DECK DRAINAGE FAQs
What is a deck drainage system and why do I need one?
A deck drainage system channels water away from your deck, protecting the frame and area underneath from moisture damage. It helps prevent wood rot, mold, and mildew, while creating usable dry space below.
What’s the difference between over-joist and under-joist systems?
Over-joist systems are installed before the decking goes down and provide the highest level of water protection. Under-joist systems can be installed after your deck is built and are a cost-effective way to retrofit an existing structure.
Can I install a drainage system on an existing deck?
Yes. Under-joist drainage systems are specifically designed for retrofit applications and are perfect for adding water management to an existing deck.
Will a drainage system affect the look of my deck?
Properly installed, drainage systems are discreet and often hidden from view. Over-joist systems are covered by deck boards, and under-joist systems are installed beneath the deck and can even improve the look of the space below.
Do drainage systems require maintenance?
Minimal maintenance is required. Keeping the system clear of leaves and debris will ensure it continues to function properly over time.
Can I use the space under my deck after installing a drainage system?
Yes. With a proper deck drainage system in place, you can turn the space beneath your deck into a dry area for storage, entertaining, or additional outdoor living.
