Of all the leaks a home can have, gas leaks are the only ones that pose a direct safety threat to the people inside. A water leak damages property. A gas leak can ignite, cause carbon monoxide exposure, or in extreme cases lead to explosions. The good news is that natural gas is intentionally odorized so leaks are usually detectable by smell. The bad news is that some gas leaks are too small or too hidden to smell, and these are the ones that need professional detection. Here is how gas leak detection works in NWA homes, when it is needed, and what to do if you suspect one.
Smell gas anywhere in your home? Leave the property immediately and call Bearnwa at 479-321-1313 from outside or your gas utility. Gas leak detection is part of our complete Leak Detection Services lineup.
When Gas Leak Detection Is Needed
You smell gas. Even faintly. The rotten egg smell from natural gas additive is detectable in tiny concentrations. If you smell it, something is leaking. See what to do if you smell gas in your home.
Gas bill suddenly higher. A 15 to 30 percent unexplained increase often indicates a leak somewhere in the supply system or at an appliance.
Dead vegetation near gas lines. Patches of dead grass or plants along the path of buried gas lines can indicate underground leaks.
Hissing sound near gas appliances or lines. Audible hissing from any gas connection point is reason for immediate detection.
Symptoms in occupants. Headaches, dizziness, nausea, or fatigue that improves when away from home and worsens at home can indicate low level gas exposure.
Pilot light keeps going out. Repeated pilot failure sometimes traces to gas pressure or supply issues.
After major renovations or earthquakes. Construction work or ground movement can stress gas connections.
How Gas Leak Detection Works
Professional gas leak detection uses several methods depending on the location and severity.
Combustible gas detectors. Hand held instruments that detect methane and other combustible gases at concentrations far below smell threshold. The detector indicates by audio tone and digital reading.
Soap solution testing. The classic method. A soap solution applied to connections shows bubbles where gas escapes. Simple, reliable, and works for accessible joints.
Electronic methane detectors. Specialized instruments for natural gas (methane) at higher sensitivity than general combustible detectors.
Tracer gas for buried lines. Similar to water leak detection. Hydrogen tracer gas is introduced into the gas line at low pressure. Surface detectors pinpoint exact leak location even through several feet of soil.
Pressure testing. The gas system is pressurized with air and monitored for pressure loss. Standard procedure after any gas system work and useful for system wide leak detection.

What We Detect
Supply line leaks. Connections at the meter, at appliance shutoffs, and at appliance connections themselves.
Appliance leaks. Water heaters, furnaces, ranges, dryers, fireplaces, pool heaters. Any gas appliance has multiple potential leak points.
Buried line leaks. The gas service from meter to house, or yard gas lines for fire pits, pool heaters, or outdoor kitchens.
Pressure regulator leaks. Both at the meter and at appliances with secondary regulators.
Safety Protocols During Detection
Gas work has different safety profile than water work. Standard practices we follow.
No ignition sources. No open flames, sparking equipment, or items that could cause arcing in detection areas.
Ventilation when needed. If concentrations are significant, we ventilate the property before any other work.
Coordination with the gas utility. For supply side leaks or significant concentrations, the utility is notified for their part of the response.
Disconnect affected appliances when warranted. If a specific appliance is leaking, we shut it down at the gas supply before repair work.
Documentation. Detection results are documented for utility, insurance, and homeowner records.
Detection Cost in NWA
| Service | Typical cost |
|---|---|
| Standard gas leak detection visit | $185 to $385 |
| Whole house pressure test | $245 to $445 |
| Buried gas line detection with tracer gas | $385 to $585 |
| Detection plus minor repair | $385 to $785 |
| Emergency response (after hours) | Add $150 to $250 |
Gas vs Carbon Monoxide
Important distinction. Natural gas leaks and carbon monoxide poisoning are different problems requiring different responses. See carbon monoxide vs gas leak understanding the difference for the full breakdown.
Frequently Asked Questions
Can I detect gas leaks myself with home detectors?
Consumer detectors help but they are less sensitive than professional equipment. Useful as early warning. Not a replacement for professional detection.
Will the gas utility do detection for free?
For suspected leaks on their side of the meter, often yes. For appliance and home side leaks, usually they only check for the immediate hazard, not full detection.
How long does professional detection take?
Typically 60 to 120 minutes for residential properties.
Should I leave the house during detection?
Not normally required. If significant concentrations are found, we may ask occupants to leave during certain phases of work.
