Check them out

Do your research. A building firm could be in your home for several weeks, so it is important that you trust them. Get references, which a good professional will be happy to provide, and check them out. If the builder claims to be a member of a trade association such as the FMB, check what that membership means and find out if they really are members. Scrutinise their credentials before going ahead. Don’t just rely on Yellow Pages, search for a vetted local builder at the FMB’s website
