Gas Line Repair in Lake Forest, IL
Most of Lake Forest is on the gas main: 84% of households. That means a meter on the wall and a service line under the ground, and a boundary between them that federal rules put in a specific place.
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 Lake Forest, where 84% 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 Lake Forest is supplied
49 CFR § 192.3 fixes the end of the service line at the meter outlet. It is a precise answer to a narrow question, and it is not the same as who is responsible for repairs, which varies by utility and by state.
Establishing which side of the meter a fault is on is the first thing any contractor should do, because it decides whether they are the right person to call.
| Households in Lake Forest | Share |
|---|---|
| Utility (mains) gas | 84% |
| Bottled or tank propane | under 1% |
| Electricity | 15% |
| Fuel oil and kerosene | under 1% |
| Wood and everything else | under 1% |

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. Lake Forest sits about level with the state on mains and 2 points below it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
Excavation damage remains the leading cause of pipeline incidents according to PHMSA. That is not a fact about pipelines so much as a fact about gardening, and the prevention is one free call to 8-1-1 before the first spade goes in.

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