-health risks: unseen mould growth behind wall linings and external cladding can be a health risk to the occupants, particularly the young or elderly, or those with asthma.
-visual deterioration: deflection or staining of plasterboard linings as a result of moisture trapped behind the linings can cause ugly stains and swelling.
-energy efficiency: a reduction in the building’s energy efficiency can occur due to moisture in the insulation, which can result in loss of thermal performance.
-structural decay: moisture trapped within the structure can result in long term corrosion of metal structures, timber rot, loosening of nails as timber swells, and cladding rot or swelling which can result in costly rectification work.
