I have roughly 600 sq ft of basement that needs new flooring after some unfortunate flooding this past summer. We had carpet over concrete and are now looking to lay vinyl planks down. There is about 150 sq ft off to the side (L-shaped basement) that is very uneven.
I'm a first time home owner, inexperienced with these types of jobs, and just trying to figure out the best way to approach this.
Do we try to level out the higher area only? Grind it down, or self leveling concrete? Or lay down a subfloor throughout the entire basement?
The majority of the floor is even, with one section that was possibly a crack in the foundation "repaired" by a previous owner. Max variation is nearly 1/4" in some spots around the edge of that patch. They had laid some ugly VCT over top to try and hide it.
And yes, the water problem has since been solved. And if it makes a difference, the area that has the raised patch is not the area we had water issues.
Any advice is greatly appreciated!
