About CSI

CSI (Canberra Sydney Property Inspection) are specialist Building Consultants. University trained inspectors and consultants have served the Canberra and Sydney construction industry for thirty years, with consultancy for complex dispute resolution, building and pest analysis and expert witness services.

Due to the ever-changing building construction compliance environment, progressive computer analytical tools have been adapted to evaluate compliance regulations, structural and durability changes governing the built environment. This detailed analytical building evaluation for inspection reporting is essential in the modern era, to provide a complete picture for clients when purchasing,perhaps the most expensive undertaking in one’s life.

Evaluation of the property for purchase has two components. The first is the physical building development, the second is the land. These two components constitute the total value of the property. To make an informed decision on the value of the property, defects, significant or otherwise, have to be clearly identified. Our building and pest specialist consultancy provides the means to check the true value of the property. That is the obvious value buyers can see in the property they intend to purchase, minus the cost of rectification and repairs that our inspection experts investigate.

These repairs may be urgent or need monitoring. They may be structural or visual. Either way they need to be identified and considered in terms of the house or unit value. The bank will of course be pleased to know the “net value” too. If a house has hidden problems, such as non-compliance or worse still, termites, then if the purchaser is aware of these, they may be in a better position to “value” such a large contractual undertaking.

The most highly trained professionals should be entrusted with uncovering these hidden costs in a building purchase. Your solicitor will reaffirm the importance of undertaking an inspection report to reduce risk. Pre-purchase building inspections should only be performed by the best and most qualified inspectors using the latest and up to date regulatory compliance and investigative tools. This is why we use university trained inspectors. We have the best and latest computer report systems for on site and compliance evaluation. This technology also enables fast turn around of the inspection report within 24 hours. Our reporting system is a demonstration of current best practice. The professional, scientific, investigative evaluations, conducted by trained practitioners, eliminate the risk of failure of an otherwise good purchase due to hidden building repair costs.

Yours Sincerely,

Paul O’Donnell B Bldg (Hon) CSI Director

Thank you Louise for organizing all this work and to you Paul in conducting this Job. I will let my friends know about how great you guys are at CSI building and I will encourage them to call you when in need.
Thank you so much.



Hi Paul,

I just wanted to say a thank you for your help. I called quite a few places after a building & pest inspection that was needed urgently and from start to finish Louise was so lovely and very helpful. She kept me updated through every step of the booking, contacting the agent & tenant through to the confirmation.

You also called me after wards and gave me a very useful update so that I could go ahead with the exchange on the property. Not to mention the report that came though only hours later that night with colour photos and written so that we could understand it!

Thank you once again! I will defiantly be referring my family & friends onto you, please keep up the great work.

Kind regards,

Happy Customer – Charlotte

We obtained a pre-purchase report from Paul. Received the report the same day as inspection so we could put our offer in on time. Report was clear, had photos and diagrams to assist us. Easy to read and understand as a layperson

Amy Campbell


The best expert in Sydney is Paul. I have to go to the tribunal regularly and no other expert has done as good as work as Paul has.

It was a pre-purchase inspection. CSI actively chased the real estate agent to get access as soon as my request was received. The report is thorough. Paul called to discuss the results as soon as he completed the inspection. Such a lovely man and a delightful experience. Highly recommended.
