From my experience working with homeowners, one of the biggest sources of confusion is understanding what “jacking up a house” actually involves — and why the cost can vary so much from one property to another.
This guide breaks down real price ranges, what affects the cost, and what most homeowners don’t realise until after they get a quote.
How Much Does It Cost to Jack Up a House in Brisbane?
The cost to jack up a house in Brisbane typically falls within these ranges:
- $30,000 – $60,000 → basic lift (jacking up only)
- $40,000 – $100,000+ → lift + restumping
- $150,000 – $800,000+ → lift + build under
These figures can vary significantly depending on the structure, site conditions, and scope of work.
In many cases, what starts as a simple lifting job turns into a larger structural project once the condition of the stumps and subfloor is properly assessed.
What Does “Jacking Up a House” Actually Involve?
Jacking up a house involves lifting the entire structure using hydraulic jacks so that work can be carried out underneath.
This process may include:
- lifting the house to a new height
- stabilising the structure during lifting
- installing temporary supports
- preparing for new stumps or structural work
Many homeowners assume it’s a simple lift — but in reality, it’s a highly controlled structural process.
From experience, the lifting itself is only one part of the project. What happens underneath the house is what really determines the final outcome.
Jacking Up Only vs Lift and Restump vs Full Structural Work
One of the most important distinctions is the type of project involved.
Jacking Up Only
- lifting the house without replacing stumps
- suitable when supports are still structurally sound
Typical cost:
$30,000 – $60,000
Lift and Restump
- lifting the house
- replacing deteriorated stumps
Typical cost:
$40,000 – $100,000+
This is very common in Brisbane, especially for older homes where timber stumps are already failing.
From my experience, many homeowners initially expect a simple lift, but inspections often reveal that restumping is necessary.
Lift and Build Under
- lifting the house
- constructing a new level underneath
Typical cost:
$150,000 – $800,000+
Costs increase significantly due to construction, excavation, and approvals.

Several key factors influence the final price.
Size and Weight of the House
Larger houses require more lifting points, structural support, and labour.
Height of the Lift
The higher the house is lifted, the more structural work is required.
Condition of Existing Stumps
This is one of the biggest variables.
From experience, many Brisbane homes have stumps that are already deteriorating — which means restumping becomes part of the project.
Soil Conditions and Drainage
Soil movement and drainage issues can affect stability and increase the complexity of the work.
Access Under the House
Limited access can significantly increase labour time and difficulty.
Future Plans (Renovation or Build Under)
If the goal is to build underneath later, the project may require additional planning and structural preparation.
Hidden Costs Most Homeowners Don’t Expect
One of the biggest surprises for homeowners is how many additional costs are not included in the initial lifting quote.
Plans, Engineering and Approvals
- drafting plans
- engineering reports
- council approvals
Service Reconnections
- plumbing
- electrical
- drainage
Excavation and Slab
If building underneath, excavation and concrete work can add significant cost.
New Stairs and Structural Additions
These are often required once the house is lifted.
From my experience, this is where many projects exceed the original budget — not because of the lift itself, but because of everything around it.

Many homeowners run into issues due to a few common mistakes.
Assuming It’s Just a Simple Lift
In reality, lifting is only part of the process.
Not Checking the Condition of the Stumps
If the supports are failing, lifting alone won’t solve the problem.
Waiting Too Long
Structural movement tends to get worse over time, which can increase the complexity and cost of the project.
Focusing Only on Price
Choosing a contractor based only on cost can lead to incomplete or incorrect work.
How to Get an Accurate Quote in Brisbane
The only reliable way to determine the true cost is through a detailed inspection.
A proper assessment should include:
- stump condition
- structural movement
- soil and drainage
- access under the house
- overall structural integrity
From my experience, homeowners feel far more confident once they understand exactly what’s happening beneath their home.
Clear explanations make a big difference in what is often a stressful situation.
Conclusion
Jacking up a house in Brisbane is rarely just about lifting the structure.
It’s about understanding the condition of the home, identifying the real problem, and making sure the solution addresses it properly.
From my experience working with Brisbane homeowners, the best outcomes always come from:
- proper assessment
- realistic planning
- focusing on long-term structural stability
When done correctly, lifting and stabilising a house can protect it for decades and give homeowners real peace of mind.
