Older walk-up blocks across the Berea, Musgrave, Glenwood and Morningside run original galvanised risers that corrode from the inside. One flat reports a leak; the riser is failing for all of them.
For newer high-rise buildings see apartment leak detection. Full range at Leak Detection Durban.

- Galvanised risers feeding several flats off one vertical line, corroding internally after decades.
- Original cast iron waste stacks, rusting at the joints inside the duct.
- Bathrooms retiled over old membranes, or over none at all.
- Geysers in cupboards and voids, well past a normal service life.
- Roof and parapet leaks reaching top-floor flats.
Renting or Owning
A tenant is normally responsible for reporting a leak promptly and for damage they cause; the structure and its plumbing are the landlord's. Report in writing, keep the date, and photograph the damage before anything is moved. Delay is what shifts liability, since the landlord can argue the damage grew because it was not reported.

These are indicative market ranges, not a quotation. They are compiled from published South African leak detection and plumbing pricing to give you a starting point for budgeting. They are not the rate card of any company on this platform.
Where a galvanised riser has failed once, the rest of that line is at a similar stage. A block that keeps repairing sections is usually spending more than a planned replacement would cost.

Frequently Asked Questions
Who pays for a leak in a rented flat?
The plumbing and structure are normally the landlord's responsibility, and damage caused by a tenant's own negligence is the tenant's. Reporting promptly and in writing is what protects your position either way.
Is a flat leak different from an apartment leak?
The method is the same. Older walk-up blocks add corroded galvanised risers and cast iron stacks, which newer buildings do not have, and those are shared rather than confined to one unit.
My neighbour's flat is leaking into mine. What do I do?
Photograph the damage, report it to the trustees or managing agent in writing, and ask for a detection report. Do not open your ceiling until the source is confirmed.
