After successfully establishing the business, the timing was right for it to grow as it approached the new millennium. A second store followed in Cork in 1997 on Centre Park Road in the Marina near Páirc Uí Chaoimh. The company grew with new stores being added in Kilkenny (2000), Tralee (2001), Athlone (2003), Galway (2005), Nutgrove, Rathfarnham in Dublin (2013), Raheen, Limerick (2018) and on the Commons Road in Cork (2022). The last to open was the Blanchardstown store in Dublin (2023). Pat McDonnell Paints currently employs 150 staff across its ten Paint and Décor Stores.
