Water Heater Repair & Replacement in Rockwall, TX

A failed water heater disrupts your entire household — no hot water for showers, dishes, or laundry — and a leaking water heater left unattended can cause significant floor and foundation damage. Larry's Plumbing provides same-day water heater service across Rockwall and North Texas, and we carry tank water heaters in the most common sizes on our trucks to minimize wait time.

The most common water heater calls we receive: no hot water or suddenly cold water mid-shower (failed heating element or thermostat), rust-colored or metallic-tasting hot water (anode rod failure or tank corrosion), water pooling under the unit (pressure relief valve discharge or tank leak), rumbling or popping sounds (sediment buildup on the bottom of the tank), and reduced hot water capacity in a unit that used to keep up fine.

Not every water heater problem requires replacement. Heating elements, thermostats, pressure relief valves, and anode rods are all serviceable parts that can extend the life of a functioning tank. We diagnose first, tell you what's wrong, and give you an honest assessment of whether repair or replacement is the better investment — including the math. A $250 repair on a 6-year-old tank is almost always the right call. The same repair on a 14-year-old tank with visible corrosion is usually a waste of money.

For tankless water heaters, the most common service need is descaling — flushing mineral buildup from the heat exchanger. North Texas has hard water, and without annual maintenance, scale accumulates and reduces efficiency by 20–30% while shortening the unit's lifespan. We service tankless units from Rinnai, Navien, Noritz, Rheem, and Bradford White.

Every installation includes proper venting (sized for the BTU rating), code-compliant gas or electrical connections, a new drain pan, an expansion tank where code requires, and a pressure and temperature safety valve test. We pull city permits where required and schedule inspections. The price you're quoted includes everything — no add-ons at the job site.
