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 · Herndon, VA
Quick answer
LeMaster Plumber replaces water heaters in Herndon, from established homes near the Town Green to townhomes in Kingstream and Chandon. In many Herndon townhomes the heater is on the lowest level beside finished rooms, so a new drain pan and a proper expansion tank are part of doing the swap right. Fairfax County requires a permit for replacement, and we handle it. Reach us at (703) 832-9090 to set a time.
Herndon’s housing runs from older homes near the Town Green to newer communities along the Dulles corridor, and the water heater setup varies with it. Some townhomes have an electric tank in a lower-level closet, where the job comes down to a careful carry-out through finished halls and a clean hookup. Older gas units in established homes need their draft hood, vent connector, and gas shutoff checked as the new tank goes in. On every job we pipe the temperature-and-pressure relief valve to a safe spot and test the new heater before we leave.
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.

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.
Rusty hot water, water pooling at the base, popping noises, or hot water that runs out faster than it used to. If the tank is in the 8–12 year range and showing any of these, it’s worth planning a replacement before it fails.
Usually the fuel you already have, since switching adds work. Gas heats back up faster; electric is simpler to vent. If both are available, we’ll explain the trade-offs, and your upfront price is approved before we start.
Yes. Fairfax County requires a permit for water heater replacement, even like-for-like. We pull it and handle the inspection.
