Suppliers and contractors on our network work in all nine provinces, from damp Victorian semis in Cape Town and humid seaside flats in Durban, to warehouses along the N3 and in Midrand, cold stores in the Boland, mines and power stations in Mpumalanga, and homes on the dry Highveld where the damp comes from a burst geyser or a storm leak. Choose your province or town to read about damp there and request quotes.
Gauteng
Gauteng is dry for most of the year, so damp here is usually a local problem rather than a climate one. Winter mornings on the Highveld are cold, and unheated bedrooms, north-facing garages and bathrooms without extractor fans collect condensation and black mould in the corners. Summer thunderstorms then find the weak spots: flat roofs, parapets and old brick walls in Parktown, Melville, Observatory and Pretoria's older suburbs. The province also holds the country's densest cluster of warehouses, archives, pharmaceutical stores and food plants, from Midrand and Kempton Park to Germiston and Waltloo, where humidity control is a business matter. Most suppliers and hire firms are based around Johannesburg and Pretoria.

Mpumalanga
Mpumalanga has two climates side by side. The Lowveld around Mbombela, White River, Hazyview and Barberton is hot and humid in summer, with heavy rain, and cupboards, shoes and leather go musty if a house is shut up for weeks. Up on the Highveld escarpment, Graskop, Dullstroom and Ermelo are cold and misty in winter, and stone and brick cottages stay damp for months. Coal country around eMalahleni, Middelburg and Secunda adds workshops, plants and stores where steel rusts and electrical gear needs dry air. Citrus, subtropical fruit and timber also make cold stores and packhouses a steady source of work for humidity control.
North West
North West is mostly flat bushveld and farmland with low winter rainfall, so outdoor damp is not the issue. Trouble comes indoors: cold, unheated rooms in Mahikeng and Lichtenburg where breath and showers condense on outside walls, summer storms that find leaks in flat roofs and old tin, and the dams around Hartbeespoort and Brits, where holiday homes stand shut for weeks and go musty. Rustenburg's platinum belt and Klerksdorp's mining and engineering firms use workshops, stores and electrical rooms that need dry air, and maize and sunflower silos on the western plains want moisture control for stored grain. Suppliers are mostly in Rustenburg, Klerksdorp and Potchefstroom, with a lot of stock coming from Gauteng.
Limpopo
Limpopo runs from the cool plateau around Polokwane to the hot, humid summer lowveld of Tzaneen, Phalaborwa and Thohoyandou. Around Tzaneen and the Soutpansberg slopes, mist and heavy summer rain keep tropical fruit farms green and make walls, cupboards and leather goods damp. Polokwane is drier, with cold winter mornings and condensation in bathrooms and bedrooms. Mining at Mokopane, Lephalale and Phalaborwa adds workshops and stores, and game lodges around Hoedspruit and the Waterberg have kitchens, shower blocks and linen stores that grow mould in the rainy months. Supply comes mainly from Polokwane and Tzaneen, with large items sent up from Gauteng.
Northern Cape
The Northern Cape is South Africa's driest province, a land of Karoo scrub, red Kalahari dunes and mining towns, and most of it has little outdoor damp. Here a humidifier is often more useful than a dehumidifier, because winter air can leave skin, noses and wooden furniture dry. Damp still shows up indoors: bathrooms without extractor fans, cold rooms in Kimberley and De Aar on frosty mornings, burst geysers, and rare heavy rain that finds a weak roof. Iron ore and manganese operations around Kathu, Postmasburg and Sishen need dry stores for electrical and spare parts, and the Orange River table grape sheds near Upington use cold rooms and packing halls with humidity control.
Free State
The Free State is wide open grassland, wheat and maize country, with cold dry winters that regularly drop below freezing and thunderstorms in summer. Outdoor damp is not the main issue, but the cold is: sandstone farmhouses and older homes in Bloemfontein, Kroonstad and Bethlehem keep rooms unheated, so breath, showers and drying washing condense on outside walls. The eastern highlands around Clarens, Harrismith and Ficksburg are wetter and mistier, and snow and rain leak through old roofs. Grain silos, seed stores and food plants need dry stock, while Welkom and Sasolburg add industrial plant rooms and stores. Local suppliers are mostly in Bloemfontein.
KwaZulu-Natal
KwaZulu-Natal is the most humid province, and the coast from Port Shepstone through Durban and Umhlanga to Ballito and Richards Bay is warm and damp for much of the year, peaking in the summer months. Mould shows up on cupboards, shoes, leather, bathroom ceilings and the underside of mattresses in beachfront flats and older homes in Morningside, Berea and Glenwood. Inland, Pietermaritzburg and the Midlands are cooler and misty, with cold, wet houses in winter. Durban's port, the Richards Bay terminals, sugar mills, food plants and logistics parks around Pinetown and Cato Ridge make industrial humidity a daily concern, and many suppliers and hire firms are based in Durban.
Eastern Cape
The Eastern Cape coast is mild and damp: Gqeberha, Jeffreys Bay, Port Alfred and East London get sea mist, drizzle and a south-westerly wind, and older homes in Walmer, Summerstrand, Southernwood and Berea often have limited ventilation, so washing dries slowly and cupboards smell musty. Inland the Karoo around Graaff-Reinet and Cradock is dry, with cold winter nights, while the Wild Coast and the hills around Mthatha get heavy summer rain, and rural homes and RDP houses struggle with condensation. Port Elizabeth's motor industry, the Coega zone, the East London port and citrus packhouses in the Gamtoos and Sundays River valleys need steady humidity control.
Western Cape
The Western Cape has wet, cool winters from about May to August, and that is when damp surfaces. Victorian and Edwardian semis in Woodstock, Observatory, Kalk Bay and the southern suburbs, brick homes on the Cape Flats, sectional title flats in Sea Point and bungalows along the Garden Route from Knysna and George all struggle with condensation, mould on bedroom walls and washing that will not dry. The south-easter blows dry in summer, but winter north-westers bring rain. The Winelands around Stellenbosch, Paarl and Worcester run cellars, cold stores and packhouses, and Cape Town's port and industrial areas such as Epping, Montague Gardens and Atlantis hold large warehouses.
