What to expect
Most water heater calls are repair-first. Anode rod failure, thermocouple failure, heating element burn-out, gas valve failure, and sediment buildup all have repair paths in the $200 to $700 range. Replacement makes sense when the tank is leaking from the body (corroded through, can't be fixed), the unit is 10+ years old and has failed once already, or hot water demand has grown beyond the unit's capacity.
Every install includes removal and disposal of the old unit, new shutoff valves on hot and cold supply, expansion tank if your code requires it (TX requires it for closed systems), drain pan and pan drain line for closet or attic installs, code-compliant venting for gas units, permit and inspection if your city requires it, and 1-year warranty on labor plus manufacturer warranty on the unit.
If you're seeing rusty water, popping or banging, a puddle at the base, no hot water, or hot water that runs out fast, call (972) 210-9033. We'll talk through it on the phone first and tell you if it's repair or replace before we drive out. More on the symptoms in our blog post on water heater failure.

What homeowners say
“We had a slab leak and were panicking. Chad walked us through the whole process, explained what he was doing at every step, and his price was fair. He even followed up the next week to make sure everything was holding. This is the only plumber we'll call from now on.”
Jennifer K.
Frisco, TX
“The last plumber we called tried to sell us a whole new system when all we needed was a valve replacement. Chad was honest about what the actual problem was and fixed it for a fraction of what the other company quoted. That's rare.”
Mike R.
Plano, TX
“Chad came out the same day we called. He looked at our water heater, told us exactly what was wrong, gave us a price, and got it done that afternoon. No surprises on the bill. We've used other plumbers in the area and this was by far the best experience.”
