The average NZ family produces around 8 litres of moisture in the home each day. Add some wet Wellington weather and rental properties can struggle to deal with the excess water.

Mould and mildew accumulate in damp and poorly ventilated buildings. Exposure to the likes of mould and dampness can cause or exacerbate existing health problems as well as deterioration of the property. That’s why it’s so important that both tenants and landlords understand their responsibilities and do their best to minimise damp related issues.

Landlords have an obligation to ensure their rental properties can be well heated, ventilated and maintained. If there’s a useable fireplace, the chimney needs to be safe to use and regularly cleaned while ducted heating and ventilation systems also need regularly servicing.

Tenants are responsible for keeping the rental property in a reasonably clean and tidy condition that doesn’t encourage mould and damp. Some strategies for keeping a home dry and healthy include airing mattresses regularly, not using gas heaters, getting underfloor insulation installed, not drying clothes inside, keeping curtains open to let sun in, and generally keeping the house well ventilated.

It is recommended that the tenants and landlord inspect the property together and while noting any existing damage in a property inspection, also look for any signs of mould or damp. A plumbing company may also be able to do a check to ensure there are no unwanted leaks. This is the best time to agree when and how these will be addressed. It may also be worth approaching a house builder in your local area.

A rental property that’s warm, dry and well-insulated will not only help tenants avoid health problems but they’re also more likely to stay longer. These properties are more sought after and can attract a higher rent.
