St Mary’s is a well-connected, thriving suburb that is about 45 kilometers west of the Sydney central business district, under the local government area of the City of Penrith. It borders Colyton, Oxley Park, Werrington, and North St Marys. It is also an important hub within Sydney’s western suburbs, drawing from its historic character, modern infrastructure, and good transportation access that includes the St Marys railway station, the Great Western Highway, and M4 Motorway for fast access to both Penrith and Parramatta. With the new Western Sydney Airport coming close to the region, St Marys also continues to see significant growth and development.
It comprises everything from brick homes to cottages converted from older ones to new townhouse developments. It’s also ideal for both families and professionals or investors. This may be anything from plumbing installations of hot water systems, blocked drains, gas fitting, pipe replacement to bathroom and kitchen renovations. Since the suburb contains a mix of houses whose ages span many decades, demand for maintenance plumbing is equally high as for new construction plumbing.
That’s where we come in. The Clean Plumber is your trusted St Marys plumber, proudly serving Western Sydney for over 30 years-from fixing leaks and clearing drains to installing hot water systems and complete plumbing fit-outs. Our prompt, reliable, and long-lasting solutions are available to every home and business.
With over 500 five-star reviews, our plumbers are fully licensed and insured. We offer a lifetime workmanship guarantee, and we stand behind our honest pricing, professional service, and dependable results.
