Our Clients

"Illawarra Progas, under Mathew’s leadership, did an excellent job completing the full gas reticulation works at our new Prestons site. Despite very tight timeframes and the need to coordinate with multiple vendors, Mathew and his team executed the project seamlessly. Mathew’s recommendation of the right gauges, the high standard of piping work, and his deep knowledge in the gas and reticulation space were invaluable. Not only was the cost reasonable, but he also provided guidance on various gas-related issues beyond the original scope. I truly appreciate Illawarra Progas Solutions' professionalism and expertise throughout the project"
