What we handle

  • Tank water heaters: gas and electric, repair and same-day replacement when the schedule allows
  • Tankless water heaters: diagnosis, descaling, repair and new installs
  • Warranty help: we call the manufacturer and get covered parts replaced before suggesting a new unit
  • Your own unit: bought a heater on sale at a store? We’ll pick it up and install it
  • Expansion tanks, relief valves, gas valves, thermostats and elements

Signs your water heater needs attention

  • No hot water, or it runs out much faster than it used to
  • Rumbling or popping from the tank (sediment build-up)
  • Rusty or discolored hot water
  • Water pooling around the base of the tank
  • The pilot light keeps going out on a gas unit

Repair or replace?

Plenty of “dead” water heaters only need a part: a thermocouple, element, thermostat or gas valve. MJ tells you what’s actually wrong and what each option costs. If the tank itself is leaking, it’s replacement time, and you’ll get an honest recommendation on size and brand, plus whether tankless makes sense for your home.

Common questions

How long does a tank water heater last?

Most tank water heaters last around 8 to 12 years, depending on water quality and maintenance. If yours is in that range and leaking from the tank, replacement is usually the better value.

Can you install a water heater I bought myself?

Yes. If you bought a unit on sale, MJ can pick it up and install it, including the venting, gas or electrical connections and code-required parts.

Is tankless worth it?

Tankless units cost more up front but give endless hot water and save space. They suit some homes better than others; MJ will tell you honestly whether it pays off for your household.

How fast can you come out?

Call 667-371-1242. Same-day service is often possible, and you’ll get a straight answer about timing on the phone.
