Hopefully, you’ve caught a whiff of the mould early, so there is still time to get rid of it (and its nasty smell).
Why your home smells musty
Mould spores are everywhere. But for them to grow, they need moisture. If there’s mould, there’s also moisture. So that pile of damp clothes on the floor starting to smell – that’s mould.
Shani Troubady, Air Quality Applied Scientist at Aeris Environmental, previously told Better Homes and Gardens, “In the right conditions, mould can develop within 24 hours.”
“Most fungi can start growing on surfaces with a wood moisture content of 16% and above, other surfaces such as carpets, plasterboard walls and ceilings, and furniture such as lounge and desk chairs.”
If you have a spill or a leak, it’s vital to clean it up and dry it quickly to prevent mould from growing.
