How to Install an Underdeck
Want to learn how to install an underdeck ceiling? Then join Done-In-A-Weekend Extreme Projects host Doug Scott to see how you can turn unused space into additional outdoor living space. Not to mention, space that creates shade, privacy and water diversion!
In this episode, Doug joins Heath Bowman, founder and CEO of Southeastern Underdeck, and his install crew at a North Atlanta residence to see exactly how it’s done.
Heath begins by outlining for Doug the basic steps to install an underdeck ceiling (this one was 400 sq feet):
1. Spin a level laser to determine the underdeck pitch.
This move ensures that all captured water runs to the downspots and away from the home. Next, the underdeck begins at three inches below the band of the home. The band is the boards that cover the seam where the house foundation and sill plate meet. From where it starts, the underdeck is then pitched 1/8 of an inch per foot away from the home.
2. Install wooden end caps, wall channels and gutters.
Although other end cap materials can be used, Heath recommends using treated lumber. Doing so, he says, will likely match the look of your existing decking, and will help protect against both wildlife (birds and squirrels, for instance) and the elements.
3. Install underdeck panels and optional accessories.
As the panels are being installed, Heath’s crew installs optional accessories—lights, fans and Bluetooth speakers. In addition, Heath tells Doug about the great number of panel and trim colors, and textures that are available for homeowners. This allows folks to mix and match panel/trim combinations.
Finally, Doug ends by asking Heath about the maintenance involved in an underdeck system. Just like gutters, Heath notes that he instructs his clients to plan on maintaining their underdeck every three to five years.
And, it’s that easy. In just two short days, Heath and his team have transformed this home’s underdeck space into additional dry, protected usable outdoor living space. Not to mention, it looks absolutely amazing, too!
