I don't live in the UK, but watching BBC, it seems that you have specialists for almost every conceivable job out there. Here in SA, everyone is a jack-of-all-trades - especially in the building industry. I bought a house that was built in 1962 and there is a mother of a crack running from the ceiling to the floor in a part that was added on later. I have had 6 different contractors out, and they all seem to have their own theory of how to fix the crack. Is there someone out there who can PLEASE give me professional advice?
