About Adek Properties


Thank you for visiting our website.

ADEK has been in business for 45 years.

Greg Altona de Klerk is the registered Principal and Master Practitioner of ADEK. Accredited with the Estate Agents Affairs Board. Qualified as an auctioneer and accredited with the South African Institute of Auctioneers.

ADEK was originally started in Sandton, Johannesburg by my late Father Trevor, in 1972. After spending many years exploring the Southern African bushveld, I decided that it was time to join the family business in December of 1999. After 15 years of running the Cape office from Hermanus, we decided to get back to our roots in Gauteng in 2014. Exciting to be back! My passions are agricultural, wildlife, and auctioneering
