A Derry couple say they face a repair bill of over £100,000 after their family home was one of the first confirmed cases of Mica in Northern Ireland.
Danny and Kate Rafferty built their home on Beragh Hill Road in the city back in 2006 but six years later they noticed what they initially believed were settlement cracks.
When more spider cracks emerged on the outer walls and chimney of the house after it was repeatedly painted, tests carried out earlier this year have since confirmed the presence of high levels of Mica.
