Rising damp is caused by ground water moving up through a wall or floor. It’s natural for walls and floors to allow a little water in, but it’s usually stopped from causing damage by a barrier called a damp-proof course or damp-proof membrane. A damp-proof course is a waterproof horizontal strip, usually made of plastic or bitumen felt, built into the wall at a height of at least 15cm above ground level. When a property has rising damp issues there are two reason why this is occurring, one can be there no was no DPC original installed or two the original DPC has become faulty
Condensation is the most common kind of damp. It is caused by moist warm air condensing on cool walls, particularly in rooms that naturally generate a lot of air moisture, such as kitchens and bathrooms. It’s mainly, but not always, a winter problem, as walls tend to be colder than the air inside. Condensation can be exacerbated by central heating that gets very warm and then cools down again, as this creates warm, damp air that can then condense, causing condensation.
Wet and Dry Rot
Wet rot & dry rot is a type of fungal decay of timber and can occur when timbers are in contact with damp situations and are not ventilated properly such as sub floors. Dampness can come from defective guttering, defective plumbing, rising damp or high ground levels and many more. If there is dampness then wood rotting fungi can develop and cause substantial damage.
A basement conversion is the process of changing this space into an inhabitable room. There are varying degrees of basement conversion from a basic conversion to one that involves excavation and expansion in order to create sufficient height to be habitable.
Penetrating damp, otherwise known as lateral damp, is the end result of water successfully penetrating from the outside of a building and into your property. Unlike rising damp, penetrating damp can happen at any level within the property including roofs, ceilings and walls
