    With consistent wear and tear, your home endures harm that you don't even know is occurring. One problem that could emerge in your home is a slagging foundation. But there is no cause to panic. The magnificent construction world has concocted various strategies where your home can be spared from the foundation giving away and destroying your palace. Although, there are a number of ways that can help solve this issue.

    One of the Methods utilized is known as Underpinning, which is utilized for houses with thick solid walls. As time pass, these concrete and stones age, and the stones start to crack. Due to this, the structure upheld by it begins to sink and cause over the top drive on the supporting pillars. The strategy utilizes jacks to bolster the fragile pillars, and then cement is poured on the jacks to make sure that the support is steady and there is no instability in the structure. On the other hand, for the individuals who lean toward an alternate technique, then house restumping is ideal for you.

    Another method adopted by contractors in house reblocking or house restumping. This can be referred to by both terms, and the procedure includes supplanting the feeble rotting stumps with newer jacks to bolster the spoilt beams at the foundation. However, the problem with this strategy is that it could affect the house over the ground level, and the walls and floors might start to crack. 

    ​Restumping, reblocking, and Underpinning share a thing– they are identified with the foundation on which a house rests. The terms are the substitutions and repair of wooden or solid stumps that bolster the structure. In spite of the fact that the three procedures manage the foundation of the house, they are quite different.

    Restumping, reblocking, and Underpinning has one thing in common – they are related to the foundations on which the structure of a house rests. The terms refer to the process of replacements and repair of wooden or concrete stumps that support the structure. Although the three processes deal with the foundations of the house, they are not the same.


    These two terms can be interchanged while referring to the replacement of foundation stumps. The reason is that both processes have a similar approach. If the concrete or wooden stumps underneath a house start to crack, contractors replace the old stumps with new stumps. Restumping or reblocking involves placing jacks to support the floor as the worn-out foundation is dug out and removed. Once the cracked stumps are removed from the base, new concrete stumps are inserted in their place. This process may cause minor damage to the floors and the walls of the house. Our contractors fix these damages after the new foundation has been laid below the house.


    This process is used exclusively for homes in Melbourne that have walls of brick veneer and a foundation of concrete slabs. Over the years, the weather and ground elements cause the slabs to crack in certain places or sink in certain spots. When this happens, the brick veneer losses its tight alignment, leading to structural instability. The underpinning process uses jacks to prop up the cracked and slumped slabs while a new coat of concrete is poured around the jacks. This stabilizes the brick alignment and adds more stability to the structure.

Consequently, the floor joists are once again lowered on top of the new stumps.

    Frequently Asked Questions

    While it can be quite expensive, it's well worth paying to have it done professionally and to the highest standard. Restumping is a difficult and dirty job, and having it done properly is crucial to the structural integrity of your home.

    In addition to visibly rotted or otherwise deteriorated stumps, some common signs that your house may need restumping are:
    1. doors and windows sticking or not opening and closing properly.
    2. the floor sloping in one direction.
    3. sagging or uneven floors.
    4. cracking interior and exterior walls.

    Usually, houses need restumping due to age, termite damage, or soil movement. In those cases, it's unlikely your home insurance will cover the cost. However, if the stumps have been damaged by an insured event – for example, a pipe burst and caused significant water damage – you might be covered for restumping costs.S

    The major difference between the three processes is that while restumping or reblocking the foundation stumps are completely replaced, but in underpinning, the concrete slabs are not replaced, they are simply reinforced with new material.

    The cost range is between $4,000 and $15,000 to restump and level the house. The price can change depending on the number of stumps to be replaced, the height of the stumps, whether you will be restumping with concrete or steel, and if bearers and joists that have rotted need to be replaced.M

    How Much Does Restumping A House Cost?

    If your floors are sloping in one direction or you've started to see cracks in your walls, it could be a sign that your house needs restumping. So you don't feel stumped by the potential cost, we lay out what this process involves and some factors that can impact what you might end up paying.

    Restumping, also known as reblocking, is when the existing stumps under a house are replaced with new ones. A house may undergo a full restumping (where all stumps are replaced) or a partial restumping (if some of the stumps are still in good condition). Restumping will commonly involve replacing deteriorated timber stumps – for example, those that have rotted or suffered termite damage – with concrete, galvanized steel or rot-resistant timber stumps.

