We have an area in our laundry room that sees water leaking into it on heavy rains like today. We thought it may be coming in front the dryer vent but don’t see any difference after filling the outside of the vent with foam. And further looking, it seems to be coming in from lower rather than the vent itself. The outside is a back patio under a raised wooden porch. Could it be from the collected water inside the porous bricks? Don’t see any weep holes back there. Or from the small gap between house and concrete patio? Any suggestions?
