About Us
Our Story
Founded on the principles of hard work, integrity, and excellence, Demcon began as a small earthmoving operation with a simple mission: to provide reliable, professional excavation services to the Sydney region.
Over two decades, we've grown from a single excavator operation to a comprehensive construction services company, expanding our capabilities to include demolition, civil works, and site remediation.
What started as a commitment to quality earthworks has evolved into a trusted partnership with clients ranging from homeowners to major commercial developers and government agencies.
Our growth reflects not just our expanding fleet and capabilities, but our unwavering dedication to safety, precision, and client satisfaction. Every milestone in our journey – from obtaining our Class A & B Asbestos licenses to becoming a government-approved supplier – represents our commitment to meeting the highest industry standards.
Today, Demcon stands as a testament to what can be achieved through consistent quality, honest business practices, and a genuine care for the projects we undertake and the communities we serve.
