We're looking at getting new carpets fitted throughout the first floor in our house. Got in touch with a local family-run shop, which has very good reviews. We discussed the types of carpet, then they visited, measured up, and provided a quote. My issue is that the quote is just one lump sum, without showing the break down for materials (carpet, underlay, grippers) and fitting. When I questioned that, they said it's just how they do things. Is this normal?
