Gas Repairs Johannesburg covers faults on the installation: regulators, valves, connections, pipework and the pressure problems that make perfectly good appliances behave badly.
Roughly half the calls that start as a broken appliance turn out to be a supply problem. A hob with weak flames on every burner is not four failed burners; it is a regulator, an undersized line or an empty cylinder.
If you can smell gas right now, stop reading. Close the cylinder valve if you can reach it safely, open doors and windows, do not touch light switches or anything that could spark, do not use a phone inside the building, get everyone out, and call your gas supplier's emergency line or the City of Johannesburg Emergency Connect line on 011 375 5911, or 112 from a mobile.
Describe what the appliance is doing and how long it has been doing it.

| Symptom | Common cause | Usual fix |
|---|---|---|
| Weak flame on every burner | Regulator failure, empty cylinder, undersized line | Replace regulator or upsize supply |
| Flame drops when another appliance runs | Line undersized for simultaneous draw | Upsize the run or the cylinder bank |
| Yellow, sooty flames | Wrong jets for LPG, or a blocked burner | Convert jets or clean the burner |
| Smell of gas near the cylinder | Failed seal, loose connection, perished hose | Leak test and repair; treat as urgent |
| Gas runs out far faster than before | Leak, or an appliance running inefficiently | Pressure test the installation |
| Appliance will not stay lit | Flame failure device, thermocouple or pilot fault | Appliance repair |
| Regulator icing up in winter | Excessive draw for the cylinder size | Add cylinder capacity |
| Nothing at all, cylinder not empty | Closed valve, blocked regulator, changeover set wrong | Diagnose on site |

Compare Gas Repair QuotesInstallation Fault or Appliance Fault
A quick way to narrow it down before anyone visits, which makes the call-out shorter and cheaper:
- Does it affect every appliance? Then it is the supply: cylinder, regulator or the main line.
- Does it affect one appliance only? Then it is that appliance, or the branch and valve feeding it.
- Does it affect one burner on one appliance? That is a burner, injector or tap, and an appliance repair.
- Did it start after somebody worked at the property? Say so. A closed valve or a knocked line after a renovation is a five-minute fix that can otherwise take an hour to find.
Appliance-specific faults are covered on Gas Appliance Repairs Johannesburg, and geyser faults, which are the most common of all, on Gas Geyser Repairs Johannesburg.
Emergency and Same-Day Work
Some installers on this network offer after-hours and same-day attendance and others do not, and availability varies by suburb and by season. If your job is urgent, say so in the request: the installers who can attend today will say so, and you will not waste a day waiting on quotes from those who cannot. What nobody should wait for is a suspected active leak, which is an emergency call rather than a quote request.
Do Not Attempt Gas Repairs Yourself
Tightening a fitting, replacing a regulator or swapping a hose on a fixed installation is not a DIY job, regardless of how simple it looks. Beyond the immediate risk, unregistered work voids the installation's certificate and, in most policies, the insurance cover attached to it. Repairs must be done by a registered installer and the installation re-certified afterwards.
Frequently Asked Questions
What does a gas repair cost in Johannesburg?
Call-outs commonly run R450 to R950 and hourly rates R450 to R850 plus parts. A regulator replacement is typically R450 to R1,600 and a leak detection and pressure test R900 to R2,400 excluding any repair.
Why are all my gas burners weak?
A fault affecting every burner is almost always the supply rather than the appliance: a failing regulator, a nearly empty cylinder, or a line that is undersized for what has been added to it. An installer will test the pressure at the appliance to confirm which.
Can a gas leak be repaired, or does the pipework have to be replaced?
Most leaks are at joints, fittings, valves or the regulator and are repaired in place. Line replacement is needed where copper has been physically damaged or corroded through, usually on an exposed external run or where a line was buried without protection, and then normally only for that section.
Do I need a new certificate after a repair?
If the repair alters the installation, yes. Replacing a regulator or a valve, repairing pipework or reconnecting an appliance all mean the installation is re-tested and re-certified. Ask whether the quote includes it.
Can I use my gas while waiting for a repair?
If there is any smell of gas, no. Close the cylinder valve and keep it closed until an installer has attended. For a non-leak fault such as a weak flame or a failed ignition it is usually safe to keep using other appliances, but ask when you book.
Do gas installers work after hours in Johannesburg?
Some do and some do not, and it varies by suburb. Say in your request that the work is urgent and installers who can attend quickly will identify themselves. A suspected active leak should go to an emergency line rather than a quote request.
Repair quotes are arranged through Gas Installers Johannesburg, so you can compare diagnosis, rate and what the recertification costs.
