Water Heater Repair & Installation in Austin
If your water heater died young, blame the Colorado River. Austin's water runs hard, sediment builds fast, and most tanks here give up at 8–10 years instead of the textbook 12–15. We repair what's fixable, flush what maintainable, and install replacements that are actually spec'd for Central Texas water.
Signs Your Water Heater Is Failing
- Rumbling or popping from the tank — sediment layer hardening on the bottom; the heater is working against its own scale.
- Rusty or brown hot water — a spent anode rod letting the tank corrode. Fixable if caught early; fatal if ignored.
- Hot water runs out twice as fast as it used to — sediment displacement or a failing lower element.
- Moisture or pooling at the base — tank seam failure. This one can't wait; a 50-gallon tank drains fast.
- Unit is 8+ years old (check the sticker on the side) — in Austin that's end-of-life for an unmaintained tank.
Repair or Replace? Our Honest Rule
If the tank itself is sound, we repair: elements, thermostats, valves, anode rods, and gas control assemblies are all fixable for a fraction of replacement cost. If the tank is corroded, leaking from the seam, or older than 10 years, we show you the math and let you decide. Our diagnostic visit ($89, credited to the work) includes a hardness test so you know exactly what your heater has been drinking.

Why Hard Water Kills Austin Heaters — and What We Do Differently
Every replacement we install gets: a sediment-screened shutoff, an accessible drain for future flushes, an anode rod inspection schedule matched to your measured hardness, and (if you want it) a thermal expansion tank sized to City of Austin code requirements. Tankless installs include a descaling valve and a maintenance reminder — skip descaling on a tankless here and you'll void the warranty within two years.
