About Mason and Brophy

Who we are

Mason and Brophy Strata Management has been servicing Sydney’s Northern Beaches for over 30 years, with cost-effective strata management solutions for residential, commercial and community schemes, as well as consultancy services for developers.

Mason and Brophy Strata Management was established in 1975 in response to the need for a personalised strata management service that puts the customer first. With that in mind, we set about to change the perception of strata management operators from those with purely a financial interest to those with an interest in people. At Mason and Brophy Strata Management, we pride ourselves on our ability to build strong customer relationships.

Our doctrine is to treat all customers with a personal touch while providing leading strata management solutions. This has been our biggest strength and continues to set us apart from other strata management companies.

“Mason and Brophy Strata Management has been managing our building for over 10 years. Being part of the strata committee for nearly 18 years, I have had the pleasure of dealing with our very friendly and kind strata manager Cathy Quattroville on a very regular basis. Cathy has been exemplary in her hardworking, professional approach to providing support and guidance when dealing with our strata issues. Calls and emails are always followed up, and Cathy acts immediately on all concerns that are brought to her attention, ensuring all strata committee members are included in the decision making for the complex. Furthermore, Cathy’s knowledge of strata laws and legislation is second to none.

Since Cathy has been our strata manager, there has been a dramatic improvement in the condition of our complex. Maintenance and repairs have been actioned, financial savings have been found with contractors, and any outstanding problems have always been resolved.┬áCathy is a credit to the industry and an absolute pleasure to deal with, and I would not hesitate to recommend her for any strata-related matters.”
