Key Takeaways
- If you smell gas in your Mesquite home, leave immediately and call 911 plus Atmos Energy (866-322-8667) from a safe distance. Do not flip switches, use your phone inside, or touch any gas valve.
- Gas line work — installation, repair, and maintenance — is a licensed-plumber job in Texas. The risks of a bad install (fire, explosion, carbon monoxide leak) make this one of the most regulated areas in residential plumbing.
- The gas piping from your Atmos meter into your home is your responsibility, not the utility’s. Atmos maintains up to the meter; everything past it falls to the property owner.
- A yearly professional inspection is the simplest preventive step. A licensed plumber pressure-tests the lines, checks connections, and confirms appliances vent safely.

What should you do if you smell gas in your Mesquite home?
If you smell a sulfur or rotten-egg odor inside or outside your home, leave immediately, then from a safe distance call 911 and Atmos Energy’s 24-hour emergency line at 866-322-8667. Atmos Energy is the natural gas utility for Mesquite and the surrounding DFW area, and they will dispatch a technician at no cost to investigate.
This is the most important safety information on this page. Treat any gas smell as a real leak until a professional confirms otherwise.
Atmos Energy’s official guidance is clear: leave the premises immediately, then call 911 and 866-322-8667 from a safe distance. Do not rely on your sense of smell alone — also listen for hissing near appliances and look for blowing dust, bubbling water, or dead plants near gas lines outside.
While you’re leaving, do not:
- Flip light switches, plug or unplug anything, or use any appliance
- Use a phone, garage door opener, or anything that can spark — wait until you’re outside
- Start a vehicle, light a match, or operate a flashlight with a switch
- Try to find the leak yourself
- Turn the gas main on or off (you may make it worse, and you’ll be standing next to a live leak to do it)
Once you’re a safe distance away and emergency services are on the way, the next call is a licensed plumber to repair the line after Atmos clears the home.
Why is gas line work a licensed plumber’s job, not a DIY project?
Gas line installation, repair, and maintenance are licensed-plumber work in Texas because the consequences of a mistake are severe — fire, explosion, or carbon monoxide poisoning. State law and local code require licensed work for gas piping, and most insurance policies require the same.
There are three specific risks DIY work creates:
Leak risk. A connection that looks tight to the eye can still leak. Licensed plumbers pressure-test every joint and confirm it holds before turning gas back on.
Carbon monoxide risk. Gas appliances need proper combustion air and venting. An undersized or wrongly routed line starves the appliance, which can produce carbon monoxide instead of clean combustion.
Code and warranty risk. Texas requires permits and inspections for many gas line jobs. DIY work voids appliance warranties and creates liability if you ever sell the home or file an insurance claim.
This is also why Atmos Energy itself directs customers to licensed plumbers and certified contractors for any work on the gas piping past the meter.
Who’s responsible for the gas line — Atmos or the homeowner?
Atmos Energy is responsible for the natural gas line up to the gas meter on your property. The piping from the meter into your home, and all the lines connecting to your appliances, are the homeowner’s responsibility — the same way you own your electrical wiring past the panel.
Atmos states this explicitly: in Texas, the property owner is responsible for the natural gas piping from the meter to the home or business. That means inspections, leak repairs, line extensions for new appliances, and pipe replacement on your side of the meter are all your responsibility — and need to be done by a licensed plumber.
Knowing this matters when you call about a problem. If the issue is past the meter, Atmos will shut off the gas safely but will not repair the line — that part is on you.
What does gas line maintenance actually look like?
For homeowners, gas line maintenance is mostly observation and one yearly professional visit. The lines themselves are designed to last decades when undisturbed, and most leaks come from age, ground movement, or work done on or near the line.
What homeowners can safely watch for:
- A rotten-egg or sulfur smell anywhere in the home (treat as a leak — see safety steps above)
- A hissing sound near a gas appliance or meter
- Dead patches of grass in a line that traces from the meter to the home
- A pilot light that won’t stay lit, or a stove that burns yellow/orange instead of blue
- Higher gas bills with no change in usage
What a licensed plumber does on an annual inspection:
- Pressure-tests the gas piping to verify there are no leaks
- Checks each appliance connection and shut-off valve
- Confirms gas appliances are venting properly (a combustion-air and carbon-monoxide check)
- Inspects the line for corrosion, damage, or undersized runs
- Documents the inspection for insurance and resale records
In Mesquite specifically, the same expansive clay soil that cracks sewer pipes can stress buried gas lines as the ground shifts seasonally. A yearly inspection catches problems before they become emergencies.
When should you call a plumber instead of waiting?
Call a licensed plumber any time you’re adding, moving, or removing a gas appliance, smell gas (after you’ve left the home and called 911), or notice any of the warning signs above. Don’t wait for a yearly inspection if something feels off — gas problems do not improve on their own.
Specific situations that always need a plumber:
- Installing a new gas range, dryer, water heater, or outdoor grill on a permanent line
- Moving an existing appliance to a new location
- Replacing an old line, especially in homes 30+ years old
- After any foundation work, trenching, or landscaping near the gas line
- After a freeze, flood, or storm that may have damaged buried piping
- Any time you suspect a leak that’s been confirmed safe by Atmos but still needs the line repaired
