Mobile Mechanic vs Repair Shop: What Belongs Where

Which is better, a mobile mechanic or a shop?

The job decides, along with where the car is sitting. A mobile mechanic saves you the tow, the rides and the lost day. A shop has a hoist, a roof and every tool on the wall. Neither one is better at everything.

The honest test is simple. Can the job be done properly and safely with the car on the ground, or on proper jack stands, in the spot where it's parked? If yes, mobile usually wins on convenience. If no, it needs a shop, and pretending otherwise just means a half-finished repair in your driveway.

What can honestly be done in a driveway

More than most people think. A lot of modern car trouble is electrical or diagnostic, and that's all done with a scan tool, a meter and a bit of patience. Wear items at the corners of the car are fine too, since the wheels come off with a jack and stands.

The exact car matters. Swapping a starter is a short job on some cars and a half-day job on others, where the starter sits buried under the intake manifold. That's why a good mobile mechanic asks for the year, make, model and engine before quoting, and sometimes says "that one's a shop job" on the phone.

• Warning light and check engine diagnostics
• No-starts, battery testing and battery replacement
• Many starters and alternators, depending on access
• Brake pads and rotors
• Oil service, filters and fluids
• Pre-purchase inspections at the seller's place, before you hand over money

What needs a hoist or shop equipment

Anything that needs a person standing under the car for hours belongs on a hoist. Even shops don't trust a jack alone. Canada's workplace safety centre, CCOHS, says a raised vehicle should be locked on the lift's mechanical lock or held on proper jack stands before anyone works under it. In a driveway, how far you can safely go is set by how high jack stands can hold the car, and that rules out a lot.

Road salt makes the list longer here. Years of brine on Maritime roads can leave brake lines, exhaust hangers and suspension bolts rusted to the point where the job needs heat, cutting or a press. That's shop work, and it's better to know it before the car's in pieces on your driveway.

• Clutches, transmissions and anything that drops the engine or gearbox
• Most exhaust work
• Ball joints, bushings and wheel bearings that need to be pressed
• Rusted-out brake lines on older trucks and cars
• Wheel alignments and tire mounting and balancing
• Welding or rust repair

Condo garages, workplace lots and rented spots

Ask before you book. Plenty of condo and apartment buildings don't allow repairs in the parkade, and some workplace lots don't either. A two-minute email to the property manager saves an awkward conversation with security halfway through a brake job.

Underground garages bring their own limits. Low ceilings, tight spaces between pillars and no room to swing a door can make a simple job hard. A battery or a diagnosis is usually fine. Anything with fluids, like an oil change, is often a no in a shared parkade, and it should be.

A plain driveway, a private lot or the side of a quiet street with room to work is usually the easiest spot. Tell us where the car is when you book, and we'll tell you honestly whether the job fits there.

Winter changes the answer

A brake job on a dry driveway in August and the same job on a sheet of ice in February aren't the same job. Jack stands need firm, level ground, and packed snow over ice isn't that. Slush and salt brine dripping off the car, and the sun gone by 5 p.m. in December, slow everything down.

Most winter calls are no-starts, battery trouble and warning lights, and those are still very doable outside, even at -20 °C. For longer jobs, we might suggest a better spot, such as a cleared driveway instead of a snowbank on the street, a different day, or taking it to a shop. You'll hear that before anyone drives out, not after.

Better still, deal with it before the cold arrives. Transport Canada recommends a check-up by a trained technician before winter and replacing weak batteries before they fail. That's an easy driveway job in October and a miserable one at the end of a tow rope in January.

How OnCall handles jobs that need a shop

We start where the car is. That means diagnosing it in your driveway, at work or at the seller's place, then fixing it on the spot when the job fits. When a car genuinely needs a hoist, an alignment rack or a press, we take it into a shop and manage the repair to the end. You don't get handed a list and told to find someone else, and you don't pay a second mechanic to diagnose the same problem again.

One thing a mobile visit isn't: the provincial Motor Vehicle Inspection. That sticker comes from a licensed inspection station. A pre-purchase inspection is about whether the car is worth buying, which is a different question.

If you're in Dieppe, Moncton, Riverview or Shediac, send the vehicle, the problem and your postal code, or call or text (506) 871-0669. We'll call back, confirm what's going on and give you the price before anyone drives out.
