About This Market
Boston's plumber market runs hot with 3034 licensed establishments competing across Massachusetts. Demand stays steady year-round but spikes during winter freeze-ups and spring thaw damage. Old housing stock means constant repair work - cast iron replacements, boiler servicing, and code upgrades for renovations. Union presence keeps wages high but also drives up project costs. Emergency calls command premium rates, especially in Back Bay and North End where access is tight.
To work Boston plumbing, you need thick skin for the licensing maze and patience for city permits. The 4-year apprenticeship requirement weeds out casual players - this isn't a weekend warrior trade. Master license opens doors but takes years to earn. Winter emergency work pays best but demands 24/7 availability. Know the local codes cold - Boston inspectors catch everything. Build relationships with general contractors doing gut rehabs, that's where the steady money lives.
