.... So we're doing some work for our utility room. DH and DS have been drilling out floors and walls to lay new gas and water pipes
This work was done between the hours is 11am-2pm, off an on. And they've done this once each weekend for thelat three weeks.
So 2-3 hours of noise either on sat or sun, once a week.
It is noisy masonry work and it is on a shared wall.
I just had the neighbours round at 2pm today complaining about the noise... The wall/corridor backs on to their living room. They said that it was an unreasonable amount of noise that had been "going on for months"
I refuted that it had been going on that long, bit acknowledged it was noisy and apologised, but it was not at an unsociable hour. They claimed it was, because they couldn't watch the TV.
So I asked when we should be allowed to make the noise and would they rather it be done at 8/9 at night during the week?
Then she muttered in about how DH could do it during the day in the week. I said, well, he can't because he's at work until around 6:30pm, and (again) it would not be fair for him to start the noisy work at around 8pm on a weekday evening.
Then she went off on some crazy rant about how DH doesn't even go to work,and his van "never moves"... and that workmen never make noise at the weekend, so DH should be doing the drilling during the week 
Bear in mind, her DH works during the week, leaving at 7am (hence partly why we don't drill in the evenings). He and DH often bump into each other in the morning and say hello, and they go to bed around 9pm.
Anyway, are we being unreasonable for drilling masonry (floors/ceilings) between 11-2 one day of the weekend over the past 3 weekends?
