What is House Reblocking & Restumping?

Many Australian subfloor building structures consist of either a brick or timber stump construction and deterioration occurs during their lifespan. We offer expert replacement of both types using only the highest quality materials, skilled labor and state of the art machinery.

How To Check The Conditions Of Your Stumps Yourself?
Whilst we highly recommend engaging the services of a professional for this kind of work, we understand that your signs may not be significant enough for you to warrant phoning someone in straight away and you may be looking at ways you can check the condition of your wooden house stumps on your own.
Dig down and around the stump by approximately 5 – 10 cm. Feel the stump for moisture, but also check if the wood gives easily. If it does, it is a good indicator that you may require restumping. It’s important that this work is carried out sooner rather than later, as the stumps can eventually give way if serious damage occurs, meaning it will no longer support the floor above it.

What Is Involved In House Restumping?
Typically, it is common for newer homes to be built with concrete or galvanized steel stumps, these are also used as replacement stumps and should last longer than wooden stumps.
If it is determined that your house requires to be restumped, your home will be slowly and gradually jacked up to the height required to remove the current stumps and replace (or in some cases remove them completely).
It is important to be mindful that although house restumping or reblocking will prevent any further damage and eliminate the risk of collapses, the movement caused by jacking the house may result in some issues to doorframes, tiles, or even further cracks in walls.
