The most critical sign is the distinct odor of rotten eggs (Mercaptan), which is added to naturally odorless natural gas for safety. You might also hear a hissing or whistling sound near a gas appliance or gas line, or see unusual symptoms like dead plants near an underground line. If you notice any of these, immediately evacuate the home and call for emergency services.
The absolute first call, from a safe distance outside the building, should be to 911 and your natural gas utility provider (like Atmos Energy or Texas Gas Service in Texas) to report the emergency. After the utility company has turned off the gas supply and declared the area safe, you would call a licensed gas line repair company, like Intown Plumbing, for the necessary expert repairs.
The average cost to fix a gas leak in a home typically ranges from $150 to over $1,000, depending heavily on the leak’s location, severity, and the complexity of the repair. Minor fixes to appliance lines can be inexpensive, but major gas line replacements or leaks inside walls or slabs will increase the cost.
If you call your natural gas utility company (like Atmos Energy) to investigate a suspected gas leak, they typically send a technician immediately to check the area at no charge. However, a licensed private emergency plumber like Intown Plumbing will charge a service or diagnostic fee to locate the leak and provide the necessary gas line repair estimate.
The most common causes include aging infrastructure or corrosion in old gas lines, improper connection or faulty seals on a gas appliance like a water heater or stove, or physical damage to the gas line from digging or home renovations. Over time, components simply wear out, leading to small cracks or breaks that allow leaking gas to escape.
Smelling gas outside your home is a serious warning sign that requires immediate attention, as it could indicate a break in an underground main line or service line leading to your home. It can also sometimes be the result of a small amount of natural gas being safely vented by a meter regulator, especially on cold, still mornings. Regardless of the potential cause, you must treat it as an emergency and call 911 from a safe location.
