Hello.. I privately rent my house.. Soon after having new windows fitted mould started to appear at the top of the bathroom window after heavy rain.. We told our landlord and she said its from the shower.. Im not so sure as everytime it rains the wall starts to drip?? there was no problem before the heavy rain started.. its now been a few months Ive cleaned it numerous times and it comes back worse..
Who do i go to if she refused to find out whats causing it.. ?
