Recognizing the Signs of a Gas Leak
Natural gas and propane leaks are among the most dangerous situations a homeowner can face. A gas leak can lead to explosions, fires, carbon monoxide poisoning, and serious health problems. Knowing the warning signs can save your life and protect your family. In Cody and across the Big Horn Basin, many homes rely on natural gas or propane for heating, cooking, and hot water, making gas leak awareness essential for every homeowner.
Gas companies add a chemical called mercaptan to natural gas, which gives it a distinctive rotten egg or sulfur smell. This odor is your first line of defense in detecting a gas leak. However, not all leaks produce a detectable smell, especially small leaks behind walls or underground. That is why professional detection with electronic sensors is so important.
Warning Signs Inside Your Home
- Rotten egg or sulfur smell
- Hissing or whistling near gas lines
- Physical symptoms: headaches, dizziness, nausea
- Fatigue or difficulty breathing
- Pilot lights that frequently go out
- Yellow or orange burner flames instead of blue
- Excess condensation on windows near appliances
Warning Signs Outside Your Home
- Dead or dying plants near gas lines
- Bubbling in standing water or puddles
- Dirt blowing from a hole in the ground
- Hissing sounds near outdoor gas meters
- Unusual patches of dead grass in the yard
- Higher-than-normal gas bills
- Visible damage to gas line connections
What to Do If You Suspect a Gas Leak
If you suspect a gas leak in your home, your immediate priority is getting everyone out safely. Gas leaks can escalate from a minor issue to a life-threatening emergency in seconds. Follow these steps to protect yourself and your family:
1. Leave Immediately
Get everyone out of the house, including pets. Do not stop to gather belongings. Move at least 100 feet away from the building. If the smell is strong or you feel dizzy, get out as fast as possible.
2. Do Not Create Sparks
Do not flip any light switches, turn on or off any electrical devices, use your phone, light matches, or start your car in the garage. Even a small spark can ignite accumulated gas and cause an explosion. This includes doorbells, garage door openers, and flashlights.
3. Call From Outside
Once you are safely away from the building, call 911 first, then call Wrangler Plumbing at (307) 587-3713 for emergency gas leak detection and repair. We provide 24/7 emergency response for gas leaks throughout Cody and the Big Horn Basin.
4. Do Not Re-Enter
Do not go back inside for any reason until a professional has inspected the home, found the source of the leak, and confirmed it is safe. Even if the smell seems to fade, gas may still be accumulating in dangerous concentrations inside walls, attics, or crawl spaces.
Our Professional Gas Leak Detection Methods
At Wrangler Plumbing, we use multiple professional-grade detection methods to locate gas leaks accurately, even when they are hidden behind walls, under floors, or buried underground. Relying on smell alone is not enough. Many leaks are too small to detect by odor, and some areas of your home may trap gas in ways that prevent the smell from reaching living spaces.
Electronic Gas Detection
We use commercial-grade electronic gas detectors that can sense even trace amounts of natural gas or propane in the air. These handheld instruments are sensitive enough to pinpoint leaks at individual fittings, connections, and joints throughout your gas line system. Electronic detection allows us to find leaks behind drywall, inside wall cavities, and in other concealed areas without destructive exploration.
Pressure Testing
Pressure testing is one of the most reliable methods for confirming gas line integrity. We isolate your gas line system, pressurize it with air or inert gas, and then monitor the pressure gauge over a set period. Any drop in pressure indicates a leak somewhere in the system. This method detects even very small leaks that electronic sensors might not catch in open areas and is required by code for new gas line installations and repairs in Wyoming.
Soap Bubble Testing
For accessible fittings, connections, and joints, we apply a soap solution directly to the surface. If a leak is present, the escaping gas creates visible bubbles at the exact point of the leak. This simple but effective method provides visual confirmation and precise location of leaks on exposed gas piping.
