The short answer
Why a Gas Leak May Be Hard to Detect
After a fire, the air is full of smoke, soot, and burnt materials. These strong odors can easily hide the distinctive rotten egg smell that gas companies add to natural gas. Your nose may be overwhelmed, making it hard to tell if gas is present.
Even if you do not smell gas, a leak can still exist. Fire can melt or crack pipes, loosen fittings, or damage the meter, sometimes in ways that are not obvious. Relying only on your sense of smell is not enough after a fire.
Immediate Safety Steps to Take
If you smell gas or suspect a leak, do not turn on lights, use a phone, or operate any electrical switch. These actions can create a spark. Leave the house right away and move to a safe outdoor spot.
Once you are safely away, call your gas utility company to report the leak. They can shut off the gas and inspect the lines. Do not attempt to shut off the gas yourself unless you know exactly how and it is safe to do so.
What the Pros Look For
The pros who handle fire cleanup check for secondary issues like gas line damage. They look for melted pipes, scorched fittings, and signs of a leak, but they do not repair gas lines. That work belongs to your gas utility or a qualified plumber.
Their main job is to dry out your home and clean up soot and water from firefighting efforts. If they find a possible gas issue, they will tell you to contact the utility before any cleanup continues. Safety comes first.
Signs of a Gas Leak Beyond Smell
Besides the rotten egg odor, look for a hissing sound near gas appliances or pipes, dead plants in a specific spot, or a white cloud or mist near a line. You might also feel dizzy, nauseous, or have a headache, which can be early signs of gas exposure.
If you notice any of these, treat it as a leak and leave the area. Even a small leak can be dangerous, especially in a home already weakened by fire. Do not wait for a smell to confirm it.
After the Gas Is Turned Off
Once the gas utility shuts off your gas, the line stays off until a qualified professional inspects and repairs it. That inspection is not part of typical water damage cleanup. You will need to coordinate with your utility and possibly a plumber.
The pros can then focus on drying out your home and preventing further issues like mold. If your home has fire and water damage, you may need both services. Check your policy to see what is covered. Policies vary, and your insurer decides what is covered.
Bullets
Leave the house immediately if you suspect a leak.
Do not flip any switches or light matches.
Call your gas utility from outside.
Avoid using the phone inside the home.
Do not try to shut off gas unless trained.
Why You Need a Professional Inspection
Even if you smell nothing, fire can weaken gas lines in ways that only appear later. A professional inspection by your gas utility or a plumber can catch problems before they become dangerous. This is not a job for DIY.
Your local water damage pros can help with the aftermath, but they are not gas experts. They will recommend the right type of qualified professional for gas issues. In Fresno, keep your gas shutoff valve location written down so you can act quickly if needed.

What does a gas leak smell like?
Natural gas itself has no smell, but gas companies add a chemical that smells like rotten eggs or sulfur. This is to help you detect leaks. If you smell that odor, treat it as a gas leak and leave immediately.
Can fire damage cause a gas leak?
Yes, fire can damage gas lines, meters, or valves, leading to a leak. The heat can melt or crack pipes, and falling debris can break fittings. Even if you do not smell gas, have a professional inspect the system.
Who do I call for a gas leak after a fire?
Call your gas utility company first. They can shut off the gas and inspect the lines. Do not try to fix it yourself. After the gas is off, you may need a plumber for repairs, and water damage pros for cleanup.
