We moved into a new house, totally new build. The day we moved in these people sent out a engineer? fitter? cowboy? to fit our aerials. Eventually I had to have the builder and NHBC back for we had damp patches appearing in the upper ceilings. It materialise, the chap who had fitted the aerials had drilled holes actually through the roof, under a tile and put the cables through there, so when the wind and rain are in the wrong direction the water is seeping in under the tile and after the 12 inches of roof insulation can`t hold any more. The ceilings have now got damp patches. It`s costing me money to have a qualified fitter to redirect the wires, but I wouldn`t have these cowboys anywhere near my house. Marks out of 10, they don`t even qualify.
