Greenbelt is served by Washington Gas, so if you smell gas, leave the house and then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, from outside. For repairs on the house side of the meter, new appliance lines and gas water heater swaps, call the number on this page to be connected with a local plumber in Greenbelt.

What happens when you call
The number on this page puts you in touch with an independent local plumber who takes gas work in Greenbelt. Be ready to say what the job is: a suspected leak, a new line for a range or dryer, a water heater or furnace replacement, or an outdoor line. Mention whether you live in a detached house, a townhouse or one of the cooperative row homes, since shared walls and common areas can affect access. If there is any gas odor, though, skip the details and get outside first; Washington Gas and 911 come before a plumber.
On site, the plumber traces the piping from the meter, checks fittings and valves with a leak detector or soap solution, and confirms the line is sized for what it feeds. New piping is pressure-tested before the gas is restored, and each appliance is relit and checked.
What affects the cost
- Whether the job is a fitting repair, a new branch or a resized main run
- Pipe length and how much masonry, plaster or finished ceiling is in the way
- Number of shutoff valves, sediment traps and appliance connectors
- WSSC Water's permit and inspection, plus a City of Greenbelt permit where a county building permit is involved
- Coordination with neighbors or a housing cooperative for shared walls
Local conditions in Greenbelt
Greenbelt began as a planned New Deal community in the 1930s, and its historic core around Roosevelt Center is a National Historic Landmark District. The city's median home was built in 1976, so housing ranges from the original Art Deco-era rows to postwar and later development. Gas piping in older homes has often been modified many times, with newer runs joined to original pipe.
Permits come in layers. WSSC Water handles plumbing and gasfitting permits and inspections, and most gas work must be done by a plumber or gasfitter holding a WSSC license. The City of Greenbelt adds its own requirement: projects that need a Prince George's County building permit must also get a city permit. A simple gas fitting repair rarely triggers that, but a kitchen remodel that moves the range can.
Before the plumber arrives
- Clear a path to the meter, the furnace, the water heater and the appliance in question
- Find your gas bill so the account and utility are at hand
- Note the make and model of any new appliance being connected
- Let your cooperative or HOA know if work affects shared walls
- Move pets and anything stored against the furnace or water heater
