Our comprehensive service includes everything you need to make an informed decision about your property.
We assess signs of footing movement through cracking patterns, brickwork separation, uneven floors and subfloor conditions. In Blackburn, movement can be worsened by moisture changes around the home, so we also look for contributing factors such as drainage fall, blocked vents and damp subfloor timbers.
We inspect internal and external walls for bowing, stepping cracks, racking and altered openings. This helps identify whether defects are cosmetic or linked to compromised structural elements, including cut or undersized framing from past renovations.
We check roof framing for sagging ridgelines, cracked or modified trusses, undersized members, and signs of long-term moisture. Roof space defects matter because they can indicate ongoing water ingress or structural overstress, not just a roof covering issue.
We look for leaks and moisture pathways that degrade structural materials over time, including around bathrooms, laundries, external cladding junctions and flashings. Where accessible, we identify rot risk, corrosion and deterioration that can lead to major defects if left unmanaged.
We assess brick veneer and masonry elements for bulging, separation and lintel distress above windows and doors. Lintel failure and wall movement can be costly in older Blackburn homes and may indicate broader footing or moisture issues.
Major defects often sit alongside unsafe or non-compliant work. We note obvious electrical and plumbing concerns that can impact structural areas (such as water damage from failed pipework, or hazardous wiring in roof spaces) and recommend the right licensed trades for follow-up.

In Blackburn we often see movement-related cracking associated with reactive clay soils, especially where drainage or landscaping changes affect moisture around footings. Older roof spaces can show sagging or altered framing from past repairs or extensions. Moisture damage is another driver, with leaks around bathrooms, roofs or flashings leading to timber rot and masonry deterioration if it’s been ongoing.
We look at the crack location, direction and width, plus related signs such as sticking doors, sloping floors, cornice separation and brickwork stepping. Cracks that reappear after patching, run through brickwork in a stepped pattern, or coincide with gaps at window/door frames can indicate movement. We explain the likely cause and when an engineer should be engaged.
Yes, where safe and accessible. The roof space and subfloor are key areas for identifying major structural issues such as damaged or modified framing, sag, termite-affected timbers, and moisture-driven deterioration. If access is limited due to low clearance, stored items or unsafe conditions, we’ll document the restriction and advise what further access or specialist inspection is needed.
They can, particularly where older homes have been opened up, walls removed, or new loads introduced without appropriate support. We pay close attention to junctions between the original dwelling and additions, changes to roof framing, and signs of differential movement. We also look for moisture issues from updated wet areas, as leaks can quickly affect structural elements behind new finishes.
We’ll outline the defect, its likely impact, and the priority for action. For significant movement, roof structural concerns, or compromised load-bearing elements, the next step is usually an assessment by a structural engineer and, where relevant, quotes from qualified builders. If moisture is driving the damage, we’ll also suggest investigating drainage, waterproofing or plumbing faults to prevent recurrence.
