How to Check for a Gas Leak — and What to Do If You Find One

Natural gas is odorless by nature, but utility companies add a sulfur-like "rotten egg" smell so you can detect leaks. If you notice this smell, do not ignore it — even a small leak can lead to an explosion. Do not turn on lights, strike matches, or use your phone near the suspected area, as any spark can ignite the gas.

Open windows immediately, get everyone out of the building, and call your gas company's emergency line or fire department from outside. If you suspect a small leak but are not sure, apply soapy water to gas connections and watch for bubbles. Never try to repair a gas leak yourself. Install a carbon monoxide and gas detector in your home — they cost little and can alert you before the smell becomes noticeable.
