Completed repairs are covered on the parts and workmanship for the specific repair we did.
Send us the make, model and what it's doing. We'll tell you the likely next step before booking a visit.
Whether you have a portable generator that can be assessed at our workshop or a fixed standby generator that needs attention at your property, we provide practical repair options for residential and commercial generator systems.

Routine maintenance can help improve reliability, reduce unexpected faults and identify wear before it becomes a more expensive generator repair.
Exercise generators that are not used frequently according to the manufacturer's recommendations so the engine, battery and operating systems remain active.
Inspect engine oil and coolant where applicable, and service or replace fluids according to the maintenance schedule for your generator model.
Old or contaminated fuel can contribute to starting and running problems. Store fuel correctly and follow the manufacturer's guidance for long periods of non-use.
Dirty air, oil and fuel filters can restrict performance. Replace service filters at the recommended intervals for your specific generator.
Routine inspection can help identify worn belts, weak batteries, leaks and developing mechanical faults before they result in a generator breakdown.

No confusing repair process. We inspect the generator, explain the fault and cost, complete the approved work, and test the unit before the job is finished.
Arrange an on-site visit or workshop assessment. The generator is inspected and the reported fault is diagnosed before repair work is recommended.
We explain the recommended repair and provide the repair cost. Work proceeds once the quotation has been accepted.
The approved repair is completed using suitable replacement parts where required. The generator is then tested to confirm correct operation.
Once the repair is completed, qualifying completed work is covered by our 6-month parts and workmanship guarantee.
Our mobile generator repair technicians cover Johannesburg, Centurion and surrounding Gauteng areas for residential, commercial and standby generator repairs.
Johannesburg and Centurion are two of our primary generator repair coverage areas, with technicians also serving surrounding suburbs across Gauteng.

Generator repair questions
Quick answers on cost, booking, generator faults, servicing and our guarantee. Can't find yours? Ask us directly.
We find the fault and give you a quote before any work starts. If you accept the quote, the call-out fee is waived. If you decide not to go ahead, the call-out or diagnostic fee is payable.
Call or WhatsApp us and we'll give you the earliest available slot for your area. Many faults are fixed on the first visit. If a specific part has to be ordered, we'll tell you how long it should take before any work starts.
Most common faults, like starting problems, carburettor and fuel issues, batteries, starters and alternators, are far cheaper to repair than buying a new generator. If a repair wouldn't make sense because of the unit's age or parts availability, we'll tell you honestly in the quote.
We repair generators across Johannesburg, Sandton, Randburg, Fourways, Midrand, Roodepoort, Centurion, Pretoria, Alberton, Edenvale, Germiston and nearby areas. Send us your suburb to confirm availability.
Diesel, petrol, inverter and standby generators, for homes and businesses, including portable and open-frame units and larger commercial sets. We work on major diesel engine brands such as Cummins, Perkins, Volvo Penta, Caterpillar, Deutz, Doosan, Yanmar and others.
Check that there's fresh fuel, the fuel valve is open, and the choke is set correctly for a cold start. Check the oil level: many generators, especially inverter models, won't start when the oil is low. On electric-start units, check the battery.
Still won't start? It's usually a carburettor, spark plug, fuel or starter fault, and we can diagnose it on-site.
Yes. We repair inverter generators from Honda, Hyundai, Ryobi and other brands, including units that start and then die, surge, or run without giving power at the sockets.
That usually points to the automatic changeover switch (ATS) rather than the generator itself. We diagnose changeover faults and tell you exactly what's wrong. Any work on your home's fixed wiring must be done by a registered electrician.
Follow your manual. As a rough guide, portable generators need an oil change about every 100 running hours, and standby diesel generators need a service at least once a year, or more often if they run a lot during load-shedding. Regular servicing is the best way to make sure it starts when you need it.
Yes. Completed repairs carry a 6-month parts and workmanship guarantee on the specific repair we did, subject to our guarantee terms.
No. Generators produce carbon monoxide, which you can't see or smell. Always run them outdoors, well away from doors and windows. If anyone feels dizzy or nauseous near a running generator, switch it off and get to fresh air.
