In the middle of the twentieth century, structural issues began to plague the building and a portal frame was erected to support the dome. The congregation launched an appeal for £40,000 in January 1960. Despite the appeal's success, the extent of dry rot in the building soon became apparent and the congregation entered into negotiations for union with St Andrew's. The charges were linked with a single minister in June 1962 and formal union was completed on 7 June 1964. At the time of its closure, the church maintained halls and a church officer's house at Randolph Place. The manse was at 17 Wester Coates Crescent, having been at 3 Melville Crescent before 1946.Dunlop 1988, p. 127.
