The work

Repair it, replace it, or size it right.

We diagnose before we recommend — and give you real numbers for repair versus replacement, not a sales pitch.

01 Repair & troubleshooting No hot water, not enough, pilot and element failures, leaks at fittings and valves — diagnosed and fixed.
02 Tank replacement Like-for-like swaps or upsizing — hauled off, brought to code, and set with pan, expansion tank, and shutoffs done right.
03 Tankless installation Endless hot water and less floor space — sized, vented, and gas-supplied correctly, which is where tankless jobs go wrong.
04 Maintenance & flush Sediment flush, anode check, T&P valve test — the cheap visit that adds years to the expensive appliance.
05 Scale protection Hard water is what kills heaters here. Pair a new unit with a softener and it lasts. Softener packages →
02 · The honest call

Repair or replace?

The wrong answer costs you either a needless new unit or a repair bill on a heater that's about to fail anyway. We diagnose first, then give you both numbers and a straight recommendation — the same one we'd make in our own house.

Book a diagnosis→
Usually repair

Under 8–10 years old · Failed element, thermostat, or pilot · Leak at a fitting or valve · Unit sized right for the home

Usually replace

Past 10–12 years · Leaking from the tank itself · Rust in the hot water · Heavy scale, rumbling, repeat repairs

Either way

You get the diagnosis, both numbers, and the recommendation — then you decide. No pressure, no scare quotes about "catastrophic failure."

Questions

Water heaters, answered.

Heater down right now? Call — a standard swap is usually same or next day.

(512) 755-7318→
+Should I repair or replace?

Under 8–10 years with a fixable fault — usually repair. Past 10 years, leaking from the tank itself, or scaled beyond recovery — replacement. We diagnose first and give you numbers for both.

+Tank or tankless?

Tankless gives endless hot water and reclaims floor space, but needs proper sizing, venting, and gas supply. Tanks cost less up front. We'll walk both against your home and usage before recommending either.

+How fast can you replace a failed heater?

A standard tank swap is typically same or next day, depending on schedule and unit availability. Call (512) 755-7318 and we'll give you a real window.

+Does hard water kill water heaters?

Yes — Central Texas hard water scales up tanks and elements, cutting efficiency and lifespan. Pairing a new heater with a whole-house softener is the best protection you can buy it.
