Seamless gutters need cleaning 2-3 times per year in Connecticut – typically late spring, fall, and sometimes mid-winter if ice buildup occurs. The seamless design means less debris gets caught compared to sectional gutters, but you still need to remove leaves, twigs, and other material. Check mounting brackets annually for looseness, especially after heavy snow loads. Inspect for any dents or damage from falling branches or ice. Most maintenance involves basic cleaning and visual inspection. Gutter guards can reduce cleaning frequency but don’t eliminate it entirely. Professional maintenance checks every few years help catch small issues before they become expensive problems.
