The firm was successful, owing in part to a real estate boom at the time, and in 1888, Ramsay built the family a mansion at Essendon, which he named "Clydebank", after the Scottish town.
After the boom ended, Ramsay worked as a valuer for the City councils of Melbourne and Essendon, and the State Savings Bank of Victoria.
When William's Kiwi shoe polish began to take off in Australia, Ramsay travelled to England to promote the brand in the United Kingdom, establishing a branch of Kiwi Polish Co. in London.
Following William's death in 1914, and the subsequent amalgamation of the British and Australian branches of the company (as "Kiwi Polish Co Pty Ltd") in 1916, Ramsay acted as Chairman of Directors until his death on 3 March 1924, at Clydebank.
Ramsay was a deeply religious man, and acted as a lay preacher in the Congregational church.
