How we support your case
We provide independent testing and expert opinion to clarify installation, performance and failure issues. Our findings support fair outcomes for homeowners, insurers and legal matters through clear, defensible evidence.
Independent testing and expert assessment
We replicate and assess real-world installations to check whether products were installed correctly and to help identify the root cause of failures or disputes. Using recognised methods and realistic conditions, we deliver clear, defensible findings you can act on.
Where required, our experts can also visit site to assess installations, materials and structures in situ.
