Water Heater Repair in Katy, TX
Your water heater worked fine yesterday. Most failures are a single component — we diagnose on-site and fix it in one visit, not two.
Repair first — that's the policy
We're not in the business of selling you a new water heater when a $150 part fixes the problem. Every repair starts with a proper diagnosis, and our plumbers carry the most common parts on the truck, so most repairs are completed in a single visit.
Gas and electric units fail differently, and repairing them requires different expertise. Gas work — pilot assemblies, thermocouples, gas control valves, burners, venting — requires a licensed plumber who can verify safe combustion; carbon monoxide from an improperly repaired gas water heater is a serious hazard. Electric work means heating elements, thermostats, high-limit resets and wiring. Our plumbers are trained on both and carry parts for the most common Bradford White, Rheem, A.O. Smith and State models.
When replacement is the honest answer
There are clear signs a repair no longer makes financial sense: the tank is leaking from the bottom (internal corrosion is not repairable), the unit is over 10–12 years old and the repair costs more than half of replacement, you're on your second or third repair call this year, or energy bills have climbed steadily as the unit loses efficiency.
If replacement is the better option, we'll walk you through the choices — traditional tank, tankless, or hybrid heat pump — with transparent pricing and no pressure. We can often install the new unit the same day.
What we handle
Water Heater Repair work we handle every week
No Hot Water
Gas: usually a failed thermocouple, pilot issue, or gas control valve. Electric: a burned-out heating element or tripped reset. We test and replace the failed component on-site.
Leaks & Drips
A T&P relief valve leak means excess pressure or a failed valve — repairable. A tank-bottom leak means internal corrosion, and we'll tell you straight that it needs replacement.
Rusty or Discolored Water
Hot-side discoloration usually means the anode rod has corroded through. Replacing this sacrificial part early adds years to the tank's life.
Popping & Rumbling Noises
Hardened sediment traps water under it; when the burner fires, that water boils and bangs. A full tank flush clears the sediment and restores quiet operation.
Inconsistent Temperature
A failing dip tube mixes cold water into the hot supply. We replace dip tubes and recalibrate thermostats.
Pilot Light Won't Stay Lit
Almost always a failing thermocouple — the safety device that tells the gas valve the pilot is lit. We replace them on all major gas brands.
Triage
What your water heater is telling you
Each symptom points at a specific component. Catching it early usually means a simple repair instead of an emergency replacement.

Before we arrive
Maintenance that prevents the next repair
These steps can limit the damage while our truck is on the way. If you are unsure at any point, stay on the line with us — we will walk you through it.
281-601-1513Flush the tank annually
Draining the sediment before it hardens prevents the rumbling, popping and efficiency loss that lead to early failure.
Inspect the anode rod every 3–5 years
A $30–50 sacrificial part that protects a $1,000+ tank from corrosion. When it's gone, the tank corrodes instead.
Test the T&P valve yearly
Lift the lever once a year to verify it opens and closes. A stuck relief valve is a safety concern, not just a maintenance item.
Set the thermostat to 120°F
Hot enough for comfort, low enough to prevent scalding and reduce energy use.

Don't see your question? Ask a real person — we answer the phone 24 hours a day, every day of the year.
281-601-1513Can you repair my water heater the same day?
Usually, yes. Our trucks carry the most common repair parts — thermocouples, heating elements, thermostats, dip tubes — so most repairs are diagnosed and completed in a single visit. We're also available 24/7 for emergency failures.
Should I repair or replace my water heater?
We always try repair first. Replacement makes more sense when the tank leaks from the bottom (not repairable), the unit is over 10–12 years old and repair costs exceed 50% of replacement, or you're making repeat repair calls in the same year. We'll give you the honest math either way.
Why is my hot water rusty but my cold water clear?
That points to the anode rod inside the tank — a sacrificial part designed to attract corrosion away from the tank walls. Once it corrodes through, the tank itself starts to rust. Replacing the rod every 3–5 years is one of the best ways to extend your water heater's life.
What brands do you service?
All major brands. Our plumbers carry parts for the most common gas and electric models from Bradford White, Rheem, A.O. Smith and State.
Why does my water heater rumble and pop?
Sediment settles at the bottom of the tank and hardens into a layer that traps water underneath. When the burner fires, that trapped water boils and bangs against the sediment. A full tank flush clears it and restores quiet operation.
