A Townsville workshopthat earns the trust.
Castle Mechanical is a family-run workshop on the corner of Dalrymple and Bayswater Roads in Garbutt. Owner Shane Seawright has been servicing Townsville cars since 2009, with the same straightforward approach the whole time: do the job properly, explain it plainly, charge a fair price.

The workshop
Cnr Dalrymple & Bayswater Rds
Garbutt, Townsville · Open since 2009
Our story
The same hands, since 2009.
Castle Mechanical started with a simple idea: Townsville drivers deserve a workshop that treats their car like its own and tells them the truth about what it needs. Over the years the gear has improved and the workload has grown, but the standard has not budged.
We look after everyday runabouts, family 4WDs and hard-working diesels across Townsville and the surrounding suburbs, from logbook servicing that keeps your warranty safe to brakes, suspension and clutch work. You deal with the people doing the job, not a service desk.

Done by the book
Logbook servicing to the manufacturer schedule with the right parts and oils, so your warranty and history stay intact.

We quote up front and stick to it. If we find something extra, you hear about it before we touch it.
