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 · Chantilly, VA
Quick answer
Chantilly is right next to our Centreville base, and LeMaster Plumber replaces water heaters there in neighborhoods like Greenbriar, Poplar Tree, and Franklin Farm. Most homes here date from the 1980s and ’90s, so even a tank that was already replaced once may be coming due again. We check the age on the label and tell you plainly. Call (703) 832-9090, and in most cases we can be there the same day.
In Chantilly’s 1980s and ’90s subdivisions, the water heater is usually in the basement or, in some homes, the garage. A gas heater in a garage has to sit up on a platform so the burner is off the floor, and we keep that setup when we replace it. Homes of this age often lack a thermal expansion tank, which is now expected on most closed systems, so we add one where needed. We also swap the old cold-water shutoff if it’s stiff or weeping, since it’s the valve you’ll reach for in an emergency. Townhomes usually keep the heater in a small utility closet.
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.
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.
We fill and fire the new heater, check for leaks, set the temperature, and haul the old unit away.
Every water heater replacement is quoted upfront once we have seen the old unit and the space. The price covers the unit, the install, the permit and haul-away. You approve it before any work starts.

Every job is backed by proper training, the right permits, and a workmanship guarantee.
We show up on time, protect your space, and leave the job cleaner than we found it.
For a standard tank swap, plan on a few hours once we arrive. Adding an expansion tank or a new shutoff valve adds a little time. Since Chantilly is close to our Centreville base, the job can often be done the same day you call.
A gas heater in a garage needs to stay raised off the floor and protected from car bumps. We keep or rebuild the platform as needed and make sure the vent and gas line line up with the new unit.
Yes. We drain it, carry it out, and take it away for proper disposal. Fairfax County requires a permit for replacement, even like-for-like, and we pull that and handle the inspection too.
