Average Underpinning Costs in Sydney (2025)
In 2025, Sydney homeowners can expect to pay:
- $3,500 – $5,500 per underpinning pier (steel piers or concrete footings)
- $12,000 – $30,000+ for a typical residential underpinning project
- $40,000+ for major structural repairs or large properties
These are
general estimates—a professional inspection is the only way to get an accurate quote.
Factors That Affect Underpinning Costs
1. The Type of Underpinning Method
✔
Concrete Underpinning: $1,500 – $3,000 per linear metre (cheaper but slower)
✔
Steel Screw Piers or Piles: $3,500 – $5,500 per pier (faster, ideal for reactive soils)
2. Severity of the Foundation Movement
Minor subsidence may only need
house leveling or a few piers, while major structural movement could require
dozens of piers and deeper excavation.
3. Soil Conditions in Sydney
Reactive clay (common in Western Sydney) often requires
deeper piers, which increases costs.
4. Access to the Site
If your property has
tight spaces, sloping ground, or landscaping that needs removing, labour and machinery costs will rise.
5. Property Size and Weight
Heavier, double-storey, or older brick homes often require
more extensive underpinning.
Underpinning vs House Leveling – Which Is Cheaper?
Not all foundation problems need full underpinning.
House leveling (adjusting stumps or piers) can cost
as little as $3,000 – $10,000 for minor adjustments.
A proper inspection will determine whether you need a
full underpinning solution or just leveling repairs.
Is Underpinning Worth the Cost?
Absolutely. Delaying foundation repairs can lead to:
- More structural damage (and higher future repair bills)
- Safety risks from unstable walls or flooring
- Reduced property value when selling
What might cost
$15,000 today could easily blow out to $40,000 if left untreated for a few years.
