It often occurs where there is no damp-proof course (DPC) or where the DPC has been damaged or bridged. Older houses were built without damp-proof courses or with a barrier material that is liable to failure.

The result of rising damp on the inner wall is visible as a darker patch on the plaster lining of the inner wall, usually starting at floor level on the ground floor and rising up from there, hence the term. In extreme cases, salt leached out of the wall forms crystals on the surface of the plaster as the water evaporates. Needless to say, the appearance of rising damp.

Photo of Penetrating Dampness Penetrating dampness is defined as the entry of water into the masonry and external fabric of a building. Symptoms will usually only occur during wet weather. A watermark might appear, and grow if the water continues to enter. If not fixed, plaster may start to perish.

Penetrating damp can sometimes be caused by gutter or roof problems which have allowed rainwater to spill onto and saturate areas of wall. Penetrating damp is most frequent in older homes, which have solid walls. A new build property with cavity walls offers more protection and is unlikely to suffer from this type of defect, unless there cavities have been blocked. Penetrating damp can be tricky to pin-point, and often may require expert help. Installing cavity insulation to exposed walls is becoming a more common problem.

Photo of Condensation Condensation is an increasing problem in houses today. Asal shodieva biografiya semjya. Years ago when houses had open coal fires and ratty windows air could be replaced more often. Fitting plastic windows and doors, draught proofing everything that opens, in the constant endeavour to reduce fuel consumption is sealing in moisture. We charge a small fee to investigate the cause of condensation. In most cases advice from our surveyors can help resolve the problem. Manufacturers Guarantee Reassurance.
