Safety warnings
Before digging, check for buried services with Dial Before You Dig (1100). If the post is rotten through, the whole post needs replacing, not just re-concreting.
When to call a tradie
Call a licensed tradie if the work is outside the scope of this guide, involves regulated trades (electrical, gas, structural, waterproofing), or if you discover hidden damage. A professional will typically charge $250–$500.
