Ensuring that properties under their control remain in a good state is a key requirement for landlords and other housing providers under the Housing Health and Safety Rating System (HHRS), and a good maintenance regime is important in reducing the number of calls received from tenants needing to report damp and mould problems in their homes.
During the warmer summer months, reports of damp and mould are less of an issue than during the autumn and winter period, however it is also a good time to act in order to avoid problems with condensation damp and mould later in the year.
The condensation that leads to damp and mould can be a problem in any house, but there are specific challenges with rental properties that can make them more prone to issues.
During normal activities around a house, an average person creates about 2 litres of water vapour each day. In properties that are home to larger numbers of people, such as student housing or Houses of Multiple Occupancy, the amount of water vapour being released into the air can easily exceed 100 litres per week. At a given temperature, the air can sustain a specific amount of water vapour, so in properties where there are more people present, the amount of water vapour being produced can exceed what the air can hold, and this will condense on windows, walls, and other cool surfaces where it can soak in and create damp patches where mould can grow.
Although the majority of moisture in a property is created by the residents, condensation leading to damp and mould can still be an issue in empty properties. Without heating and the natural airflow created through movement, the air can cool, below normal temperatures meaning that even relatively low volumes of moisture in the air can cause condensation.
It does not take long for mould and mildew to develop which can make a rental property much less appealing to tenants and result in costly repairs.
Seeing the signs of condensation early is the key step to preventing moud and damp in future. Ensuring that tenants are aware of the warning signs of condensation and report them quickly will mean that resolving the problem will be easier.
Things to look out for include:
By speaking to tenants about spotting warning signs that could lead to mould in future and ensuring that they keep in regular contact with you, you can act more quickly and avoid expensive redecorating and maintenance bills.
It is the responsibility of the property owner to deal with Condensation and Damp problems, it is important for tenants to do their bit in preventing the problem in the first place.
Key things to consider include:
Many landlords choose to install automated fan systems such as the EnviroVent Cyclone 7, which features sensors that measure humidity levels and adjust the fan power to reduce moisture levels below the point where condensation can be a problem.
Installing whole house ventilation systems such as Positive Input Ventilation (PIV) during routine upgrades to housing stock is the most effective way of avoiding future damp and problems as a result of condensation. PIV Systems run continually and draw fresh air into the home to replace damp or stale air. This keeps the humidity levels constantly low and stop condensation.
Although there is an upfront investment in installing PIV systems, it will pay off in the longer term due to lower maintenance costs and has the benefit of creating a heathier environment for tenants.
