Feisty twins Alisa and Lysandra Fraser have downed tools for the last time and vowed never again to appear on the The Block.
The finale of the The Block: Fans v Faves will screen on Wednesday when the winners and the financial windfall of each of the four competing couples will be revealed.
The pair pocketed $395,000 after winning The Block: Sky High in 2013 and as far as the sisters are concerned, even if they don't make a cent at the auction, Wednesday cannot come quick enough.
Having appeared on the Nine Network reality series two years in a row, they just want to concentrate on two building projects and their new online homewares store, Alcollections.com.au.
"It's it. I'm done," Alisa told AAP.

"We're working on two big projects in Melbourne and it's pretty much another Block without the bulls***."
Alisa and Lysandra joined former Block renovators Brad and Dale and newcomers Chantelle and Steve and Kyal and Kara in a series which pitted experienced contestants against novices.
The four teams have renovated Dux House at 47 O'Grady St in Melbourne's Albert Park which was built in 1912 and once screened silent flicks.
It was purchased by The Block's producers for $5.85 million last March.
After months of renovating, there are now four plush apartments within the old brick facade, car parks and an indoor heated swimming pool.
The apartments are tipped to sell in the vicinity of $2 million each when they are auctioned on Tuesday, ahead of Wednesday's final episode.
Just how much money each team wins will be determined by what reserve price each apartment is set at. The contestants get to keep any money over the reserve price.
Alisa said if the reserve price is greater than $1.5 million then it's quite possible one team or even all four will not make any money.
She doubts if all four premises will all get near their $2 million price tag and she expects one of them to fail - hopefully not theirs.
That's why the reserve price on each apartment is crucial to the outcome of each couple making a decent profit.
"There's never been a situation where there has been four properties going out on the same day in the same area for near $2 million ... so it depends what they set the reserves at," Alisa said.
"If they set it at $1.5 million we should all make money.
"If they set them higher than that then we most likely won't."
She called their apartment the "ugly duckling" of the sale because "it's the only one that doesn't have city views".
However, the twins put more money and effort into designing the kitchen, dining and living area than the upstairs section of the apartment.
"The kitchen and living dining area was the most important to us and there's no denying our downstairs is the most impressive and our selling point," she said.
"We are the only ones with a separate living and dining room and with an apartment this size that's an important thing.
"They can't do that (set our reserve higher), because it looks better downstairs, we are in the worst position in the building and the only one without city views."
The twins weren't afraid to air their grievances during the taping of the series or let loose with F-bomb tirades on the way they were judged.
Alisa had no regrets about what she said or their actions and reactions.
She said what was portrayed on screen was only a snapshot of a day renovating Dux House.
"We're reactive people and we've always been ourselves and wear our heart on our sleeves ... no one can understand it until they have been under that pressure," she said.
"There are 24-hours in a day and only 40 minutes of it get's shown on TV."
She said they will learn on Monday what reserves have been set for each of the apartments which go under the hammer on Tuesday.
* The Block finale will screen on Wednesday, April 4 at 7pm on the Nine Network.
