Fort Washington homes with natural gas are generally on Washington Gas, so a gas smell means leaving the house first and then calling 911 and Washington Gas at 844-WASHGAS (927-4427), option 1. For leaks past the meter, new appliance lines and gas water heater or furnace replacements, call the number on this page to be connected with a local plumber in Fort Washington.

Fort Washington was mostly rural until about 1960 and is now a Potomac riverfront suburb, with the median home built in 1980. Washington Gas serves Prince George's County, though BGE serves some parts of it, so check your bill if you're unsure. Larger lots here make outdoor gas lines for grills, pool heaters and standby generators common requests.
What to do now
- Smell gas? Get out. Leave doors as they are, avoid switches and phones indoors, and move well away from the house.
- Make the calls from outside. Call 911 and then Washington Gas at 844-WASHGAS (927-4427), option 1.
- Stay out until cleared. The utility or fire department decides when it's safe to return.
- Arrange the repair. If the leak is on your side of the meter, service may stay off until a plumber fixes it and the piping passes a test.
- Planning new gas work? List the appliances you want to add and their locations so the plumber can size the line.
Symptoms and what they usually mean
| Symptom | Likely cause |
|---|---|
| Gas odor near an outdoor appliance | Loose fitting, damaged connector or a leak on a buried line |
| Grass dying in a strip across the yard | Possible leak on an underground gas line |
| Generator or pool heater struggles at startup | Line undersized for the added load |
| Orange flames on the cooktop | Burner needs cleaning or air adjustment |
| Water heater pilot keeps failing | Thermocouple, draft or supply issue |
What affects the cost
Outdoor work is often the biggest variable here. A run to a detached garage, a patio or a generator pad means trenching, pipe rated for burial, and a Miss Utility locate before digging. Indoors, price depends on the distance from the meter, whether the main line needs upsizing for the added demand, and how much finished wall stands in the way. Prince George's County says all plumbing permits are issued by WSSC Water, and WSSC requires gas water heater, furnace and gas appliance replacements to be done by a plumber or gasfitter holding a WSSC license, so the permit and inspection are part of the job. Replacing several old valves or connectors at once usually costs less than doing them one visit at a time.
