Smells Like Rotten Eggs? Here Are 5 Ways to Detect a Gas Leak

by BROOKE GOLD HASSON | Feb 03, 2016

GasLeakNatural gas accounts for nearly one-fourth of all energy consumption in the U.S., and more than 600,000 Floridians use it in their homes, according to the American Gas Association. Generally speaking, natural gas is a safe, clean, and cost-efficient way to heat your home and power your appliances. 

But as we’ve seen all too often lately, a small gas leak can quickly escalate into a dangerous explosion, sometimes with deadly consequences.

How do you know if your home has a gas leak? Be on the lookout for the following warning signs:

“Rotten Egg” Smell: In its native state, natural gas is odorless. To help protect homeowners, utility companies add mercaptan – a harmless chemical that smells like rotten eggs – to natural gas. So if you get a whiff of that “rotten egg” smell, it’s possible that a gas leak is present.

Hissing or Blowing Sound: Another common warning sign of a gas leak is an unusual hissing or blowing sound near a gas line or gas appliances like stoves and washing machines.

Spiraling or Swirling Dirt: If you see dirt blowing around in your yard when there’s little or no wind, this may indicate the presence of a gas leak in an underground utility line.

Bubbling Water: Standing water does not bubble on its own – so bubbles in standing water may signal a broken gas pipeline.

Dead or Discolored Vegetation: Nature or natural gas? Over time, most plants and vegetation will brown or change color naturally. However, a clump of dead or discolored vegetation surrounded by green and healthy vegetation may suggest the presence of a natural gas leak.

If You Suspect a Gas Leak…

If you suspect a gas leak in your home, it’s important to act quickly – while being sure to keep personal safety in mind. 


  • Do evacuate your house immediately. Open doors and windows for ventilation and extinguish any open flames, if possible.
  • Do turn off any equipment being used in or near the suspected leak, and move upwind from the source of the leak.
  • From a safe location, do call 911 or your local emergency response number and utility company.
  • Do warn others to stay away when possible. 


  • Don’t light a match, start a car engine, use a telephone, operate an electrical switch, or do anything that may create static or spark.
  • Don’t re-enter your home until a public utility official has inspected the premises, made all necessary repairs, and determined it to be safe.
  • Don’t touch, breathe in, or make contact with any leaking liquids or gas.
  • Don’t attempt to operate valves.

Preventing Gas Leaks

Not all natural gas leaks are preventable, but there are steps you can take to significantly reduce the likelihood of a gas leak incident in or near your home:

  • Make sure gas appliances are properly installed and maintained. Consider having gas appliances inspected by a qualified technician at least once a year.
  • Keep all combustible materials away from gas appliances.
  • Install a gas detector in your home. You can purchase one at your local home improvement store for as little as $25.
  • Because many natural gas leaks are the result of damaged underground utility lines, before you dig – whether you’re planting shrubs, replacing a mailbox post, or installing a fence – call 811. That’s the federally designated number to call before digging to protect yourself and others from unintentionally hitting underground utility lines.
