If you smell gas in a Germantown home, get everyone outside first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from a safe spot. Repairs and new piping on the house side of the meter go through a WSSC Water gasfitting permit, so call the number on this page to be connected with a local plumber in Germantown.

What happens when you call
The number on this page links you with an independent plumber who takes gas piping jobs in Germantown. Plumber Washington DC Pros is a referral line, so the visit, the price and the schedule are worked out directly between you and that plumber. Have a few details ready: whether this is a repair or an addition, which appliance is involved, where it sits relative to the meter, and whether the house is a townhouse or a detached home.
For a suspected slow leak, the plumber usually shuts the supply, checks joints and valves with a gas detector or a bubble solution, repairs the bad fitting and then tests the system before relighting pilots. For a new branch, the line is sized for the added load, run with its own shutoff, pressure tested and inspected before gas is turned back on to it.
What moves the price
- How far the new appliance sits from the meter and how the pipe gets there (finished basement ceiling, garage wall, crawlspace)
- Whether the existing trunk can carry another appliance or needs upsizing
- Black steel pipe versus flexible stainless tubing, and the number of fittings and shutoff valves
- The WSSC Water permit and the inspection visit
- Drywall or ceiling patching once the run is closed in
Gas work in Germantown
Germantown is unincorporated Montgomery County, about 23 miles up I-270 from downtown Washington. That puts gas and plumbing permits with WSSC Water rather than the county; Montgomery County's Department of Permitting Services handles building permits for larger remodels. WSSC requires all gas work in its area, including furnace, gas water heater and gas appliance replacements, to be done by a plumber or gasfitter holding a WSSC license, under a WSSC permit.
The community grew fast once public sewer reached it in the 1970s, and in ZIP 20874 the biggest share of homes went up in the 1980s, with fewer than one in five built before 1980. Piping from that era is generally steel and often sound, but it has usually been added to over the years: a gas range swapped in for an electric one, a fireplace insert, a larger water heater. Those additions are where undersized branches and tired connectors turn up.
Washington Gas is the utility for Germantown, though Maryland's consumer advocate notes BGE serves parts of the county, so the name on your bill settles it.
Before the plumber comes
- Clear the path to the meter and to each gas appliance
- Find the model plate or input rating on any new appliance
- Note which pilots will need relighting afterward
- If you live in a townhouse community, check whether the HOA cares about exterior pipe routing
