A chat or a note to start with is the best course of action. They may not realise that can be heard.
We had a real problem with the family next door and it was a nightmare for FOUR years. Firstly, there was the DIY at 2am in the morning. Then there was domestic violence which was two-way (ie her beating him up and him beating her up). Then came battles in the street between his family and her family. This included brick throwing, running each other over with cars and throwing petrol bombs.
The children, although tiny, were unruly. They threw stones, spat at people, unrinated and pooed in the street and in gardens and hurled abuse at visitors to our house.
I live in a cul-de-sac so everyone was affected. Gentle complaints did no good. Finally, there was an arson attack on their home (by a family member) that resulted in our property being smoke-logged and the street being roped off and swarming with police. Action swiftly followed. A catalogue of incidents was compiled, court orders were issued ordering family memebers not to enter the street and ASBOs were issued to the husband and wife.
Everything calmed down and we had a year of peace. They recently moved out but still own the home, which they rent out to a nice quiet couple.
Smurfy - keep a record of the incidents - time, date, type of incident etc. You may find it comes in handy. Good luck
