Emergency Water Heater Repair in Katy, TX
A water heater that quits overnight is one of the most common calls our Katy dispatch takes, and it's usually fixable the same day. Whether the unit has stopped heating entirely, started leaking at the base, or is making a rumbling noise that's gotten louder over the past few weeks, a plumber can diagnose the real cause and give you an upfront price before touching anything.
Why This Happens in Katy
Katy's humid Gulf Coast climate and the mineral content in West Houston's water supply both shorten a tank's working life compared to drier, softer-water regions. Older homes near Katy's historic district are more likely to be running a tank that's outlasted its rated lifespan, while newer builds in communities like Cane Island usually have a modern, code-compliant unit that's more likely to need a repair than a full replacement.
Signs You Need Water Heater Repair & Replacement
No Hot Water
Cold showers, or a unit that can't keep up with demand for a household this size.
Rusty or Discolored Water
Often signals internal tank corrosion, especially on a unit over 8 years old.
Popping or Rumbling Noises
Sediment buildup rumbling and popping as the unit heats, common with Katy's water hardness.
Leaking at the Base
Moisture pooling under the tank usually means the tank itself has failed, not a fitting.

How We Diagnose It
A plumber checks the tank's manufacture date first, since age alone rules a lot in or out. From there it's a pressure test to isolate whether a leak is coming from the tank itself or a fitting, a check of the thermostat and heating element on an electric unit, and a check of the gas valve and thermocouple on a gas unit. The anode rod gets inspected too, since a corroded one is often the real reason a tank failed early.

Repair or Replace?
Repair Usually Makes Sense When
- The unit is under 6 years old
- The issue is a single part: element, thermostat, valve
- No visible tank corrosion or leaking
Replacement Usually Makes Sense When
- The tank is leaking at the tank itself, not a fitting
- The unit is 10+ years old
- You want to switch to tankless for more capacity
What Water Heater Repair & Replacement Costs
Repairs typically run $150 to $600. Tank replacement runs $1,200 to $2,600 installed. A tankless conversion runs higher. Exact quote after inspection, before any work begins.
Homeowners insurance sometimes covers water damage from a sudden tank failure, but the tank itself typically isn't covered as routine wear. Check your policy's specifics. Want your real number? Call (281) 626-9205.
Scope, Honestly
We service and replace residential water heaters up to standard household sizes. Large commercial boiler systems are outside what we handle, and a plumber will say so upfront rather than take the job and improvise.
What to Check or Shut Off
If the tank is actively leaking, shut off the cold water supply valve at the top of the unit before calling.
For a gas unit with a strong gas smell, leave the house and call your gas utility before calling us.
Switch off the breaker to an electric unit if it's sparking or the area around it is wet.
Note the tank's age from the label if you can safely see it. It speeds up the phone diagnosis.
