Gas Line Services in Herndon, VA

Gas service and permits in Herndon

Herndon is an incorporated town with a historic downtown, but its mailing addresses also reach into unincorporated Fairfax County, including areas south of the Dulles Toll Road. That split affects two things: who supplies your gas and who issues your permit.

Inside town limits, the gas utility is Columbia Gas of Virginia, with Dominion Energy for electricity. Fairfax County says residents in parts of Herndon may be on Columbia Gas while most county residents are on Washington Gas, so homes just outside the town can be on either. The utility named on the bill is the one to call in an emergency.

Permits follow the town line. The Town of Herndon's Building Inspections office, part of Public Works, issues Plumbing/Gas trade permits for work inside town limits, with applications sent by email. Outside the town, Fairfax County Land Development Services issues them through PLUS.

The median Herndon home was built in 1983. Downtown has older houses that have been remodeled many times, while homes from the 1980s, the era of the median house, usually still have their original steel gas piping.

Repair or add on?

Signs to take seriously

• A sulfur smell indoors or near the meter: leave and call from outside
• Yellow or flickering burner flames
• A hiss near a valve or appliance connector
• Soot on walls or ceilings near vents

Timing notes

Herndon winters bring the heaviest gas use, so furnace and water heater problems cluster in the first cold weeks. Book outdoor gas projects for spring or summer, when trenching is easier. If you're converting to tankless or adding a large appliance, check with your utility early about meter capacity. Townhouse owners should also confirm whether an HOA needs to approve exterior pipe, vents or wall penetrations before the work is scheduled.
