Choosing the wrong plumber in Johannesburg can turn a small leak into a flooded ceiling and a disputed invoice. After 16 years of callouts across Sandton, Midrand and Northern Johannesburg, here are the nine checks that separate a professional from a chancer — before you let anyone touch your pipes.
1. Check they are PIRB-registered
The single most important check. A plumber registered with the Plumbing Industry Registration Board (PIRB) can issue a valid Plumbing Certificate of Compliance — and registration means they are accountable to a national body. If a plumber cannot give you a PIRB number, walk away.
2. Insist on a written quote before work starts
A professional assesses the problem and quotes in writing before lifting a spanner. "We'll see when we get in there" is how a R900 job becomes a R6,000 invoice. Every quote should itemise labour, parts and any reinstatement (tiles, screed) so there are no surprises.
3. Confirm they issue a Plumbing COC
For property transfers, insurance claims and any geyser work, you need a COC. Only a registered plumber can issue one. If geyser or compliance work is involved, the COC should be part of the quote — not an afterthought.
4. Check public liability insurance
If a plumber floods your home or a neighbour's unit, public liability cover is what pays for the damage. Ask directly. Uninsured "handyman plumbers" are cheap until something goes wrong.
5. Be wary of suspiciously cheap callouts
A R150 callout is bait. The real cost appears once they are on site and you are committed. Reputable plumbers charge a fair, transparent callout that is usually deducted from the final invoice if you proceed.
6. Ask who actually does the work
Many "plumbing companies" are call centres that dispatch whichever sub-contractor is free. With an owner-managed plumber you get the same accountable person each time. Ask: "Will the person who quotes be the person who does the work?"
7. Look for SABS-approved parts and a workmanship warranty
Cheap, non-approved fittings fail fast. A professional uses SABS-approved materials and backs the workmanship with a written warranty (we give three months). No warranty usually means no confidence in the work.
8. Read reviews — and check the dates
Look for recent Google reviews, not a single glowing testimonial from years ago. Patterns matter: do they show up on time, quote fairly and clean up? A plumber happy to share their Google profile is a good sign.
9. Make sure they actually serve your area
A plumber based an hour away will either decline your emergency or pad the callout for travel. Use someone who genuinely covers your suburb — we work across Sandton, Midrand, Fourways, Bryanston and the wider Northern Johannesburg area, six days a week.
The short version
PIRB-registered, insured, quotes in writing, issues a COC, uses approved parts, and serves your area. That is the whole checklist.
