Hi Everyone, I have a property owned for almost 3 decades. Recently I have had mould appearing on the inside wall below the front ground floor window.
Despite painting over with anti-mould paint the mould keeps reappearing. I have a suspicion that it is connected to the insulation which was done approx 10 years ago. I never had this issue before the insulation was done.
The insulation was done with the labour version of the green new deal ie was grant-funded. I still have the 25-year guarantee for what it’s worth. My understanding is the roof was done but I’m pretty sure the walls too.
Since the works were done it has been rated C (EPC). The current tenants ensure the house is ventilated when drying/washing clothes etc.(which can sometimes cause issues).
The house is a terrace built around 1890ish. Please find attached a picture of the mould (main pic). Hope that helps. I’m at a loss but if you/the readers ask me anything – I would try my best to answer.
My late mum did say mould periodically returned, but it despite the passing of 3 decades it seems to have only become an issue shortly after the insulation.
Any thoughts/ideas/recommendations as to what to do?
