Once the gutter will be clean, the next step is to stop it from getting dirty again. And one way to do this is to trim all trees nearby your gutters. It’s a small step, but it can make a world of difference. Usually, the things that occupy our gutters include leaves, twigs, and stones come from trees. Even stones are dropped in from trees by birds. If your trees grow in the winter, it might be wise to find a way to make them grow away from your house.
