Extractor fan in bathroom window

Anonymous user 28/02/2024 - 2.55 PM

I have a top floor flat (in 3 storey building), and it suffers from bad condensation leading to mould growth in bathroom, bedroom and living room. We do all we can to minimise steam (bathroom and kitchen doors shut, windows open etc) but the problem persists. There is no ventilation built into the flat – which is constructed out of concrete. I wondered then about installing an extractor fan into a window to try and mitigate the problem. I assume the best place for this is the bathroom as the biggest culprit of condensation. 1) Can you install a fan in a window that opens? I don’t think I’d want to lose the ability to open the bathroom window (it’s a single pane double glazed UPVC) 2) Does the job require replacement window or just the glass? Or can it use existing glass, cutting a hole to insert the fan? 3) Is it possible to do this without scaffolding? Many thanks in advance
