You're making dinner. The burners look fine. But there's a faint smell — almost like rotten eggs — hanging in the air. That smell is not something to ignore. Gas companies add a chemical called mercaptan to natural gas so you can detect a leak. If you're catching that odor, your nose is doing its job.
Knowing the warning signs of a gas leak in your McKinney home could protect your family from a serious emergency. Natural gas is colorless and has no natural smell. The signs are there if you know what to look — and listen — for.
Five warning signs, the right steps for the first five minutes, and knowing when to call a licensed McKinney gas line plumber — that's what you'll find here. The faster you act, the safer your home stays.
A gas leak in your McKinney home can show up in five ways. Watch for a rotten egg or sulfur smell near appliances or gas lines. Listen for a hissing or whistling sound close to your meter or pipes. Check for dead or yellowing plants in an otherwise healthy yard near buried lines. Look at your pilot lights — a yellow or orange flame instead of blue is a warning sign. Pay attention to how you feel. Headaches, nausea, or dizziness that clear up when you go outside can point to gas exposure. For more on gas safety, see the U.S. Consumer Product Safety Commission's guidance. If you notice any of these signs, leave your home immediately. Call 911 from a safe distance. Then call a licensed McKinney gas line plumber at (469) 398-3229.
Natural gas gives off clear signals when something is wrong. Knowing what to look for helps you act fast before a small problem becomes a dangerous one.
1. A Rotten Egg or Sulfur Smell — This is the most common sign. Gas companies add mercaptan to natural gas so leaks have a noticeable odor. Even a faint smell near your stove, water heater, or gas lines is worth taking seriously. Do not wait for the smell to get stronger.
2. A Hissing or Whistling Sound — A hissing sound near your gas meter, appliances, or along your walls can mean gas is escaping from a line. The sound may be soft. If you hear it consistently in the same spot, that's a red flag.
3. Dead or Dying Plants Near Buried Lines — If a patch of grass or plants in your yard is dying for no clear reason, it could be from a gas leak underground. This is more common in McKinney's newer master-planned communities where buried CSST flexible lines run beneath landscaped areas.
4. Pilot Lights That Won't Stay Lit — A pilot light that keeps going out — or burns yellow or orange instead of blue — signals that gas is not burning correctly. This can also increase the risk of carbon monoxide buildup inside your home.
5. Physical Symptoms That Clear Up Outside — Headaches, nausea, or dizziness that go away once you step outside are warning signs of gas exposure. If more than one person in your home feels this way at the same time, leave immediately.
If you notice any of the warning signs above, every second counts. Follow these steps in order.
Step 1: Don't touch any switches — Do not flip light switches, use your phone, or turn any appliances on or off. Even a small spark can ignite leaking gas.
Step 2: Leave immediately — Get everyone out of the house — including pets. Do not stop to grab belongings. Leave doors open as you exit to help ventilate the space.
Step 3: Call 911 from a safe distance — Move well away from your home before making any calls. Use a neighbor's phone if yours is inside. Tell the dispatcher you suspect a gas leak.
Step 4: Call Atmos Energy's emergency line — Atmos Energy serves most of McKinney. Their 24-hour emergency number is 866-322-8667. They will send someone to confirm the leak and shut off your meter if needed.
Step 5: Call a licensed McKinney plumber — Once you are safe and Atmos has been notified, call Baker Brothers at (469) 398-3229. Do not re-enter your home until a professional has cleared it. Our team is available 24/7 for gas line emergencies in McKinney.
Most McKinney homeowners are not sure who to call first during a gas emergency. Here is how the roles break down.
Atmos Energy is your gas utility provider. When you report a leak, they will come out and check your lines. If they find one, they will confirm it and shut off your meter. That is where their job ends. Atmos Energy's responsibility stops at the meter. Everything on your side of the meter — inside your home and on your property — is yours to repair.
Once Atmos shuts off and locks your meter, a Texas-licensed plumber must repair the line, pull a permit with the City of McKinney, and pass a city inspection before your gas can be restored. This process can take several days if the steps are not followed in the right order.
| Atmos Energy | Licensed Plumber |
|---|---|
| Confirms the leak exists | Locates and repairs the line on your property |
| Shuts off and locks the meter | Pulls the required city permit |
| Responds to gas emergencies | Passes city inspection before gas is restored |
| Handles lines up to the meter | Handles all lines past the meter |
Calling Baker Brothers before Atmos locks your meter can save you time. Our licensed McKinney plumbers can walk you through how to shut off your gas safely while we are on the way. We handle the repair, the permit, and the inspection coordination — so your gas is restored as quickly as possible.
McKinney is one of the fastest-growing cities in North Texas. That rapid growth brings specific gas line risks that older, more established areas don't always face.
Newer Construction and CSST Flexible Piping — Many McKinney homes built in the 1990s through 2020s use corrugated stainless steel tubing — known as CSST. The Uniform Plumbing Code requires CSST to be properly bonded and grounded to perform safely. When it is not installed correctly, it can develop leaks from nail punctures or proximity to roof decking.
Tree Preservation Districts — McKinney has active tree preservation requirements in many neighborhoods. Large root systems near gas line easements can shift soil and put pressure on buried lines over time. This is something our team watches for closely during inspections in heavily landscaped areas.
HOA Landscaping Near Gas Easements — Many McKinney HOAs require specific landscaping along easements. Planting too close to buried gas lines can lead to root intrusion or damage during irrigation installation.
New Appliance Hookups — McKinney's growth means a lot of homeowners are adding gas appliances — outdoor kitchens, fire pits, gas dryers, and whole-home generators. Connections that are not handled by a licensed plumber can introduce leak points into an otherwise sound system.
Smart Home and Renovation Work — Remodels are common in McKinney's high-value homes. Untrained contractors working near shared walls or utility spaces can disturb gas fittings without realizing it. Any renovation that touches walls, floors, or utility areas near gas lines warrants a professional inspection afterward.
The best gas emergency is the one that never happens. These steps help McKinney homeowners stay ahead of potential problems.
Schedule Annual Gas Line Inspections — A licensed plumber should inspect your gas lines every one to two years. This includes visual checks of connectors, valves, and flexible lines. McKinney's mix of newer construction and rapid growth makes routine inspections especially worthwhile. Our team at Baker Brothers can assess your full system and flag anything that needs attention.
Install a Methane Detector — A methane or natural gas detector gives you an early warning before gas reaches a dangerous level. Place detectors near the floor, close to gas appliances like your water heater, furnace, and stove. Follow the manufacturer's instructions for placement and testing. These devices work alongside your senses — not instead of them.
Know Where Your Gas Shutoff Is — Every McKinney homeowner should know where their main gas shutoff valve is located before an emergency happens. Walk your property and locate it now. If you are not sure where it is, ask us during your next service visit.
Never DIY Gas Line Connections — Adding a gas grill, fire pit, or outdoor kitchen to your McKinney backyard? Do not connect the gas line yourself. Only a Texas-licensed plumber with gas piping certification can legally and safely make those connections.
Call Us After Any Renovation — If you have recently remodeled your kitchen, bathroom, or any space near gas lines, schedule an inspection before returning to normal use. This is one of the most overlooked steps in McKinney home renovations.
