Dampness in buildings can amongst other things lead to serious fungal attack, ruin internal decoration and can also cause serious health issues. It can come in the form of penetrating damp where water enters the property from an external defect, rising damp where the moisture rises from the ground through the pore structure of the masonry affecting the inner plasterwork, and atmospheric dampness caused by the effects of condensation. It is important that the property is kept wind and watertight to help prevent this. Dampness, no matter which kind, will require guaranteed remedial works internally once the external defects have been rectified
