How Condensation Control Can Stop Black Mould

Few things can be more concerning for tenants than black mould. Not only is it unpleasant and unsightly, but it can pose a health hazard to many people, not least anyone with a respiratory condition such as asthma.

While the harm it does is not usually fatal, in some cases this can happen, a noted example being the death of two-year-old Awaab Ishak in a mould-infested home in Rochdale in 2020. This led to new legislation in this area on social housing, although further legal regulation through the Renter’s Reform Bill has stalled as the legislation was halted by the election.

Black mould does not appear by magic. It is caused by damp inside the home, which arises from a range of causes. In some instances, it might be a leaky roof, problems with pipes or ventilation issues. But if the end result is condensation, it creates damp and humid conditions in which the spores can thrive.

However, there are forms of condensation control that can be introduced to the home to help tackle the issue.

There are two basic ways of preventing condensation. One is to stop the damp at source through effective damp-proofing to keep moisture out, as well as fixing any issues with the pipes or external structure of the house.

A second method is to dissipate the moisture that is there. That can be done through the fitting of window vents, keeping windows open, or using a plug-in dehumidifier.

The problem with the second of these is that it means tenants either have to put up with rooms where windows are left open being colder, which is bad news when using the bathroom on a winter morning, or face a higher energy bill for running a dehumidifier.

Damp-proofing, however, is a more permanent solution, a one-off cost that ensures the source of damp is cut off, stopping condensation and giving black mould no chance to flourish.
