I noticed a weird texture around my bathroom fan, it is not mould but definitely discolored and the drywall is deteriorating around my ventilation fan. I emailed my Heating and cooling guy:

Hello, It appears that moisture from the bathroom fan may be freezing and then dripping back down. We recommend contacting the company that handles attic-related concerns. This is usually something to do with the ventilation or the insulation.

Does anyone have any recommendations or contacts for attic related concerns/insulation? It is a 2021 home and do not want the problem to get worse. I am always using the fan during showers and opening windows when i can.

Thanks!
