Stop in for a cup of coffee

Fine, they get paid their contracted price for work installed properly and they eat the rest while restoring the unsatisfactory work back the way it was. Period.

You are dealing with a incompetent contractor. They only get paid for what they did right per the contract and eat the cost of putting the improper work back to where they started.

Stop being a slave to the contract and negotiate your deal forward out of this mess.

Maybe Im not being clear, but that is exactly what Im trying to explain. If they were too put it back the way it was, I would need the siding (or cost of the siding) refunded to me. They eat everything they have done and must remove the stone back to a clean slate. The problem is they bid the work so incorrectly and cheap $1400, that its going to cost me more $4800 to hire another contractor, hence they cant fulfill the contract and I should be able to deduct that from the remainder that I owe them. Hence trying to negotiate forward from here, sorry if I cant explain it well.
