How do you know if you have a gas leakage?

Gas leaks in your home can be a silent threat, often unnoticed until it’s too late. Don’t ignore these key signs – your safety could be at risk:

  • Distinct sulfur-like odour: For easy detection, gas companies add a strong sulfur or rotten egg smell to natural gas. So, in case of a leak, you should smell it.
  • Hearing unusual hissing sounds: Listen for unusual hissing or whistling sounds near gas lines or appliances.
  • Noticeable air movement: Feel for drafts or air movement in areas with gas lines.
  • Your house plants are dying: Indoor plants wilting or dying unexpectedly can be a subtle sign of a gas leak.
  • Feeling any physical: Be aware of symptoms like dizziness, headaches, or nausea, as these can be caused by gas exposure.
  • Visual signs: Check for visible signs like soot or dusty air movement around appliances and pipes.
  • A spike in your gas bill: An unexplained increase in your gas bill might indicate a hidden gas leak.

If you are experiencing any of the above, do not hesitate! Contact us and rectify critical issues today!

Gas leaks in homes often manifest in physical symptoms caused by decreased oxygen levels. These signs include feeling lightheaded, persistent headaches, eye and throat irritation, nausea, and experiencing nosebleeds. Additionally, individuals might notice a persistent ringing in their ears and difficulty breathing. Pets, too, are susceptible to these effects, showing symptoms like watery eyes, reduced appetite, disorientation, behavioural changes, and, in severe cases, loss of consciousness. Please be aware, and if any of these signs occur, contact an expert immediately.

Be alert for subtle gas leak indicators: unusual hissing sounds near gas lines, a persistent sulfur odour (resembling rotten eggs), and changes in burner flame colour to anything but blue. Visible pipe damage, increased window condensation, and unexpected plant wilting warrant immediate attention. These signs and unusually high gas bills suggest a gas leak, necessitating prompt expert intervention.
