Precision Underdecking Services Across Centennial, CO

Got an elevated deck with wasted space underneath? Underdecking systems turn that area into something useful by keeping it dry. At Custom Decks, we install quality underdecking throughout Centennial, CO that channels water away so you can actually use the space below your deck. Instead of watching rain drip through the boards onto your patio furniture or grill, a good system catches everything and diverts it away. We work with panel-based systems and gutter-and-channel setups depending on what fits your deck’s design. Whether you want dry storage, an outdoor living area, or just protection for whatever’s underneath, proper underdecking makes it happen.

Our Services

At Custom Decks, we provide comprehensive outdoor solutions tailored to your lifestyle, property, and budget. Our full-service approach covers design, material selection, permit acquisition, and expert installation to transform your outdoor space.

Underdeck Space Options

Turn your protected space into an outdoor living room with furniture and entertainment areas, add weatherproof storage for lawn equipment and seasonal items, create an entertainment hub with TVs and sound systems, install deck coverings like pergolas or solid roofs with shingles for additional protection, or combine options to match your lifestyle and property needs.

Panel-Based Systems

These systems use solid panels installed between joists to create a waterproof ceiling under your deck. The panels slope slightly to direct water toward the perimeter where it drains away. They're clean-looking and work well for decks where you want a finished ceiling appearance underneath.

Gutter-and-Channel Systems

These install vinyl or metal troughs between joists that catch water and channel it to downspouts at the deck's edge. They're typically more affordable than panels and easier to retrofit on existing decks. The channels handle heavy rain well and you can customize where the water drains.

Frequently Asked Questions

Find here the answers to the most frequently asked questions about our expertise.

What's involved in underdeck systems installation?

Underdecking includes measuring joist spacing, installing support tracks or ledgers, fitting panels or channels between joists with proper slope, sealing all connections to prevent leaks, and running drainage to appropriate discharge points.

Can I add underdeck installation to an existing deck?

Yes, most underdecking systems can retrofit onto existing elevated decks. Gutter-and-channel systems are usually easier to add since they install between joists without major structural changes. The process involves accessing the underside, mounting the system components, and ensuring proper drainage away from your home's foundation.

How do I know which underdecking system is right for my property?

Consider your deck height, joist spacing, desired finish appearance, and budget. Panel systems cost more but create a cleaner look and better moisture protection. Gutter systems are more affordable and work well when you mainly want to keep the area below dry. We can evaluate your deck and recommend what'll work best.
