Water Heater Repair & Replacement

Gas and electric, all makes and models, with same-day replacement available.

What It Is

Your water heater runs every day, and sediment, worn parts and age eventually catch up with it. We repair what can be repaired and replace units that have reached the end of their life.

Signs You Need It

  • Hot water runs out faster than it used to
  • Rusty or discolored hot water
  • Rumbling or popping from the tank
  • Water around the base of the unit

What To Expect

We check the unit, find the cause and tell you whether a repair or a replacement makes more sense for its age and condition. If you're replacing it, we install the new unit, connect it to code, and haul the old one away.

Residential Services

What We Handle

  • Adjustable wrench and pipe wrench side by side

    Tank Water Heater Repair

    Many problems come down to one worn part, like a thermostat, element, igniter or valve. We test the unit, replace the part that failed, and check that it's heating safely again.


    What's included

    • Full diagnostic of the unit
    • Thermostat, element and igniter replacement
    • Pressure relief valve check
    • Leak check on all connections

    Common signs you need this

    • Lukewarm water only
    • Pilot light that won't stay lit
    • Tripped breaker on an electric unit
  • Supply pipes and fittings mounted on a white wall

    Tank Replacement

    When a tank is leaking or worn out, replacement is the safe fix. We size the new unit to your household, install it to code and take the old one with us.


    What's included

    • Sizing help for your household
    • Removal and haul-away of the old unit
    • New supply, venting and valve connections
    • Startup and temperature check

    Common signs you need this

    • Water leaking from the tank itself
    • Rust on the tank or in the water
    • A unit that needs repeated repairs
  • Person rinsing off under a running shower

    Same-Day Replacement

    Going without hot water is hard on any household. Same-day replacement is available, so in many cases you can have hot water back the same day you call.


    What's included

    • Prompt scheduling when you call
    • Replacement unit sized to your home
    • Full installation and code-compliant connections
    • Old unit removed

    Common signs you need this

    • No hot water at all
    • A tank that has started leaking
  • Close-up of a blue gas flame on a burner

    Gas & Electric Units

    We work on both natural gas and electric water heaters, all makes and models. Each has its own parts and safety checks, and we know both well.


    What's included

    • Gas burner, pilot and venting checks
    • Electric element and thermostat testing
    • Gas line connection and leak test
    • Advice on switching fuel types

    Common signs you need this

    • Yellow or flickering burner flame
    • One element failing on an electric unit
    • Hot water that takes a long time to recover
  • Water running down into a sink basin

    Annual Flush & Maintenance

    Midlands water leaves sediment in the bottom of the tank, which makes the heater work harder and wear out sooner. A yearly flush and check helps the unit last.


    What's included

    • Draining and flushing sediment
    • Testing the pressure relief valve
    • Inspecting the anode rod
    • Checking connections and venting

    Common signs you need this

    • Rumbling or popping while the unit heats
    • Cloudy or gritty hot water
    • No service in the past year
