Is it ok to ask my neighbors to take down their windchimes?
Why do want them to take their wind chimes down?
They make so much noise that I can't concentrate.
It's generally not right to tell people what they can do with their home, and wind chimes typically aren't very loud. If they really are bothering you so much you should change rooms so you can concentrate better.
It's my home and I have the right to have peace and quiet if I want.
If they were doing something noisy I would agree that they are being rude, but wind chimes aren't loud. However, if the noise really is upsetting you you could try to work out an arrangement with your neighbor where they only put the wind chimes out on certain days or at certain times. It's usually not a good idea to try to tell people what they can and can't do though.
