You're welcome. We each need to draw the line where our own ability is not quite enough and the gap cannot be bridged by advice obtained from a newsgroup.
Different people will draw the line in different places. I tend to be cautious, partly because experience shows I can turn simple DIY jobs into difficult ones, and partly because a friend died under several tons of brick rubble because he decided to have a go himself rather than get professionals in to do a job that was just a little too challenging for his own ability.
What concerned me here was that advice was being given without any consideration of the ability of the individual to do the job. The macho aspect doesn't help, with the inference that people are wimps if they won't tackle complex and risky structural work on their own.
Ba11s to that!
My friend's bravado didn't help his wife bring up their three young children on her own after losing the house and getting into huge debt in the process because house insurers don't cover the aftermath of jobs fouled up by inept DIYers. She would have faced bankruptcy if my friend's employer had not helped out. All because of bravado.
If in doubt, let the experts do it. If they get it wrong, as sometimes happens, at least they have insurance, and you can always sue them. And, most important of all, your children will still have a father.
