Joanna and Chip Gaines really are the best home flippers around—and now they've proven their skills with homes on both land and water.

On this week's episode of HGTV's Fixer Upper, Joanna and Chip Gaines remodeled a Waco houseboat for Brett Swartz, a father of four, and the renovation was seriously amazing. With just $58,000, they completely transformed the 1970s residence, which Chip nicknamed "The Double Decker," according to HGTV.

Originally, the dilapidated $27,000 structure lacked any kind of aesthetic appeal, and Chip wasn't even sure if it would stay afloat after everything was said and done (spoiler alert: the houseboat floated in the end).

The houseboat may have looked like a lost cause, but it really just needed some TLC from the husband-and-wife team. On the exterior, Joanna gave the home a contemporary update by adding black siding and wood trim and planters. "Chip and Joanna really captured just the simple, subtle, modern design that I wanted," Brett told HGTV. "I didn't want anything flashy. I didn't want anything shiny. I just wanted it simple and I feel like they really got it perfect."

The interior renovations, which included updates to the living room, bathroom, kitchen, and upstairs bedrooms including a bunk room for the kids and a master bedroom for Brett, were just as remarkable. The new design featured floor-to-ceiling windows to provide wrap-around views, raised ceilings, and lots of white to make it feel bigger.

In the kitchen, even more windows provided a ton of natural white and access to gorgeous views.

And of course, the designer included shiplap, her signature material feature, but in a "skinnylap" style this time.
