UnderDeck The Original® Under Deck Ceiling

UnderDeck The Original is a patented innovative outdoor under deck ceiling system designed to keep the area below dry. It solves the problem of what to do with the damp, dark, unused space below wood plank decks. It’s a great deck drainage system that has a distinct, dimensional design. Unlike the flat, shiny surfaces other systems employ, UnderDeck’s dimensional design hides minor imperfections in joist heights.

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. All water and dirt travels onto the UnderDeck 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. UnderDeck is a unique, functional, and beautiful solution.

UnderDeck adds outdoor living space and value to your home.

You may have a beautiful elevated deck… and it’s probably a great place for cookouts and family get-togethers. But what’s going on in the space below? The UnderDeck Ceiling System can turn the space under your deck into a shaded and favorite outdoor haven – and add value to your home.
An attractive, all-weather UnderDeck outdoor ceiling transforms the underside of new or existing wood decks into clean, dry, bright spaces perfect for:
  • Outdoor retreats, hot tub, sauna
  • Play area for the kids
  • Quiet getaway
  • Cycle, toy, misc. storage, and more!


What’s more, UnderDeck is proudly made in the United States and carries a limited 15-year warranty.
