Do I have to commit to repairs after a diagnostic?

No. You are free to take the findings elsewhere. Many customers stay with us because the diagnostic already builds the repair plan.

Can you diagnose over the phone?

We can give a general steer on the phone, but a proper diagnosis needs eyes on the machine or the component.

Do you test pump and relief pressures?

Yes, where the machine has ports or fittings that let us take safe pressure readings.

What causes repeat seal failures?

Usually contamination, heat, a scored rod or a system pressure that is set too high. A diagnostic identifies which it is.

Can you diagnose on site?

Often yes, subject to the job, your location and current workload. Call 09 430 8070 to check.

Workshop vs on-site

Inspection, pressure checks and most fault finding can be done on site as part of our mobile service.

Deeper testing that needs bench equipment or a controlled setup is done at the Whangārei workshop. On-site availability depends on the job, your location and current workload.

What you get out of it

Fewer parts thrown at the problem
A clear repair scope with a realistic cost
Confidence that the underlying cause is addressed, not just the symptom
