The Short Answer
Restumping cost in Australia typically ranges from $4,000 to $20,000 for a standard residential home, though complex jobs can exceed $30,000. On a per stump basis, expect to pay $400 to $1,000 depending on the material (timber, concrete, or steel) and the difficulty of access. A typical three-bedroom weatherboard home with 40 to 60 stumps costs $10,000 to $18,000 for a full restump using concrete or steel stumps.
Does Your House Actually Need Restumping?
Before worrying about restumping cost in Australia, it helps to know whether your house actually needs it. Many older Australian homes, particularly in Victoria, Queensland, and parts of NSW, were built on timber stumps that can deteriorate over time due to moisture, termite damage, and soil movement. Here are the warning signs to watch for.
Floors that slope or feel uneven. If you place a ball on the floor and it rolls consistently in one direction, your stumps may be sinking unevenly. Some unevenness is normal in older homes, but noticeable slopes that have worsened over time suggest foundation issues.
Cracks appearing in walls or ceilings. As stumps shift or sink, the frame of the house moves with them. This shows up as cracks in plasterwork, particularly around door frames and window openings. Hairline cracks in older homes are common and not always related to stumps, but widening or diagonal cracks are worth investigating.
Doors and windows that stick or no longer close properly. When the frame of a house shifts due to stump movement, door frames go out of square. Doors that used to close easily and now drag on the floor or refuse to latch are one of the most noticeable early signs.
Bouncy or sagging floors. If sections of your floor feel soft or springy when you walk across them, the stumps or bearers beneath may be failing. This is particularly common in hallways and high-traffic areas where the repeated load accelerates deterioration.
Visible stump damage. If you can access the subfloor space beneath your home, inspect the stumps directly. Look for timber stumps that are soft, rotting, or show signs of termite damage. Concrete stumps can crack over time. Any stump that has visibly shifted from vertical is a concern.
If you notice several of these signs at once, it is worth having a restumping specialist or structural engineer inspect the property. A professional assessment typically costs $200 to $500 and gives you a clear picture of what is needed before you start getting restumping quotes.

Prices are indicative averages. Actual restumping cost in Australia will vary based on home size, stump type, access, soil conditions, and your location.
Restumping Cost in Australia by State
Restumping cost in Australia varies between states due to differences in labour rates, soil conditions, and the prevalence of stumped homes. Victoria and Queensland have the highest volume of stumped homes, which means more providers and generally more competitive pricing. States where stumped construction is less common may have fewer specialist providers.
| State | Full Restump, 3 Bed Home (Approx.) | Per Stump, Concrete (Approx.) |
|---|---|---|
| NSW (Sydney) | $12,000 – $22,000 | $550 – $850 |
| VIC (Melbourne) | $10,000 – $18,000 | $500 – $800 |
| QLD (Brisbane) | $9,000 – $16,000 | $450 – $750 |
| WA (Perth) | $10,000 – $18,000 | $500 – $800 |
| SA (Adelaide) | $9,000 – $16,000 | $450 – $750 |
| TAS | $8,000 – $15,000 | $400 – $700 |
| ACT (Canberra) | $11,000 – $20,000 | $500 – $800 |
| NT (Darwin) | $11,000 – $20,000 | $500 – $850 |
Timber vs Concrete vs Steel Stumps
The material you choose for your new stumps significantly affects restumping cost in Australia and the long-term performance of the foundation. Each material has clear trade-offs.
Treated timber stumps are the most affordable option upfront, typically costing $400 to $600 per stump installed. They are lighter and easier to work with in tight spaces. However, timber stumps are susceptible to termite damage and moisture rot over time, even when treated. Timber is generally no longer recommended by building professionals for new installations unless budget is the primary constraint, and they typically need replacing again in 15 to 25 years.
Concrete stumps are the most popular choice for restumping in Australia. They cost $500 to $800 per stump installed and offer excellent durability with a lifespan of 50 years or more. Concrete is resistant to termites and moisture but can crack over time in reactive soils that expand and contract with moisture changes. Concrete stumps are heavy, which can make installation more difficult in homes with limited subfloor clearance.
