I once did some work with a building company, which specialised in insurance work. They did great jobs. They were referred to the jobs directly by the insurers via fax. I went in a few houses with seemingly small damage to a ceiling, for instance, from a water leak. They would pull down the whole ceiling, coving, and redecorate the whole room, then artex the ceiling too, and replace any of the lower chipboard floor that needed it. They had about 20 tradesmen.
I went in one nearly new house, that had had a water leak on the GF. Work had already started. The whole of the GF chipboard floor was up. If this had been an old house, a few boards would have been replaced locally to the leak, but because this house had a floating chipboard floor on polystyrene, the whole lot had to be replaced. A great waste. Makes me wonder if the new technology in building is really worth it.
Another instance was a pan fire scene, it had only damaged a few cabinets, first thought was to get new cabinets. No longer made. So the whole kitchen had to be replaced, worktops, doors, cabinets to match.
We also came across a couple of jobs where our first words when we set foot outside were "bloody insurance fraud"
