Hot water back today, not next week.

Tank and tankless water heater repair, replacement and installation across the Houston metro.

What we cover

Tank, tankless, gas, electric — and the install behind them.

Tank water heaters

Repair, swap, and full upgrades for 30 / 40 / 50 / 75 gallon units.

Tankless installation

Rinnai, Navien, Rheem — gas and electric tankless installs done to code.

Anode rod & flush service

Annual maintenance to extend the life of an existing tank by 3–5 years.

Diagnosis-first repair

Element, thermostat, dip-tube, T&P, gas valve — the actual fix, not a sales pitch for a new unit.

Repair vs. replace

The 8–10 year mark is usually the decision point. Under that age, a leaky T&P, bad element, or failed thermostat is almost always cheaper to repair. Past 10 years on a tank unit you're typically money-ahead replacing — both the unit and the bills.

We'll give you a flat-rate quote for the repair AND for the replacement on the same visit, with the trade-offs written out, so you can make a real call instead of guessing.

  • Tank installs done same-day in most cases
  • Tankless installs typically 1 day
  • Code-compliant venting and gas hookups
  • Old unit haul-off included

Common questions

Most 50-gallon gas tank replacements land between $1,800 – $2,600 installed. Tankless installs run $4,500 – $6,500 depending on gas-line and venting work.

Tankless wins on long-term operating cost and "endless hot water," but the install is more expensive and may need gas-line upgrades. Tank is simpler, cheaper to install, replaces every 10–12 years.

Yes — annual flush + anode-rod check is the single best thing you can do for a tank unit. We bundle it with our service plan.

No hot water? Let's fix that.

We can usually have a tech at the house the same day.
