New install
Water Heater Replacement
Tank and tankless water heater installation, replacement, and repair.
Sizing the unit to the house, not to the box on the shelf
Every property uses hot water differently, so the first job on a replacement is a short interview. How many people shower in the morning, whether the dishwasher and washing machine run at the same time, where the heater sits relative to the farthest bathroom, and whether the house is gas or electric all decide what belongs on the wall. A tank that is too small is the most common reason a new heater runs out of hot water in the first year, and an oversized one just wastes energy keeping water hot that nobody uses.
For a Greenville family that means we compare capacity, efficiency and installation requirements with you before work begins, tank against tankless, so the decision is yours and you are comfortable with it. A tankless unit changes the gas line, venting and water supply demands; a tank swap mostly keeps what is already there. We lay that out at the free on-the-spot estimate and put nothing on the schedule until you approve it.
The same approach covers commercial properties around the Upstate. A shop or an office has its own peak demand, and we recommend equipment from how the building actually operates, not from a one-size-fits-all catalog page.

A Saturday emergency, swapped the same night
Heaters rarely fail at a convenient hour. A tank that starts leaking on a weekend or goes cold the night before guests arrive is an emergency no-hot-water call, and it goes to the front of the board. David D., on Angi in 2011, described the pattern: a water heater emergency on a Saturday, Steve came out the same day, charged no estimate fee, and had a new heater installed that night.
Same-day replacement works when the diagnosis is fast and the sizing decision is made on the spot. We confirm the old unit is the problem, not a tripped breaker, a dead element or a thermostat, then drain it, disconnect it from the water, gas or power, and set the new heater on a drain pan with fresh shutoffs and an expansion tank where the system calls for one.
If the water is already moving, shut the cold supply to the heater, switch the unit off, and call the 24/7 line at (864) 436-3006. We dispatch the nearest licensed plumber as soon as a truck is free, and we are honest on the phone about timing.
What the install includes and what stands behind it
A replacement is more than swapping a tank. A wrong size, a skipped expansion tank or poor venting is how new heaters fail early. We handle the venting, drain pan, expansion tank and shutoff valves as part of the install and leave you with the manufacturer paperwork, so you know the model, the capacity and the warranty terms on what is now on your wall.
Two warranties apply and we keep them straight. Manufacturer warranties cover the heater and its parts. Our one-year labor warranty covers qualifying work from All About Plumbing, and a callback is something we would rather do than leave a homeowner living with a leak we already touched.
Before you commit to a replacement, ask about the free water heater flush and 65-point whole-home inspection on the Water Heater Service page. If the unit still has life in it, we will say so. If it does not, you will know exactly where the rest of your plumbing stands before the new heater goes in.
