Water Heaters · Chantilly, VA
Quick answer
LeMaster Plumber services tank and tankless water heaters across Chantilly, including Greenbriar, Poplar Tree, and Rocky Run — and as your Centreville neighbors, we get there fast. Many Chantilly homes still have their original 1990s heater, now well past its expected life. Call (703) 832-9090 for same-day, upfront-priced water heater service in Chantilly.
A lot of Chantilly’s homes were built in the late 1980s and ’90s, which means the original water heaters are now well beyond the typical 8–12 year tank lifespan — and we replace plenty of them before and after they fail. Being based next door in Centreville, we can usually get to Chantilly the same day. We’ll tell you whether your aging unit has life left or it’s time for a right-sized replacement.
Heating elements, thermostats, gas valves, pilot and igniter problems, leaking valves, and no-hot-water diagnostics for tank and tankless units.
Right-sized gas or electric tank water heaters installed to code, with new connections, a fresh drain pan, and proper venting.
On-demand tankless units for endless hot water and lower standby energy loss — sized to your home’s real demand.

A leaking tank can flood a basement fast. We respond quickly, shut it down safely, and get hot water restored.
We test the heater’s components and check its age and condition to find out why you have lost hot water.
We lay out the honest math: the cost to repair versus replace, and which gives you more reliable hot water for the money.
If you replace, we size the tank or tankless unit to your household’s real demand so you never run short or overpay.
We install with proper venting, connections, and safety valves, then test everything and haul away the old unit.
