Under-Deck Drainage Systems in Slinger, WI
If you’ve got a second-story deck—or you’re thinking about building one—you’re sitting on a big opportunity. With the right waterproofing system, the space below your deck can be more than an afterthought. It can become a dry, usable outdoor room you’ll actually want to spend time in, no matter the weather.
At Hometown Builders Unlimited, we design and install under-deck drainage systems that protect your home, extend the life of your deck, and double the ways you enjoy your backyard.
Why Waterproof Your Deck?
Without proper protection, water seeps through your upper deck boards and into the joists below. Over time, that leads to rot, mold, and structural issues—not to mention a soggy, unusable space underneath. Our under-deck drainage systems stop that from happening, giving you a clean, dry area to use however you like.
Under-Deck Drainage Systems
Our go-to waterproofing solution is an under-deck drainage system. Think of it like gutters—but for your deck. It catches rain and snowmelt before it can soak into the framing or fall through to the space below.
Once installed, the space under your deck stays completely dry—perfect for storage, seating, or even a full outdoor room. You’ll be able to add lights, fans, furniture, and more without worrying about the weather.
Key Benefits:
- Keeps your lower space clean and dry
- Protects framing and joists from moisture damage
- Extends the lifespan of your entire deck
- Makes the space below more functional and comfortable
- Pairs perfectly with composite decking systems
Flashing & Sealing
To fully waterproof a deck, the edges matter just as much as the top. That’s why we use flashing seals where your deck meets your home. This added detail helps prevent leaks, keeps water out of the walls, and adds an extra layer of durability to your upper structure.
Finish the Look With a Deck Ceiling
Once your under-deck area is dry, finishing it with a ceiling can take it to the next level. Whether it’s a simple clean soffit-style ceiling or something with built-in lighting and speakers, we can design a finished look that ties your whole outdoor space together.
Use the Space. Don’t Lose It.
With a dry, protected area beneath your deck, you can finally make the most of every inch of your backyard.
Use it as:
- A covered seating area
- An outdoor kitchen or grilling zone
- A kids’ play space
- Dry storage for lawn gear, bikes, or furniture
- A quiet corner for reading or working
- Even just a clean place to escape the sun or rain
And the best part? You’ll spend less time dealing with repairs and more time enjoying the space.

We waterproof both wood and composite decks. If you’re building new, we’ll help you choose the right material and install a system that protects it from day one. Already have a deck?
