I’ve lived in my terraced house for over 20 years.
My original neighbours (moved out 10 years + ago) planted ivy against the fence on our boundary. The ivy has been there a long time and has pushed two panels over the boundary line and into my garden, the ivy had actually damaged 3 panels but the previous owner changed one as the ivy was sparse along that panel so was easy for them to replace.
The previous owners didn’t realise how much damage the ivy had done until the HA contacted them and asked them to make repairs (it belongs to next door and they own privately). They refused to replace the panels and only offered to support their fence from my side - the reason being that they had decking installed which prevented them from easily accessing the boundary from their side and they didn’t want the hassle of removing the ivy. I refused as it didn’t solve the issue and I have spent a lot of time and money to make my garden lovely so didn’t want ugly supports pushing back a tatty old fence.
New people moved in a couple of years ago. The fence panel closest to the house has pretty much fallen apart and there is now a huge gap which makes sitting in the garden uncomfortable as we can see each other. I tried to cover it some bamboo screening but the ivy roots are big and the fence panel to the left so weak due to the ivy I can’t attach it properly. I covered the gap with a tarpaulin which is both noisy and ugly but at least gives us some privacy.
It’s really getting me down. Obviously I need to discuss this with the neighbours but I’m so wary after the bitterness it caused last time (and the issue wasn’t even resolved), what else can I do?
