How Much Does Restumping a House Cost in Australia?

One of the most important maintenance-related jobs you can do for your home is restumping, or reblocking. Many Australians have homes that are stumped, this was a popular way to build houses in the past because of variable soil conditions and even just when it comes down to things like termites. The process, called restumping (also known as Re-blocking) can be vital for protecting your house from damage. This can cost homeowners on average between $10,000 and $30,000.

Restumping costs will depend on a few factors, such as what size and type of house you own, whether your old stumps have already decayed, and how big or complicated the job is. Knowing these will give you an idea of the costs that are likely to arise, so budget well. In this cost guide, we will unpack the cost of restumping on average in Australia and discuss what impacts those costs, as well as how to choose a reputable underpinning contractor that leaves you feeling good about your new foundations.

QUICK TIP: Although the initial cost of fixing foundation problems may seem daunting, timely intervention can prevent more egregious issues with an even greater financial impact. There is a lot of information, and if you keep informed with some understanding behind it then hopefully decisions can be made about your new home that reflect the structural integrity instead of questioning value later on to prevent further damage or decay.

What is Restumping?

Restumping restores and revamps the basic structure of a house. This process simply means all or some of the old stumps supporting your home are being replaced with new ones.

Restumping becomes imperative when the original stumps indicate symptoms of either cracking, sinking or instability.

Restumping ensures that your property does not suffer from any structural issues and the safety of occupants inside, thereby ensuring a long life for your structure.

Restumping Process

There are several steps involved in the restumping process. The early phase involves the detailed inspection of stumps, as well as the floor for any kind of rot, breakages or undulations if it is detected then that stump requires removal from its roots. At the same time, an assessment of soil composition and stump depth is made.

Stump assessment is followed by the jacking out and removal of existing stumps. This is done, where the removal of old stumps from their places becomes difficult and better if done with some proper equipment to lift those things away rightly even so; In some instances, it could even require more digging up.

After any old stumps are removed, it's time to start laying out the new stumps. This is how the stumps are aligned, sited and adjusted for bearing weights.

Having the facility of power packable variables along with galvanised steel stumps is quite appreciable, not only because it saves labouring time but also because a great costly product builds that design where we certainly have way too much ground movement.

Factors Influencing Restumping Cost

The height of your property

If you have a very low home, this will also make it difficult for workers to access the area underneath. You might also need some work done digging or excavating to have your house restumping service completed. Therefore the expense of restumping lower houses is oftentimes much greater. Some alternatively lift the floorboards so they can work on the stumps from inside a house which minimises digging trenches.

If your house is quite high off the ground, they may be able to bring in a mini-digger, thus making subsections easier but costing more on material and less on labour.

Soil conditions

The less stable the soil under your house can also manually increase labour in restumping a job. Send it to an engineer to tell you the depth of your foundation footing. This will prevent mistakes and other expenditures down the line.

Replacing all or some

You should have the restumping work done one after the other in quick succession. If it is done in sections requiring workers to come and go multiple times, the costs increase. You must inspect with the help of stumpers to find out the condition of the stumps and which require replacement.

Existing foundations

If the existing foundations are usable and acceptable, what time (and money) saver can that be? Check the soil tests to ensure that existing foundations are in good condition.

Existing stump holes

It will save a lot of man-hours and dollars if the old stump holes can be used. This, however, will cost more to dig deeper holes.

What is Reblocking?

Reblocking is a related procedure to restumping, only reblocking can be understood as replacing old stumps with other materials such as concrete blocks or galvanized steel piers. This process might include:

Changing the support method hostage means putting additional supports under the pile to reinforce its static stability.

Reblocking can be a bit more in-depth than restumping especially if the job involves significant structural upgrades.

Factors Influencing Reblocking Costs

A number of factors determine how much reblocking costs, the same applies to restumping.

• Location: Costs can vary in each part of Australia Nevertheless, urban areas could be seen to carry higher labor costs over those of rural.


• Type of Foundation: The foundation type and its condition are significant to the cost.
