Could anyone help me with a bathroom downlight problem? I've just bought my first house and the bathroom (which gets a lot of condensation) has downlights over the bath. These downlights aren't flush with the ceiling, to the extent I think condensation is rising up throught the bathroom and into the loft space.
Is there a sealant that I can use to fill these holes?
Grateful for any advice, I know nothing about DIY so please assume complete ignorance on my part!
