Windsor's terrace rows keep us busy: original cast iron stacks on the back wall, old clay drains running under the building, and bathrooms renovated twice without touching the pipes behind them. We attend Windsor most weeks.
We're a small team of BPC-licensed plumbers and Type-A endorsed gasfitters. Every Windsor job gets a fixed-price quote in writing before work starts, and a Compliance Certificate where one's required.

The Windsor callouts that keep coming back:









Alister Williams is the licensed plumber behind Prime Plumbing & Gasfitting. He holds a current BPC licence (No. 103414) and a Victorian Type A gasfitter endorsement, the tickets required for consumer gas appliance work in Victoria. Alister attends or supervises every Windsor job himself; there is no call-centre layer between you and the person doing the work. The Windsor call we get most is Windsor terrace owner or landlord dealing with a failing cast iron stack, older drain blockage under the building, a tenanted-property repair, or an older bathroom refurbishment. Every job in City of Stonnington ends with the BPC licence number on the quote, invoice and Compliance Certificate, so the record is verifiable end to end if your insurer or conveyancer ever asks.
