Hi I am about to exchange/complete on a New Build with Barratt Homes in Exeter. A few days before I noticed that the skirting boards in two rooms had mould on them. I was told it due to condensation and also its because the house have been kept closed i.e not ventilated properly. I am concern that when I move in the problem with get worse. I am allergic to mould hence my hestitation to exchange, despite Barratt's assurance that they will do everything to make sure that the mould goes. Any thoughts?
