Is my excessive condensation and rapid onset mould a problem from the communal piping or is it my problem

Anonymous user 23/02/2024 - 2.41 PM

Over the last 14 days my small toilet (with functional extractor fan that is permanently on) has started to gather excessive damp on the wall behind the toilet from ceiling to floor. Over the weekend i noticed mould in the corners and down the wall. There does not appear to be any leak in my toilet and i cannot see anything else visibly causing a leak. the only visible pipe is the waste pipe at the back of the toilet and i cant see any possibly of this causing the damp. As a lease holder i am responsible for maintenance of any pipes inside my property but communal piping is the responsibility of the council. I have called the council and they are reluctant to help and threaten that if they send out a surveyor and it is not communal maintenance then i face high fees. They also say that the surveyor could take weeks to come regardless. I feel sure this must be a problem related to communal piping but how can I be sure? Does anyone have any advise. I can post pictures of the damage. Do i stand to pay unnecessary high costs for a private surveyor who then cannot attend the problem as its communal? Any support, guidance or experience from anyone out there would be great!!

Are you a tradesperson and able to answer this question?

Hi, this is a hard one, first thing is extractor should not be on all the time, should be on switch timer, i think all pipes would be better if lagged and box in, also good ventilation, if still got prob you will need to get it look at fined out what the problem is best wishes colin.

Hi, This is a comen problem!! The weather has changed and the temp drop will mean a cold bridging problem will occuer "cold outer walls meet warm air in the loo hay presto condensation and mould. The fan should not be running all the time so you have a fault or it has been installed incorectly. The wall will need to be lined with a closed cell insulation foam,then re boarded with 12.5 foil backed plasterboard, the best way is to foam fix the insulation and plasterboard so as not to break the new thermal efficancy that you have created, Dry line the walls not pink plaster as pink plaster holds the cold and dry lining with is special make up keeps a warmer surface,paint only with a bathroom paint, keep the room at a steady temp. Lastly the rear of the cystern should have a 3mm sheet of neoprean glued to it this will stop the condensation to the rear of the loo. Fix the fan or install a heat exchanger fan this will re cycle up to 84% of the heat during the extraction process. regards Ashley
