Got desperate and used the first available plasterer with a good reputation. He's done my ceilings in my hall stairs and landing. Done my very small bathroom walls and ceiling. Patched up lots in the hall stairs and landing which needed doing. Also some a wall about 2m wide. He's charged me £500. Does this seem reasonable? I need more doing in a few months so not sure if he's expensive and whether to have him back. His work seems ok.
