‘Fantastic service. We booked another damp surveyor who visited and gave very big but vague estimates about the work. To get a second opinion, we went to preservation treatments, the service could not have been better. They gave an honest recommendation about the work needed (or not). Great, honest service.’Damp Survey, Petersfield, Ben – 6th July 2017
