Custom Underdeck Ceiling Systems

At GV Decks, we install high-quality underdeck ceiling systems that protect the area below your deck from rain, snow, and dripping water. These systems are installed beneath the deck joists to create a finished ceiling while diverting water through a concealed drainage system.

 

From sleek aluminum panels to rich wood-look finishes, we offer a variety of materials and styles to match your home’s aesthetic. Whether you want a cozy lounge area, an outdoor kitchen, or a covered hot tub space, our underdeck ceilings create the perfect sheltered setting.

What is an Underdeck Ceiling?

An underdeck ceiling is a waterproof ceiling system installed underneath an elevated deck. It works by capturing rainwater that falls between the deck boards and channeling it into a drainage system that moves the water away from the home.

 

This keeps the area below completely dry—allowing you to safely add lighting, fans, TVs, and furniture without exposure to the elements. It’s the ideal way to create an outdoor living room, protected patio, or finished storage space under your deck.

Why Install an Underdeck Ceiling?

Creates a Dry Outdoor Living Area

Enjoy the space under your deck regardless of the weather. Perfect for hosting guests, relaxing with family, or building a cozy outdoor retreat.

Protects Your Deck Structure

By diverting water away from your joists and beams, underdeck ceilings help preserve your deck’s integrity and reduce long-term maintenance.

Adds Home Value

A finished underdeck ceiling transforms a previously unused area into valuable living space—enhancing both functionality and resale appeal.

Custom Finishes Available

Choose from a range of colors and textures, including matte aluminum, woodgrain, and beadboard styles to match your design vision.

Compatible with Lighting and Fans

Our systems are designed to accommodate recessed lights, ceiling fans, speakers, and even outdoor heaters—making your space fully livable.

Low Maintenance

Durable materials like aluminum and vinyl resist rust, rot, and mold. Just a quick rinse with water is all it takes to keep your ceiling looking fresh.
