Noticed discolouration around the light switch near to washroom on Saturday morning
@petra and I investigated and reckon there’s water ingress from the outside top of the brick arch
Short term fix: I’ll put a bead of expanding foam along the join. Longer term we might need some sort of drip rail and flashing
Please be very careful around the loosened ply panel. I’ve left it leaning against the wall to dry out a bit. The electrics are safe for now, and it’s unlikely any more water will run down the panel
