If you smell gas in an Arlington home, get everyone outside, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from a safe spot. Leak repairs and new gas lines on your side of the meter are plumbing work that Arlington County permits and inspects. Call the number on this page to be connected with a local plumber in Arlington.

Clues that the gas piping needs attention
- A rotten-egg smell. Utilities add that odor so a leak can't go unnoticed. Leave first and phone from outdoors.
- A soft hissing sound at a valve, union or appliance connection
- Range burners that burn orange or ragged instead of a steady blue
- Scorching or dark film around the furnace or water heater vent
- A pilot that keeps going out on an appliance that used to be reliable
Only the smell means clearing the house. The rest are reasons to schedule a visit soon, before a slow fitting leak or a combustion problem gets worse.
Gas work in Arlington
Washington Gas delivers natural gas across the region, and Arlington homes with gas service are on its system. The utility looks after the main and meter; the pipe that leaves the meter and feeds the furnace, water heater, range and dryer belongs to the property owner. That house-side piping is what a plumber repairs, extends or replaces.
Arlington is a county with no separate city government, so Arlington County's building and inspections program handles plumbing, gas and water heater permits, with applications filed through the Permit Arlington portal. New gas piping, a relocated range or a line for a new appliance should be expected to go through that process, with an inspection before the gas is turned on to the new section.
The median Arlington home was built in 1976, and the county mixes high-rise buildings along the Rosslyn-Ballston corridor with older single-family streets. Older houses often carry threaded steel gas pipe that has been tapped and extended through several kitchen and laundry remodels. In condo and apartment buildings, gas piping beyond your own unit is usually the building's responsibility, so check with management before booking work.
What moves the price
- How far the new line runs from the meter or nearest branch, and whether walls or ceilings must be opened
- Whether the existing pipe can carry another appliance or needs a larger trunk
- Pipe type (threaded black steel or flexible stainless tubing) and the number of fittings and shutoffs
- The County permit and inspection
- Patching drywall or plaster afterward
