What We Do


We are a proudly Australian cleaning services company who have been operating from our Sydney office in Mortlake since 1989. So you can rest assured we have many years experience of providing top-notch commercial cleaners. We are also taking a very hands-on approach to all of our contracts and believe that great communication is the key to a healthy relationship. We can do this in the least obtrusive manner possible, from picking up the keys after your people finish work to dropping them back to you along with the assurance of a sparkling clean workplace. We want you to barely notice our presence whilst we work and to just enjoy a great building cleaning service once we are done.

Our goal is to make sure you’re not unnecessarily involved with the process. We will take the management of the whole project large or small off your hands to deliver high quality cleaning every time. We will also make sure you’re happy with every single cleaning duty that is being performed and we make sure your premises are as clean as it can be. Not only this we also provide a full range of office cleaning services and solutions that include, vacuuming, dusting, taking out the rubbish, carpet steam cleaning and cleaning toilets, showers and sinks. We also pride ourselves on our use of Australian made PEFC certified cleaning products wherever possible.
