Our Story, From Plumbing to Projects
Established in 2014, JSC Group & Co Pty Ltd began as a passion project born out of James Cassar’s successful plumbing business, JSC Plumbing.
With over two decades of plumbing experience and years of hands-on building expertise, James made a seamless transition into residential construction and development.
Starting with personal projects, he soon built a reputation for quality, trust, and hands-on project delivery. This laid the foundation for a full-scale construction company offering custom builds, renovations, extensions, and more. With every project, James brings a personal approach that prioritises client needs and project excellence.

At JSC Group & Co, our goal is simple to build homes and developments that reflect your lifestyle, while making the construction process seamless. James remains involved from consultation through to handover, offering clients consistent communication, on-site presence, and a high standard of craftsmanship.
Our commitment to honesty, professionalism, and attention to detail ensures each project runs smoothly and meets client expectations. Whether it’s a custom home or a multi-unit development, we bring the same care and dedication. The result is a trusted local building partner who delivers quality every time.
