24 May 2026 · Plumbers On Duty
Quick answer
| Type of burst | Repair time | Cost |
|---|---|---|
| Pinhole leak on visible copper | 30–60 mins | R900–R1,500 |
| Split copper pipe section in the wall | 1.5–3 hours | R1,500–R2,800 |
| Burst PEX in the ceiling | 2–4 hours | R1,800–R3,200 |
| Burst supply line under the lawn | 3–6 hours | R3,500–R8,000 |
| Burst supply line under the driveway | 6 hours – 2 days | R8,000–R25,000 |
| Geyser cylinder split (full replacement) | 4–6 hours | R12,000–R20,000 |
| Galvanised pipe corrosion (re-pipe a section) | 1–2 days | R8,000–R30,000 |
These are active repair times — total downtime is usually 1–2× longer once you include detection, drying out and reinstating.
Timeline of a typical repair
Minutes 0–60: Emergency response
- Plumber arrives, assesses
- Water isolated, system drained
- Damaged section identified
Hour 1–2: Excavation or access
For a visible pipe, this is almost nothing. For buried or in-wall:
- Chip out plaster (15–30 mins)
- Lift floor tiles (45–90 mins each)
- Dig down to a buried line (1–4 hours depending on depth and ground)
Hour 2–3: Replace pipe section
- Cut out damaged section (5 minutes)
- Solder copper joint (15 minutes per joint) or fit push-fit coupling (5 minutes)
- Pressure-test at 600kPa for 30 minutes
Hour 3–4: Reinstate
- Backfill trench or patch plaster (varies)
- Reseal tiles, repaint affected area
- Run system, confirm no leaks
Then: drying out
- Affected walls / floors / ceilings need 3–7 days with fans and a dehumidifier
- Paint and plaster can only be done once moisture content drops below 15%
What slows the job down
- Buried pipes — depth, ground conditions (rock, clay), proximity to other services
- Tile floors — every tile has to be lifted intact for reinstatement, or replaced
- Old galvanised pipes — corrode at threads, can crumble during removal, expanding the repair
- No isolation valves — plumber has to shut off at the meter, affecting the whole house all day
- Inaccessible spaces — geysers in low roof spaces, pipes behind cupboards
What you can do to speed it up
- Locate and label your main valve in advance
- Photograph the burst before turning the water off (helps the plumber and insurance)
- Clear furniture and access before the plumber arrives
- Have a second person at home to make tea, fetch buckets, accept materials delivery
- Authorise materials purchase up front so they don't have to wait on a quote
Cost difference: normal hours vs after-hours
The same repair done after hours adds R450–R1,200 to the bill in call-out and hourly premiums. If you can make the leak safe yourself (isolate water, catch drips), wait for normal hours.
After the repair: don't forget
- Insurance claim — most household policies cover the damage, not the pipe itself
- Drying out — 3–7 days with dehumidifier and fans
- Reinspection — get a Certificate of Compliance from the plumber, especially if your insurer asked
- Check the rest of the system — if one section of galvanised pipe burst, others are at risk
