Average Foundation Repair Costs in Australia

The cost of foundation repair varies depending on the size of the property, the severity of the damage, and the repair method used. Below are general price ranges:

  • Minor crack repairs: $2,000 - $ 5,000
  • Partial underpinning/ Slab re-leveling: $5,000 - $15,000
  • Full underpinning (Avarage homes): $20,000 - $50,000+
  • Large or commercial projects: $40,000+

(Note: These are indicative ranges. A detailed on-site inspection is required for an accurate quote.)

Key factors That Affect the Cost

Several factors influence the overall cost of a foundation repair project:

  1. Size of the property - Larger buildings require more piers and materials.
  2. Extent of damage - Minor cracks are cheaper to fix than severe settlement.
  3. Soil type - reactive clay soils often need deeper, more expensive underpinning.
  4. Repair method - Push Pier system, injection, or traditional underpinning.
  5. Accessibility - tight spaces, basements, or restricted access increase costs.
  6. Engineering & council approvals - required in many states, adding to cost but ensuring compliance.

Is Underpinning Covered by Insurance?

Usually not covered if caused by soil movement or natural settlement. May be covered if liked to a sudden event (like a burst water pipe).
