Mould can form so easily in unventilated bathrooms, especially during cooler months.
Warm steam builds up in your bathroom when you take a shower or bath, and when this steam makes contact with a cooler surface like windows, mirrors, walls and ceilings, little droplets of water form. If not removed, these water droplets can cause dampness which is a perfect habitat for mould to spore or form.
If you do not have an exhaust fan currently installed in your bathroom, we suggest opening a window while taking a shower or bath to allow the warm steam somewhere to escape. However, don't open a door as this only allows the moisture to enter other areas in your home and potentially cause mould issues there. Only open your bathroom door if you are running your exhaust fan.
When your exhaust fan is operating, it is ideal to open both a window and door slightly. This allows the exhaust fan to run more efficiently as it draws cool air from outside the bathroom, and pulls it up through the exhaust fan into the roof cavity where it can find other areas to escape.
