In Oakton, a burst pipe or sewage backup calls for shutting the main water valve right away, and a gas smell means getting outside before calling 911 and Washington Gas. Then call the number on this page to be connected with a local plumber in Oakton.

The call itself
Calling the number on this page connects you with an independent plumber who takes urgent work in Oakton. You'll be asked what failed, whether water is still running, whether the main is off, and where the house is; a reference point like Route 123, Interstate 66 or the Oakton Library helps. Ask how after-hours rates work before the plumber is on the way. Arrival depends on the hour and the plumber's schedule, so none is promised.
Cost factors
- Hour and day. Night, weekend and holiday calls usually cost more.
- Where the leak is. An open basement is faster than a finished ceiling or a tiled shower wall.
- What needs replacing. A valve or hose is a small job; a water heater or a section of lateral is bigger.
- Permits. Fairfax County requires a permit for gas water heater and furnace replacements even when they're like-for-like, filed through PLUS.
Utilities in Oakton
Oakton sits between the City of Fairfax and Vienna, and its water can come from either of two places. Most homes are Fairfax Water customers (703-698-5800, with an automated after-hours option). But the Town of Vienna's water system also serves customers outside town limits, so some Oakton homes near Vienna are on Vienna water and sewer instead; Vienna's water and sewer office is 703-255-6385. Your bill settles it.
For Fairfax Water homes, the utility owns the meter and its setting, and the homeowner owns every pipe on the property, including the service line from the meter to the main shutoff in the house. Sewer is usually Fairfax County's: its 24-hour backup line is 703-323-1211, and the private lateral is the owner's. Gas is Washington Gas; with any odor, leave and call 911 and 844-WASHGAS (844-927-4427), option 1, from outside.
The median home in Oakton was built in 1983, and water heaters, aging valves and supply lines in houses of that age still fail at bad times.
Before the plumber gets there
- Keep the main closed and drain the lines from a low faucet.
- Turn off the water heater's gas or power if it's involved.
- Shut off breakers to wet areas.
- Have your water bill handy so you know whether you're on Fairfax Water or Vienna water.
- Photograph the damage.