Why Professional Detection Matters
Many gas leaks occur in locations that are impossible to detect by smell alone: behind finished walls, under concrete slabs, in crawl spaces, and in underground gas supply lines. A professional inspection using electronic sensors and pressure testing is the only way to confirm your gas system is safe. Older homes in Cody and the Big Horn Basin are especially susceptible to hidden leaks due to aging connectors, corroded fittings, and settling foundations that stress gas line joints.
Common Causes of Gas Leaks in Cody Homes
Understanding what causes gas leaks can help you take preventive measures and recognize potential problems before they become dangerous. In the Big Horn Basin, several factors increase the risk of gas leaks in residential properties.
- Corrosion: Gas lines, especially older black iron and galvanized steel pipes, corrode over time. Wyoming's climate, with extreme temperature swings and dry conditions, accelerates corrosion on exterior and underground gas lines.
- Loose fittings and connections: Threaded gas fittings can loosen over time due to vibration, thermal expansion and contraction, and settling of the building structure. Appliance connections are particularly vulnerable.
- Aging flexible connectors: Older flexible gas connectors (especially brass connectors manufactured before the late 1990s) are prone to cracking and failure. These should be inspected and replaced if they show any signs of deterioration.
- Ground settling and shifting: The clay-heavy soils in parts of the Big Horn Basin expand and contract with moisture changes, putting stress on underground gas lines and causing joints to separate.
- Improper installation: Gas lines installed without proper permits, by unlicensed individuals, or using incorrect materials are a common source of leaks. DIY gas line work is especially dangerous.
- Physical damage: Excavation, remodeling, or even hanging pictures on walls can damage gas lines running through walls and underground.
Carbon Monoxide Dangers
Gas leaks are closely related to carbon monoxide (CO) dangers. When gas appliances burn fuel incompletely due to poor ventilation, damaged heat exchangers, or blocked flues, they produce carbon monoxide, a colorless, odorless gas that can be fatal. Every home with gas appliances should have working carbon monoxide detectors on each level. If your CO detector alarms, treat it as seriously as a gas leak: evacuate immediately and call for help.
Older Big Horn Basin Homes at Higher Risk
Homes built before the 1990s in Cody, Powell, Lovell, and other Big Horn Basin communities often have original gas piping that has been in service for 30 to 50 years or more. These aging systems are at significantly higher risk for leaks due to corrosion, outdated connector types, and decades of thermal stress. If your home is more than 25 years old and has not had a gas line inspection, we strongly recommend scheduling a professional evaluation. A proactive inspection is far less expensive than an emergency repair and far safer than an undetected leak.

Gas Leak Detection FAQ
The most common signs include a rotten egg or sulfur smell, a hissing or whistling sound near gas lines or appliances, dead or dying vegetation near gas lines, higher-than-normal gas bills, and physical symptoms like headaches, dizziness, nausea, or fatigue. If you notice any of these signs, leave your home immediately and call (307) 587-3713 from outside.
Leave the house immediately. Do not flip any light switches, use your phone, or create any sparks. Do not start your car in the garage. Once you are safely outside and away from the building, call 911 and then call Wrangler Plumbing at (307) 587-3713 for emergency gas leak detection and repair. Do not re-enter the home until a professional has cleared it.
We use electronic gas detectors that sense trace amounts of natural gas or propane in the air. We also use pressure testing, where we pressurize the gas line and monitor for pressure drops. Soap bubble testing is used on accessible fittings and joints. These methods find leaks behind walls, under floors, and underground without destructive exploration.
Yes. Even a small gas leak is dangerous. Natural gas is highly flammable and can ignite from a spark. Small leaks allow gas to accumulate in enclosed spaces over time, reaching dangerous concentrations. Prolonged exposure can also cause carbon monoxide poisoning, headaches, and other health problems. Every gas leak should be treated as an emergency.
Gas leak detection costs vary depending on the complexity of the inspection and the location of the leak. A basic inspection typically runs $150-$300. Repair costs depend on what is found. We provide upfront pricing before any repair work begins. For emergencies, call (307) 587-3713 and we respond 24/7.
