Gas leaks alarm homeowners for good reason. Natural gas and propane are flammable, odorless in pure form, and can cause fires, explosions, or carbon monoxide buildup. Knowing the warning signs and acting quickly makes the difference between a safe repair and serious damage. This guide explains how to respond to a suspected leak, what symptoms mean, and how licensed gas line services in Baton Rouge handle detection, repair, and safety checks.
Recognizing gas leak warning signs
The first clue is often smell. Utility companies add mercaptan, which gives gas a sulfur or rotten-egg odor. You may also hear a hiss or whistle near a line, meter, or appliance. Indoors, headaches, dizziness, or nausea without clear cause can point to gas buildup. Outside, look for dying patches of grass, bubbles in puddles, or soil movement near buried lines. These all suggest a leak that needs immediate attention.
Carbon monoxide is different. It has no odor and forms when gas burns incompletely. Every Baton Rouge home with gas appliances should have working CO alarms on each floor and near sleeping areas.
What to do if you suspect a gas leak
- Leave the building immediately and leave doors open to vent air.
- Do not flip switches, light matches, or use phones inside.
- Call 911 or your gas utility emergency line from outside the home.
- Once the utility has shut off service, contact a licensed plumber for repair.
- Keep everyone away until professionals confirm safety.
Never attempt to tighten fittings, seal a pipe, or turn the gas back on yourself.
How professionals find and fix leaks
Licensed technicians follow a clear process. First, they inspect visible piping, connectors, and appliance valves. They then pressure-test the system with air or inert gas, watching for pressure drops that reveal leaks. Electronic detectors and soap-solution tests pinpoint the source. For underground lines, tracer gas and sensors locate leaks without digging the entire yard.
Repairs depend on what failed. Minor leaks at joints may only need resealing. Damaged connectors or corroded runs are replaced. Afterward, the system undergoes a full pressure test to confirm safety. Every appliance is re-lit, and burners are checked for steady blue flames and proper venting.
Typical causes in Baton Rouge homes
Age, movement, and moisture cause most leaks. Older black iron pipe corrodes at hangers or joints, especially in humid crawlspaces. CSST (corrugated stainless steel tubing) can be damaged by lightning if not properly bonded. Outdoor lines to grills or generators may crack where they exit the ground. In remodels, unpermitted reroutes or mismatched fittings often lead to future leaks.
Why professional gas work matters
Gas piping follows strict local codes for good reason. Baton Rouge and surrounding parishes use the International Fuel Gas Code with local amendments. Work on gas systems—including new lines, extensions, or full replacements—requires licensed professionals and usually a permit. Emergency fixes can be done first for safety, followed by inspection. A qualified contractor coordinates with parish inspectors and the utility to restore service safely.
Cost and repair options
Small leaks, such as a bad connector, can be repaired for a few hundred dollars. Larger jobs involving buried or long interior lines cost more, especially if drywall or floors must be opened. When lines are corroded or repeatedly leaking, replacement or rerouting is often the smarter long-term move. A good contractor explains both options, including timelines, permits, and inspection steps.
Preventive safety tips
- Inspect visible gas lines and connectors yearly, especially in older homes.
- Keep space behind appliances clear to prevent pinched hoses.
- Ensure CSST systems are properly bonded against lightning strikes.
- Install carbon monoxide alarms on every level of the home.
- Plan ahead before remodeling or adding gas appliances to ensure proper sizing and layout.
