For most San Jose homes, we recommend having your gutters professionally cleaned at least twice a year — once in late spring and again in late fall. This schedule catches the two heaviest debris seasons in the South Bay: oak pollen and seed drop in spring, and leaf fall from deciduous trees before winter rains arrive.
If your property has overhanging trees like oak, redwood, pine, or sycamore, three to four cleanings a year is a smarter cadence. Needles and small twigs pack into downspouts far faster than broad leaves and are one of the top causes of overflow damage we see in the area.
Signs you shouldn't wait for the next scheduled cleaning include water spilling over the edges during rain, streaks or stains on your siding, sagging gutter sections, or visible plant growth in the trough. Any of these means debris has already reached a point where it's affecting drainage.
A consistent cleaning schedule protects your fascia, foundation, and landscaping — and it's dramatically cheaper than repairing water damage after the fact.
