Blackburn South has plenty of mid-century homes and renovated weatherboards on reactive clay soils—movement, roof framing stress and subfloor moisture can hide until the damage is costly.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check for tell-tale signs of footing movement such as stepped brick cracking, widening plaster cracks, sloping floors, gaps at skirtings, and distortion around windows and doors. These symptoms help identify whether movement is historic, ongoing, or linked to moisture and drainage problems that need urgent attention.
For homes with subfloors, we assess stumps/piers, ant caps, bearer and joist condition, and signs of compression or rotation. We also look for inadequate ventilation and moisture sources that can weaken timber and cause structural deflection over time.
We inspect the roof space (where safe and accessible) for sagging or altered trusses/rafters, cut members from renovations, inadequate bracing, and signs of long-term leaks affecting structural timbers. Roof structure issues can indicate broader movement or previous modifications that compromise load transfer.
We differentiate between typical settlement cracks and cracking patterns more consistent with structural stress, including diagonal cracking from corners, separation at wall junctions, and movement around lintels. We also check for bulging walls and mortar deterioration that may indicate instability.
We target areas that commonly feed major defects: failed flashings, roof penetrations, wet areas, balcony junctions, and poorly graded ground levels. Persistent moisture can lead to timber decay, corrosion, and progressive weakening of critical structural elements.
We note structural safety concerns such as unstable verandahs, compromised decks, deteriorated retaining walls, and signs of unapproved or poorly executed alterations. We also flag visible plumbing and electrical issues that may contribute to moisture ingress or fire risk around structural cavities.

In Blackburn South we often see movement-related cracking in brick veneer, subfloor issues in older weatherboards (stump movement, bearer/joist deflection), and roof structure concerns after renovations where members have been altered. Moisture is a frequent contributor—blocked stormwater, poor surface drainage and older wet areas can accelerate timber decay and corrosion, turning minor defects into structural problems.
We assess crack location, direction, width, and associated symptoms. Diagonal cracks from openings, stepped cracking through brickwork, separation at wall junctions, and cracks paired with door/window binding can indicate structural movement. Hairline plaster cracks in predictable shrinkage areas may be cosmetic. We also look for related signs like uneven floors, roofline changes, and moisture that may be driving ongoing movement.
Yes, where safe and accessible. Roof spaces help us detect sagging members, leak-related timber damage, and changes from renovations that affect load paths. Subfloors can reveal stump condition, inadequate ventilation, moisture sources, and timber decay that impacts floor stability. If access is restricted or unsafe, we document the limitation and recommend the most practical next step to verify the risk.
They can be, particularly where old and new structures meet. In Blackburn South it’s common to see rear extensions, open-plan conversions and reroofing, and defects can occur if load-bearing walls were altered without adequate support, or if new footings perform differently to existing ones. We focus on junction points, roof framing modifications, and cracking patterns that suggest differential movement or overstressed members.
We’ll explain the likely cause, the level of concern, and what action is sensible. For significant movement, compromised roof framing, or unstable elements, we may recommend a structural engineer to confirm scope and design a repair. Where moisture or drainage is contributing, we’ll suggest targeted checks by a roofer, plumber or drainage specialist. You can then price repairs, negotiate, or reconsider the purchase.
