The neighbours next door are a massive family and are only renting. They've lived there 4 years. We live in a terraced road and I live with my mum only. (Mum owns our house, but next door rent it out) - hence this big family there now. We dread the summer as they're so loud; in fact, they're the loudest in the entire road!
We recently spent a small fortune on a fence (it is our responsibility as per the deeds). It was expensive and something mum and I saved for. However, next door's tenants have a trampoline right up against one of our fence panels that moves back and forth when their kids are jumping on it. They're not the most approachable of people, but somehow we managed to see them and told them politely that we don't want to spoil their kids fun, but could they move their trampoline just a little away from our fence as they're pricey to replace and it was continually moving. This was agreed and they moved it about half a metre! However, they went on holiday for a few weeks, came back and the trampoline has worked it's way back up against one of our fence panels again, and again, the panel is moving to the jumps of when the trampoline is in use by their kids again.
Any ideas what we should do? It's only me and mum against them all. Thank you.
