During the winter, doors and windows are typically kept closed in HMO rental properties to keep out the cold. Without a continuous flow of fresh air, the relative humidity inside the house rises, and the internal atmosphere quickly becomes full of moisture. Eventually, the moisture will cause condensation, particularly with the temperature fluctuations that occur during winter. If this cycle is repeated, any water droplets forming on cold surfaces can lead to mould, which is a headache for HMO landlords.
Mould is a fungus that grows easily in homes by feeding on moisture, warm air and dust. The key to preventing mould is simple - moisture control. Here are our HMO management tips for reducing moisture:
Drying clothes
Drying clothes on a radiator creates condensation and prevents the central heating from working correctly. When it's too cold or wet to dry clothes outside, use a clothes airer in a well-ventilated room. Make sure that washing machines and tumble dryers are properly vented.
Open a window and close a door
A shower or a boiling kettle increases the humidity in a room. Closing a door can prevent moisture from spreading throughout the house. Where possible, opening a window will allow excess moisture to escape outside. An open window can prevent help condensation from forming inside windows and walls.
Check windows and window sills
Condensation on the inside of windows, or black spores on the window sill are signs that mould has begun to grow. Wipe away condensation and make sure trickle vents are opened. Use a mould removal product to clean away any mould.
Don't overfill cupboards and wardrobes
Air can't circulate in a cupboard or wardrobe crammed full of kitchen goods or clothes, which helps mould grow.
