I have a contractor who installed prefinished hardwood flooring. When I slide my sock from side to side, it's very smooth. However, there are some spots when I slide my sock up and down that are uneven.
He says, worst case scenario, he will sand the whole thing down smooth and refinish.
I'm happy he's willing to do that, but seems a little extreme. Is there anything else he can try to get it smooth? The floor is already down.
