How your gutter is fastened, is just as important as the type of gutter you select. We use the hidden hanger system. The hidden hanger is a bracket that clips under the top of the front gutter hem and is secured to the back. The bracket is then screwed into the fascia board with a wood screw. Since it’s inside the gutter, it is not visible. This system also allows easy removal of the gutter, should it ever become necessary.