Galvanised steel stumps are the premium option at $600 to $1,000 per stump installed. They are lighter than concrete and extremely strong, making them well suited to homes with tight access or reactive soils. Steel stumps are often adjustable, which means minor relevelling can be done in future without full restumping. Their main vulnerability is corrosion in highly acidic soils, though galvanised coatings significantly extend their life. Steel is increasingly the recommended option for homes in areas with reactive clay soils.
For most homes, concrete stumps offer the best balance of cost, durability, and performance. Steel stumps are worth the premium in areas with reactive soils or where future adjustability is valuable.
What Affects Restumping Cost in Australia?
Understanding the key cost drivers helps you evaluate quotes and anticipate what your project will cost.
The number of stumps is the most direct cost factor. Every home has a specific number of stumps supporting the floor frame. A small cottage might have 30 to 40 stumps. A larger family home could have 60 to 90 or more. The total restumping cost in Australia scales directly with the stump count. A professional inspection will determine exactly how many stumps your home has and how many need replacing.
Subfloor clearance and access is often the factor that separates straightforward jobs from expensive ones. Homes with generous subfloor height (400mm or more of clearance between the ground and the bearers) are relatively easy to work under. Homes with very low clearance may require excavation to create enough working space, which adds significant time and cost. Homes on sloping blocks or with limited access from the sides can also increase difficulty.
Soil conditions influence both the depth of the new stump footings and the type of stump recommended. Reactive clay soils that expand when wet and shrink when dry require deeper footings and often favour steel stumps with adjustable bases. A geotechnical soil test (typically $300 to $500) may be recommended to determine the appropriate footing depth and stump specification.
Whether the house needs lifting adds to restumping cost in Australia. Restumping involves jacking the house up off the old stumps and lowering it onto the new ones. If the house has settled significantly, correcting the levels may require more extensive jacking and adjustment work. In some cases, homeowners choose to raise the house height during restumping to improve subfloor ventilation, which is additional work.
Additional structural repairs are sometimes discovered during restumping. Rotted bearers, damaged joists, or termite damage to the floor frame may need repair once the house is lifted and the framing is exposed. These repairs are charged on top of the restumping quote and can add $1,000 to $5,000 or more depending on the extent of the damage.
Building permits are required for restumping in most states. In Victoria, for example, a building permit is required for all restumping work. Permit costs typically range from $200 to $800 and the work must be inspected and signed off by a registered building surveyor.
The Restumping Process Step by Step
Understanding what happens during restumping helps set expectations for cost, timeframe, and disruption.
Step 1: Inspection and quote. A restumping specialist inspects your subfloor, assesses the condition of existing stumps, and provides a detailed quote specifying the number of stumps, material, and any additional work required. Getting two to three quotes is standard practice.
Step 2: Permits and engineering. If a building permit is required in your state, this is lodged before work begins. For homes with complex soil conditions, a structural engineer may specify the footing design.
Step 3: Preparation. Furniture may need to be moved or secured. Plumbing, gas, and electrical connections that pass through the subfloor may need temporary disconnection. The restumping team will advise on what preparation is needed.
Step 4: Jacking and removal. The house is progressively jacked up section by section using hydraulic jacks. Old stumps are removed once the weight is transferred to the temporary supports. This is the most labour-intensive phase.
Step 5: New stump installation. New stumps are set into excavated holes with concrete footings, positioned to ensure the house sits level. The depth and size of the footings depend on the soil conditions and engineering specifications.
Step 6: Lowering and securing. The house is carefully lowered onto the new stumps and secured. Levels are checked and adjusted across the entire floor to ensure the house sits evenly.
Step 7: Final inspection. A building surveyor inspects the completed work to verify it meets building standards and issues a certificate of final inspection.
The entire process typically takes three to seven days for a standard home, though larger or more complex jobs can take longer. Most homes remain liveable during restumping, though some disruption is inevitable.
How to Save Money on Restumping Costs in Australia
Restumping is not a project where cutting corners is advisable, since the consequences of poor foundation work are expensive and potentially dangerous. That said, there are legitimate ways to manage your restumping cost in Australia.
Get at least three quotes. Restumping quotes can vary substantially between providers for the same job. Three quotes give you enough data to identify the market rate for your specific project and flag any outliers that are suspiciously cheap or unusually expensive.
