Why Install an Under-Deck Drainage System?

  1. Increased Usable Outdoor Space: An under-deck drainage system creates a dry area beneath the deck. This space can be used for storage, a patio, an outdoor living area, or even an outdoor kitchen. It effectively doubles the usable outdoor space without the need for additional construction.
  2. Protection from the Elements: By diverting water away from the area underneath the deck, these systems protect the space from rain and snow. This makes the under-deck area usable even during inclement weather.
  3. Improved Aesthetics: Under-deck drainage systems can be designed to blend seamlessly with the existing deck and the overall aesthetics of the house. They can also conceal unsightly overhead joists, creating a more polished look for the under-deck area.
  4. Increased Property Value: By providing an additional functional outdoor living space and improving the overall appearance of the deck area, these systems can enhance the property’s value.
  5. Reduced Water Damage Risk: By channeling water away from the foundation of the house, under-deck drainage systems help reduce the risk of water damage to the home’s foundation and lower levels.
  6. Ease of Installation: Many under-deck drainage systems are designed for easy installation, which can be a cost-effective solution compared to other types of home improvement projects.
  7. Customization Options: These systems often come with a variety of materials and finishes, allowing homeowners to customize the look to match their home and landscape.

In summary, under-deck drainage systems not only maximize the usability of outdoor space but also protect the deck structure, enhance the home’s appearance, and can contribute to the overall value of the property.

Underdeck drainage systems come in two primary varieties. We highly recommend the EPDM DekDrain system, which is installed above the joists prior to laying down the decking. Alternatively, there’s the ZipUp Ceiling system, which is fitted after the decking is in place. The DekDrain offers superior protection for the deck’s structural framing. On the other hand, the ZipUp Ceiling system has a tendency to retain moisture, potentially leading to rot. To mitigate this, it’s crucial to periodically remove the panels, ideally every few years, for a thorough inspection of the framing. It’s important to note that no available systems on the market are completely watertight; they serve primarily as water diversion mechanisms rather than absolute waterproofing solutions.


The DekDrain system offers several benefits for homeowners looking to protect and enhance their deck and outdoor living space. Here are some of the key advantages:

  1. Protection of Deck Structure: By being installed over the top of deck joists before the decking boards are laid, the DekDrain system helps protect the wooden structure from moisture, thereby preventing rot, mold, and mildew. This extends the life of your deck significantly.
  2. Creates Dry Under-Deck Space: The system effectively creates a dry area beneath the deck. This space can be utilized for additional outdoor living areas, storage, or recreational spaces, maximizing the utility of your outdoor area.
  3. High-Quality Material: Made from EPDM, a durable synthetic rubber, the DekDrain system is designed to withstand harsh weather conditions, UV rays, and wear and tear over time, ensuring long-lasting protection.
  4. Low Maintenance: Unlike other under-deck systems, DekDrain requires minimal maintenance, saving time and money in the long run.
  5. Improves Aesthetics: The system can help improve the overall look of the under-deck area, making it more appealing and usable. This can be particularly beneficial if the under-deck area is visible from other parts of your property.
  6. Enhances Property Value: By protecting the deck and adding usable outdoor space, the DekDrain system can increase the value of your home.
  7. Environmentally Friendly: EPDM is an eco-friendly material, making the DekDrain system a good choice for environmentally conscious homeowners.

Overall, the DekDrain system is a practical investment for those looking to protect their deck from moisture damage while also expanding the functional living space of their home.

Instead of debating over having a deck vs patio, consider having both. With a two-story deck, meaning you have an elevated deck to create a room beneath, you can install a ceiling to create a more finished living space with lights and fans. With a protected area, you can be as creative as you like! Here are a few ideas:

  • Add a big screen TV, sound system, comfortable seating, and a wet bar, and you instantly expand your party space by finishing the area beneath your two-story deck. Be sure to buy a weatherproof TV for outdoor use.
  • Install a full outdoor kitchen or roll out a portable cart to your patio table and chairs for your next dinner party. Eat outside without having to worry about the forecast with your under-deck living space. Add some screening, and you won’t even have to worry about the bugs.
  • Create a comfortable seating area. Think about how you’d like to use your deck for yourself, your family, and for entertaining with friends. Instead of uncomfortable lawn chairs, maybe you need a couch and chairs with fun and functional cushions. Perhaps you’d like to add a hammock or a swing. Really great seating will make you want to spend more time on the deck!
  • Relax and enjoy. Nothing beats a hot tub in the quiet, private space beneath your two-story deck. Make it your weekend oasis.
  • Increase your storage. Everyone these days could use a little more storage. Check out some of these creative storage ideas for under your deck.

  • Limited Lifetime Warranty
  • Easy Access to Electric, Plumbing or for deck inspections.
