Independent building investigation for Sydney strata and commercial buildings — invasive testing that finds the real defect before a cent is committed to repairs. Don't guess. Know.
No obligation. A builder reviews it — not a call centre.





An investigation finds which layer failed and why — the diagnosis that has to come before a repair is priced.
Skip it and you pay twice: misdiagnosed repairs, scope blowouts, and rejected insurance claims with no documented evidence.
A report runs $1,500–$3,500 for a single area, $4,000–$10,000+ for a multi-area strata building — and rolls into the works.
Rushing past the investigation stage is the single most expensive mistake an owners corporation makes. Here's what it costs.
Cracks get patched while the waterproofing keeps failing. Concrete gets coated while corrosion continues underneath. The symptom is treated, the cause isn't — and the defect comes straight back.
A small leak left undiagnosed becomes a full facade or balcony rebuild. Caught early on a report, it's a contained repair. Caught late, it's a capital works programme.
In a dispute or claim, the absence of a documented investigation is a liability. Insurers reject claims without evidence; defect cases get harder to defend. A report is the evidence base.
A building investigation is the diagnosis that comes before the repair — finding which layer failed and why, not just what you can see.
Water ingress, cracking, corrosion and cladding failure rarely start at the surface.
By the time the stain shows on the ceiling, the cause is usually a layer underneath — a perished membrane, carbonated concrete, movement at a junction, or a detailing failure built in years ago.
"A price written without an investigation is a guess — it either pads for the unknown or misses it, and the owners corporation pays for the gap later."

We match the method to the defect — not a blanket checklist. A typical investigation draws on:
• Moisture mapping & thermal imaging — hidden water ingress behind facades, slabs and wet areas
• Concrete carbonation & core sampling — how far corrosion has advanced; cosmetic vs structural
• Borescope & internal cavity inspection — the failed layer without demolishing the element
• Leak detection & water testing — the exact entry path, confirmed not assumed
• Drone facade & roof survey — defects mapped with no scaffold or EWP
Each method is matched to the defect and the building — an observation report, a condition assessment, or a full invasive investigation.
A price written without an investigation is a guess — it either pads for the unknown or misses it, and the owners corporation pays for the gap as a variation later. A defined defect means a fixed-price scope, fewer engineer call-outs, and no repeat repairs two years on.
We're the builders who do the repairs — so our diagnosis is grounded in what we actually find when concrete is broken out and balconies are opened, not desktop guesswork. We're Class 2 DBP registered (Licence 360636C), and where works follow, the report rolls straight into the scope so nothing is wasted.
We'd rather you verify us than take our word for it. Our licence is on the NSW Fair Trading register — check it before you call.
A report is only worth what it can stand behind. Ours is built to survive an engineer's review, an insurer's scrutiny, and a tribunal's questions.
