What Canberra
Customers Say About Us

No call centres. No missed bookings. Just real plumbing done right — here’s what locals think.

  • We had a great experience with Greaney & Sweeney installing our new Aerated Wastewater Treatment System. They gave clear advice, handled all the council paperwork, and did a neat, professional job. They even helped us troubleshoot another plumbing issue while they were here. Everyone we dealt with was friendly, helpful, and knew their stuff. Thanks!

    Sarah W.

  • Really genuine people. Glen always goes out of his way to help. The office girl is always pleasant and helpful. It’s great to have a tradie you can trust with great manners. Highly recommend.
