Winter condensation challenge
How to combat mould and condensation in tenanted properties
Winter is a challenging part of the year – people spend more time indoors and lower temperatures do not encourage keeping windows open or at least ventilating properties frequently. 2020/21 winter may be even more difficult due to COVID-19: everybody is encouraged to spend more time at home and it will translate into higher condensation levels. Human bodies produce moisture (breathing, exercising indoors, cooking, showering, washing up etc.) which will need to be extracted from the property, otherwise, it will start condensing on the coldest surfaces (windows, corners, external walls). The next stage is mould growth – damp walls are an excellent environment for mould to grow.
Signs of condensation:
- Water condensing on the inside of windows or window sills
- Water collecting on tiles
- Black mould dots spreading from corners and then all-over external walls and skirting boards.
- Black mould growth on silicone seals
How is moisture extracted from flats?
- Air bricks/wall vents
- Opening windows
- Keeping window air trickle vents open
- Extractor fans in kitchens and bathrooms
- Mechanical ventilation systems
