"Finding the truth from their own words"
I specialise in examining expert reports to reveal what is supported, what is overstated, and what the evidence truly shows. Through structured technical and compliance review, I help the legal dispute process by revealing the truth based on the facts or lack thereof.
Common weaknesses Exredis uncovers in Expert Reports
When a client engages Exredis to review an expert report for a building dispute, NCAT matter, or building insurance claim, the report is examined with a focus on the subtle reliability issues that often go unnoticed until they are challenged.
The forensic assessment considers whether genuine independence has been maintained, whether the reasoning and causation analysis is grounded in sound engineering, and whether the factual basis — inspections, measurements, and evidence — is sufficient to support the conclusions.
The review also evaluates the correct application of standards, the boundaries of the expert’s discipline, the clarity and structure of the technical communication, and the defensibility of any rectification scope or costing.
Through this process, Exredis identifies the recurring weaknesses that frequently compromise expert evidence and cause a report to fall short of the standard expected by NCAT and the Courts in building and engineering disputes, including issues such as unsupported reasoning and advocacy‑style writing.
EXREDIS CORE SERVICES
1. Early Technical Case Assessment
Purpose: Early, simple identification of technical issues before committing to expert engagement or substantive casework.
What this includes:
Review of the client’s factual narrative, affidavit, or statement for technical accuracy, sequencing, and mechanism clarity
Identification of technical misunderstandings, contradictions, or gaps that may affect later expert engagement
Initial scan of technical issues which may relate to the HBA, SoPA, Contract, DBP Act, or ACL
Early procedural and evidentiary risks
Plain‑language explanation, to solicitor on record
Benefit: Helps solicitors and their clients save money, by deciding whether to proceed, settle, escalate, or continue and brief an expert.
2. Pre‑Expert Briefing Alignment
Purpose: Ensure the expert is briefed accurately, comprehensively, and in alignment with the technical issues in dispute.
What this includes:
• Identification of technical issues that may interact with the HBA, SoPA, Contract, DBP Act, or ACL
• Identification of applicable NCC and AS/NZS standards
• Examination of technical causation pathways
• Structured, standards‑aligned scope for expert engagement
Benefit: Prevents mis‑briefing, scope drift, and incomplete expert opinions; reduces expert costs; and ensures alignment between the solicitor’s legal theory and the technical evidence.
Compliance note: Any references to legislation are limited to identifying where technical issues may intersect with statutory frameworks. Legal advice, interpretation, and pleading decisions remain solely with the solicitor on record.
3. Forensic Dismantling of the Expert Report (Applicant or Respondent)
Purpose: Determine whether the expert report is technically sound, evidence‑based, procedurally compliant, and correct in its analysis of causation.
What this includes:
Revealing errors, unsupported assertions, contradictions, and inconsistencies
Assessing methodology and reasoning
Identifying the correct applicable building, construction, engineering, and procedural standards
Determining any departures, omissions, or failures to comply
Assessing whether the proper cause or causes were considered
Benefit: Identifies vulnerabilities before the other side does; avoids reliance on defective or non‑compliant expert evidence; informs whether a replacement expert is required.
NOTE: A severely deficient applicant’s expert report can remove the need for a respondant's expert report — the quickest win (and most satisfying) is showing their evidence has no weight, and cannot sustain the claim.
4. Technical Evidence Testing & Hearing Support
Purpose: Convert the technical findings from services 2 and 3 into structured, standards‑aligned material that supports counsel in preparing for mediation, directions hearings, and final hearing.
What this includes:
issue‑by‑issue analysis of the opposing expert’s technical reasoning
identification of gaps, unsupported assumptions, and standards inconsistencies
mapping of technical vulnerabilities in the expert’s methodology
raising technical questions that may assist counsel in testing the evidence
Benefit: Provides counsel with a clear understanding of the technical strengths and weaknesses in the expert evidence, supporting the development of case theory and hearing preparation.
All legal strategy, advocacy decisions, and cross‑examination remain solely the responsibility of the solicitor and counsel.
5. Residential Building - Legal Education
Purpose: Conduct CPD presentations for generalist solicitors, who want to better understand the legal framework around residential home building work in NSW.
Benefit: Solicitors can gain an understanding of the Home Building Act, Security of Payments Act and Design and Building Practitioners Act and how this legislation applies to protect their (homeowner) clients.
6. Technical Review – Insurance Repair Scopes
Purpose: Clear, independent review of an insurer’s repair scope to check whether it properly reflects the actual damage and the work reasonably needed to fix it.
What this includes:
Review of the insurer’s builder assessment or repair scope for accuracy, completeness, and whether the proposed work matches the real damage
Identification of missing items, unreasonable exclusions, or assumptions that don’t line up with how the damage actually occurred
Check of construction method, sequencing, and Building Code compliance issues that may affect the quality or safety of the repair
Correction of common misunderstandings (for example, when owners or builders believe they must provide three quotes, when the insurer’s scope limits repairs, settlement offers are very low)
Plain‑English explanation to the builder or homeowner about what is missing, what is reasonable, and what may need to be added before quoting or accepting an insurer decision
Benefit: Helps builders and homeowners understand whether the insurer’s scope or settlement amount is enough to repair the property properly and in line with Building Code requirements. This reduces the risk of under‑scoping, ensures the work can actually be completed to standard, and supports fair settlement discussions.
7. General Consumer Disputes – Evidence Analysis & Commentary
Clear, Structured Insight Through Evidence Review
Some consumer disputes benefit from simple, clear analysis of the available evidence. Because I work across factual investigation, reasoning analysis, and dispute frameworks, I can explain...
why an event or outcome is supported (or not supported) by the evidence,
whether an account is consistent, inconsistent, or unverifiable,
using structured comparison and objective reasoning, and
demonstrate this through clear, plain‑English commentary.
My approach involves:
reviewing all available evidence in a structured, neutral way
clear, plain‑English explanations of what the material shows
general legal education (not advice) to help parties understand the framework
I can assist people before they apply to NCAT, or after they receive a notice from NCAT, by helping them understand the evidence they have — or the evidence that has been presented to them.
This helps people resolve issues efficiently, without unnecessary conflict or confusion.

About the Principal
About the Principal
My name is Nick Kastoumis, I grew up in and am based in Sydney.
I am a civil/structural engineer with more than 24 years’ experience in technical, compliance, materials innovation, and client‑facing/training roles, and in early 2024, I was admitted as a solicitor of the Supreme Court of NSW.
I have worked in building and construction for over 40 years.
In the early 2000's I received my NSW Building Contractors Licence and contracted for a couple of years, but did not renew it as contracting was not for me.
In 2002, I began a career in geosynthetics, which are geotechnical materials. These specialty materials, are used as critical components in the civil, road, rail, environmental and mining sectors.
In 2009, I set up my own geosynthetic consultancy, working with major overseas manufacturer's helping them deliver their products and systems into the Oceania infrastructure market.
With Tier 1 and 2 consulting engineers - I developed and provided design specifications, detailed designs, MQA and costings
With Tier 1 and 2 Civil contractors - I developed onsite installation methodology, SWMS and installation training as well as construction CQA for these materials and systems.
Exredis was founded on a lifelong, unrelenting passion to uncover the truth—to understand it, embrace it, and bring it to the surface. As John 8:32 reminds us, “the truth will set you free.”
By combining this commitment to truth with my experience across engineering, construction, and law, I aim to contribute to the efficient administration of justice in building and engineering disputes. My focus is on promoting fair and equitable outcomes grounded in real truth, honesty, accountability, and fairness.
Truth is not always convenient, but when we discover it and embrace it, we can move forward and become better for the experience.
