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 · McLean, VA
Quick answer
In Langley, Chesterbrook, Salona Village and across McLean, LeMaster Plumber replaces water heaters. Large homes and custom builds here often have more than one heater, a recirculation pump, or a high-capacity or power-vented unit. We replace the whole setup together, so hot water stays even across every bathroom. Call (703) 832-9090 and we’ll look at what your home has now.
McLean’s large homes and estates often put the water heaters in a basement mechanical room, sometimes two or more side by side. Custom builds may use power-vent tanks, high-capacity units, or tankless systems with a recirculation loop. When one fails, the others are often close to the same age, and replacing them together keeps things balanced. We check the recirculation pump and its timer, the gas supply for the total load, and the vent path for each unit. If the mechanical room sits under finished space, a drain pan and leak sensor are worth adding.

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.
Water heater replacement is permitted work. We pull the permit and handle the inspection so you do not have to.
We drain and remove the old tank and take it with us. You are left with a working heater and a clean space.
If you keep running out of hot water or need the floor space, we will walk through whether a tankless unit fits your home.
We check its age, the leak or failure, the fuel type, the venting and the space, and confirm replacement is the right call.
You get the unit, the scope and the price before anything starts. You approve it first.
We shut off and drain the old tank, remove it, and install the new one with new connections, valves and venting to code.
