About Us

Founded in 2015 by long-time industry experts Lukas Calleja and Daniel Doran, True Seal was built on a single, unwavering mission: to create a Passive Fire Protection business that Tier 1 builders and facility managers can trust completely.
In an industry often complicated by changing regulations, we strip away the uncertainty. We don’t cut corners, and we don’t rely on guesswork. We provide dependable, certified fire protection done right the first time.
Today, our team brings together more than 140 years of combined experience keeping buildings safe and compliant across Queensland, New South Wales, and Victoria. We know the Australian Standards (including AS1530.4 and AS4072.1) front-to-back, and we stay in stride with every NCC update so our clients never have to worry about liability or safety risks.
