Rotten Egg or Sulfur Smell
Natural gas is odourless, but utility companies add a chemical called mercaptan to give it a strong, distinctive smell—similar to rotten eggs—to help detect leaks easily.
Hissing or Whistling Sounds
If you hear a hissing or whistling noise near your gas lines, it could mean gas is escaping from a crack or hole in the line.
Dead or Dying Vegetation
Unexplained plant death or discolored patches of grass near gas pipelines could indicate a leak beneath the surface.
Sudden Increase in Gas Bills
If your gas usage hasn’t changed but your bill has spiked, a leak might be wasting gas and money.
Physical Symptoms Indoors
Gas leaks can affect your health. If you or others in your home experience headaches, dizziness, nausea, or fatigue, especially when inside, it could be a sign of gas exposure.
Malfunctioning Gas Appliances
Gas stoves, heaters, or hot water systems not working properly or with a weak flame may be warning you of a problem with your gas supply.
