Building conditions in Johannesburg

Johannesburg has a huge stock of older homes in suburbs such as Melville, Parkhurst and Kensington, where renovations, extensions, new kitchens and bathrooms make up much of the building work. Many of these houses predate modern building regulations, so contractors often find damp, roof leaks and cracked walls to deal with. Rocky quartzite ridges in some suburbs make excavation slower, while clay soils elsewhere need well-designed foundations. Building plans are submitted to the City of Johannesburg, and heritage rules can apply to buildings older than 60 years. Summer hail and thunderstorms regularly damage roofs, and inner-city conversions add commercial and residential refurbishment work.

Townhouse complexes: body corporates waterproof flat roofs and walkways across several units at once
Shops and offices: shops and offices waterproof large flat roofs, box gutters and podium decks
Security and lifestyle estates: modern flat-roof homes need regular membrane checks and recoating to keep their guarantees
Warehouses and workshops: warehouses seal sheeted roofs, gutters and skylights to protect stock and machines

Frequently asked questions

What will my job cost in Johannesburg?

It depends on the size of the job, the site, the materials and finishes, and travel. Send the form with the details (plans or measurements help) and a waterproofing contractor working in Johannesburg will quote you.

Do I need plans or approval in Johannesburg?

New buildings, extensions and structural changes need plans approved by the local municipality that covers Johannesburg before work starts. Some small works are exempt. Your contractor or a draughtsman can tell you what applies to your job.

Small repairs can often start within days. Larger jobs depend on plan approval, material orders and the contractor's schedule. Ask for the start date and the expected duration in your quote.
