Yes, we repair generators in Glen Marais, from small petrol sets and canopied diesels at family homes to the shared sets in townhouse complexes, on site. We are open 24/7 and arrive within 1 hour for breakdowns; we test the fault first and quote in writing before any work.
Glen Marais is one of Kempton Park’s established residential suburbs, with freestanding family homes, townhouse complexes and neighbouring Birchleigh just up the road. Most generators here are small to medium canopied diesels or petrol sets that sit quietly for weeks and then have to run a household through an outage.
That pattern decides how we approach a visit. We test the battery and charger first, check the age and condition of the diesel or petrol in the tank, and then run the set with your house load connected. In a complex, we also check the changeover and the supply to each unit, because one shared set serves several households.
We also work on business sets across Kempton Park, including the warehouses in Isando and Spartan, so if you run a business nearby you can book your home and business sets with one call.
Breakdowns attended 24/7. We diagnose first, then quote the repair in writing.

Glen Marais calls usually involve a home set that has been standing: the battery has run down, the fuel has aged, or the automatic start has stopped working.
We test the battery under load and check the charger, terminals and any latched alarm before we suggest a new battery.
If the battery is new and still goes flat, we test the charger and the charging alternator on the engine.
If the set starts on the key but ignores an outage, we check the controller and the mains sensing at the changeover.
We meter the output with your appliances running and trace the fault to the AVR or alternator.
Old petrol and a varnished carburettor are the usual cause. We clean or repair the fuel system and set it up correctly.
A complex set has to start on its own, transfer the load and keep every unit supplied. When some Glen Marais units stay dark or the set ignores an outage, we test the controller, the changeover and the supply to each unit, quote the trustees in writing and confirm the repair with a real mains failure. Planned servicing and maintenance plans for complex sets are on the Kempton Park servicing and maintenance page.
Most Glen Marais sets are residential: small canopied diesels, petrol sets and a growing number of automatic standby sets in complexes.
We service and repair the brands below. If your set is a different make, send us the model and we will tell you what we can do.
Servicing and repairs for house sets, with the battery, fuel and changeover checked on every visit.
Shared standby sets serviced on a schedule, with a record of each visit for the trustees.
Shops and offices on the main roads, and warehouse sets in nearby Isando and Spartan.
A flat battery, a faulty charger and a controller fault can look the same. We find which one it is.
We work on both, so the portable set in the garage and the canopy at the side of the house are covered.
