Chicago Gas Leak Detection Services

Chicago's Gas Lines Are Older Than You Think

Chicago’s gas infrastructure dates back to the 1800s. Cast-iron pipes originally installed in 1886 are still being replaced across the city today. In neighborhoods like Logan Square, Pilsen, Bridgeport, and Rogers Park, it’s common to find pre-1970 galvanized pipes running through homes that were built before World War II — pipes that have been quietly corroding for decades without any visible warning sign. Gas leak detection isn’t just for emergencies. It’s for anyone who owns or rents in a city where the ground beneath your home holds infrastructure that was never designed to last this long. A slow leak in a basement apartment or a corroded fitting behind a century-old bungalow wall can go undetected for months — until it doesn’t. We perform professional gas leak detection and gas pipe pressure testing for Chicago homeowners, landlords, and property managers across Cook County. Whether you’re responding to an emergency or being proactive before heating season, we find what’s leaking and fix it right.

What You Get When the Job Is Done Right

A properly completed gas leak inspection doesn’t just find the problem — it gives you documented proof that your home is safe and your gas system is sound.

You stop guessing whether that smell is a real leak or just a pilot light — and get a definitive answer.

You head into Chicago's heating season knowing your gas lines were inspected by someone who actually knows this city's housing stock.

Peoples Gas Shut Off Your Meter

What Happens After Peoples Gas Cuts Your Gas

A lot of Chicago homeowners don’t find out how this works until they’re already in the middle of it. Peoples Gas responds to a reported gas leak, shuts off your meter, and declares the area safe. Then they leave. They do not repair your gas lines — that’s not their job. Before they’ll restore your service, a licensed plumber must locate the leak, complete the repair, and confirm the line holds pressure. That’s where we come in. We handle the full process — detection, repair, and pressure testing — so you’re not left coordinating between multiple contractors while your family sits in a cold house. We’ve done this across Cook County and we know exactly what Peoples Gas needs to see before they restore service. When you call us, we give you a clear quote upfront, show up the same day, and don’t leave until the job is done and documented.

Gas Leak Safety Chicago Winters

Chicago Winters Make a Small Leak More Dangerous

Chicago averages 105 days below freezing. During those months, homeowners seal every gap — storm windows, door sweeps, weatherstripping — to keep the heat in. That’s smart for your energy bill. But it’s also exactly the condition that turns a slow, minor gas leak into a serious indoor accumulation problem. Natural gas becomes explosive at around 9% concentration in air. In a well-ventilated home, a small leak may dissipate before reaching dangerous levels. In a tightly sealed Chicago home in February, that same leak has nowhere to go. Basement apartments — which are extremely common in Chicago’s two-flat and greystone building stock — are especially vulnerable because gas settles in lower spaces. We recommend a gas line inspection before heating season every year, not just when something smells off. If your gas bill spiked without explanation, if you’re moving into an older home in the bungalow belt, or if your building hasn’t had a gas line check in years, that’s reason enough to call. A pressure test takes a few hours. Finding out you have a problem after the fact takes much longer.
