Natural gas keeps your Fulshear home comfortable — powering your furnace, water heater, stove, and more. But when a gas line develops a problem, that same convenience becomes a serious safety hazard. Gas leaks can go undetected for hours or even days, putting your family at risk of fire, explosion, or carbon monoxide poisoning.
Knowing the warning signs of a gas leak can save your life. Below are five telltale signs that something may be wrong with your gas lines — and exactly what to do if you spot them. If you suspect a leak right now, leave your home immediately and call 911, then call Katy Plumbing at (281) 601-1513.
1. You Smell Rotten Eggs or Sulfur
Natural gas is odorless in its natural state, so utility companies add a chemical called mercaptan to give it a distinctive smell — often described as rotten eggs or sulfur. If you notice this odor anywhere in your home, especially near appliances, utility rooms, or along exterior walls, treat it as a gas leak until proven otherwise.
Don’t dismiss the smell as “just the drains” or a temporary odor. Even a faint, intermittent sulfur smell deserves investigation by a licensed gas line professional. The stronger the smell, the more urgent the situation.
2. You Hear a Hissing or Whistling Sound Near Gas Lines
A hissing, whistling, or blowing sound coming from near your gas meter, gas appliances, or the walls/floors where gas lines run is a serious red flag. This sound indicates that gas is actively escaping from a pipe or connection under pressure.
Even if you don’t smell anything yet, a hissing sound near any gas-connected fixture warrants immediate action. Do not attempt to locate or fix the source yourself — leave that to a licensed gas line repair specialist.
3. You Notice Dead or Dying Vegetation in Unusual Patches
This sign is easy to overlook because it happens outside your home. If you have a section of yard, garden, or landscaping where plants are inexplicably dying in a distinct patch — especially in an otherwise healthy lawn — an underground gas line leak could be the cause.
Leaking natural gas displaces oxygen in the soil, essentially suffocating plant roots. You might also notice bubbling in standing water or wet soil, or dirt that appears to be moving or disturbed with no obvious cause. In Fulshear’s newer residential developments, underground gas lines run throughout subdivisions and are especially prone to ground-movement stress as soil settles.
4. Your Gas Bills Spike Without Explanation
A sudden, unexplained increase in your monthly gas bill — without a corresponding change in usage habits or weather — can indicate a slow leak somewhere in your system. Gas is constantly escaping, your meter keeps running, and your bill climbs.
Compare your bill to the same period last year and look for anomalies. If your usage appears to have increased dramatically but nothing in your home has changed, it’s worth having your gas lines inspected. A professional pressure test can quickly identify whether a leak is present.
5. You or Your Family Experience Physical Symptoms
Natural gas leaks can cause a range of physical symptoms, particularly when a leak is occurring in an enclosed space. Watch for:
- Headaches, dizziness, or lightheadedness that improve when you leave the house
- Nausea or vomiting without a clear cause
- Fatigue, confusion, or difficulty concentrating
- Eye or throat irritation
- Pale or blistered skin (in cases of direct gas contact)
These symptoms often worsen in rooms closest to the leak and improve when you spend time outdoors. If multiple family members — or your pets — are experiencing similar symptoms with no other explanation, evacuate your home immediately and seek fresh air. Then call for emergency gas line service.
What to Do If You Suspect a Gas Leak
Time matters. If you notice any of the warning signs above, follow these steps immediately:
- Don’t use any electrical switches, appliances, or your phone inside the home. Even turning on a light can create a spark.
- Don’t try to find or fix the leak yourself.
- Leave the building immediately — take your family and pets and go outside.
- Leave the door open behind you to help ventilate the space.
- Call 911 once you are safely outside.
- Call your gas company (CenterPoint Energy: 888-876-5786) to shut off service.
- Do not re-enter the building until emergency personnel have cleared it.
After the immediate emergency is resolved, you’ll need a licensed plumber to inspect, locate, and repair the damaged gas line before your service can be safely restored.
