Common Questions
How much does water heater replacement cost?
It depends on size, fuel and tank vs. tankless. Call for current pricing, and take $100 off installation with code HEATER100.
Should I go tankless?
Tankless saves space and won’t run out of hot water. It costs more upfront. We’ll quote both so you can compare.
Can I replace my 40 gallon gas water heater with the same size?
Usually yes. We’ll confirm the size fits your household’s hot water use.
Can I replace a water heater myself?
In Massachusetts, gas water heater replacement requires a licensed plumber and a permit.
