Many homes see the worst mould problems in winter because cold surfaces and indoor moisture work together more aggressively. If mould appeared last winter and you want to reduce the chance of it returning, the most useful response is to treat the affected areas properly now and improve the room conditions before the next cold period arrives.
Why winter makes mould worse
- external walls run colder
- windows collect more condensation
- rooms are ventilated less
- laundry and indoor moisture have a bigger impact
- corners and hidden spaces stay cooler for longer
A better off-season plan
Use warmer months to reset the affected areas. Remove visible mould with Mould Removal Sprays, prepare damaged areas where needed with Mould Prevention & Primers, and only use Anti-Mould Paint when the surface is fully ready for its finishing stage.
Reduce the conditions that fed last winter’s patches
- improve extraction and background airflow
- review furniture placement on cold external walls
- monitor recurring condensation hotspots
- check whether staining or damp points to a wider issue
