Flooring Contractor Surprise Cost

[Marek Berry]

I'm an out-of-state owner of a SFH in Austin, TX that is on the market to sell. Two weeks ago I had to repair the foundation and had to pull up all the laminate flooring. I was in town for the foundation work (a nightmare) and met with a flooring installer who speaks very little English. As part of the re-installation he said he'd need to level parts of the floor with concrete and I said that was fine. I left town and he completed the work.

Turns out he floated the entire home at a cost of $750, which I was not anticipating not did he communicate before hand. I didn't ask him to do the entire home, nor do I think it was necessary (but I'm open to being wrong). As mentioned there is a big language barrier, but from my perspective I was lead to believe it would only be a few bags. It might not be much $ to some of you and could actually be a great deal, but right now every penny counts for me and it's a lot when you're not anticipating it. 

I'm curious how you more experienced BP members would handle this situation? It's probably not enough money to worry about, but it's still something I'd like outside perspective on.

Thanks!
