“Big thanks to Jake and Daniel from Grade A Plumbing for the great service. They helped replace our old toilet and also recommended new tap washers, which have made a huge difference. The whole job was done neatly, the bathroom was left clean, and everything was explained in a simple way. Really happy with the result. If you need a reliable local plumber for toilet installation, tap repairs, leaking taps or general plumbing work, I’d happily recommend Grade A Plumbing.”

“A blocked kitchen sink drain and a worn tap washer both needed attention,so getting them sorted in one visit was ideal. The plumber arrived right at the beginning of the scheduled service window, which we really appreciated. He was courteous, efficient,and completed both repairs without unnecessary delays. The final charge matched the estimate exactly, with no surprise fees or additional costs.The whole experience was professional, straightforward, and reasonably priced. We'd definitely call again for any future plumbing needs.”
“We called Grade A Plumbing Melbourne after discovering a leaking pipe beneath our kitchen sink at our home.The plumber quickly identified the cause of the leak, replaced the worn fittings, and checked the rest of the pipework to make sure there weren't any other issues.Everything was completed efficiently, the work area was left clean, and the whole process was explained clearly.It was a smooth experience from start to finish, and we'll definitely use Grade A Plumbing Melbourne again if we ever need a plumber.”

Plumbing service enquiries near Thornbury.
Search by official suburb/locality and postcode. Coverage is marked separately; new areas remain unconfirmed until checked.
Speak with Grade A Plumbing about blocked drains, leaks or hot water faults in Thornbury. Explain the immediate problem, previous work and access arrangements. For a planned drainage alteration, include the proposed changes so the enquiry can be assessed separately from a repair.
Prepare the proposed works description and site plan
Darebin's discharge application asks for a description of proposed building works and a site plan. For a Thornbury connection enquiry, these documents help distinguish an intended change from an assessment of an existing fault.
Council also directs applicants needing permission to connect to its road-opening permit process. Explain whether the scope may extend beyond the property boundary, and confirm the relevant process with Council. Do not treat an enquiry, connection recommendation or drainage clearance as permission to open a road or footpath.
For a Thornbury alteration enquiry, supply a sketch or existing site plan showing the intended work and any area outside the property that could be affected. For a repair, describe the fault history instead of treating a future design as the current diagnosis. Confirm what the assessment includes and what drawings or permission questions remain outstanding.
Authority information is general guidance, not a diagnosis or approval for your property.
Choose a listed locality and postcode. Unconfirmed locations can still be selected so the team can check coverage.
