UnderDeck The Original. An attractive deck drainage system for elevated decks.

UnderDeck The Original® is a patented innovative outdoor ceiling system designed to solve the problem of what to do with the wet, dark, ugly space below second-level decks caused by rain. It’s a great deck drainage system that has a distinct dimensional design which hides minor imperfections in joist heights, and is much more attractive than those flat, shiny surfaces other systems employ. UnderDeck solved the problem by creating a unique, functional, and beautiful solution. What makes UnderDeck The Original ceiling system so innovative is its simple and efficient use of vinyl gutters and panels which attach to the joists below the deck. It captures and diverts the water and dirt that falls through the gaps in your deck and the water and dirt travels onto the UnderDeck’s System and exits at the end of the deck, or is channeled through rain gutters and downspouts to direct the flow of water away from your home.

So no matter if you simply want to enjoy a restful snooze lounging outdoors, send the kids to play outside, host a friendly neighborhood Bar-B-Que, or perhaps enjoy your outdoor hot tub, there will be no concern that a little rain might disrupt the activity.

UnderDeck The Original has an added benefit – the UnderDeck Gutters and Collector Panels can be easily removed and reinstalled to provide for access above the system. If you want to add accessories like ceiling lights or fans, you can it at any time!

Rain gutters and downspouts are not necessary, however, most applications do utilize them to provide a controlled manner to disperse water.
