I worked as a "labourer" on work experience a few years ago, with a company run by my neighbour. I dont think it exists any more. They were contracted directly by insurance companies to repair properties. Got a lot of work, right from Leeds to Hull. Employed about 15 tradesmen. A couple of bricklayers, couple of plasterers, artexer, spark, plumber, joiners, jacks-of-all-trades etc. The company seemed to get on ok with the insurers, moneys paid on time etc. Certain jobs, we would collect the insurance excess from the customer on the insurance co's request.
Most jobs were water damage, and when i was working with their surveyor, we would always over-do the work, so the house was restored to its original quality, if not better. So water down one wall and ceiling in a kitchen, couple of kitchen units damaged - quote for replacing ceiling - messy job, so also replace all kicthen unit doors and worktops (chances of getting matches unlikely). Redecorate entire room. Customer happy.
