  • No hot water at all
  • Not enough hot water
  • Water that is too hot or fluctuating
  • Rusty or discolored water

Tank Water Heater Repair and Replacement

Most South Shore homes still rely on a traditional 40 or 50 gallon tank water heater. When yours fails, we can usually replace it the same day with a high quality unit from Bradford White, Rheem, or A.O. Smith. Every tank water heater installation includes:

  • Proper sizing for your household demand
  • Code compliant venting and gas line work
  • New shutoff valve and expansion tank
  • Pan, pipe, and emergency shutoff inspection
  • Haul away and disposal of your old unit

Repair vs. Replacement When to Consider a New Water Heater

If your water heater is 8 to 12 years old or older, it may be approaching the end of its useful life, especially if you are noticing rusty water, leaks at the base, or rumbling sounds during recovery. In some cases a repair still makes sense. In other cases replacement is the smarter long term decision. We look at the full picture, including age, fuel type, anode condition, repair history, energy efficiency, and household demand. When repair costs start to climb past 30 to 40 percent of the price of a new unit, when leaks appear at the tank itself, or when the heater can no longer keep up with your household demand, replacement becomes the more reliable move. We install high efficiency tank, tankless, and hybrid heat pump water heaters from trusted manufacturers and offer clear Good, Better, Best options so you can choose what works for your home and budget. We also handle Mass Save rebate paperwork in house when you upgrade to qualifying high efficiency equipment.
