When paying someone to clean your gutters, make it clear with them if they’ll clean the downspouts as well. Some services don’t include cleaning the downspouts — a clean gutter isn’t enough obviously. Better yet, when cleaning the gutters yourself, run some water in it all the way to the downspouts to check for potential clogs. Just in case there are, you can disassemble the downspout or use a plumbing snake to push the debris out. Hose down water once more to ensure it’s all clear.
