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 · Reston, VA
Quick answer
LeMaster Plumber replaces water heaters in Reston homes of every type, from Lake Anne’s original village to South Lakes and Hunters Woods. Many Reston cluster homes and condos keep the heater in a closet only a little wider than the tank, so we measure the height, width, and door clearance before we bring the new unit. Fairfax County requires a permit for the swap, and we take care of it. Call (703) 832-9090 to get on the schedule.
In a Reston condo, the water heater may sit right above a neighbor’s ceiling, so a drain pan with a proper outlet is a must. Some condo associations ask for notice before plumbing work, set work hours, or have management shut off the building water. We work within those rules. Cluster townhome associations may also limit where vents can exit an outside wall, which matters if you’re weighing a tankless unit to free up closet space. Fairfax County requires a permit for water heater replacement, even like-for-like. 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.
Water heater replacement is permitted work. We pull the permit and handle the inspection so you do not have to.

We check its age, the leak or failure, the fuel type, the venting and the space, and confirm replacement is the right call.

Why LeMaster Plumber
You approve the price before we start — no surprises and no pressure. You’ll always know the cost before any work begins.
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.
It’s smart to check. Some Reston associations want advance notice, a certificate of insurance, or set hours for plumbing work. We’ll provide what they ask for and plan the day around their rules.
Usually. Newer tanks can be a bit wider than older ones because of added insulation, so we measure the closet and doorway first. If a standard tank won’t fit, we’ll show you a slimmer tank or a tankless option.
We drain the old tank fully before moving it, lay down floor protection, and set the new heater in a drain pan piped to a safe outlet. That pan is your backup if the tank ever leaks later on.
