As your local underdeck contractor, Bevilacqua Deck Builders turns the space beneath your deck into a dry, finished area you can actually use. We design and install underdeck drainage and ceiling systems; complete with lighting, fans, and finishes. This way, you get protection from the elements and new square footage for living, storage, or entertaining.
Turn the unused space beneath your deck into a clean, dry, and comfortable outdoor living area with premium underdeck systems designed for performance and longevity.
Wide Variety
An underdeck system transforms the often-unused, wet space beneath an elevated deck into a dry, functional, and aesthetically finished area.
Direct rain and snow away from your deck surface to transform the space below into a dry, comfortable lounge, patio, storage zone, or hobby area usable in more seasons and for more activities.
Integrated gutters, panels, and downspouts manage water efficiently, helping protect your deck framing, outdoor furniture, and stored items from moisture damage and long-term wear.
Enjoy a polished ceiling appearance with continuous soffit-style lines, concealed fasteners, color options, and optional access panels for easy servicing when needed.
We can pre-wire and install recessed lighting, ceiling fans, heaters, entertainment wiring, or speakers to create a true outdoor room that feels comfortable day and night.
Most under-deck drainage systems can be added beneath existing decks after verifying spacing, slope, and framing conditions no major demolition required.
With occasional rinsing and periodic gutter cleaning, your under-deck system stays clean, functions properly, and maintains a sharp, finished look for years.
