Why Hiring a Licensed Plumbing Contractor Matters in Cambridge, MA
When hiring a plumbing contractor in Cambridge, licensing is your first line of protection. Massachusetts (MA) requires plumbing contractors to hold a valid state license before performing work. This means the contractor has met minimum training, experience, and insurance requirements set by the state. In the Cambridge area, always ask for the license number upfront — licensed pros carry liability insurance that covers property damage and injuries on the job, they must follow current building codes, and you have legal recourse through the Massachusetts licensing board if work is substandard.
Ask for the plumber’s license number and whether they hold a Journeyman or Master designation. Master plumbers can pull permits independently and supervise other plumbers, which means they have more experience and accountability.
