Our comprehensive service includes everything you need to make an informed decision about your property.
We assess cracking patterns in brickwork, plaster and external walls, check for stepped cracking, separation at junctions, and doors/windows that bind. These signs can indicate footing movement, failed lintels or altered load paths—major defects that can require engineering input and significant repairs.
Where there’s access, we inspect subfloor supports for deterioration, inadequate bearers/joists, moisture impact and signs of movement. In older homes, settlement or poor support modifications can cause uneven floors and progressive structural issues that are expensive to stabilise.
We check roof framing for sagging, spread, cut members, and water staining, then look for likely leak entry points such as flashings, valleys, gutters and penetrations. Roof leaks can drive major timber decay, mould risk and ceiling collapse hazards if left unchecked.
We look for signs that walls have been removed or modified without adequate support, including undersized beams, poor workmanship, cracking at beam ends, and patchwork in ceilings. Renovation defects can be serious in Windsor homes where open-plan conversions are common.
We assess bathrooms, laundries and kitchens for moisture-related major defects: swollen skirting, soft flooring, failed shower bases, and water staining around penetrations. Persistent leaks can lead to structural rot, termite risk and costly strip-outs.
While a detailed compliance certification is performed by licensed trades, we identify visible warning signs: unsafe cabling, improvised connections, unprotected penetrations, active leaks, and poor drainage falls. These indicators often signal broader non-compliant work that needs urgent specialist review.

Find answers to the most frequently asked questions about our inspection service.
A major building defect is typically an issue that affects structural integrity, safety, or the building’s ability to perform as intended. In Windsor homes, that often includes significant structural cracking from movement, failing supports in subfloors, roof leaks causing timber decay, and serious wet-area failures. We document the defect, explain likely causes, and outline the next steps, which may include a structural engineer or licensed trades.
Yes. We look for renovation red flags such as uneven floors, cracking at new openings, patched ceiling lines that suggest altered framing, and moisture patterns that don’t match surface finishes. While we can’t see through walls, we assess the visible evidence around junctions, roof space/subfloor (where accessible), and wet areas. If the signs suggest structural alteration issues, we recommend targeted follow-up investigations.
Yes. For apartments, we focus on defects within the lot and accessible common-area interfaces, such as balcony and window leak pathways, internal moisture damage, cracking, and safety concerns. We also note issues that may require checking the owners corporation records, like recurring water ingress, roof drainage problems, or façade movement. Access limitations can apply, so we explain what was and wasn’t accessible on the day.
They can be. Party walls and close boundaries can conceal water entry points and make movement-related cracking harder to interpret without context. Works next door can also influence cracking and drainage behaviour. During the inspection, we pay attention to cracking at wall junctions, dampness along boundary walls, and roof drainage arrangements. We’ll also suggest what to ask the vendor or owners corporation to clarify responsibility and history.
Use the findings to make a clear decision: negotiate the price, request repairs, budget for rectification, or walk away. For structural concerns, we often recommend a structural engineer to confirm cause and scope. For active leaks or safety risks, a licensed plumber or electrician may be needed urgently. We’ll explain which items are time-sensitive, which are progressive, and what evidence to gather before settlement.
