Hey guys i am wondering if anyone could help me with pricing some underground gutter installation. There is 5 gutters that need to be ran away from the house between 30 and 40 feet. I know they sell the kits so I am wondering how someone would bid something out like that do you do it by the foot? Im not really sure any other way you could get a sufficient price. And price including materials. If anyone could help me out i would greatly appreciate any advice you might have. THANKS!
