Common signs of subsidence in Auckland homes include diagonal cracks in walls, especially near windows and doors. You may also notice sticking doors and windows, sloping or uneven floors, and skirting boards pulling away from walls. Other signs are cracks where an extension meets the main house, warped wallpaper, and noticeable property leaning. If you see these issues, especially if they are getting worse, don’t hesitate to contact Grace Foundation Solutions. We offer a free evaluation to find the problem and suggest the right solution for peace of mind.

Common Questions About Subsidence Repairs in NZ
What is subsidence and how do I know if my house has it?
Subsidence is when the ground under a property sinks. Look out for cracks, sticking doors, or uneven floors. In New Zealand, it often occurs because of soil type, tree roots, drainage issues, or earthquakes.
What causes subsidence in New Zealand homes?
Common causes include clay soils in Auckland and Wellington, poor drainage, leaking pipes, heavy rain, and flooding. Tree roots and earthquake damage are also contributing, especially in Christchurch and Wellington.
How do I fix subsidence in my home?
Repairs depend on severity. Options range from underpinning foundations, soil stabilisation, resin injection, ground improvement, drainage fixes, to re-levelling the house. Our free site evaluation is your first step.
How much does subsidence repair cost in New Zealand?
The resin injection or resin underpinning cost in New Zealand with Grace Foundation Solutions usually ranges from $4,000 to $15,000, but it can be higher in severe cases.
Does EQC or insurance cover subsidence repairs?
EQC generally covers natural disasters and related ground damage (like earthquakes, landslides, or floods), while private insurance may exclude gradual land movement. Claims depend on the cause, so assessment and documentation are essential.
What’s the difference between settlement and subsidence?
Settlement is normal slight sinking of a new build as soil compresses under weight. Subsidence is ongoing or uneven movement, often worsening over time and needing repair.
Can subsidence be prevented?
Yes, preventative maintenance is essential. Our drainage works team does CCTV maintenance surveys yearly on sites that may sink. To reduce risks, manage tree planting near foundations. We also check that the roof gutters are in good shape. Additionally, we look for damage after earthquakes, floods, or other natural disasters.
Who do I call first if I suspect subsidence?
Start with Grace Foundation Solutions. We offer a free site evaluation to determine whether subsidence is a factor and whether you need a structural or geotechnical engineer. We can project manage any resources depending on our findings, and insurers may be involved later.
How long do subsidence repairs take?
Resin underpinning injection may take a few days. In contrast, concrete underpinning or primary stabilisation can take weeks or months. The timeline also depends on the weather, soil conditions, and consent requirements.
