Family values, professional pride and a relentless eye for detail — since 2019.
Founded in 2019 by Coen Sunderland and named for his father, Rhett — a man known for doing every job right the first time. Coen grew up working alongside him, and that standard is now the business.
After more than a decade in cleaning and construction, Coen built Rhett & Sons to raise the bar for exterior cleaning in South Australia: premium service, personal values and genuine respect for every property — from luxury homes to recurring commercial contracts.
