The EZ Dock System has a full 8 year warranty from the factory. If your dock system fails due to a defect in the dock it is replaced with a new dock, not a pro-rated amount based on the 8 year cycle.
EZ Dock is a life time dock and designed to provide a lifetime of service with no maintenance. Today we have customers still using the same docks purchased when EZ Dock was introduced over 17 years ago and they look as good today as they did when initially installed.
