I live in a quite close and my house is right at the end, so I took a couple of days off work during the week back in the summer to do mine so all the grinding noise etc was done with minimum disturbance to my neighbours as most of them were at work.
I don't think I would have been very popular doing it at the weekend and watch out for any sparks from either the welding or grinding coming in contact with any glass as it will burn into it.
