Hi all,

We have a flat we let out and the tenants have mentioned that mould is appearing around one of the downlights. We do have an extractor fan in the bathroom that is set up to come on and off with humidity levels and there is a window that they open too when it is warmer outside. I am assuming the mould is attracted to the downlight because the loft insulation can not be laid right up to the light housing so this bit of ceiling will be colder.

Does anyone have any ideas how I can remedy this? Someone did mention to me there is a "dome" that can go over the housing to help keep the area insulated but I've been unable to find anything. It may be that we need to adjust the humidity threshold on the extractor fan but this is fiddly and we find it hard to get it to work reasonably rather than staying on for hours unnecessarily.

Thanks for any help.

Hi neilyoung1,
There are downlighters on the market where insulation can be placed over the top of them. If you do this do not use standard halogen lamps because these will overheat - fit led ones instead.
