Blackburn North has many mid-century brick veneer homes, renovations and mature trees—conditions that can hide footing movement, roof spread and wall cracking that only a structural-focused inspection will uncover.

Our comprehensive service includes everything you need to make an informed decision about your property.
We assess masonry and internal cracking for patterns linked to footing movement (step cracking, diagonal cracking from corners, separation at joins) and check whether cracks are active or likely historic. This matters because movement-related cracking can indicate inadequate support, moisture-driven soil change, or poor site drainage that may continue to worsen.
Where the subfloor is accessible, we inspect stumps, bearers and joists for signs of settlement, rotation, decay or inadequate support, and we look for unevenness that corresponds to internal floor levels. Subfloor issues can be a major structural defect because they affect load transfer and can make future rectification costly.
We check accessible roof spaces for sagging members, spread, cut or altered trusses/rafters, inadequate bracing, and evidence of long-term water ingress affecting structural timbers. In Blackburn North, older homes that have had ducted heating, skylights or renovations may have framing alterations that compromise roof stability.
We inspect load-bearing walls and openings for signs of lintel failure, brickwork distortion, and movement around doors and windows (binding, gaps, racking). This is critical because it can indicate structural load issues rather than cosmetic plaster cracking, particularly around widened openings from renovations.
We look for indicators that leaks have affected structural elements: swelling, softness, persistent moisture staining, and deformation around wet areas. Hidden leaks can lead to timber decay or subfloor deterioration and can also drive soil moisture changes near footings, contributing to movement.
We assess grading, downpipe discharge points, surface water paths and signs of ponding near the building. Poor stormwater control is a common contributor to footing movement and wall cracking because it changes ground moisture conditions around the home—often the trigger for ongoing structural defects.

Find answers to the most frequently asked questions about our inspection service.
In Blackburn North we often see movement-related cracking in brick veneer and internal plaster, uneven or springy floors where subfloor supports have settled, and roof framing concerns where older homes have been modified for heating, skylights or extensions. Mature trees and drainage changes can also influence footing movement. An inspection focuses on identifying whether these signs point to a major structural defect that requires specialist advice.
Yes. Many Melbourne suburbs, including Blackburn North, can experience soil movement as moisture levels change between wet winters and dry summers. If stormwater is not managed well, or if gardens and trees alter moisture around the footings, the building can move and crack. We look for defect patterns that match moisture-driven movement and check site drainage and moisture indicators to identify likely contributors.
Not always. Hairline plaster cracking can be from minor shrinkage or past repairs, but wider cracks, recurring cracks, or cracks that follow structural lines (around openings, corners, or through brickwork) can indicate movement. We assess crack width, location, pattern and associated symptoms such as sticking doors, sloping floors or separated cornices to determine whether it suggests a major structural concern.
Renovations can create problems if load-bearing walls are removed without adequate beams or posts, if lintels are undersized over widened openings, or if roof framing is cut for services without proper strengthening. Extensions can also settle differently from the original house if footings or drainage weren’t designed consistently. We look for signs of altered load paths, movement at junctions, and workmanship indicators that warrant further engineering review.
We document the defect, explain why it’s significant, and outline the most likely contributing factors (for example drainage, subfloor support, or roof framing alterations). We’ll recommend the appropriate next step, which may include a structural engineer’s assessment, targeted invasive investigation, or specialist trade quotes. This helps you negotiate, budget accurately, or decide whether the property in Blackburn North is a suitable purchase.
