Seasonal PrepUpdated July 17, 2026
Gas lines are essential to how our homes in Elwood operate, but trouble with these systems is nothing to ignore. With winter temperatures dropping well below freezing and older homes using aging supply lines, the risks of leaks go up, especially during seasonal shifts when pipes contract and expand. Every homeowner in our area should know the early warning signs of a gas leak and understand the steps to take if something's not right.
Why Gas Leaks Matter in Elwood Homes
Most houses in Elwood use natural gas for heating, hot water, and in some cases for appliances like stoves or dryers. Many of these homes are between 30 and 70 years old, and original gas piping may be steel or even older materials that don't age as well as modern lines. The freeze-thaw cycles common in Will County winters put extra stress on both buried and exposed pipes. Even newer developments aren't immune, as shifting clay-rich soils can move underground lines, weakening joints or couplings.
Common Causes of Gas Leaks
From our experience handling gas line services in the southwest suburbs, gas leaks often happen because of:
- Corroded steel pipes in older homes
- Loose fittings around meters, valves, or appliances
- Damage from minor foundation shifts or home projects
- Old shutoff valves or connectors that no longer seal properly
- Accidental hits during yard work or renovation
Homeowners who have updated kitchens or installed new appliances should also double check that all connections are properly sealed. Our faucet and fixture installation team sees plenty of kitchens where a new appliance hookup leaves a vulnerable spot.
Warning Signs You Need To Watch For
Natural gas is colorless and odorless, but utility suppliers add mercaptan to give it a rotten egg smell so leaks are easier to catch. Don't count on smell alone. We recommend every homeowner stay alert for these signs:
- Rotten Egg Smell: Sudden, persistent sulfur or rotten egg odor indoors or near exterior gas lines
- Hissing or Whistling: Unusual sounds near gas appliances or lines, especially at joints or connections
- Dead or Discolored Vegetation: Grass or shrubs dying in a line over a buried pipe, especially if the area is otherwise healthy
- Unexplained Dizziness, Headache, or Nausea: Physical symptoms that appear at home and fade outdoors
- Visible Air Movement: Dust or dirt blowing at a pipe without wind
- Pilot Lights Going Out Repeatedly: Gas appliances shutting off without cause
We often encounter leaks when working on other systems. For example, our leak detection and repair crew might uncover gas issues while handling water leaks or slab repairs. Both can be tied to ground movement or aging infrastructure.
Seasonal Prep and Preventive Steps
Each fall and winter, the stress on gas lines increases. Those cold snaps we see in Elwood can shrink metal pipes, sometimes enough to open up minor gaps that weren't there in warm weather. To cut your risk:
- Have a licensed plumber inspect exposed lines and appliance connections at least once a year
- Check around your water heater, furnace, and stove for any odd odors or sounds
- When doing any digging in the yard, call 811 ahead to have lines marked
- Test gas shutoff valves for proper function (but don't force them if stuck)
- Install carbon monoxide detectors as a backup safety measure
If you're already updating systems, consider having our pipe repair and repiping team look at your gas piping as well as water lines. This is especially important in homes with original galvanized or steel pipes. Gas lines age just like supply pipes and can show signs of corrosion and joint leaks after decades underground.
What To Do If You Suspect a Leak
If you notice any of the warning signs listed above, take it seriously. Here's our advice:
- Don't light matches, use switches, or anything that could create a spark
- Evacuate everyone from the house
- Shut off the main gas supply from outside if you know how to do it safely
- Call your gas utility to report the emergency
- Once clear, contact a professional for safe inspection and repairs

Related Seasonal Concerns
Gas leaks often show up when you turn on your furnace, water heater, or other gas appliances after a long period of disuse. That's why we recommend combining your gas line checkup with water heater services each fall. If you experience issues with musty smells, standing water, or rising humidity in your basement, these can also point to other pipe issues. Our sewer line services team sometimes spots signs of both water and gas problems during inspections, especially in older homes with shifting foundations.
