“Thank you for the survey which was very detailed and informative”.

“Throughout I found David to be friendly, helpful, knowledgeable and very competent. He was content for me to witness the survey and willing to explain and discuss matters there and then. I have no hesitation recommending him for survey work and intend to use him again when the time comes.”
