Gas Leak Detection & Repairs
Suspect a gas leak? Cylinder running out faster than usual? We provide professional gas leak detection, repairs, and safety inspections across Johannesburg.
What To Do If You Smell Gas
If you suspect a gas leak, follow these simple steps to make the area safe.
Close the Gas Supply
Turn off the valve on your gas cylinder (clockwise to close). If you have an isolation valve, close that too.
Ventilate the Area
Open all windows and doors to allow fresh air in and let the gas disperse naturally.
Avoid Sparks
Don't flip light switches, use appliances, or light matches. If the leak is near your garage, avoid starting your car.
Contact Us
Once the area is ventilated, give us a call to arrange a leak detection and repair.

Gas leaks aren't always obvious. Know these warning signs to protect your family.
Rotten Egg Smell
LP Gas has a strong sulphur/rotten egg odour added for detection. Even a faint smell warrants investigation.
Hissing Sound
A hissing or whistling noise near gas lines, connections, or cylinders indicates escaping gas.
Cylinder Empties Fast
If your gas runs out much quicker than usual, you likely have a leak somewhere in the system.
Yellow or Orange Flame
Gas flames should burn blue. Yellow/orange flames suggest incomplete combustion or contamination.
Dead Plants
Plants dying near buried gas lines can indicate an underground leak.
Physical Symptoms
Headaches, dizziness, nausea, or fatigue when indoors could signal a gas leak.

Gas Leak FAQs
How do I know if I have a gas leak?
The most common sign is a rotten egg smell (mercaptan is added to LP gas for detection). Other signs include hissing sounds near gas lines, your cylinder emptying faster than normal, yellow flames instead of blue, or physical symptoms like headaches and dizziness indoors.
Is a small gas leak dangerous?
Yes. Even small leaks are dangerous. Gas accumulates in enclosed spaces and can reach explosive concentrations. Small leaks also become big leaks over time. Any suspected leak should be investigated immediately by a professional.
How much does gas leak repair cost?
Costs vary depending on the leak location and repair needed. Simple connection repairs start from R500. Pipe repairs or replacements range from R800-R2,500+. We provide upfront quotes before any work begins. Emergency callout fees may apply.
Why is my gas cylinder emptying so fast?
If your gas usage has suddenly increased without explanation, you likely have a leak. Common culprits include worn hoses, loose connections, faulty regulators, or leaks at appliance connections. Call us for leak detection.
Can I use soapy water to find a gas leak?
Soapy water can detect some leaks (bubbles form where gas escapes), but it won't find all leaks, especially small ones or those in hidden locations. Professional leak detection equipment is more thorough and accurate.
Do you provide emergency gas leak services?
Yes, we offer emergency callout services for gas leaks. Gas leaks are safety emergencies and we prioritise these calls. Contact us immediately if you suspect a leak.
Will I get a COC after the repair?
Yes. Every gas leak repair includes a full system pressure test and Certificate of Compliance (COC). This is required by law and essential for your insurance coverage.
How can I prevent gas leaks?
Regular maintenance is key. Have your gas system inspected annually, replace rubber hoses every 2-3 years, ensure proper ventilation, and only use registered gas installers for any work. Never ignore warning signs.
