Our Water Heater Repair Services in Greater Boston & the South Shore

Our technicians assess your tank water heater, explain the problem in plain language, and provide upfront pricing before any work begins.

Pilot Light and Ignition Repair

We diagnose and repair pilot lights that won’t stay lit and other ignition system issues on gas water heaters, restoring a reliable flame and consistent hot water.

Thermostat and Heating Element Repair

We repair and replace faulty thermostats and heating elements on electric water heaters, fixing inconsistent or insufficient hot water at the source.

Sediment Buildup and Flushing

Sediment that settles at the bottom of your tank reduces efficiency and causes rumbling or banging noises. We flush your tank to clear buildup and restore performance.

Leak Repair

We locate and repair leaks around fittings, valves, and connections, and assess whether the tank itself is affected.

Valve and Fitting Repair

We repair and replace worn shut-off valves, temperature and pressure relief valves, and other fittings that can affect your water heater’s safety and performance.

Signs You Need Water Heater Repair

A few warning signs tend to show up before a water heater fails outright:

  • Insufficient hot water: If your water heater isn’t producing enough hot water, or it’s taking longer to heat up, it may need repair.
  • Strange noises: Rumbling or banging sounds often point to sediment buildup or another mechanical issue.
  • Leaks or water damage: Any visible leaks or signs of water damage around the unit should be addressed promptly.
  • Inconsistent water temperature: Fluctuating temperatures can signal a faulty thermostat or heating element.
  • Pilot light problems: A pilot light that won’t stay lit or goes out frequently often points to an ignition system issue.
  • Age: A water heater nearing or past the end of its expected lifespan is more prone to problems and more likely to need repair.

If any of these sound familiar, our technicians can diagnose the issue and walk you through your repair options.

Frequently Asked Questions (FAQs)

Should I Repair or Replace My Water Heater?

It depends on your unit’s age and repair history. If your water heater is under 10 years old and has had only minor issues, a repair is usually the more cost-effective choice. If it’s older than 10 years, needs frequent repairs, or a repair estimate is close to half the cost of a new unit, replacement typically makes more sense.

Do You Repair Gas and Electric Water Heaters?

Yes. We repair both gas and electric tank water heaters. Gas units commonly need pilot light and ignition repairs, while electric units more often need thermostat or heating element repairs, and our technicians are equipped to diagnose and fix either type.

How Much Does Water Heater Repair Cost?

Water heater repair costs depend on the issue, the parts needed, and whether you have a tank or tankless system. We provide an upfront quote after diagnosing the problem, so you know what to expect before any work begins.
