About DG Supplyline Ltd

DG Supplyline Ltd was established in 1999 as a subsidiary company of DG Servicing, a market leader in the double glazing repair and door maintenance industry. The company was founded in 1983 by Peter Guiver, whose vision and determination has taken the company right to the top of the industry. Specialising in undertaking the specialist repair of almost any type of door or window system, from a component part replacement to a complete frame repair. Having extensive knowledge in the business they began building up stocks of spare parts, especially unusual and hard to source commercial parts.

By using the knowledge & expertise gained through DG Servicing, DG Supplyline first started, by supplying specialised hardware to a national network of fitters, repairers, maintenance companies, locksmiths and other industry related companies.
