Types of Under Deck Drainage Systems

Under deck systems can vary in styles and designs to suit whatever outdoor aesthetic your space requires as well as the stage of construction your backyard area is in.

Trough systems, such as the Trex RainEscape line, are installed in the initial stages of deck building as they are attached to the deck joists.

Channel drainage systems, also referred to as panel drainage systems, such as UpSide Deck Ceiling and Zip-Up Under Deck Drainage can generally be added at any stage of deck construction and connect to the bottom of joists and ledgers holding water-diverting panels in place at an angle.

Steps to Clean Deck Drainage Systems

Wipe Away Debris

Use a household broom, not a shop sweeper, to lightly brush away any dust, cobwebs, or pollen that may have become stuck to the underside of your under decking drainage line.

Next, use a clean towel or dishrag dipped into some warm soapy water to clear away any stuck-on debris or liquids that may have dried on the surface. Standard household cleaners such as TSP, Simple Clean, or OxyClean will do a marvelous job at polishing away any spots; otherwise, common dishwasher detergents such as Dawn® or Joy® can be used as well.

Check for Clogs

Standing on top of your home's deck, pour a few cups of clean water on the deck boards, allowing it to fall through the deck board gapping and into the deck drainage system.

After pouring the water, watch the gutters installed on your under decking method and confirm that roughly all of the water poured empties out. If there seems to be a significant amount not leaving through the gutter system, inspect your drains for any clogs that may have built up from dropped items or fallen leaves.

If a clog exists, pinpoint the panel and trough section, remove the blockage, and reset the deck drainage system.

Remove Panels and Wipe Down

If working with a paneled under deck system like Zip-Up Deck Drainage, simply remove the panel where the clog or issue can be found to fix the issue. Panels can be removed by pushing up in the center of the panel, then use a pry bar or claw-end of a hammer to further unsnap the seal of the panel along the sides.

Replace Broken Panels, Channels, or Troughs

If an unforeseen incident caused a rip, tear, or break in your home's under decking setup, be sure to replace any broken components as soon as possible to prevent moisture from being caught in the area. It's best to install deck drainage systems in temperatures above 40° F or higher to prevent the cold from affecting the pieces.
