Not sure if this is the right place but what the heck.
We may need to get a stair lift fitted for DW. But the only place it could go is on the party wall of the people we're semi-detached with (if you see what I mean).
If we had one fitted, would next door be able to hear it in operation? Would it be so loud as to be a nuisance?
Anyone any experience of this. We get on OK with NDNs and I've no wish to antagonise them.
