The Process

Project Details & Quote

The process begins when you send us your project plans and requirements. We review the details and provide a clear, comprehensive quote that covers all phases of the work ahead. Our aim is to offer a reliable cost outline upfront to keep your budgeting straightforward.

Once approved, our team moves swiftly into action. Our skilled plumbers coordinate each stage seamlessly with other trades on-site, whether it’s a large-scale project or a custom fit-out. We handle all plumbing phases with precision and efficiency, staying on schedule and keeping you informed every step of the way.


Inspections & Compliance

We arrange inspections with the Department of Fair Trading at key phases of the project, ensuring that all work meets industry regulations and safety standards. This keeps the project on track and compliant from start to finish.

After final checks, we conduct a thorough review with your team to ensure all work aligns with your specifications and our high standards. Our after-sales support is readily available to address any needs, making your experience with us smooth and dependable.
