The repair involves removing water from the pipe and re-flowing the solder into the joint. 30 minutes and maybe $60 labor (min charge for 1 hr). Removing the joint and adding two joints adds another weak point that could leak. Although there are splices that can be installed for this type of repair, it's easier and cheaper to re-flow the solder if the pipe is otherwise sound (not corroded with mineral deposits). Mineral build-up would require to removal of the bad joint. Double the price to $120 for that.
Reynolds Wrap, just stretch it smooth
