You should always get 3 quotes for larger jobs, so you can compare and understand what you are being charged for. It is almost impossible for someone to check a quote without being given the chance to come and see the work you need doing (and getting the full brief that you have given to the builder).

You can find builders that have been vetted and are local here:
