The origins of C.A. Duquemin Ltd go back to 1924 when Alfred J Duquemin started in business as a stonemason and builder. Only two years later, he was commissioned to construct the Island War Memorial, showcasing premium craftsmen since our inception.
By 1930 the business had more than 30 full-time staff. Cecil Alfred Duquemin joined his father as a carpenter during the early 1930s and eventually took over the business and changed its name to C.A. Duquemin Ltd upon his father’s death in 1938.
The business remains in family ownership to this day.
For almost 100 years we have been paving the way for premium construction in Guernsey.
