Emergency Plumber in Herndon, VA

Inside the town or outside it?

Herndon's mailing addresses reach well past the town limits, and that changes who you call. Inside the Town of Herndon, Public Works runs the water and sewer systems, buying its drinking water from Fairfax Water's Corbalis plant on the Potomac; the Town Operations Division is at 703-435-6860. Herndon-addressed homes in unincorporated Fairfax County, such as areas south of the Dulles Toll Road, are generally on Fairfax Water and Fairfax County sewer instead. Your water bill tells you which.

Gas follows a similar split. Columbia Gas of Virginia serves the town, while some Herndon-addressed areas outside it are on Washington Gas. The utility on your gas bill is the one to call.

The median home in Herndon was built in 1983, so many houses still have their original valves and drain lines alongside newer water heaters. The town reports that no lead service lines have turned up in its service line inventory.

Who to call

Signs that can't wait

• Water spreading from a ceiling, wall or cabinet
• Sewage in a basement drain or the lowest toilet
• A puddle forming under the water heater
• No water anywhere in the house
• Any smell of gas, which means leaving first and calling from outside

Timing and permits

Pipes in exterior walls and above garages split during hard freezes, and summer thunderstorms test basement drains and sump pumps across the area. If the fix turns into a water heater replacement or gas work inside the town, plumbing and gas permits come from the Town of Herndon's Building Inspections office; outside town limits, Fairfax County Land Development Services handles them. Night and weekend calls usually cost more, and no arrival time is promised. A landmark such as Elden Street or the Herndon Metro station helps the plumber find you.
