Social housing tenants with damp 'have no idea where to turn'
Damp, mould and condensation has been caused in Welsh social housing by inappropriate cavity wall insulation, a report has found.
More than 280 homes have had insulation removed in Rhondda Cynon Taff alone, while 900 properties require remedial action in Neath Port Talbot.
The problems have been revealed in a draft report for the Welsh government, seen by BBC Wales.
The Welsh government said it could not comment until the report has been finalised.
Pauline Saunders, from Newport, who founded the action group Cavity Insulation Victims Alliance, called it a "huge problem".
