  • Above Ground Damp Control

  • Rising Damp, as the term suggests, is moisture rising up a wall from the ground. Nearly all ground water contains small quantities of ground water salts and if the rising damp is only minor this moisture can often evaporate and go undetected but unfortunately the ground water salts are left behind within the wall and plasterwork.

    Over a length of time this damp can start to spoil decorative finishes such as plasterwork, wallpapers and paints and the deposited salts can start to cause an unsightly crystallisation on the surface of the wall. Associated joinery such as skirting boards, floor joists, etc, may start to rot and then treatment of the wall will probably be required.

  • Penetrating Damp is water that has managed to enter the building from the outside, possibly through a roofing defect, the penetration of solid external walls that do not have a cavity, if cavity walls are present these might possibly be blocked with debris, a blocked or inadequate guttering system, possibly penetration from a neighbouring property through a dividing party wall, etc. etc.

    With each problem one of the most crucial aspects in its remedy is determining the type of cause so the correct remedial measures can be recommended. The diagnoses must be accurate and correct before a remedy can be determined. Once a cause has been accurately determined then a program of cost effective maintenance or repair can be put into place.

  • Condensation dampness affects many, if not most homes to some degree and is, in broad terms, the result of excess moisture within the air. This if coupled with inadequate heating and ventilation can often result in surface moisture. Then if other circumstances within the property are right this can then lead to the forming of unpleasant moulds and fungal growths.

    This form of damp may be caused by a fault within the building such as a plumbing leak, rising or penetrating damp or occupational activities such as drying clothes, cooking, bathing, etc, which, without adequate heating and ventilation, can lead to high levels of atmospheric moisture. This atmospheric moisture, when conditions allow can then condensation on cold surfaces and allow the forming of surface moisture and resulting moulds.
