Greg and team help me with storm water OSD system/civil plumbing system installation as per council requirements as part of a swimming pool construction. Greg's work has been extremely helpful, professional. To start with, the design of the storm water OSD system, by a separate hydraulic engineer, was an extremely challenging one. To meet all council requirements, the I.L, S.L of the pipe connections has to be as accurate as within 10mm. This is extremely difficult to achieve onsite. Greg worked closely with the inspector, measured all the R.L of all pipe connections, and in the end, the levels

Greg and the team at GSM Plumbing pulled off a miracle with our stormwater plumbing. After another contractor botched our stormwater connection, council blocked our subdivision certificate. We were extremely worried that wed have to rip up all of our stormwater drainage and start again, but Greg and his boys were able to sort it out, and worked overtime to help us get the job done before the COVID shutdown for construction. Were extremely grateful to have found them, and can absolutely recommend GSM Plumbing for all drainage and OSD work.

I am delighted to provide this review! Greg and his team from GSM have done a fantastic job at my house very recently. They installed gas and gas plumbing and also fixed a pretty complicated storm water issue which required approval from the council which Greg and his office handled completely. Greg was always prompt, punctual and was reachable on the phone. Greg's pricings are very reasonable for the quality of work he delivers. Best of all, he takes time to listen to the customer and provide well thought out solutions weighing in cost-benefit realisations. I have been super impressed by his hard
