Most HOA boards budget for one fall gutter cleaning and call it done. Ontario’s mix of ornamental and drought-tolerant landscaping creates two distinct debris windows. In late summer, palm trees common throughout the Inland Empire shed dried fronds and seed pods, while eucalyptus trees drop bark and leaves that pack into gutters and resist flushing, requiring physical removal. Fall and winter bring the standard leaf load from Ontario’s mix of sycamore, ash, and other deciduous street trees. Communities with mature landscaping typically need service in both windows. One cleaning a year leaves gutters full heading into Ontario’s rainy season, when sudden winter storms put clogged systems to the test.
