A gas leak is one of the most serious issues a homeowner can face. Natural gas is used safely in millions of homes every day, but if it leaks, it can pose a major risk to your health and safety. Knowing how to spot the warning signs early can protect your family — and your property — from harm.
At HomeGuard Heating Solutions, we specialise in gas line inspections, gas leak detection, and repairs. Here’s what you need to know.
Common Signs of a Gas Leak
Gas leaks aren’t always easy to spot, but there are several telltale warning signs to watch for:
a. The Smell of Rotten Eggs
Natural gas is odourless, but utility companies add a chemical called mercaptan to give it a distinct “rotten egg” or sulphur-like smell.
If you notice this odour — especially near your stove, furnace, or gas meter — treat it as an emergency.
b. Hissing or Whistling Sounds
A hissing or whistling noise coming from a gas line, pipe connection, or appliance could mean gas is escaping. Don’t try to find the exact source — leave the area and call for help.
c. Dead or Dying Plants
If you notice patches of dead grass or plants near your gas line or meter, it may be due to gas leaking underground and suffocating the roots.
d. Physical Symptoms
Exposure to leaking gas can cause:
- Headaches
- Dizziness
- Nausea
- Fatigue
- Trouble breathing
If these symptoms improve when you leave your home, it’s a strong indication of a gas leak.
e. Increased Gas Bills
A sudden spike in your gas bill with no clear reason (like colder weather or higher usage) could mean gas is escaping somewhere in your system.
We cover Polperro, Looe, Fowey, Liskeard, Bodmin, Lostwithiel and all surrounding areas — providing quick, reliable repairs to keep your home safe and warm.
