Q. How do I know if I have rising damp in my property?
A. More than 90% of all damp problems in modern properties is caused by the practice of fitting plaster on external walls all the way down to ground level without leaving a gap in the plaster at the height of the damp proof course (dpc). In some homes, developers fail to fit dpc sheeting beneath floor slabs and only fit it in the brickwork, believing the concrete slab to be impermeable and non-porous. Regrettably this is not the case and damp will rise in the slab and first manifest itself as damp patches in carpets or damaged wooden flooring or damaged plaster and skirtings on internal walls. This is a serious condition and one which requires the services of a competent and professional dampproofer to solve. Homes built in the 1960’s, and older, were often fitted with a malthoid dpc which over time becomes brittle and allows moisture ingress. Many old homes also had suspended wooden floors which are prone to damp especially if airbricks and voids beneath the floors are filled in. Both situations require a carefully thought out solution and the services of a dampproofing specialist should be sought. The presence of damp on internal walls is often the first indication of rising damp in older properties or those without a dpc beneath a floor slab. But this could also be due to a failure to adequately waterproof a shower or may even be due to a leaking pipe. If in doubt, always seek professional advice.
