Independent damp surveys in Aberystwyth, Ceredigion.

Aberystwyth contains a varied building stock, including traditional masonry buildings, Victorian and later terraced properties, larger period buildings, converted properties and modern residential development.

Moisture problems within these buildings can have several potential causes. External exposure, roof and chimney defects, rainwater disposal, ground levels, ventilation, internal alterations and the materials used during previous repairs can all influence how moisture enters, accumulates and evaporates from the building fabric.

Rather than diagnosing a property from isolated moisture meter readings, our surveys consider the building as a whole to establish the likely moisture mechanism and appropriate next steps.

Aberystwyth's coastal location means buildings can experience significant exposure to wind-driven rainfall. The condition of external walls, pointing, render, roof coverings, chimneys, window junctions and rainwater goods can therefore be particularly important when investigating internal dampness.

The town also contains a substantial stock of older and period properties. These may incorporate solid masonry walls, traditional mortars, suspended timber floors and construction that predates modern damp-proof courses and cavity wall detailing.

Later alterations can further complicate moisture behaviour. Cement-rich pointing, dense renders and plasters, changes to floor construction, insulation and reduced ventilation can all affect the way an older building manages and releases moisture.

Our approach is therefore based on building pathology rather than assuming that elevated moisture readings automatically indicate rising damp or require chemical damp-proofing treatment.
