Gas Line Repair in Thornton, IL
In Thornton the mains connection is the norm at 83% of households, with 0% on tank propane. Knowing which you have is the first step and it takes one look at the wall.
Read this first
The utility's regulated line ends at the meter outlet and the piping beyond it belongs to the property owner. That boundary decides most gas line questions in Thornton, where 83% of households heat with utility gas and a buried service line runs from the street on most properties.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Thornton is supplied
Everything upstream of the meter outlet is the operator’s service line under 49 CFR § 192.3. Everything after it is customer piping under local code. That single point is what a contractor establishes before quoting.
It is also why the answer to "is this my problem" is sometimes no, and why it is worth asking before assuming it is yes.

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Illinois as a whole, 82% of households are on mains gas and 2% on tank propane. Thornton sits about level with the state on mains and 2 points below it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
Before anyone digs on the property
Digging is the risk, not age or material. PHMSA names excavation damage as the leading cause of pipeline incidents and puts a caller’s chance of avoiding one at 99 percent. 8-1-1 is nationwide, toll-free, and costs nothing.

What to ask whoever quotes it
Ask how much gas work they actually do, not whether they can. Gas is separately licensed in most jurisdictions and plenty of capable plumbers do very little of it.

Checking a plumber in Illinois
Illinois licenses are issued by the Illinois Department of Public Health, Plumbing Program, which publishes a public search you can use before work begins.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Gas is one part of what Thornton calls us about.
