FAQs
What commercial plumbing services do you provide in Cowan?
Our commercial team covers the full spectrum of plumbing work your business might need, including new installations, pipework design, blocked drain clearing, CCTV inspections, hot-water plant repair or replacement, gas fitting, backflow prevention, thermostatic mixing valve (TMV) servicing, grease-trap installation and cleaning, roof and gutter repairs, and water-efficiency audits. Whether you operate a café, warehouse, office block or school, we can tailor a solution to your site’s specific requirements.
Are your plumbers licensed, insured and experienced with complex commercial systems?
Yes. Every plumber who attends your site holds a current NSW plumbing contractor licence as well as white-card safety certification and working-at-heights permits where required. Our company carries $20 million public liability and full workers-compensation cover. Just as importantly, our technicians work on commercial and industrial sites every day, so they understand large-bore pipework, pumped drainage, trade-waste systems and the compliance standards that govern them.
How fast can you respond to an emergency at my Cowan business?
We provide a genuine 24 / 7 emergency service. Because our depot is less than 15 minutes from Cowan, a fully stocked service vehicle can normally be on site within an hour of your call—often sooner for critical issues such as burst water mains or gas leaks. While in transit, our office will guide you through immediate shutdown procedures to minimise damage and downtime.
Will plumbing works disrupt my operations or customers?
Minimising interruption is a core part of our service. We can schedule works after hours, on weekends or during your planned shutdowns. If out-of-hours access is impossible, we isolate only the section being worked on so the rest of your building can keep trading. Dust screens, floor protection, safe pedestrian diversions and strict housekeeping mean staff and patrons can move through the area safely while we work.
Do you offer clear, upfront pricing and written quotes?
Absolutely. After a free site inspection we supply an itemised quote that explains labour, materials and any compliance testing in plain English. Unless the scope changes, the price you approve is the price you pay—no hidden call-out fees or weekend surcharges. If unforeseen issues arise we’ll always discuss options and obtain written approval before proceeding.
Can you provide ongoing maintenance and compliance testing for my property?
Yes. Many local businesses engage us on preventive maintenance agreements that cover routine inspections, valve servicing, backflow testing, grease-trap cleaning, TMV calibration, fire hose-reel flow tests and annual Condition Reports. Regular servicing not only extends the life of your assets but also keeps you compliant with NSW Health and Australian Standards, helping you avoid fines and unexpected shutdowns.
