To ensure that your Audubon LeafGuard Gutter System job is done expertly and on time, Audubon has an in-house job expeditor, whose job is to inspect your home for unique or unforeseen situations that cause a problem during installation. By evaluating (or double-checking) the job before hand, installation problems can be avoided. Other companies don't use the expeditor system. They rely upon their salesman, which skips the double-checking process and can create difficult situations between the removal of the old gutters and installation of new ones.
