Haven’t managed to read all the replies as am at work but to answer a few points raised.
Yes the walls are super thin - we can hear their kettle bubbling when it boils that’s how crap they are. When they first moved in they washed everything - a minimum of 3 loads a day for 7 days and we let it go as moving in noise, they’ve now not done any washing at all this last week so it was a surprise that they chose to put a wash on (what I would call) late last night.
They don’t work late, he’s home at 4 every day and works mom-fri and she’s a sahm so it’s not that they don’t have other times to do it either.
I totally appreciate washing machines are a normal part of everyday living but to me consideration of neighbours when in a terraced house should be up there - the way our houses are laid out putting our machine on would have no effect on them but on our other neighbour - we don’t put any washing on after 7pm as our spin is also horrendous and we don’t want to piss her off.
The other neighbours were really very loud and they have affected our sensitivity for sure, they would stomp, bang, crash, scream, shout, knock on the walls, chase each other around, pulled up every carpet in the entire house etc at ungodly hours all the time, the parents then moved abroad leaving their 17 year old to live alone in the house for 2 years which I’m sure you can imagine was incredibly stressful and even louder with the friends and parties. We only hung on as we knew eventually the kid was going to uni and the noise would decrease.
I can see what you are all saying about leaving it as we haven’t had much contact with them and it wouldn’t make a great first impression. But just to defend myself a bit (as people seem particularly mean on mn lately) I wasn’t going to go round all guns blazing, I was actually going to ask if they could check the machine isn’t touching any walls thus increasing the vibrations to our side, my son is little and had school so I don’t think it’s much to ask for an undisturbed sleep for children (I appreciate to some adults 10:30 isn’t late).
We are looking at moving but these things take time.
Thanks for all the comments (really surprised by how many there are) at least you can always rely on mn to give it to you straight
, I will keep reading but I’m in meetings most of the day so might not get round to replying much.
