Sizing to your household
We size the new tank to how many people live there and how you use hot water, not just to the label on the old one.
Water Heater Replacement · Mount Vernon, VA
Quick answer
LeMaster Plumber replaces water heaters throughout Mount Vernon, including Wellington, Riverside, and Mount Vernon Estates along the Route 1 corridor. In post-war homes, the old cold-water shutoff above the tank is often seized or dripping. We replace that valve and the old connectors along with the heater, so the new unit starts on fresh fittings. Call (703) 832-9090 whenever you’re ready to set it up.
Mount Vernon’s post-war and mid-century houses put the water heater in a basement, a utility room, or a closet off a hall, sometimes in a space never meant for today’s tank sizes. A gas heater in a small closet needs enough combustion air, so we check the door and vent openings, not just the flue. Old galvanized nipples and corroded valves are common at these tanks, and we swap them rather than reuse them. Newer homes closer to the river usually have simpler access and more room. Fairfax County requires a permit for the replacement, and we pull it and handle the inspection.

Gas and electric tank water heaters installed with new connections, shutoffs and a fresh temperature-and-pressure relief valve.
On gas units we check the flue and draft so exhaust leaves the house. We fit expansion tanks and drain pans where the system or location calls for them.

Every job is backed by proper training, the right permits, and a workmanship guarantee.

Yes. We drain it, carry it out, and take it with us for disposal, so it doesn’t end up at your curb.
It depends on the room’s size and air supply. A gas heater needs enough combustion air to burn safely, so we check the closet and may suggest a louvered door or another fix.
