Our Process

Step 1

Talk through the symptoms

We’ll ask a few questions about what’s happening and how long the issue has been occurring.

Step 2

Inspect and assess

We’ll assess what’s going on, including site access and whether any excavation or trenching may be required, then explain likely causes and options.

Step 3

Repair, maintain, or plan the next step

We’ll complete the agreed work. If digging is needed, we use specialised equipment (including mini excavators) to create safe access and trenches for pipes and drainage, and we’ll advise how to keep your system working reliably.

Septic System Care Tips
