Relatively new neighbours (a couple in their late 30's) wake up every day at 5.50am and start slamming doors, it goes on for around 2 hours, they slam doors and what sounds like stair-gates around 30 - 40 times. It wakes up my children every morning without fail. The same thing happens at around 5pm to 8pm and it can be even noisier -they also DIY late into the evenings and leave their dogs barking for 2-3 hour stretches during the day (they have 4). That doesn't bother me as much as the door slamming as it wakes the kids up. I've had two different neighbours previously and have not had any sound issues at all. I can't talk to them unfortunately as the are CFs. Realistically, what can be done? we both own our property.
