The story
After an apprenticeship as a plasterer and at the age of 22, John Sisk set up the construction business in 1859.
In April 2019, Sisk was removed from the UK Government's Prompt Payment Code for failing to pay suppliers on time. It was reinstated around 10 months later.
The company relocated 200 of its employees into its newly retrofitted head office at Citywest in Dublin in July 2024.
