A gas leak rarely announces itself with a bang. It usually starts small: a faint smell, a soft hiss, a headache that fades outside. Natural gas is odorless on its own, so utilities add mercaptan, which gives leaks their rotten egg smell. That smell can fade or go unnoticed, though, which is why it helps to know all seven warning signs, particularly in Nassau County, where many homes still run on original gas lines and appliances decades old.
The 7 Gas Leak Warning Signs to Watch For
1. Rotten Egg Smell
The most common sign of a gas leak is a strong smell, like rotten eggs or sulfur, from mercaptan added to natural gas, which has none of its own. It’s strongest near appliances, meters, or connections. You should never try to identify the source of the smell. Get out of the house and call for emergency help — this needs a professional to handle it safely.
2. Hissing Sound
A hissing sound heard continuously near a gas pipeline or gas equipment, even when the equipment is switched off, indicates a gas leak under pressure. Such a situation could be caused by damage to the gas line or a broken valve. Do not examine it on your own. Leave the area right away and call emergency services.
3. Dead Plants
If there is a gas leak in the ground, it displaces oxygen and can kill the shrubs above. A dead patch that keeps returning near a gas line is worth a look. Don’t dig it up yourself; have Order A Plumber safely trace the source
4. Higher Gas Bills
An undetected leak will increase your consumption without changing anything about your house. When a sudden change does not correlate with either of these things, contact Order A Plumber to check your lines and appliances before assuming it’s a billing error.
5. Outdoor Bubbles or Dust
Gas escaping from underground piping will appear in the form of bubbles coming out of a puddle or blowing dust on the ground, indicating a bigger leak outside. Stay clear of the area and report exactly what you saw.
6. Physical Symptoms
Breathing in small amounts of gas indoors can give you headaches, make you feel dizzy, or nausea. If you feel better outside but the symptoms come back when you go back inside, act as if there is a leak. Get everyone out right away and call a professional.
7. Orange Pilot Light
A healthy flame burns blue. Orange, yellow, or flickering flames can mean incomplete combustion due to a dirty burner or a leak at the connection. Turn off the appliance if you can safely do so, and have Order A Plumber inspect it.
Gas Leak Safety for Nassau County Homeowners
Many homes in towns like Freeport, Long Beach, Levittown, and Garden City run on original steel piping and older appliances, which are more prone to corrosion near the salt air of South Shore towns. That’s why it helps to have a local company like Order A Plumber who knows the housing stock. If there is an emergency, leave right away and contact emergency services. Once you are safe, Order A Plumber will follow up to determine what happened and handle the repairs.
What to Do — and What to Avoid
If you notice any of these signs, act the same way every time:
- Leave the house immediately with everyone, including pets.
- Don’t use light switches or anything that could spark.
- Call your gas utility’s emergency line or 911 from a safe distance.
- Stay outside until a professional confirms it’s safe to return.
- Never try to find or repair the leak yourself.
