Hot water again, often the same day.
Water heater installation, replacement and yearly maintenance in Herndon, Reston, Sterling, Great Falls and across Northern Virginia.

A water heater lasts about ten years in good conditions. After that, gas, electric and tankless units all start to lose efficiency, and tanks start to leak. When yours quits, we install the replacement, often the same day, and look at whether a different type would suit the house better.
We also install the add-ons that make hot water better. An expansion tank takes pressure off your plumbing. A mixing valve keeps the temperature safe and stretches the hot water. A Watts recirculating pump puts hot water at the faucet in seconds instead of minutes.

No heat, no cooling, or no hot water?
Call and a real person picks up, any hour. We find the cause and give you your options before any work starts.
For many homes, yes: endless hot water, a smaller footprint and lower running costs. It depends on your gas line, venting and how much hot water you use at once. We will tell you honestly whether it fits.
When water heats, it expands. Without somewhere to go, that pressure pushes on every pipe and fitting in the house. An expansion tank gives it room and helps the plumbing last.
Often, yes. Call (571) 910-9901 early in the day and tell us what you have now.
