Why McHenry Calls Us

Gas Service Built for McHenry Homes & Businesses

Waterfront cottages converted to year-round homes are a McHenry specialty case — gas systems added piecemeal over decades, with undersized lines and improvised splices the usual finds. Downtown's older housing adds classic corrosion calls, and the Route 31/120 corridors keep commercial work steady.

Gas Emergencies in McHenry: What to Do

If you smell that telltale rotten-egg odor anywhere in your McHenry home or business — basement, near the furnace, behind the range — treat it as real. Get everyone outside, including pets, and avoid switches, plugs, and open flames on your way out. Once you're a safe distance away, call us at (708) 381-2959, or 911 if you sense immediate danger.

McHenry's converted river and lake cottages deserve a full trace-and-test — their gas piping was rarely designed as a single system. Our overnight and holiday dispatch exists for exactly those calls. A technician heads your way — typically arriving in 30–60 minutes — to locate the leak with an electronic detector and shut down the hazard.

Nicor Gas is responsible for the service line up to and including your meter; everything past the meter — house lines, valves, and appliance connections — is where we work. If you're not sure which side the problem is on, call us and we'll help you make the right call quickly.

Common McHenry Gas Problems We See

The local building mix produces a predictable set of issues:

  • Piecemeal gas systems in converted river and lake cottages
  • Vintage piping corrosion in the older downtown blocks
  • Aging fittings in 1980s–2000s subdivisions
  • Failed flex connectors behind ranges and dryers after an appliance swap
  • Leaking valves and unions at furnaces and water heaters after hard winters
  • Buried lines to detached garages, grills, and fire pits that corrode over time

Keeping McHenry Gas Lines Safe

The most reliable way to avoid an emergency is a periodic leak-and-pressure check, particularly before heating season. For older McHenry buildings, we recommend an inspection of the visible piping every year or two; corrosion on black iron and galvanized pipe happens slowly and silently until a joint finally weeps. For newer construction, the priority is the connection points — connectors, valves, and CSST fittings — which is where most modern leaks begin.

Any time you add or move a gas appliance — a new range, a patio grill line, a garage heater, a pool heater — have the connection leak-tested and permitted. It protects your family, keeps the work on record for resale, and avoids problems with the City of McHenry inspection. We handle the permit and the test as part of the job.

Worth verifying. Converted cottages typically gained gas in stages — a heater here, a range there — leaving undersized or oddly routed lines. We map the system, test it, and bring it to code.
Absolutely. Even in newer construction, leaks commonly start at appliance connectors, valves, and CSST fittings rather than the pipe itself. A quick leak-test catches them before they become dangerous.
