Hi all, Homeowner asking for some advice here. Basically, my house has a bit of a slope and I asked some joiners to give me a quote to fix it. Since it will require extensive work, they wanted to do a survey of the flooring of the house, to look for some joists, etc. I was told that they would have to survey loads of places and it would take them the best part of the day. However, at the end, they only had to survey a couple of areas and took only 1.5 hours to do their thing. No additional materials were required to patch up areas where they had been. I have been sent the invoice which apparently covers for the entire day rate and materials- around £400. Am I right to be think that this is fishy?
