Cost of underpinning a house in Adelaide

Heritage home with sandstone facade and landscaped garden

The cost of underpinning a house varies greatly with the method chosen to rectify the issues with your foundation. But how do you know if your home needs underpinning?

These are a few of the signs to look out for when performing preventative maintenance around your home;

  • Persistent pools of water
    If you have water consistently pooling in areas around your home, this is a sign of excessive moisture in the soil which can cause your foundation to shift or drop, compromising the structural integrity of your home.
  • Soil dryness
    When we experience under-average rainfall in our winters, dry soil around the home can compact, creating gaps in the ground. This can cause stress to the foundation of your home leading it to sink.
  • Growing cracks in the walls
    Cracking of the walls in your home is the most common sign of the foundation shifting or sinking, particularly if the cracks look like steps, or are wider at one end and thinner at the other.
  • Windows or doors hard to open/close or jammed
    Distorted frames of windows and doors causing them to stick or jam is a tell-tale sign of foundation movement.
  • Sagging or sloping floors or ceilings
    As the foundation shifts or drops, it can compact or pull apart walls or supporting beams, this movement can make your home sit unevenly causing the ceiling or floor to sag or slope.

Your home is your biggest (and most expensive) asset, so it’s better to be safe than sorry. Leaving these issues unresolved will only lead to them becoming more difficult and expensive to fix over time.


To determine the cost of underpinning your home you first need to consult a professional to discuss the scale of the work involved, the number of underpins required, and the type of soil on your property. Most foundation repairs range in cost from $5,000 to $40,000 based on the variations above, with each underpin costing roughly $2,500 to $5,000. Large-scale more serious underpinning repairs can cost up to around $80,000.
