“Took my van in with a fuel leak. Chris was fantastic to deal with, had my van in and out in 36 hours and I couldn't be happier. My quote was communicated well and fair and they hit the target. I'll be bringing my vehicle to them from now on any time it needs work. Thanks guys.”

“I had a series of truly terrible issues with a new-to-me truck and failed rebuilt engine (rebuilt elsewhere). Upon professional advice, I had my truck towed to Supertech. They gave me superb service and went over and above navigating warranties and getting my truck fixed and running. I highly recommend Supertech. Their work and customer service is exceptional.”

Experienced Technicians. Properly Mentored Apprentices.

Many large repair operations rely heavily on inexperienced technicians, which can lead to misdiagnosis, unnecessary parts replacement, and repeat visits.

At SuperTech Diesel, we proudly invest in the future of our trade by training apprentices, but unlike operations where apprentices often outnumber journeymen, our apprentices are closely mentored and supervised at every stage. In many cases, our fully certified Red Seal technicians outnumber apprentices 5 to 1 or more, ensuring your vehicle benefits from decades of combined experience, oversight, and craftsmanship.
