating dampness can cause similar readings. Sever rising dampness very often leaves a “tide mark” up to a metre above floor level. Dampness very often results in timber decay and dry rot.
Penetrating damp is caused because of poor property maintenance. Items such as defective plumbing and blocked gutters which can cause overflows and these combined with a number of environmental factors can cause damp to penetrate through a structure. Once again, dampness can cause timber decay and dry rot.
Condensation damp is caused when there is inadequate air flow and ventilation within a property. The walls become damp which then causes damage to plaster surface as well as black mould. Unfortunately there will be a musty smell when this type of damp present and this is extremely unpleasant.
