On Monday night's episode of the reality renovation show, the couple's builder Dave quit and walked off site after being accused of cheating by foreman Keith.
Courtney and Hans' kitchen floor has to cross into a hallway to match up with their living and dining area, so Keith was concerned that Dave was getting a head start on hallway week when laying the flooring.
And even though Dave is following common building practice, Block rules state that you can't start on another room before it's designated week.
After a fiery row, Keith says that Dave needs to be re-inducted.
Not happy with that, the builder decides he 'doesn't want to play the game anymore'
A tearful Courtney says, “He’s the best builder in Australia, probably the world."
The flight attendant later said, "I was like, I can not believe that this is happening. All over a stupid floor... I was like, 'Keith, you're dead to me.''
However, after an emotional goodbye, Dave and Keith worked things out, all was forgiven, and the 'best builder in Australia' returned to the show.
