Gas leaks are a scary and, unfortunately, relatively common problem.  Over 65 million homes in the United States use natural gas or liquid propane in order to power stoves, ovens, water heaters, and more. While natural gas is one of the safest and cleanest fossil fuels, its highly combustible nature means it is crucial for homeowners to recognize the signs of a gas leak.


You may smell a gas leak before noticing any other sign. While both natural gas and liquid propane are colorless and odorless, companies have added a smell to help homeowners easily identify a leak. If you smell something similar to rotten eggs or cabbage, you may have a gas leak.


Gas leaks will occasionally make hissing sounds. (Note that if you can hear a gas leak, you will also be able to smell it.) Hissing sounds are incredibly dangerous as they mean an excessive amount of gas is escaping. In this case, you, your family, and any pets should leave the house, and a utility company should be contacted immediately.

House Plants

A buildup of gas in the air may cause your house plants to die. If seemingly thriving plants are suddenly brown and drooping, it may be the result of a gas leak.

Change in Pet Behavior

If your pets suddenly change their behavior, including becoming lethargic, suffering a lack of appetite, vomiting, or other out-of-place symptoms, they may have detected a gas leak before you have.


Gas leaks can often affect your health, causing dizziness, breathing difficulties, and even flu-like symptoms. If these symptoms seem to sprout up suddenly and can’t be attributed to a cold or allergies, it’s recommended to check your home for a gas leak.
