Start with licensing and insurance – never hire an unlicensed plumber as it can lead to poor work, code violations, and liability issues. Check that they’re properly licensed with Massachusetts and carry both liability insurance and workers compensation.
Look for contractors who provide upfront pricing and don’t pressure you into unnecessary services. Good plumbers will explain what they found, why it needs fixing, and give you options. They should also stand behind their work with warranties.
Local experience matters too. Plumbers familiar with Bellingham’s mix of older and newer homes understand common issues like frozen pipes, aging cast iron systems, and local code requirements. Check reviews and ask for references from recent local jobs.
