We turn the wasted space under elevated decks across Nashville and the surrounding counties into dry, usable patio, with the drainage and ventilation planned so the framing holding it all up stays sound.

Dry Below, Dry Above
Keeping the space below dry is the easy half. Keeping the frame dry is the half that matters.
Under any elevated deck there is a room’s worth of space doing nothing but collecting mowers, mud, and whatever blew under there last fall. A drainage system turns that into covered patio for a fraction of what building the same square footage would cost. There is a right way to do it and a way that costs you a deck frame.
There are two approaches. An under-joist system hangs a ceiling below the framing and drains water out to a gutter. It is the less expensive one and it can be retrofitted to a deck you already own. The tradeoff is real though: water still runs between your deck boards and across the joists before those panels catch it, so the framing keeps getting wet and still has to be able to dry out. An above-joist system installs during a build or a re-deck, with a membrane or trough over the joists so water never touches the framing at all.
“A ceiling under a deck is not the same thing as a roof over the frame.”
Either way, the framing has to breathe, so we vent the perimeter instead of sealing the underside up tight, run the gutter somewhere water can actually go, and grade the ground below so your new dry patio is not sitting on wet clay. And if your deck sits low to the ground, we will tell you it is not a candidate. Low decks need cross ventilation underneath, and closing one in is how the boards end up green.
What We Build
Under-deck options we design and install
Which of these fits comes down to one question: are we working under a deck you already have, or one we are about to build?
Under-Joist Ceiling & Drainage
Panels and a gutter fitted below your existing framing, so the space underneath goes dry without touching the deck surface above. The practical retrofit, and the one most homeowners with a deck already up end up choosing.
Above-Joist Drainage Systems
A membrane laid over the joists before the boards go down, so rain never reaches the framing in the first place. It has to be planned into a new build or a re-deck, which is exactly why we bring it up before the boards are ordered.
Finishing The Space Below
A finished ceiling, recessed lighting, a fan, and a real floor under your feet instead of dirt. This is the part that turns a dry area into a room people choose to sit in, and it is where the space stops feeling like storage.
No. You need enough height to lose roughly a foot to the ceiling and still walk under it comfortably, which in practice means a deck off a main floor or a walkout basement. Decks sitting close to grade are better left open, because the airflow under them is doing a job.
It is the cheapest square footage you will ever add.
The space is already there. It already has a roof, which is your deck. It needs no footings, no posts, and no addition to your house. All it needs is somewhere for the water to go and a reason to want to be down there, and you get a shaded spot that works in the middle of a July afternoon when the deck above it is too hot to stand on.
We are a local crew that builds under-deck drainage and dry space across Middle Tennessee, and we will tell you when your deck is not the right candidate, with one point of contact from your first call through the final walkthrough. No subcontractor shuffle, no surprise line items.
