JG Kelly Supplies Ltd, founded by the late Gerard Kelly, started with humble beginnings, utilising a Volkswagen pickup and borrowed storage space. As the business grew, new headquarters were established on Mall Road in Monaghan in December 1989. Specialising in uPVC building products, roofline fascia and soffit systems, the company quickly expanded its presence, particularly in the west and throughout the rest of Ireland.
In 1991, cellular and aluminium rainwater products were added to the hollow soffit and fascia range, and during the same year, J G Kelly Supplies entered into a partnership with the French plastic conglomerate, Grosfillex, to market and distribute their uPVC wall panelling in Ireland.
In January 1994, the Dublin Warehouse was opened, situated in the Western Industrial Estate on Naas Road. This depot provides installers with a convenient and improved service in the Greater Dublin area.
By 1997, J G Kelly was supplying customers across all thirty-two counties of Ireland. The product range had expanded to include prestigious offerings like Regency Rainwater systems and the Toffolo Expansion Joint/Screed for cost-effective concrete slab and industrial floor forming.
Due to high demand for the company's products, a new 5,000 sq. ft warehouse was acquired at Ballysimon Road, Limerick, in October 2000. This expansion aimed to enhance service for customers in the Munster Region.
