A dead water heater never picks a good day. Whether it's a pilot that won't stay lit, a leaking tank in the garage, or lukewarm showers that keep getting shorter, we diagnose it on the spot and quote a flat price before touching a tool.

We stock the parts that fail most in San Antonio homes (thermocouples, heating elements, gas valves, T&P relief valves), so most repairs finish the same visit. If the tank itself is gone, we'll give you an honest replace-vs-repair comparison with real numbers, including code-required upgrades (expansion tank, pan, venting) so there are no surprises on install day.

Hard water in Bexar County is brutal on tanks: sediment shortens tank life and cooks heating elements. If your unit is past 10 years, we'll tell you straight rather than sell you a repair that won't last the summer.

When to call us

  • No hot water, or it runs out in minutes
  • Water pooling under or around the tank
  • Pilot light won't stay lit, or breaker keeps tripping
  • Rumbling, popping, or banging from the tank
  • Rusty or metallic-smelling hot water

Common questions

Repair or replace: how do you decide?
Rule of thumb: if the tank is under 8 years old and the fix is a component (element, thermostat, gas valve), repair wins. If the tank itself leaks or it's past 10 years in our hard water, replacement is the honest answer. We show you both prices and let you choose.
Can you install the same day?
Usually yes. We carry common 40- and 50-gallon units and standard fittings on the truck; most replacements are done within hours of your call.
Do you handle permits?
Yes. Water heater replacements in San Antonio require a permit; we pull it and install to current code, including the expansion tank and pan required on most installs.
