I have gas lines that stick out about 1 inch below the joists in my basement. This actually starts right where the pipes enter my basement - they go over and then down. I need that "down" part to be a few inches shorter.
So my choice is to fur out a 3 foot section in the ceiling (which will look fine because it is against the back wall) or to get the pipe moved up. The section that needs rerouting is 20 feet.
So my question is really about who I would hire to do this, and what would be involved in doing it?
