Licensed mobile mechanic repairers licence ​MVRL57595

We are a licensed mobile vehicle workshop.

We do NOT use unreliable third party mechanics to conduct any of our inspections.

Mechanics are hired directly by Double Chex with the right inhouse training received to ensure quality control.

​Our mobile mechanics repairers licence will also allow us to disassemble and diagnose any components in accordance with manufacturers standards – upon request. 

Compression Leak Testing
​(head-gasket condition)

The Compression leak test detects any presence of Co2 (carbon dioxide) within the cooling system.​

​The presence of Co2 indicates there is an internal combustion leak within the engine which will ultimately cause compression drop in the cylinders and resultant head gasket failures. ​​


Please note that the internal engine compression check is NOT completed during our inspection process.

​Beware of other pre purchase inspector’s claiming that the engine compression test is completed – this is entirely false.  A ‘conventional’ engine compression test will require partial disassembly of engine components and will take hours to complete depending on the exact engine configuration.

What is a paint thickness test?

A coating thickness gauge is utilised to test the coating thickness of ferrous and non-ferrous metals (otherwise known as magnetic and non-magnetic metal surfaces).

When conducting an inspection and a piece of equipment, we are able to determine not only the thickness of the subject panel coating (i.e paint), but to determine whether there are any underlaying imperfections that we cannot see to the naked eye.
These imperfections include;

  • Body rust
  • Chassis rust
  • Body filler
  • Substandard welds
  • Rust plates
  • Fish plates
  • Sand blasting
  • Primer thickness
  • Body deadener

All of the above mentioned are crucial factors in determining if the subject vehicle deemed as being safe with no other unexpected pre-existing damages or repairs.
In short, a coasting thickness or paint thickness test is crucial when completing vehicle inspections. No matter if it is for a pre-purchase inspection, warranty inspection or repair dispute inspections.
