I live in the Home Counties and in a two-storey mid-terrace house. The house next door (on left) is two foot lower than mine so the wall at the top of my house on the side is higher than that house so exposed and sadly the brickwork has weathered, pointing gone or flashing gone ... anyway damp is getting into my attic. A roofer came today but like the one before did not get on the roof and told me that I'd need scaffolding erected for him to examine the damage, seek the problem and then deal with it. He quoted me £250 to erect scaffolding on the front elevation and £300 if it needed more at the rear (and then presumably link the two with a walkway over the house?). Is this a decent price?