Consider partial restumping if appropriate. If only a portion of your stumps are failing, replacing only the affected stumps rather than restumping the entire house can significantly reduce the cost. Your inspector can advise whether partial restumping is a viable option or whether full restumping is necessary.
Compare stump materials carefully. Steel stumps cost more per unit than concrete but their adjustability can save money on future relevelling. Concrete stumps are the best value for most standard applications. Timber is cheapest upfront but the shortest-lived, so it may cost more over the long term.
Address drainage issues first. Poor drainage around your home accelerates stump deterioration. Before spending on restumping, ensure your drainage is directing water away from the subfloor. This extends the life of your new stumps considerably.
Bundle additional work. If you also need subfloor ventilation, bearer replacement, or underpinning work, having these done at the same time as restumping is more cost-effective than separate projects because the subfloor is already exposed and accessible.
How to Find a Reliable Restumping Specialist in Australia
Restumping is specialist work that should only be performed by experienced, licensed professionals. The quality of the work directly affects the structural integrity of your home for decades to come.
Check licensing requirements in your state. In Victoria, restumping contractors must be registered builders. In Queensland and other states, similar licensing requirements apply for structural building work. Always verify that your contractor holds the relevant licence for your state.
Look for specialist restumping companies rather than general builders. Companies that focus specifically on restumping and reblocking have the specialist equipment, experience, and understanding of foundation issues that general builders may lack.
Ask for references and examples of completed work. A reputable restumping company will have a portfolio of completed projects and be willing to provide references from previous clients. Ask specifically about homes similar to yours in size and construction type.
Confirm insurance coverage. Restumping involves significant structural work. Your contractor should carry public liability insurance and structural warranty insurance. Ask for evidence of both before work begins.
Be cautious of very low quotes. Restumping quotes that are dramatically below the market rate often indicate corners being cut. This might mean insufficient footing depth, incorrect stump specifications, or skipping required permits and inspections. The consequences of poor restumping work are serious and expensive to rectify.
Frequently Asked Questions About Restumping Costs in Australia
How much does it cost to restump a house in Australia?
Restumping cost in Australia for a standard three-bedroom home typically ranges from $10,000 to $18,000 for a full restump using concrete stumps. Partial restumping of 10 to 20 stumps typically costs $3,000 to $8,000.
How much does restumping cost per stump?
Per stump costs range from $400 to $600 for treated timber, $500 to $800 for concrete, and $600 to $1,000 for galvanised steel. These prices include the stump, footing, and installation labour.
How long does restumping take?
A full restump of a standard home typically takes three to seven days. Larger homes or those with access difficulties may take longer. You can usually remain in the home during the work.
Do I need a building permit for restumping?
In most Australian states, yes. Restumping is classified as structural building work and requires a building permit. Your contractor should arrange this as part of the project.
How often does a house need restumping?
This depends on the stump material and conditions. Timber stumps typically last 15 to 25 years. Concrete stumps last 50 years or more. Steel stumps also last 50 years or more in suitable soil conditions.
Will restumping fix my cracked walls?
Restumping addresses the foundation issue causing the movement. Some cosmetic cracking may close naturally once the house is relevelled. Wider cracks may need patching after the restumping is complete. In a small percentage of homes, minor new cosmetic cracking can occur as the house adjusts to its corrected level.
Is restumping covered by home insurance?
Standard home insurance policies in Australia generally do not cover restumping as it is considered maintenance rather than damage from an insured event. If stump damage results from a specific insured event like storm damage or significant ground movement, partial coverage may apply. Check your policy wording with your insurer.
Final Thoughts
Restumping cost in Australia is a significant investment, but it is one that protects the most valuable asset most Australians own. Deteriorating stumps do not get better on their own, and the longer foundation issues are left unaddressed, the more extensive and expensive the repairs become.
If your home is showing signs of stump failure, the most cost-effective step is getting a professional inspection sooner rather than later. Early intervention, when only some stumps need attention, is significantly cheaper than waiting until the entire foundation needs replacing.
Choose a licensed specialist, get multiple quotes, and invest in quality materials that will support your home for decades. Restumping done properly is a one-time investment that should last 50 years or more with concrete or steel stumps.
