7 Signs You May Have a Gas Leak
When gas escapes, your senses are the first alarm. Knowing what to look for helps you react before the situation gets worse.

Natural gas has no scent, but suppliers add a chemical called mercaptan to help people detect leaks.
- Strong sulfur or rotten egg smell
- It may come in waves or linger
- A major red flag for signs of a gas leak at home
2. Hissing or Whistling Sounds
Gas can escape through cracks, fittings, or loose pipes.
- A high-pitched hiss near appliances
- Especially noticeable when it’s quiet
- It’s one of the key gas leakage symptoms you shouldn’t ignore
