Before you hire
Have fuel-burning appliances such as a furnace or boiler inspected by a professional at least once a year.
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.
