Abstract
Abstract A method and apparatus for the repair of leaky gutters by the installation of a semi-conforming, resilient liner. The liner material is selected for its ability to readily form durable watertight joints with adjoining pieces of similar material, or to itself, to provide a watertight conveyance to the downspout for runoff water. The resiliency of the material is selected such that the liner is generally semi-conformal in order to prevent seepage of water between the liner and the gutter, and to allow easy handling and installation. Finally, the liner presented when installed is durable enough and inexpensive enough to make lining of the gutters to repair the leaks more cost effective than replacement of the leaky gutter with new ones. In one embodiment, PVC material and bonding agents, similar to those commonly used in plastic pipe plumbing, are selected for use.
