Damp and damp proofing is by far, the most frequent problem encountered in the home. Each year, the average home in the UK copes with around 15,000 gallons of rain water, so it is no surprise that damp proofing can become a big problem for many. Although most damp problems are much less serious than they actually look, whatever the cause, damp can be very bad for our health.
Dry rot is the most serious type of timber decay in buildings because it can cause rot at a lower moisture content than wet rot fungi and it has the ability to grow through damp masonry and brickwork, and behind plaster. It can therefore spread rapidly through a building, making treatment more complicated than with other types of rot.
Wet rot is a general term used to describe the majority of fungal species responsible for timber decay. All wet rot fungi require higher moisture contents than the dry rot fungus, Serpula lacrymans and are much more common. However, they do not have the same ability to spread through a building so are much easier and less expensive to eradicate.
Materials such as stone and brick are naturally porous and will absorb moisture through capillaries. As long as a damp proof course is intact, it will prevent the walls of the property from doing so. If not, the walls will draw moisture up & this condition is rising damp
Most frequent in older homes that have solid walls, penetrating damp can be tricky to pin-point. Symptoms of penetrating damp include watermarks that may appear on the masonry and grow if the water continues to enter. If not fixed, plaster may start to perish. Moreover, Penetrating damp can sometimes be caused by gutter or roof problems which have allowed rainwater to spill onto and saturate areas of wall.
Still unsure about the type of damp problem you have. Why not request a property repair survey
