I am having a problem with bathroom moisture. Everytime the shower is used, it takes forever to evaporate, condenses on the ceiling only and causes problems with the paint and drywall. This seems to only happen during the winter (live in MB, Canada). The fan seems to be working fine as I see steam venting from the outside.
What is going on and how can it be solved?
Could you please email me your suggestions. Thank you for your muchly appreciated input.
