Has no one else had a comeback on a render you have done on a cavity filled house? We have had one and it was put down to the cavity being filled with the lagging type being wet inside. Anyway we are pricing regularly and every other house we come across has had the shite pumped in. Some of the existing renders we see are f**ked . Some of them are done recently and as always they blame whoever rendered it. Most say they have damp inside. I spoke to a guy at eco rend who said it’s a problem.
