Gutter downspout extensions are standard in Seattle Rockeries drainage plans and are included in our emergency drainage solutions. During Seattle rain downspouts divert gutter water away from foundations, landscapes, and gardens. Seattle Rockeries uses flexible, rigid, low profile, and custom downspout extensions to fit your environment. Gutter downspout extensions are used to fix standing water near gutter drains which deteriorate foundations and homes in the Puget Sound. Downspout extensions lead directly into underground pipes to offer seamless drainage from roof to stormwater system.
