Dehumidifier.co.za is a free quote service for dehumidifiers, moisture control supplies and damp and mould services in South Africa. Whether it is a damp bedroom in a wet Cape winter, a mouldy bathroom in a humid Durban flat, a warehouse that must stay dry, or a house to dry out after a burst geyser, one request reaches the suppliers, technicians and contractors near you.

How it works

Fill in the job card at the bottom of the page. For a dehumidifier, a purifier, a mould job or drying out, give the room's length, width and ceiling height and how damp it is, and it works out the floor area and volume, suggests a size in litres a day and draws the room. For tubs, packs, meters, hire days or metres of wall, just say how many. We send your request to suppliers and contractors who work in your area, and they quote you directly. It costs you nothing.

Everything we take requests for

From a quiet unit for a damp bedroom in Cape Town's southern suburbs, moisture absorbers for every cupboard in a Durban beachfront flat and a humidifier for a baby's room in a dry Pretoria winter, to an industrial unit for a Midrand warehouse, a desiccant dryer for a cold store in Paarl, a pool hall dehumidifier for a gym in Sandton, mould removal in a rental block in Sea Point, rising damp treated in an old house in Gqeberha, or a house dried out after a burst geyser in Bloemfontein.

Getting quotes you can compare

Two quotes for "a dehumidifier" can be very different machines. Say where the damp is, the size of the space, how warm it gets, and whether you want to buy, hire or have the problem fixed. Then check that each quote states the capacity in litres a day and the test conditions, the power draw, the tank size or drain option, the noise level, the warranty and who services it. For contractors, check that the quote names the cause of the damp, what will be removed or treated, the guarantee and whether a follow-up visit is included.

Frequently asked questions

Does Dehumidifier.co.za sell dehumidifiers?
No. We are a free quote service. You send one request and we pass it to independent dehumidifier suppliers and hire firms, HVAC and appliance technicians, mould removal and damp proofing contractors, restoration firms and suppliers of absorbers, humidifiers and purifiers who work in your area. They contact you directly with a price, and you are under no obligation to accept any of them.
What size dehumidifier do I need?
It depends on the size of the space, how damp it is and how warm it is. Units are rated in litres a day at warm, humid test conditions, so a unit removes less in a cool room. The job card on this page works out the floor area and volume of your room and suggests a size from a common rule of thumb. See home dehumidifiers and industrial dehumidifiers.
Will a dehumidifier get rid of mould?
It stops new mould growing by keeping the air drier, but it does not remove mould that is already there. Clean or remove the mould, then find the cause: condensation, a leak or rising damp. See dehumidifiers for mould and mould removal.
My geyser burst in the ceiling. Who can dry the house out?
Call your insurer first, then a restoration firm or a hire firm. Standing water is extracted, wet ceiling boards and carpets that can't be saved come out, and the structure is dried with dehumidifiers and air movers until moisture readings are normal. See water damage restoration and dehumidifier hire.
