How to Find a Reliable Plumber in Johannesburg: 8-Point Checklist

Johannesburg's plumbing market is huge and unregulated at the entry level. Anyone with a bakkie and a pipe wrench can call themselves a plumber. Here's how to separate professionals from chancers.

The 8-point checklist

1. PIRB registration — only PIRB plumbers can legally issue a Certificate of Compliance (COC). Verify the number on our PIRB lookup.
2. IOPSA membership — voluntary but a good signal. Members carry liability cover and follow a code of conduct.
3. Physical address — a registered business address in Joburg, not just a cellphone number.
4. Public liability insurance — at least R5 million. Ask to see the policy.
5. Written quote before work — itemised, with VAT shown.
6. Reviews on multiple platforms — Google, Hello Peter, and directories like ours. Be wary of plumbers with only 5-star reviews and no detail.
7. Specialisation match — geyser specialists, drain specialists and bathroom renovators are not interchangeable.
8. Suburb knowledge — a Sandton plumber should know which estates require pre-approval; a Soweto plumber should know municipal pressure issues.

Red flags to walk away from

• "Cash only, no invoice."
• Refusing to give a surname or company registration number.
• A quote written on the back of a business card.
• Demanding more than 30% deposit upfront for a small job.
