Equipment service, explained clearly
Different systems. Different tests. One clear service record.
Explore service plansOur mobile work is organized around the system that needs attention, not a generic checklist of parts to replace. Every job starts by confirming what the machine is doing and what can safely be inspected on site.
FIELD MAINTENANCE01 / Service focus
On-site maintenance & repair
Maintenance, inspection and repair where the machine is parked, with findings documented by unit.
Fluid checks, filter service, greasing, general repairs and follow-up recommendations are recorded against the equipment.
TEST BEFORE REPLACING02 / Service focus
Electrical & diesel diagnostics
Troubleshooting starts with the symptom, measurements and the proper service information.
Fault codes provide direction. Circuit tests, mechanical checks and repeat tests support the actual repair decision.
PRESSURE · FLOW · CONTROL03 / Service focus
Hydraulic systems
Pressure, flow, hoses, cylinders and valve problems require hydraulic testing rather than guesswork.
The machine's hydraulic design and OEM procedures determine which readings matter and how to test safely.
Imagery illustrates representative field-service work. It is not a photograph of a particular customer repair, a promise that every test can be completed on site, or evidence of manufacturer certification.
Service plans & packages
Bronze, Silver and Gold with no mystery charges
Travel stays separate at $1.10/km round trip. Package prices include the listed labour hours and stated material allowance, before HST and posted fees. OEM oil, grease, filter and coolant requirements always override the generic package allowance.

Select Gold packageParts & materials · transparent quoting
Different filters and fluid capacities mean different material costs.
Published package prices are starting prices with the stated labour and standard material allowances, not a flat guarantee for every make and model. We confirm the machine or VIN, engine, filter part numbers, actual fluid capacities and OEM specifications before finalizing the written estimate. Specialty filters and higher-capacity services are quoted separately.
Package base
Included labour hours + published standard material allowance
Adjustments, if applicable
Approved extra materials / upgrades + additional authorized labour
Separate charges
Round-trip travel at $1.10/km, applicable posted fees and HST
The included material allowance is credited against the applicable items on the estimate. Only the approved difference or additional quantity is charged, never the same included part twice.
One travel charge applies to a coordinated fleet visit at one site. Separate visits or different sites require separate travel quotes.
