What are the signs of a gas leak?
Gas leaks announce themselves in more ways than one, and any single one of these deserves a proper check:
- The smell itself: the rotten-egg odourant, near the meter, under the floor or around an appliance
- A faint hiss or whistle where a pipe, hose or flexi connector meets a fitting
- Dead grass or dying garden beds in a line across the yard above a buried run
- Burner flames burning yellow or orange instead of clean blue
- Headaches or dizziness that ease when you step outside while the heater runs

How the leak gets found and fixed
The visit runs in four moves:
- 1
Detector sweep
A handheld gas detector gets walked along every pipe run between the meter and each appliance, following the smell to its source.
- 2
Isolate
The faulty appliance or section of line is shut off and the gas supply isolated at the meter.
- 3
Repair
The failed fitting, hose or pipe section gets replaced; flexi connectors past their life get swapped on the spot.
- 4
Test and sign off
We pressure-test the line, check each burner's flame and complete the compliance paperwork.

What shapes the cost of the repair?
We provide up-front, honest quotes that will always match the final price, should you decide to go ahead.
For a leak, reaching it is usually the biggest cost:
- A loose fitting behind a cooktop is quick to get at, while a buried run has to be located and dug
- What has failed, from a single connector to a section of pipe that needs replacing
- Pressure testing and paperwork, which every repair includes
- After-hours timing, which changes the rate on the call
New gas lines and other gas work come under our gas fitting service.

When we're not the right call
Gas escaping at the meter or in the street is your gas distributor's to fix. An appliance too far gone to repair is covered by gas appliance installation, and hidden water leaks are traced under water leak detection.
Gas leak questions we hear
What should I do if I can smell gas in my Thornton home right now?
Clear the house and leave lights and electrical switches untouched. Once outside, the gas supplier's emergency number is the first call. Once they have made it safe, we repair any leak in your own pipes and appliances.
Can you find a gas leak under the concrete slab of an estate home?
Mostly, yes. Where a gas line runs under concrete, the detector and a pressure test narrow the leak to one section, so concrete only gets cut if the repair itself needs it.
Do the fast-built estate homes have weaker gas fittings?
They can. Volume builds can leave behind fittings that do not last the way they should, and the gas side is no exception. If a newer home keeps losing pressure, checking the fittings behind the appliances is the sensible place to start.
Does a gas leak repair carry the same warranty as other work?
Yes, the 365-day warranty on all work applies to gas repairs too. If a fitting we replaced fails inside the year, ring the same number.
