Underpinning – the hard truth

If your home has cracks running through its walls, walls that move and doors that jam, the foundations of your home may be sinking. Because of this, you might have considered underpinning as a way to stabilise your home and stop further damage.


But here’s the reality about underpinning – it’s an invasive, difficult, time-consuming and extremely expensive process.


Underpinning your home will –


  • Result in massive holes dug up from beneath your home – even before pins are constructed under the footing

  • On average, underpinning will cost you between $20,000 to $100,000. It may cost even more depending on the size of your house

  • See you removed from your home for months on end.


Underpinning disturbs the physical structure of your house, your wallet and your lifestyle.


It’s a major disruption to your life in every way.

Watch our highly skilled technicians lift and level a wall.
