What We Do
Services We Provide
Servicing & Repairs
Stay ahead of costly downtime with proactive care. We service and repair light, heavy and plant machinery on site, covering routine maintenance, mechanical fixes and electrical diagnostic to keep your vehicles and equipment working reliably.
Pre-Purchase Inspection
Buy with confidence, not guesswork. Our pre-purchase inspections check engines, driveline, electrics, tyres and overall condition, then provide a clear report so you understand the true value and any risks.
Tyres
Tyre trouble doesn't have to cause delays to pile up. We come to you to repair and replace tyres for trucks, machinery and light and heavy vehicles, handling punctures and wear on-site to get you rolling to your destination safely and quickly.
24-Hour Breakdown Assistance
When something stops you mid-job, help is close. We offer 24-hour breakdown assistance with rapid diagnoses and on-site repairs from our mobile workshop to get you back to work fast.
Marine Diesel
Marine diesel engines need specialised attention. We service and repair marine diesel systems, checking fuel, cooling and electrics to improve reliability, prevent corrosion issues and keep vessels running safely and smoothly on the water.
Hydraulics
When hydraulics start losing power or blowing seals, the whole machine slows down. We carry out mobile hydraulic fault finding and repairs across the North Coast and Mid North Coast, sorting hoses, fittings and component issues on site so you can get back to work sooner.
Auto Electrics
Intermittent electrical faults can waste hours if they’re not tested properly. We provide mobile auto electrical diagnostics, tracking down wiring, battery, charging and sensor problems and repairing them properly so the issue doesn’t keep coming back.
