About GMG

GMG Contractors Ltd. is a family-owned construction and contracting company. Incorporated in 1987, the company has evolved from a slating and plastering sub-contractor to a multi-trade main contractor with a growing turnover and extensive repeat business. Operating from a main site in Baillieston and a recently acquired satellite yard in Cumbernauld, GMG’s clients include premier private house builders, national construction companies, local authorities and housing associations.

GMG directly employ over 100 people – 40% apprentices and 60% trades, office and managerial staff – alongside around 70 self-employed contractors. Our recruitment policy deliberately balances experienced trades with apprentices, producing an average workforce age of 23 – one of the youngest in their sector.
