I feel your pain. We endured 9 years of misery at the hands of noisy neighbours in our old house because we couldn't afford to move. It started with just loud talking and laughing through the party wall (into our living room), then the son got an Xbox and was shouting at his online friends until the early hours in his room, which was next to our bedroom. They would also leave their dogs outside barking when they went out, sometimes until late at night.
Then the parents started going on holidays without their kids - cue: loud teenage parties every night. My complaints to them and the parents fell on deaf ears.
When my wife was pregnant, they started this massive construction project to build rear and side extensions - the family moved out and employed dodgy builders who worked 7 days a week. The noise was sometimes unbearable and we never got any warning of when they were going to start drilling/banging, so we were constantly on edge. One weekend, they left an industrial heater on in the house to dry plaster, and it made a loud hum, which reverberated all through our house. They also stacked tiles up on the roof so they blocked the signal to our Sky Dish, so we were without TV for several weeks.
I complained to the council, who at least stopped the builders working in the evenings and at weekends, but we got visits from the neighbours, threatening us because their building project was running behind schedule and they were having to pay extra rent on the house they were staying in. They had planned the whole venture on the basis that the builders would work every day to get the job done quicker to save their pockets. They hadn't given the impact on us a single thought.
When the family moved back in, they were minus the dad. Apparently, the stress WE had caused THEM had split them up.
Things did get a little better - the teenagers grew up and moved out - but we hated our house by that time, and we desperately wanted to move.
We were never more relieved than when we were finally in a position to move, especially as the son had moved back in and the late-night shouting had started again.
