Rising damp begins at ground level as moisture moves upwards through a wall. Common signs include low-level tide marks, salt deposits, damaged plaster and deteriorating skirting boards.

Condensation occurs when moisture in the air settles on a cold surface. It is commonly found around windows, external walls, bathrooms and other areas with limited ventilation. It may cause water droplets, black mould and surface staining.

Because the symptoms can overlap, an inspection is the safest way to establish the cause.
