Signs You May Have a Gas Leak
People often expect a dramatic “movie moment,” but gas leaks can be subtle. Here are common warning signs:
Rotten egg or sulfur-like smell
Utilities add an odorant to help you detect leaks. If you smell it, leave.
Hissing, roaring, or blowing sounds near a line or appliance
Sound can indicate gas escaping under pressure.
Physical symptoms indoors
Headache, dizziness, nausea, or irritation—especially if symptoms improve outdoors—should be taken seriously. (If anyone is in distress, call emergency services.)
Dead vegetation or unusual bubbling outside
Outside leaks may show up as dead/brown patches, dirt blowing, or bubbling in wet areas.
What Not to Do During a Gas Leak
In a suspected gas leak, avoid anything that could ignite the gas:
-
Don’t turn the lights on or off
-
Don’t use candles, lighters, or matches.
-
Don’t use appliances or the garage door opener.
-
Don’t “check it real quick” by staying inside
-
Don’t smoke
-
Don’t try to fix the leak yourself.
Leave and call for help from outside.
Who to Call for a Gas Leak in Charleston, SC
A lot of people hesitate because they’re unsure who owns what part of the system. Here’s a clear way to think about it:
1) If you smell gas indoors: evacuate and call 911 / the gas utility
South Carolina emergency guidance emphasizes getting outside quickly and addressing utilities safely.
2) If the leak is near the meter or outside lines: call the gas utility
Utilities provide emergency response guidance and may dispatch technicians for the utility-owned portions of the system.
3) After the area is safe, call a qualified professional for inspections and repairs
Once the immediate emergency is controlled, the next step is identifying why it happened and what needs repair or replacement to prevent a repeat.

Common Causes of Gas Leaks in the Lowcountry
While every home is different, gas leaks often trace back to a few scenarios:
Aging fittings and corrosion
Over time, connections can loosen, gaskets can wear, and lines can degrade.
Appliance connections and shutoff valves
Ranges, dryers, fireplaces, and water heaters can develop issues at connection points.
Accidental damage from digging or construction
This is a big one—especially with landscaping, fence posts, irrigation work, or remodeling. Dominion Energy’s pipeline safety guidance stresses contacting 811 before you dig to prevent dangerous strikes.
Gas Leak Detection Basics
When everything is safe and professionals are on-site, leak detection may involve a mix of methods:
Visual checks and connection inspection
Technicians may start by inspecting exposed fittings, appliance connectors, and shutoffs.
Instrument-based detection
Gas detection instruments can help pinpoint the source faster than guesswork.
Pressure testing and system isolation
For some systems, testing can confirm whether a leak exists and help narrow down where it’s happening.
The key point: detection should be done by qualified professionals—not trial-and-error in a potentially dangerous environment.
