Temple Hills homes on natural gas are on Washington Gas, so if you smell gas, leave the house and then call 911 and Washington Gas at 844-WASHGAS (927-4427), option 1, from a safe place. For leaks on the house side of 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 Temple Hills.

Temple Hills is mostly garden apartments, duplexes and single-family neighborhoods built from the 1950s through the 1970s, with a median build year of 1973. That means a lot of gas piping that is fifty years old or more, often still working but altered many times. The Temple Hills mailing area, ZIP 20748, is wider than the community itself, but the gas and permit setup is the same county-wide.
What to do now
- Leave at the first sign of a gas odor. Don't light anything, flip switches or start a car in an attached garage.
- Call once you're outside. Dial 911, then Washington Gas at 844-WASHGAS (927-4427), option 1. In a duplex or apartment, warn neighbors on your way out.
- Wait for the all-clear. Washington Gas or the fire department will tell you when it's safe.
- Get the house side fixed. If the leak is past the meter, a plumber repairs it and tests the line before service resumes.
- For non-urgent concerns, such as yellow flames or a stubborn pilot, book a daytime visit.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Odor near the kitchen range | Aged connector or a valve leaking at the stem |
| Water heater burner sputters | Dirty burner, draft issue or restricted supply |
| Furnace and stove both weak at once | Line too small for the combined load |
| Hiss at the meter area | Leak at a fitting near the meter; leave and call the utility |
| Soot around a vent | Incomplete combustion; have it checked promptly |
What affects the cost
Most Temple Hills gas calls are repairs to existing pipe or reconnections during a water heater or furnace change, and those cost less than new runs. Price rises with distance from the meter, finished walls in the way, and any need to upsize a line that has picked up extra appliances over the decades. In shared buildings, access to utility rooms can add time. Prince George's County DPIE issues building permits but no plumbing permits; WSSC Water issues and inspects those. Water heater replacement needs a permit, and WSSC requires gas water heater and furnace replacements to be done by a plumber or gasfitter holding a WSSC license, so the permit is part of the price.
