We have a house with a grassy backyard that grows right up to the edge of the house. We keep grass well maintained- short. Sprinkler water & rain water run towards the house and get the walls very wet and is leaving a green water stain on the wall (stucco). Is this something to be concerned about? Will it cause termite problems? mold? What can be done? Get rid of the grass? Put down concrete? Re- level the entire yard to slope away from the house? Who do I contact to evaluate the situation? Landscaper or gardener?
