01
What happens after you call
-
STEP 1
You tell us the set
Brand, capacity and what it is doing — cranking but not starting, tripping on load, overheating, no output. Send a photo of the rating plate on WhatsApp if you are not sure.
-
STEP 2
An engineer is dispatched
We load the likely parts before leaving Apapa, so a common fault is fixed on the first visit instead of turning into a second trip across Lagos traffic.
-
STEP 3
Diagnosis, quote, repair
You get the fault in writing with a price before any work starts. The repair is warrantied, and we tell you what will fail next if it is not addressed.

Industrial engineering services in Lagos
One workshop for the machines that keep a Lagos business running: diesel generators, solar, switchgear, hydraulics and material handling equipment.
Generator installation
Siting, base and foundation, cabling, exhaust and canopy work, ATS integration, load testing and handover for sets from 20 kVA to 800 kVA.
Maintenance contracts
Scheduled servicing on a monthly or annual contract: oil and filters, coolant, batteries, ATS test, load test and a written condition report each visit.
Engine overhaul
Full top and bottom-end overhauls on Perkins, Lister, John Deere and CAT engines — reboring, bearings, injectors, pumps, rebuild and bench testing.
Solar and inverters
Solar PV, inverter and battery systems from 1 kW to 500 kW, including hybrid setups that let the generator rest and cut your diesel bill.
Control panels and wiring
Panel design and assembly, distribution boards, industrial facility wiring, power factor correction and fault finding for factories and warehouses.
ATS and changeover
Automatic transfer switches and manual changeover panels wired and tested, so the set picks up the load cleanly when the grid drops.
Hydraulic systems
Pump and motor repair, cylinder reseal and rebuild, hose and ram replacement, and full system installation on plant and factory machinery.
Forklifts and truck engines
Forklift servicing and repair for warehouses and the ports, plus diesel truck and plant engine work for transport fleets.
03
Cut the diesel bill, or wire the building properly
Solar and inverter installation
We size the system against your actual load, not a guess, then install panels, inverter and battery bank and set the generator to top up only when it must.
- Rooftop and ground-mount solar PV, 1 kW to 500 kW
- Inverter and lithium or tubular battery banks
- Hybrid solar plus generator changeover
- Servicing and panel cleaning contracts
Electrical panels and industrial wiring
Panels built to the load they actually carry, labelled, tested and documented — so the next fault takes minutes to trace instead of a day.
- Control panel design and assembly
- Distribution boards, MCBs and protection
- Factory and warehouse wiring
- Power factor correction and fault finding

Why facilities in Lagos keep our number
-
Based in Apapa
Beside the port and the industrial estates. Short runs to Tin Can, Coconut, Oshodi, Ikeja and the Island instead of crossing Lagos to reach you.
-
2 to 4 hour call-out
A blackout costs a factory more per hour than the repair does. Our breakdown line is answered at night and on Sundays.
-
Engineers, not parts-swappers
Technicians who diagnose the cause. If your AVR keeps failing, you will be told why, not sold a third AVR.
-
Written quote, warrantied work
Price agreed before we open anything, genuine or quality-approved parts, and a warranty on the repair and the installation.
-
One contractor for the plant room
Generator, ATS, panel, solar and hydraulics under one company, so nobody blames the other trade when something trips.
-
Reachable on WhatsApp
Send a photo of the rating plate or a video of the fault. We often identify the problem before the vehicle leaves the yard.

Questions we get asked
How fast can you reach me for an emergency breakdown?
We dispatch from Apapa and reach most parts of Lagos in 2 to 4 hours, day or night. Call or WhatsApp +234 906 611 4686 with your generator brand, capacity and the fault so the engineer arrives carrying the right parts.
Which generator brands do you repair?
Perkins, Caterpillar (CAT), Volvo Penta, John Deere, Lister, FG Wilson, Cummins, Mikano and Tiger, from 20 kVA up to 800 kVA. That covers repair, overhaul, installation and scheduled maintenance.
What does generator repair cost in Lagos?
It depends on the brand, the capacity and the fault, so we diagnose first and send a written quote. No work begins until you approve it, and the price covers parts, labour and the warranty on the job.
Do you install solar panels and inverters?
Yes. We size the system against your real load, then install rooftop or ground-mount solar PV, inverters, battery banks and hybrid solar-generator systems from 1 kW to 500 kW for homes, factories, hospitals and offices.
Do you offer maintenance contracts?
Monthly and annual contracts. Each visit covers oil and filter changes, coolant and battery checks, ATS testing, load testing and a written condition report — which is what stops a set failing in the middle of a blackout.
Where are you, and do you work outside Lagos?
Our workshop is in Apapa, beside the port and the industrial estates we serve. We cover the whole of Lagos and travel nationwide for installations and major overhauls, including Abuja, Port Harcourt, Ibadan and Kano.
