I recently had my landlord come to my rented property as I noticed black mold forming along all our single glazing windows. It was much worse in the two bedrooms of the property. All the windows generally have condensation on them quite often and the two bedrooms are a lot worse. There is often pools of water on the window sills.
My landlord has said that this is because of my flatmate and I drying washing in the house and has basically said it is all our fault as we are not ventilating the property properly. She further said in an email that the bathroom was the worst affected area, which it isn't.
My flatmate and I regularly open all windows in the flat, but this rarely clears the condensation on them and it just causes the flat to be absolutely freezing, bearing in mind over the past few months the temperature outside has been around freezing. In addition to this the clothes drier is kept in the livingroom and the livingroom door is always shut to keep heat in. The bedroom doors are regularly shut too.
We are not sure if it is the case (as the landlord said) that the clothes drying is causing the mold and damp in the bedrooms as this seems unlikely, however, she will not listen. In addition to this, it appears to us that the single glazing windows, especially in the bedrooms, are letting in water.
We have one again cleaned the mold away, this time using neat bleach as instructed by the landlord.
We are hoping to just get a little bit of clarification here about whether the landlord is right or not in relation to the washing in the livingroom causing the condensation in the bedrooms. And also about the likelihood that the windows in the bedrooms are just not as tightly sealed as the other areas.
