Quick answer
How often to clean gutters in the San Ramon Valley: Twice a year for most homes: once in late April or May, after the oak catkins and coast live oak leaf drop finish, and once in late fall, after the valley oaks are bare. The valley has two separate debris seasons because evergreen oaks, redwoods and pines shed in spring and summer while valley oaks, sycamores and sweetgums drop in fall. Homes with redwoods, pines or heavy canopy over the roof usually want a third visit in late summer, when needle drop peaks. Call (925) 905-9555 or get a free quote online.
