Penetrating Damp in Manchester

Penetrating damp is classed as any water that finds its way inside from the outside. It occurs at all levels of the building, damaged pointing, faulty rain water goods, such as gutters, downpipes, leaking valleys or a combination of these can all cause problems within a building.

In garden level rooms or basements, if the soil or path is higher than the damp proof course, if an incorrect plastering specification is used or if the exterior walls become porous and are allowing rain water through, these are all sources of penetrating damp.

The problem of penetrating damp in Manchester, if not addressed, can also cause secondary damage to a building. The unwanted moisture enables the growth of various fungi in wood causing rot and leaving it susceptible to insect attack. It can also damage plaster and decoration causing it to deteriorate and loosen. It requires a trained and qualified specialist surveyor to make an accurate diagnosis of the underlying cause of damp penetration and recommend the correct course of action.
