Establishing a supply of suitable tools and conservation materials, insurance, accommodation, and transport all needed careful planning. In the twenty years during which Aagaard headed the organisation, Cathedral Camps enabled some nine thousand students to spend time working and living in cathedrals. Camps were organised every year at twenty-four centres, mostly English cathedrals, but also some larger parish churches and some Church of Scotland, free church, and Roman Catholic places of worship. Aagaard was a churchwarden at Knaresborough and from 1995 a member of the General Synod of the Church of England. He was Chairman of the Ripon Diocesan Advisory Committee and a member of the Ripon Cathedral Fabric Advisory Committee from 1993, a member of the Bradford Cathedral Fabric Advisory Committee from 1997, of the Cathedrals' Fabric Commission for England, from 1995, and of the Ripon Diocese Redundant Churches Uses Committee, from 1984. In 1960, Aagaard married Fiona Christine Drury, and they had two sons and one daughter. In "Who's Who", he gave his recreations as "Gardening, walking" and his address in the year of his death as Manor House, High Birstwith, Harrogate, North Yorkshire. Aagaard has an early place in any alphabetical list, and in May 2020 his entry in the combined index of "Who Was Who" was first out of 131,546 entries. Second came Professor Alvar Aalto.
