A gas leak is one of the most serious plumbing emergencies a homeowner can face. Natural gas itself is odorless, but gas suppliers like Atmos Energy, which serves the Fort Worth and Tarrant County area, add a chemical called mercaptan to give it a distinct rotten egg or sulfur smell. That smell is your first warning. Knowing how to recognize a gas leak and respond correctly can protect your home, your family, and your neighbors.
This guide covers everything Fort Worth homeowners need to know: how to detect a gas leak, what to do in the first critical minutes, and when to call a licensed plumber for gas line repair.
Gas Leak Emergency in Fort Worth?
If you smell gas right now, stop reading. Leave the building immediately without touching any light switches, outlets, or electronics. Call 911 and Atmos Energy's 24-hour emergency line at 1-866-322-8667 from a safe distance. Then call Molberg Plumbing at (817) 476-9963 for emergency gas line service.
Signs of a Gas Leak in Your Home
Gas leaks do not always announce themselves loudly. Some are slow and subtle. Here are the most common warning signs across your senses.
What You Smell
A strong or faint odor of rotten eggs or sulfur at any time other than cooking
A persistent chemical or musty smell near gas appliances, the furnace, or along walls where lines run
What You Hear
A hissing or whistling sound near a gas line, appliance, or meter
An unusual rushing sound from inside walls or near the floor
What You See
Bubbles in standing water or wet soil near your home's foundation
Dead or dying houseplants with no other explanation
Visible damage to a gas pipe, connector, or fitting
Dust or debris moving near a gas line when there is no breeze
Physical Symptoms
Unexplained headaches, dizziness, nausea, or fatigue indoors that clear up outside
Chest tightness or shortness of breath in multiple people in the home
If multiple people in your household are experiencing these symptoms simultaneously, treat it as a gas leak emergency.
What to Do the Moment You Suspect a Gas Leak
Speed and calm matter here. Follow these steps in order.
Stop what you are doing immediately. Do not turn lights on or off, use your phone, trigger a garage door opener, or touch any electrical switch or outlet. Even a small spark can ignite accumulated gas.
Leave every door open as you exit each room. This allows for ventilation and can reduce the risk of buildup.
Get everyone out of the building, including pets. Do not go back for belongings.
Move a safe distance from the property, at least to the end of the block.
Call 911 first, then Atmos Energy's emergency line at 1-866-322-8667. Do not re-enter until officials declare it safe.
Once the area has been cleared, call a licensed plumber to inspect and repair the gas line before restoring service.
Is a Small Gas Leak Dangerous?
Yes. A slow or faint gas leak is still a serious risk. Small amounts of natural gas exposure can cause headaches, nausea, and fatigue over time. More critically, even a minor leak creates a gradual buildup of gas in an enclosed space. Natural gas is highly flammable. A spark from a light switch, a phone charger, or even static electricity is enough to ignite accumulated gas and cause a fire or explosion.
Do not wait to see if a small leak gets worse. Report it and have it repaired immediately.
Should You Open Windows During a Gas Leak?
Texas gas companies, including Atmos Energy, advise against stopping to open windows during an active gas leak. The time it takes to open windows increases your exposure and delays evacuation. Your priority is to get out of the building quickly. Opening doors as you leave provides some ventilation without slowing you down.
After the leak has been repaired and officials have cleared the home, you can open all windows and doors to ventilate the space for several hours before re-occupying.
Gas Leak Detectors: What Fort Worth Homeowners Should Know in 2026
Carbon monoxide detectors and natural gas detectors are not the same thing. A standard CO detector will not alert you to a methane or propane leak. For complete protection, Fort Worth homeowners should have a dedicated natural gas detector or a combination unit that detects natural gas, carbon monoxide, and propane.
Modern gas detectors in 2026 offer several upgrades worth considering:
Smart home integration: Detectors that connect to Wi-Fi and send alerts to your phone even when you are away from home
Automatic shutoff capability: Advanced units that connect to your gas line valve and cut off supply when dangerous levels are detected. These must be installed by a licensed plumber per Texas code.
Multi-gas detection: Units that detect natural gas (methane), propane, butane, and carbon monoxide from a single device
Voice alerts: Devices that announce the type of gas detected, making it easier to respond correctly
Install your detector between 1 and 4 meters from gas-fired appliances. Keep it away from stoves, extractor fans, vents, and sinks, which can trigger false readings.
When to Call a Plumber for Gas Line Service
Fort Worth homeowners should call a licensed plumber any time they suspect a gas issue, even after the immediate emergency has been handled. A plumber can pinpoint the exact location of a leak, assess the condition of your gas lines, and make code-compliant repairs before service is restored.
Common gas line situations that require professional service:
After any confirmed gas leak, before turning gas back on
Aging or corroded gas pipes in older Fort Worth homes
New appliance installations that require gas line connections
Remodeling projects that involve moving or extending gas lines
Recurring pilot light issues or appliances not receiving adequate gas pressure
