"Again, Charles and I want to thank you very much for handling this project so efficiently for us. We really appreciated you working with our tight timeframe - from the meeting in your office to coming out to the site and then getting the report to us, all in such a timely manner. I wish that all the other people I'm having to deal with on my claim were as responsive as you and your firm! I have already given your name to my lawyer and told him to recommend you whenever he can!!!" Private client, Orewa, Auckland
