Terrain Surveys Ltd have carried out a first class service of locating a drain pipe under my garden. Particular praise must go to Gareth and Euan, the onsite operatives who performed a first class survey on an extremely hot day. Consideration and care was exercised in my and my neighbours garden. Praise must also go to Sue in the office. All requests and questions were quickly responded to. Thank you.
