We installed a pond appox. two months ago and it seems like every three or four days the guy is calling complaning that the pond is leeking. It is just the ground settling and we keep fixing it for free what can i do. When should I start charging. We are driving about 20min. one way every time. We cut costs on the pond so it probably only cost about $500 for him. I feel sorry for the guy having to get up off of his butt and go out and move the mulch back and pack a little dirt in the low spot once in a while and it has slowed down he hasn't called in about a week this time. Getting Kind off angry with him he still owes me $400.00 from another job we did later.
