OK, I realized that some idiot used regular old duct tape to install an
entire flexible heat ducting on my house. Needless to say, these
"joints" hace crumbled and fallen apart over time. I'd like to have
this all replaced (removing the duct tape) done right, probably by a
contractor or by myself.

My questions a

1) How can I do it myself?
2) Would a contractor even do a small job like this?
3) What tape can I use to hold these flexible ducts to the ridgid steel
sections?

Thanks!
