Under Deck FAQs

WHAT IS AN UNDER DECK SYSTEM?

The underdeck itself is exactly what it sounds like, the space underneath a deck. For most people, this is usually the place where lawn equipment, gardening supplies and other clutter is stored.

In short an underdeck system is a deck ceiling and deck drainage system that turns that old storage space into a functional outdoor room that can add value to your home.

WHAT TYPES OF UNDER DECKS ARE THERE?
  • Vinyl – A DIY product. Isn’t as effective for drying under the deck.
  • Aluminum – Aluminum is not approved metal for attaching underneath the deck due to the ‘galvanic reaction’ that occurs with the copper preservatives that are in pressure treated wood used for decks. The copper will destroy the aluminum, which is not recommended. 
WHAT DOES AN UNDER DECK COST?
The cost is surprisingly reasonable. The underdeck system can be installed to any new or existing deck. The underdeck system is installed underneath an existing deck, which is how the cost is so affordable for the homeowner. When an underdeck system is added, the homeowner is gaining outdoor space that will add value to your home.
HOW LONG CAN AN UNDER DECK LAST?
An underdeck will last a homeowner a lifetime. Undercover Systems provides a warranty that is good as long as you live in your home. Our competitors can’t offer this warranty.
