Hi
Looking for advice on how to troubleshoot black mould appearing around UPVC window frame in bedroom. This has appeared over the summer months. Teenager's room so a lot of time spent in there with door/curtains closed.
Leak or condensation issue. Thoughts?
Add a dehumidifier?
Vanity unit (attached photographs) is in high humidity wet room.
Outer coating starting to bubble and flake
Looking for some advice on how to repair / repaint / spray as do not want to replace
Best material that will adhere to the surface so this doesn't happen again?
TIA
