About SKG Services

SKG is one of Australia's leading providers of commercial cleaning, security, and property maintenance services.

We are a preferred provider to business and government organisations.

Established in 1977, SKG Services is an award winning, family-owned business which provides high quality commercial cleaning, security and maintenance services.

Our company's founders, Steve and Kathy Manoussakis, came separately to Australia as Greek immigrants in the 1960s. They met and married in Sydney and had their son, George, now our company's Managing Director, around five years later. Observing the overall poor quality and general under commitment of cleaning contractors back in the 1970s, Steve and Kathy took it upon themselves to raise the bar in commercial cleaning standards and client service. Their belief was that cleaning should not only deliver bottom line results, it should also create better experiences.

George, now with over 30 years of commercial cleaning experience, has held true to his parents' vision and taken SKG from strength to strength - nurturing it from a single office family cleaning business to well-built, values-based company that offers commercial cleaning, security, and property maintenance services from a network of offices across Australia and New Zealand.

From humble beginnings, we have grown to be a valued partner to businesses, all layers of government, and the region’s leading facility managers. Our client service is second to none and we are proud of our reputation for being one of our industry’s most reliable, helpful and respectful property services providers.
