Gas Line Repair in Oak Forest, IL
In Oak Forest the mains connection is the norm at 91% of households, with 1% on tank propane. Knowing which you have is the first step and it takes one look at the wall.
Read this first
A buried service line and a meter sit on most properties in Oak Forest, where 91% of homes are on mains gas. Federal rules end the utility's service line at the meter outlet, so everything downstream of the meter is the owner's to maintain and repair.
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 Oak Forest 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 Oak Forest | Share |
|---|---|
| Utility (mains) gas | 91% |
| Bottled or tank propane | 1% |
| Electricity | 8% |
| Fuel oil and kerosene | under 1% |
| Wood and everything else | 1% |

Read it as fuel rather than as plumbing. The share on utility gas is how many houses burn it, which is the nearest thing published to how many have a service line. 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. Oak Forest sits 9 points above the state on mains and 1 point below it on propane. That spread is what a state average hides, and it is why this page carries the town’s own figures rather than inheriting them.
Before anyone digs on the property
A locate before digging is free, and PHMSA is unambiguous about the value — excavation damage is the leading cause of pipeline incidents and calling 8-1-1 first avoids one 99 times in a hundred. The gap to ask about is private buried line, which a standard locate may not mark.

What to ask whoever quotes it
Ask how the work will be tested and what happens at the end of it. An inspection on gas work is normal rather than a complication, and a contractor who treats it as one is telling you something.

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. Non-emergency work in Oak Forest goes through this number as well.
