The good news for you is you'll be at home with your family, as apposed to being away.
Many of my climbing friends are rope access guys working on rigs and this does their head in, especially with a young family.
As for having a good work/home life balance then you must understand there are many factors that can and will put a spanner in the works. Jobs are delayed by customers, the job takes longer, things can't be finished etc, tiles don't turn up, new deadlines are set, all these and many other factors can mean your pleasant weekend could go out the window.
My mate started tiling and vowed hi wouldn't work weekends, and to be fair he didn't for a while, then it was Saturday mornings, then all Saturday, then Sundays. Now he's given into it.
