Expert Under Deck Builders

Under decking refers to the process of enclosing the underside of an elevated deck using a ceiling system to create a dry, functional space underneath. This area is often overlooked but has the potential to be a beautiful and useful part of an outdoor living space.

Under decking systems are designed to provide protection from the elements, such as rain, snow, and sun. These systems can be made from a variety of materials, including vinyl, metal, and wood, and can be customized to meet the specific needs of each homeowner.

At Excel Custom Decks, we understand that the under deck space is often overlooked, but we believe it has the potential to be a beautiful and functional area of your outdoor living space.
