A gas leak is one of the most dangerous situations a homeowner can face. Whether you live in Plano, McKinney, Allen, Wylie, Murphy, Frisco, Garland, or anywhere in North Dallas, knowing the signs, risks, and emergency steps can protect your home and your family. Natural gas is safe when installed and maintained properly — but when a leak occurs, every second matters.
This guide explains how to recognize gas leaks, what to do immediately, how professionals find them, and when repairs or replacement are necessary.
Why Gas Leaks Are So Dangerous
Natural gas becomes extremely hazardous when it escapes from a closed system. A leak can cause:
Fires and explosions
Carbon monoxide exposure
Respiratory symptoms
Immediate safety risks for children, seniors, and pets
Because North Texas homes rely heavily on gas appliances and heating systems, even a small leak can quickly escalate into a life-threatening emergency.
Common Signs of a Gas Leak in Your Home
If you notice any of the following, act quickly:
1. Rotten Egg Smell
Natural gas is odorless, but utility companies add a sulfur-like smell to detect leaks easily.
2. Hissing or Whistling Sounds
Gas escaping from a pipe, joint, or flexible connector often creates a faint or strong hiss.
3. Dead Spots in Grass or Landscaping
Underground leaks can kill vegetation directly above the damaged line.
4. Bubbles in Standing Water
If water in your yard bubbles for no reason, gas may be escaping below.
5. Sudden Health Symptoms
Gas exposure can cause:
Headaches
Dizziness
Fatigue
Nausea
Difficulty breathing
If symptoms improve when you go outside, suspect a gas issue.
6. Unexplained Increase in Gas Bills
Higher usage with no change in habits often indicates a hidden leak.
Immediate Steps to Take If You Suspect a Gas Leak
If you think a leak is present:
1. Leave Immediately
Get everyone — including pets — outside and away from the home.
2. Avoid Electrical Switches
Do not turn lights, appliances, or garage doors on or off.
3. Do NOT use your phone inside the house
Any spark can ignite accumulated gas.
4. If safe, turn off gas at the meter
Most homes have an exterior shutoff valve that can be turned using a wrench.
5. Call Atmos Energy
Emergency Line 866-322-8667
They will dispatch technicians to secure the area.
6. Contact a licensed plumber to repair the leak
Atmos will not perform repairs — they only make the site safe. A licensed plumber must locate the leak, fix it, and perform the pressure test before service is restored.
How Professionals Detect Gas Leaks
MRC Plumbing Solutions uses specialized equipment to locate leaks safely and precisely:
Electronic gas detectors
Whole-home pressure testing
Soap testing for fittings
Underground line tracing
This ensures every leak — visible or hidden — is found and corrected.
Common Causes of Gas Leaks in North Texas Homes
Aging or Corroded Gas Lines
Older homes may have galvanized or black steel lines that corrode over time, especially in humid or shifting soil conditions.
Foundation Shifting
North Texas clay soil expands and contracts dramatically, causing pipe joints to loosen or crack.
Damaged Flexible Connectors
Kinked, crushed, or outdated connectors frequently cause leaks, especially behind appliances.
Outdoor Line Damage
Tree roots, irrigation installation, digging, or fence work can rupture buried gas lines.
When Does a Gas Line Need Repair vs. Replacement?
Repair is typically appropriate when:
The leak is isolated to a single fitting
The line is newer and in good condition
A single section of pipe is damaged
Replacement is recommended when:
The home has outdated galvanized or rusted steel lines
Multiple leaks appear throughout the system
Foundation movement has compromised an entire run of pipe
Lines fail pressure testing even after repairs
Replacing old or damaged gas lines dramatically improves long-term safety.
What to Expect During Gas Line Repairs
When MRC Plumbing Solutions performs a repair, you can expect:
A full system pressure test
Leak detection with modern tools
Permanent, code-compliant repairs
Coordination with Atmos Energy for gas restoration
Transparent pricing and clear communication
Your safety is our priority.
How to Prevent Future Gas Leaks
Schedule annual gas safety inspections
Replace old or damaged flexible connectors
Monitor monthly gas usage for unexplained increases
Know where your main shutoff valve is located
Keep vegetation, irrigation, and digging activities away from marked gas lines
