Abstract: A vibration and sound deadening treatment applied to the exterior of downspouts or other gutter pieces which quiets any sound generated when water or other weather contacts the downspout. When placed on the exterior of the downspout, especially near turns in the spout, sound generated by rain and water moving through the downspout is dampened by reducing or removing completely the vibrations generated by the rain and water. This prevents the need to place anything inside of the downspout that may wind up clogging the spout and drain.
