They probably won't. At best, they won't charge you. But they also won't chip the brush, do anything with the stumps, or regrade what they tear up up with their equipment. Mills don't like yard trees and pine isn't worthwhile for firewood. Processing firewood is also labor intensive so there's not a lot of profit to be had if they have to pay to take down the wood. Even finding people (particularly insured and bonded companies) who will drop the trees for the value of the wood is a difficult prospect depending on what area of the state you live in.
