Built on
heavy iron
and kept promises.
What started as one diesel mechanic with a service van in 2005 has grown — quietly, deliberately — into one of Ontario's most respected mobile workshops for heavy industry.
Every job is handled by a senior technician. Every invoice is transparent. Every machine leaves our care better than it arrived.
Our story →Six services,

From the diagnostic plug to the welded seam, every service NIRO offers is performed in-house, on-spec, and by a senior technician with two decades of heavy-equipment muscle memory.

How a job
actually works.
Initial assessment
One call establishes urgency, location, and what the machine is doing. We match the right technician.
Transparent quotation
Parts priced before the job starts. No estimates that grow after we open the machine.
Precision execution
Work done to manufacturer spec by a senior technician. Photographed, logged, tested under load.
Field handover
Full service record delivered at invoice. Machine handed back with zero punch list.
From the
journal.
Technical insight from two decades in the field — written by the technicians, not the marketing department.
Machine down? We answer.
No ticket queues. No menus. A senior technician — including on statutory holidays.
