Company History

GJ&K originated from a family company in 1985 whose names were George, John & Kerry, and offered a wide range of commercial cleaning services.

After operating from premises in Richmond for five years, in 1990 the company moved to larger premises in Hawthorn. Subsequently, in 1998, due to the company expansion, GJK purchased more appropriate premises in Rowville incorporating increased warehouse space. With the continued growth it has led us to seek larger and better premises and GJK now operates from their corporate offices located in Collingwood.

Today GJK have the systems and the scale to manage some of the most complex property management projects in Australia.


Executive Statement

Customer Satisfaction is the key focus of GJK Facility Services. All our actions in organisational development, staff motivation, management of our human resources, design and implementation of our operational procedures reflect and support this focus.

Our approach is to establish a culture in which both teamwork and individual excellence are encouraged through respect for and recognition of team members’ specialised skills and professionalism. This is enhanced by combining understanding, commitment and ownership of the service we deliver to our customers.

GJK Facility Services are the first to implement an externally audited Integrated Management System (IMS) within our industry. The system comprises Quality Accreditation AS/NZS ISO 9001:2008, Occupational Health & Safety AS/NZS 4801:2001 and Environmental Management Standards under AS/NZS ISO 14001:2004. The management tools for our service performance outcomes are now predictable and sustainable.

Our qualified Internal/External Auditors actively seek feedback on a regular basis from our Customers’ Representatives. The objective supported by our IMS Procedures is to further put into practice a proactive approach in ensuring customer satisfaction is continuously maintained.
