Moisture & air supplies in Johannesburg: local notes

Winter air on the Reef is dry, so humidifiers for a baby's room or a dry bedroom sell here more than absorbers do. Moisture absorber tubs still earn their place in built-in cupboards, car boots and rarely opened rooms in older houses. Silica gel packs suit goods leaving through the City Deep container depot, and a cheap hygrometer will show whether a cold bedroom really is damp.

Johannesburg: the weather, the buildings and the damp

Johannesburg sits high and dry for most of the year, so damp here is local rather than general. It shows up in the old brick houses of Melville, Parkview and Observatory, where a failed damp-proof course lets moisture creep up the lower walls, and in cold south-facing bedrooms in winter. Inner-city blocks in Berea and Braamfontein, student digs and crowded rentals add condensation from washing dried indoors. Basement parking and storage under Rosebank and Sandton blocks can stay clammy after summer storms. Suppliers, hire firms and damp contractors are spread across the metro, with warehouse stock in the industrial belts south and east of the CBD.

Who asks for humidity meters around Johannesburg, most often first:

  • Landlords, agents and body corporates: meters in flats to show a tenant or an agent what the humidity really is
  • Warehouses, archives and storage: loggers in aisles and stores to record humidity and temperature over time
  • Offices, schools and clinics: meters in a records room or a server room to watch humidity

Local tips for Johannesburg

Asked for most in Johannesburg: mould removal in rentals, damp walls in old brick houses, archive and stock rooms. Where the suppliers are: industrial belts around City Deep, Jeppe and Wynberg, plus the northern suburbs. A useful tip: ask whether the inspector finds the source of the damp or only treats the stains.

Sizes vary: single room meters to multi-site loggers. Here, landlords, agents and body corporates lead the requests, typically for meters in flats to show a tenant or an agent what the humidity really is. One local point to raise: local firms cover the metro, longer drives to Soweto and the far north cost more.
