Melbourne homes range from Victorian terraces to post-war brick veneer and newer apartments—each can hide different major defects, from reactive clay movement to balcony waterproofing failures and ageing roof structures.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess crack type, location, and direction across plaster, masonry, and junctions to help distinguish typical shrinkage from movement that may indicate footing issues or ongoing settlement. This matters in Melbourne where reactive clay and variable site fill can drive seasonal movement that worsens without drainage and footing control.
We inspect accessible subfloors and supports for deterioration, termite damage indicators, inadequate bracing, moisture conditions, and uneven bearing. Major defects here can lead to sloping floors, cracking through the home, and costly rectification—especially in older raised timber homes and extensions.
We check roof framing, truss/rafter condition, signs of leaks, sarking issues, sagging ridgelines, and moisture staining. Melbourne’s storms and wind-driven rain can exploit small failures, and persistent roof leaks can turn into structural timber decay and electrical hazards over time.
We examine gutters, downpipes, overflow provisions, falls away from the building, weep holes, flashings, and damp-prone junctions. Poor stormwater control is a common trigger for footing movement and rising damp-like symptoms, so identifying water pathways is critical for major defect risk.
We look for evidence of membrane failure such as drummy tiles, cracked grout, ponding, swollen skirtings, and staining to ceilings below. Balcony and bathroom leaks are high-cost defects in Melbourne apartments and townhouses because damage can extend into structural elements and neighbouring lots.
We identify visible risk items like unsafe cabling in roof spaces, poorly supported plumbing, active leaks, and penetrations that may compromise fire-rated elements in multi-unit settings. While we don’t certify electrical or plumbing compliance, we flag issues that warrant licensed trade assessment before settlement.

A major defect is a problem that significantly affects structural integrity, safety, or weatherproofing—such as footing movement causing progressive cracking, roof leaks leading to timber decay, or failed balcony waterproofing damaging structural elements. In Melbourne apartments, major defects can also involve shared components like facade waterproofing, fire separation penetrations, and water ingress pathways that impact multiple lots and body corporate costs.
We assess the crack pattern, width, direction, and where it appears (openings, corners, brick courses, ceilings) and look for related signs like uneven floors, racked door frames, and external drainage issues. Some cracks are cosmetic, but stepped brick cracking, ongoing separation at joints, or multiple indicators together can suggest movement. If the risk is elevated, we’ll recommend a structural engineer for confirmation.
Yes, where safe and accessible. Roof spaces often reveal leaks, framing issues, and electrical hazards that aren’t visible from the living areas. Subfloors can show moisture conditions, stump or bearer problems, inadequate bracing, and other structural concerns that drive floor movement. If access is restricted, we note the limitation and explain what it means for defect risk and next steps.
Older Melbourne homes can show moisture-related issues from ageing guttering and poor stormwater discharge, subfloor dampness affecting timber supports, and cracking linked to reactive soils and drainage changes over time. Renovations can introduce their own defects too—such as removed walls without adequate support, poorly flashed additions, or bathrooms built over timber framing without correct waterproofing, leading to hidden decay.
Apartment purchases can involve building-wide defects that affect levies, special contributions, and ongoing maintenance. We focus on visible signs that may indicate broader issues—balcony drainage and waterproofing red flags, facade moisture entry points, staining in common-adjacent areas, and penetrations that could compromise fire separation. We also suggest what to check in strata records so you can confirm whether defects are known and budgeted for.