    Restumping can be an important home improvement because stumps support the structure of the house they sit under. According to building inspection company Housepect, if left untreated, defective stumps can lead to structural damage and potentially result in the house totally or partially collapsing.

    What does restumping a house involve?

    Generally, the process will begin with a professional assessing which stumps need to be replaced. According to restumping provider Australian Reblocking, this often involves inspecting the stumps for decay, as well as using a level to see how even the floor is.

    Before starting work, the soil underneath your house should typically also be checked. Global Reblocking says an engineer should assess how deep the stumps should be, depending on the soil condition. This may help to avoid problems in the future.

    The next step is jacking up the house and removing the defective stumps. The remaining stump holes may then be reused, or further digging may be required if they aren't deep enough.

    Next, the new stumps will be positioned, ensuring the house will sit level. Once these have all been installed, the house will then be lowered onto the new stumps and secured.

    What are the Factors that Affect the Cost of House Restumping Services?

    There are many factors that determine how you will be charged for a restumping project. Consider the following points when obtaining quotes from house restumping contractors to manage your finances.

    Type of stumps

    Concrete stumps are generally more expensive than timber stumps. You can potentially save costs on concrete restumping as it offers more stability and does not require occasional checks from building contractors.

    Timbers easily deteriorate, especially when exposed to moisture content. When replacing timber stumps with concrete, the quality of footings to install will affect the price of stump replacement.

    Height of the property 

    The height and length of your stumps will influence the cost of restumping. For example, the cost of a 400mm long and 75x75mm wide concrete stump is around $5. Expect around $10 for a 1200mm concrete stump of the same width.

    Normally, restumping contractors remove the floorboards to set up hydraulic jacks and install the stumps. This manner of reblocking or resetting can have less impact on restumping costs.

    On the other hand, working in low houses may require digging a trench to gain access underneath the property. Using advanced equipment for excavation works will attract increased costs.

    Number of stumps 

    The size and type of property play a major role in determining the number of stumps that you will need. A 150m2 timber house approximately needs 80 stumps, whereas a brick veneer property of the same size may require around 60 stumps.

    A building surveyor or restumping contractor will initially assess the subfloor area to determine the condition of the existing stumps. The number of footings to fix or replace will have an implication on the final pricing.

    To calculate how many stumps are required for your property, measure the total area in square metres. Ask a local contractor for advice to know whether to remove nearly damaged stumps or replace them altogether in one go.

    Duration of work

    Long hours of labour will add to your expenses. The number of days needed to accomplish house restumping projects will depend on the degree of difficulty encountered on-site. Usually, it takes 7 to 14 days to complete the requirements of the job.

    You also have to consider the number of workers who will handle the restumping process. The more manpower you will need, the higher you will be charged.

    Note: Know how long the job will take to calculate the expected cost of labour. HIREtrades Australia's directory of restumping contractors can provide up to three free quotes for you to compare prices.

    Structural amendments

    Post-restumping jobs such as repairing damaged walls and reinstalling floorboards will significantly impact restumping costs.

    A building engineer will have to evaluate the property to ensure its structural integrity. The result of the inspection may require you to hire a home renovation builder to perform repairs on affected walls, ceilings or floors.

    These aspects will incur additional costs.


    Restumping permits also factor in the cost. In Victoria, sole plates are required when restumping a house. The price of concrete sole plates used in restumping can range from $6 to $11, depending on the size.

    Other components, such as ant caps and stump packers which may cost around $1 to $3 per piece, will have an implication on the cost.

    Another consideration is your home insurance. Ensuring your property will help to protect it from potential damages caused by restumping.

    Tips to Hire the Best House Restumping Expert Near You

    When asking for quotations from potential house restumping contractors, ensure to include the same specifications. This will help you compare prices and choose the one that provides the best value for your money.

    If the company supplies low prices for house stumps, consider looking for another prospect. Remember, the quality of materials used will keep you from spending high costs for stump replacement.

    Most importantly, hire a professional restumping contractor with an appropriate licence and insurance. Prioritize a contractor with varied expertise and experience in minor or major house restumping.
