Comprehensive Gas Line Repairs

A damaged or leaking gas line poses a serious safety hazard. Issues can arise from corrosion, faulty installation, shifting ground, tree root intrusion, or accidental damage from excavation work. Recognizing the early warning signs of a gas leak can prevent potential dangers, including fires, explosions, or carbon monoxide exposure.

Signs You May Have a Gas Leak:

  • Distinctive Rotten Egg Smell - Gas suppliers add an odorant called mercaptan to help detect leaks. If you notice a sulfur-like smell, it’s a strong indication of a leak.
  • Hissing Sounds- Unusual hissing or whistling noises near gas lines or appliances suggest a pressurized leak.
  • Dead Vegetation - If grass, shrubs, or plants near your gas line suddenly die or discolor, a hidden gas leak could be depriving them of oxygen.
  • Unexplained Increase in Gas Bills - If your gas usage spikes without a corresponding change in appliance use, there may be an undetected leak.
  • Physical Symptoms - Exposure to leaking gas can cause dizziness, nausea, headaches, or even respiratory issues. If multiple occupants experience these symptoms, evacuate immediately.
