Thanks for the reply, Im confused though. You're saying I should make them flag the heads but its still my fault if I hit one? Or did you mean make them flag and then its THEIR fault if they miss one?
I estimate 30% of the lawns are irrigated. My partner and I expect to do 10 lawns per day for 2 work weeks. So I would spend 3 weekend days flagging 10 irrigated lawns a piece and perform service on those lawns on 3 separate days.
Is it industry standard to have the customer flag the heads? My aeration experience is on sports fields where I as the contractor was responsible.
