Gas Line Repair in Naperville, IL
Naperville is a mains gas town — 86% of households heat with utility gas. The useful thing to know before anything goes wrong is where the utility’s responsibility stops.
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 Naperville, where 86% 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 Naperville is supplied
Two questions hide behind one. Where does the regulated line end — the federal answer is the meter outlet. And who pays for a repair on either side of that — which is tariff and state regulation, and varies.
The second one is the one that costs money, and it is answered by your utility rather than by any rule you can look up.
| Households in Naperville | Share |
|---|---|
| Utility (mains) gas | 86% |
| Bottled or tank propane | 1% |
| Electricity | 12% |
| Fuel oil and kerosene | under 1% |
| Wood and everything else | 1% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 61,065 occupied housing units. The table counts heating fuel rather than pipework. A house on mains gas almost certainly has a service line; the Census does not say so directly and neither do we. 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. Naperville sits 5 points above the state on mains and 1 point below it on propane. That distance from the state average is the whole argument for publishing a town figure at all.
Before anyone digs on the property
The single most dangerous thing most people will ever do to a gas line is put a spade through it. PHMSA calls excavation damage the leading cause of pipeline incidents; 8-1-1 is a nationwide toll-free number to call before any excavation, and calling it gives a 99 percent chance of avoiding an incident.

What to ask whoever quotes it
If any part of the job is in the ground, ask when they are calling 8-1-1 and whether a private line may be in the way. Both answers should come before the excavation, not during 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 Naperville calls us about.
