Condensation and Dampness
Condensation is by far the most common cause of dampness in buildings, probably accounting for the majority of damp problems reported. It affects both old and new buildings, and can be a significant problem where the building has been modernised. Although it's the most common cause of damp it's not the only cause you may have rising damp.
Condensation is directly associated with mould growth which is associated with many health problems. It is this that the occupier sees first, and it gives an indication of the potential scale of the problem. The mould is usually found on decorative surfaces, especially wallpapers, where it can cause severe and permanent spoiling. In many cases, the mould and its spores ('seeds') give rise to complaints about health, and cause the "musty" odour frequently associated with a damp house.
The obvious places for condensation to occur are on cold walls and floors, but it can also occur in roof spaces and in sub-floor areas where there is a timber suspended floor; in the latter case, it can lead to rot developing in floor timbers.
Cracks in Walls and Ceilings
Over time, many building foundations sink due to the soil moisture or the terrain type that the building has been constructed on. The more serious causes are usually caused by improper construction and/or settling foundations, which requires the expertise of a structural engineer to evaluate the issue. Other causes for uneven floors include cracked floor joists, termite damage, and inadequate sub-floor supports. There also could be other environmental reasons, such as floods or heavy rainfall.
Common problems that you notice are sticking doors or windows, Cracks in brickwork or concrete. diagonal cracks in walls or unevan or sloping floors.
Rising Damp
This can indicate a problem with the original dampcourse.
Rising damp (or salt damp, as it is known in many parts of the world) is not the most common form of dampness encountered in buildings; this is left to condensation.
However a high proportion of older buildings are affected by rising damp to some degree or another. In general, walls prior to the 1970s did not have damp courses or inferior ones, which allowed the damp to rise in capillary action. In many cases of rising damp in more modern walls the causes are often traced back to bridging/ breaching of the D.P.C. (Damp Proof Course).
Termites (Also known as "White Ants")
To discourage termites and improve inspection access.
Always fix leaking water pipes and drains.
Always have regular inspections for termites.
Improve sub-floor ventilation, drainage and access.
