If You Smell Gas or Suspect a Leak
What should I do first if I smell gas in my home?
Leave immediately — get everyone out without touching light switches, appliances, or anything that could spark, and leave the door open behind you. From outside, call 911 and Peoples Gas at 1-866-556-6002. Don’t stay to investigate; a strong smell is an emergency, and the utility response is free and fast. Once the immediate danger is cleared, a licensed fitter handles the private-side diagnosis and repair. Full steps in our who-to-call guide.
What does a gas leak smell like?
Rotten eggs or sulfur — natural gas is odorless, so utilities add a chemical called mercaptan specifically so you can smell even small leaks. Other signs: a hissing sound near a line or appliance, a dead patch of grass over a buried line, an unusually high gas bill, or physical symptoms like headaches and dizziness. Trust your nose; the odorant exists precisely so you’ll act on it.
The gas company came and found nothing, but I still smell gas. Now what?
Trust your nose — a utility safety sweep can miss slow, intermittent, or hidden leaks on your private piping, because it’s a fast hazard check, not a forensic search. Get a licensed fitter to run a private-side instrument detection and, if needed, a pressure test that catches leaks a walk-through can’t. Full explanation in our “found nothing” guide. (If the smell is strong or worsening, treat it as an emergency and call 911 again.)
Is a gas smell always an emergency?
A strong or spreading smell, hissing, or symptoms — yes, leave and call 911 and the utility. A faint, stable odor that comes and goes is still a real signal worth investigating, but not necessarily an evacuate-now situation, especially after the utility has cleared immediate hazard. When in doubt, treat it as an emergency; the utility call is free and erring toward caution with gas is always right.
What’s the difference between a gas leak and carbon monoxide?
They’re different dangers: a natural gas leak smells like rotten eggs and is a fire/explosion risk; carbon monoxide is odorless, comes from incomplete combustion, and is a poisoning risk detected only by a CO alarm or symptoms. Both are emergencies but call for different responses. Our CO vs. gas guide breaks down both.
What Gas Work Costs in Chicago
How much does gas leak repair cost in Chicago?
Most minor repairs run $120–$300, with the citywide average around $210. Leak detection is $75–$400 by scope, a pressure test is $75–$150 per line with a signed affidavit, and the city permit is about $75. Larger jobs — galvanized section replacement ($600–$1,200), buried lines ($1,500–$3,500), full repipe ($2,500–$5,500) — scale with scope. Everything’s published on our Chicago gas cost guide; we don’t do quote theater.
How much does it cost to find a gas leak?
Instrument leak detection runs $75–$400 depending on how much of the system has to be traced. If the smell is intermittent or hidden, a pressure test ($75–$150 per line) definitively proves which line leaks. Once located, most repairs land at $120–$300. See how detection works.
Does homeowners insurance cover gas line repair?
Usually not for the common causes — age, corrosion, and wear are standard policy exclusions, and those cause most Chicago gas failures. Insurance more often helps with sudden accidental damage or with consequential fire/explosion damage a leak causes, even when the pipe itself isn’t covered. Coverage varies by policy — confirm with your carrier. Details in our insurance guide.
Why are some gas quotes so much higher than others?
Often because they’re pricing fear, not work — a vague “gas system concern” gets quoted as a full repipe when the actual fix is a $250 joint. Insist on a diagnosis before a quote: what’s wrong, how it’s fixed, what it costs, itemized. Published pricing and a located problem are the signs of an honest quote; “we’d have to see it” as a permanent posture is not.
Who’s Responsible for What
Who is responsible for a gas leak — me or the gas company?
The dividing line is the meter. Peoples Gas owns and repairs everything up to and including the meter, for free (1-866-556-6002). Everything past the meter — the piping into and throughout your home — is the property owner’s responsibility and the work a licensed fitter handles. Confirming which side the leak is on is the first step, and our who-to-call guide explains it.
Who pays for a gas leak in a rental — landlord or tenant?
Building piping — risers, boiler supply, the lines feeding the structure — is the owner’s responsibility, and in Chicago heat and cooking gas are protected essential services a landlord can’t ignore. A connector on your own tenant-owned appliance is usually yours. Our rental guide maps every scenario and includes the written-notice-then-311 escalation script for unresponsive landlords.
My landlord won’t respond to a gas smell. What can I do?
If it’s an active strong smell, leave and call 911 and Peoples Gas (1-866-556-6002) from outside — that’s free, immediate, and doesn’t require the landlord. Then report in writing; written notice starts the clock toward 311 and the Department of Buildings under Chicago’s essential-services protections. The rental guide has the exact escalation path.
Why won’t my gas come back on after a leak in my building?
Peoples Gas restores service per account, not per building — every meter needs its own passing pressure test called in. In a multi-unit building, if lines are tested one at a time, restoration drags. All lines tested in one visit and all accounts called in together is how a building comes back in a day. Our red-tag restoration guide covers the full tag-to-flame sequence.
