Water Heater Repair in Northeast Texas

No hot water on a Monday morning is usually a part, not a new water heater. Underwood repairs tank and tankless units across Collin, Grayson, Fannin, Hunt, and Lamar counties.

No Hot Water? Call and We'll Get a Tech Out.

If the unit is leaking at the base, shut the supply if you can and call (903) 449-1677. Evenings included.

Our Water Heater Repair Process

Call or request a quote: No hot water, a puddle, a rumble, or a pilot that won’t stay lit.

Find the failed part: Thermostat, element, gas valve, igniter, or a tank that’s actually split.

Explain repair versus replacement: Age, the leak, and the part. You hear both numbers before we order anything.

Repair it in one trip: The parts we replace most ride on the van.

Test hot water: We run a tap until it’s hot, and we check the pan and the fittings for a drip.

Leave the closet dry: The pan and the floor get dried before we leave.

The Underwood Water Heater Standard

Do you repair tankless water heaters too?

Yes. Igniters, sensors, and scale on tankless units, plus the usual tank parts. If the heat exchanger is done, we’ll say replacement is the better money.

Is a puddle always a failed tank?

No. Fittings, the T&P valve, and the pan drain leak too. A split tank leaks from the steel, and that’s when we talk replacement.

Where do you repair water heaters?

Collin, Grayson, Fannin, Hunt, and Lamar counties, including McKinney, Sherman, Denison, Bonham, Greenville, and Paris.

Do you come out in the evening?

Yes. No hot water with kids in the house doesn’t wait. We pick up nights and evenings.

Is a repair covered by the membership?

The Plumber’s Club includes an annual flush and 10% off service calls. Repairs themselves are billed. Ask when you book.

Why Underwood

Why Northeast Texas Calls Underwood for Water Heater Repair.

We Communicate.

We pick up and we tell you when the tech is coming. Cold showers don’t need a vague window.

Stocked Trucks, One Trip.

Elements, thermostats, valves, and igniters are on the van, so a repair usually finishes that visit.

Plumbing and Septic, One Call.

If the ‘no hot water’ is really a gas line, a recirculation pump, or a septic backup into a floor drain, we handle that company-wide.

Seasoned Service Professionals

Nexstar trained techs, state-board licensed, TCEQ registered.

What We Fix

Water Heater Repairs, Start to Finish

No hot water: power, gas, thermostat, and element checked before anyone says 'replace it.'
Leaking fittings: supplies, the dielectric unions, and the T&P valve, distinguished from a split tank.
Rumbling tanks: sediment flushed when the tank is still sound.
Pilot and igniter faults: gas valve and igniter diagnosed, not swapped at random.
Tankless error codes: the code read, the part replaced, the unit fired and checked.
Pan overflows: the drain line cleared so the next drip doesn't soak the closet.

Financing Available

We offer flexible payment options for our services.

Signs It's Time to Call for Water Heater Repair

The hot side runs cold at every tap.
A puddle in the pan, or rust in that water.
Popping or rumbling when the burner kicks on.
The pilot won't stay lit.
A tankless unit flashes a code and won't fire.
Lukewarm water that runs out in one shower.

 Trustindex verifies that the original source of the review is Google. I needed a sewer tank cover replaced due to it being hit by the lawnmower. These guy fixed it in less than 30 minutes.
Chad also suggested putting landscaping stuff around the 4 tanks to prevent this happening again. Totally happy with their service.
