Water Heaters · Great Falls, VA
Quick answer
LeMaster Plumber repairs and installs tank and tankless water heaters throughout Great Falls, including the large estate homes along Georgetown Pike and Seneca Road. Big homes need serious hot-water capacity, and many Great Falls properties on well water benefit from treatment too. Call (703) 832-9090 for water heater service in Great Falls.
Great Falls estate homes often have multiple bathrooms and high hot-water demand, so sizing the system correctly matters — sometimes a high-capacity tank, a tankless setup, or multiple units. Many of these homes are on private well water, which can carry sediment or minerals that shorten a heater’s life, making water treatment worth considering. We match the system to your real demand and lay out the options clearly.
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.
Annual tank flushing removes sediment that shortens lifespan and drives up your energy bill — especially with NOVA’s hard water.
Thermal expansion tanks, temperature-and-pressure relief valves, and shutoffs installed and replaced to keep the system safe.
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.
Every water heater repair and installation is quoted upfront before we begin. We give you the repair-versus-replace numbers side by side so you can make the call that is right for your home and budget. You approve the price before any work starts.
