Residential FAQs
Common warning signs include cracks in walls or ceilings, doors and windows that jam or no longer close properly, sloping or bouncy floors, and gaps appearing around skirting boards or architraves. If you notice any of these, it's worth having a specialist assess the cause before it worsens.
Not every crack points to a structural issue, hairline cracks in plaster can be cosmetic and caused by normal settling. However, cracks that are wide, diagonal, growing over time, or paired with sticking doors and sloping floors usually indicate underlying foundation movement that should be assessed.
Yes. In most cases a sinking slab can be stabilised and re-levelled using techniques such as chemical underpinning, resin injection or void filling, without the need to demolish or rebuild. A site assessment determines the most suitable method for your property.
Foundation movement rarely resolves on its own. Left untreated, ground instability typically continues, leading to wider cracking, worsening slopes and more costly repairs down the track. Early intervention is generally the most cost-effective approach.
Most residential stabilisation works are completed within a few days to a couple of weeks, depending on the extent of the movement, the remediation method used and site access. Your specialist will provide a project timeframe as part of your assessment.
In the majority of cases, homeowners are able to remain in the property while works are carried out, as most stabilisation methods are low-disruption. Your project team will let you know in advance if any part of the process requires you to vacate the area.
Yes, unresolved cracking or foundation movement can affect a property's value and make it harder to sell or insure. Addressing the issue with a documented, professional remediation gives buyers and valuers confidence the underlying cause has been resolved.
Foundation movement is most commonly caused by reactive clay soils expanding and contracting with moisture changes, poor drainage, tree roots drawing moisture from the ground, leaking pipes, or inadequate original footings. A site assessment identifies the specific cause for your property.
