How we chose

These are RemitRight's editorial picks — not a paid directory and not a public vote. No business paid to be included, and inclusion cannot be purchased. We applied objective, verifiable criteria:

  • Physically located in or anchored to the city's industrial / trucking district (verified by address).
  • A strong, well-established reputation with commercial operators and owner-operators — backed by a meaningful volume of reviews, not a high score on a handful.
  • A track record of continuous operation serving fleets and the trucking community.
  • Genuine heavy-duty capability — diesel engine, driveline, brakes, electrical/diagnostics, trailer or welding/fabrication work — not light-duty auto service alone.
  • Status as a CVSE-recognized Designated Inspection Facility, or a strong commercial-inspection reputation, treated as a key signal.
  • Mobile and after-hours roadside capability given weight, since on-road downtime is what costs operators most.
  • Locally owned independents valued alongside well-run dealer and banner service departments.

Customer-review figures change over time and were used as a signal, not republished. Featured a shop and think a detail is off, or run a Surrey heavy-duty or diesel shop that belongs here? Let us know. Run one of these shops? Claim your listing to set your live availability — free.

Keeping a commercial truck legal in BC

Commercial vehicles in BC run under the National Safety Code and are overseen by CVSE (Commercial Vehicle Safety and Enforcement). Most commercial trucks and trailers above the regulated weight need a periodic commercial vehicle inspection, performed by a licensed inspector at a Designated Inspection Facility, with the inspection interval depending on the vehicle's class and use.

A current inspection decal is what keeps you legal at a roadside check — and a defect that CVSE flags as out-of-service can pull a truck off the road on the spot. That's why a shop with a strong inspection reputation and quick turnaround is worth more to an operator than a cheap hourly rate: it keeps the truck compliant and earning.

For owner-operators and fleets, the same logic drives preventive maintenance — scheduled service and mobile/roadside coverage cost far less than an unplanned breakdown on the highway. Surrey's heavy-duty trade concentrates in Port Kells — the industrial pocket east of 192 St near the Highway 1 and 15 truck routes — which is where most of these shops sit.

What to look for in a heavy-duty or fleet shop in Surrey

  • Confirm the shop is a CVSE Designated Inspection Facility if you need commercial vehicle inspections done on-site rather than farmed out.
  • Ask which engines and brands they actually work on — Cummins, Cat, Detroit, Volvo, Paccar — and whether engine work is done in-house or sublet.
  • For a fleet, ask about scheduled preventive-maintenance programs and fleet accounts; planned service beats roadside breakdowns every time.
  • Check for mobile and after-hours roadside service — a truck stuck on the shoulder is lost revenue by the hour.
  • Get the repair authorized in writing with an estimate before work starts, and confirm shop rate, diagnostic time and parts markup up front.
  • Weigh turnaround and shuttle/loaner options as heavily as price — uptime, not the invoice, is the real cost.

A note on getting paid

Heavy-duty repair bills are large, and a lot of the work is for fleets and brokers on net-30 terms — so the shops that thrive run a tight back office, not just good bays. Two habits protect the business: get a signed work order or purchase order for every job and the hours before the wrenches turn, and give slow-paying accounts an easy way to clear a big balance — a payment-plan link, so a stuck five-figure invoice turns into a few automatic payments instead of a write-off or a lien.

This guide is sponsored by RemitRight, which does exactly that for trade and trucking businesses across Canada — its AI texts overdue customers and turns balances into automatic payment plans, paid straight to you. It's completely free for your business, on every invoice — never a trial. RemitRight only earns anything when a customer can't pay in full and chooses to split the balance into installments: a small percentage is added that the customer pays, not you. Pay in full and it costs everyone nothing.
