Before you hire
Ask which permits the job needs and who will get them; your municipal building department can tell you before work starts.
Get written quotes from at least three contractors for the same work, and check references from recent clients.
Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.
