Our comprehensive service includes everything you need to make an informed decision about your property.
We check for signs of footing movement, differential settlement, cracked masonry, distorted openings, sloping floors, and past patch repairs. This helps identify whether movement is historic, active, or likely to worsen, and whether it may affect structural safety or require engineering input.
For homes with subfloors, we assess stump condition, bearers and joists, dampness, ventilation, and termite risk indicators that can contribute to major defects. Poor re-stumping and moisture-related timber deterioration can lead to bouncing floors, cracking, and long-term structural instability.
We inspect roof framing (where accessible), roof cladding, flashings, valleys, gutters, and penetrations for defect patterns linked to leaks and timber decay. Roof leaks are a common trigger for ceiling collapse risk, mould growth, and progressive structural damage.
We assess internal and external wall cracking, brickwork articulation, bulging, and lintel performance above openings. The goal is to distinguish cosmetic cracking from defect patterns consistent with movement, corrosion, or inadequate support.
Bathrooms, laundries and kitchens are checked for swelling, drummy tiles, failed seals, moisture staining, and ventilation issues. Waterproofing failures can cause concealed rot, mould, and damage to adjoining walls and floors—often presenting as a major defect once the surface finishes are removed.
We look for visible safety concerns such as DIY wiring, damaged cabling, unsafe power points, old or non-compliant installations, and plumbing leaks that drive ongoing moisture damage. While not a full compliance certification, this highlights defects that warrant urgent licensed trade review.

Find answers to the most frequently asked questions about our inspection service.
In Preston, we often see defect patterns tied to older construction and mixed-quality renovations. Common major issues include movement-related cracking, uneven floors from stump or bearer problems, roof leaks causing ceiling and wall damage, and wet area waterproofing failures. We also regularly find safety hazards from DIY electrical work or deteriorated wiring. Our inspection focuses on accessible evidence that indicates serious risk and likely repair pathways.
Yes—where access allows. We look for signs of footing movement (cracks, distortion, sloping floors) and inspect the subfloor for stump condition, moisture, ventilation, and timber deterioration. If access is limited, we document restrictions and rely on internal and external indicators to assess risk. Where findings suggest structural concerns, we’ll recommend the right next step, such as an engineer or re-stumping specialist.
We assess crack location, width, direction, and surrounding signs such as door/window binding, out-of-square frames, and stepped cracking in masonry. Cosmetic cracks are often limited to plaster shrinkage or minor surface movement, while structural patterns may indicate settlement, heave, or inadequate support. We’ll explain the likely cause based on observed evidence and advise when the crack behaviour warrants urgent investigation.
They can. In Preston, renovated interiors and rear extensions sometimes conceal removed or altered load-bearing walls, undersized lintels, uneven re-stumping, or roof junction leaks where old meets new. Bathrooms and laundries are also commonly updated, and poor waterproofing can be hidden until damage becomes extensive. We pay close attention to transition points, floor level changes, and signs of patching that may indicate concealed structural or moisture defects.
We document the defect clearly, explain why it matters, and outline the likely implications—safety, structural stability, or repair cost risk. We’ll also recommend practical next steps, such as further invasive investigation, a structural engineer’s assessment, or licensed electrical/plumbing review. If you’re purchasing, this information helps you decide whether to proceed, renegotiate, or request repairs before settlement.
