Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect brickwork, plaster and rendered finishes for crack patterns that suggest structural movement (step cracking, diagonal shear cracking, separation at openings) versus shrinkage or minor settlement. This matters because the crack type, location and width help indicate whether footings, walls or framing may be compromised and what follow-up is needed.
Where the home has a subfloor, we check for uneven or deteriorated stumps, bearer sag, damp subfloor conditions and evidence of past packing. These issues can drive sloping floors, sticking doors and ongoing movement, and they often become expensive if left until renovations uncover them.
We enter the roof void (where safe) to assess rafters/trusses, strutting, bracing, tie-down points and signs of spread or deflection. We also look for water staining and timber decay linked to roof leaks, because moisture-damaged framing can reduce load capacity and create safety hazards.
Canterbury homes are frequently remodelled to open up living zones. We look for signs that load-bearing walls may have been altered without adequate beams, posts or support, including ceiling dips, cracking above openings, unusual bulkheads and inconsistent framing. Identifying these risks early helps you request structural documentation or budget for rectification.
We inspect bathrooms, laundries, balconies/decks (where present) and external wall bases for moisture entry that can lead to rot, corrosion and loss of structural performance. We also check for conditions that keep the base of walls wet, such as poor drainage, bridging of damp-proof courses and leaking plumbing points.
We assess visible steel lintels over windows/doors, cracking at openings, and signs of corrosion expansion in masonry elements. In older and renovated properties, rusting lintels or inadequate support can present as growing cracks and sticking windows/doors, and may require builder or engineer attention.

Not always. In Canterbury, you’ll often see a mix of hairline plaster cracking from age and more concerning patterns like stepped cracking through brick mortar, widening diagonal cracks near openings, or separation between walls and ceilings. Our inspection looks at crack type, location and associated symptoms (uneven floors, roof spread, door binding) to determine whether the issue suggests structural movement and what further action is appropriate.
We focus on the building elements that carry loads and resist movement. That includes external walls, internal walls and ceilings, floors, subfloor structure (if accessible), roof framing in the roof space, visible beams/posts, and wet areas where moisture can damage structural timbers. We also assess site drainage around the home, as water management issues commonly contribute to movement and deterioration.
We can identify visible hazards and red flags that suggest non-compliant or risky work, such as unsafe penetrations, moisture impacts, or DIY alterations affecting structural members. However, formal compliance for electrical and plumbing is confirmed through appropriate licensed trades and documentation. If we see indicators of poor workmanship or risk, we’ll recommend targeted follow-up inspections or certificates before you proceed.
Renovations can increase risk when load-bearing walls are removed, openings are widened, or new levels/extensions add weight without adequate support. In Canterbury, it’s common to see older homes reconfigured for open-plan living, which can hide undersized beams, insufficient posts, or altered bracing. We look for signs of deflection, cracking, and inconsistent construction that indicate the structure may not be performing as intended.
We document the defect with photos, explain why it matters, and outline practical next steps. Depending on severity, that may include engaging a structural engineer for design advice, getting a builder to quote rectification, or arranging further invasive investigation to confirm the cause. We also help you understand what can be monitored versus what needs urgent action, so you can negotiate or plan repairs clearly.
