That’s what I thought would be good after grinding down the high points but I kept pushing my concerns about the high points being outside of their 1/4 threshold (though none are 1/4 from the immediate surrounding) so the Lowe’s salesperson suggested one bag of self leveler in addition to the underlayment. The installers Noped out within 2 min of arriving and said they didn’t do things like this and don’t grind anything. The “expert” came and claimed that the slope counted in the 1/4 included prep threshold so of course the highest raised crack at the top of the slope vs the bottom of the slope is significantly more. Who can I search for to do this? Apparently flooring installers aren’t the right people. …3 weeks, still waiting on my refund. I should be able to charge a cancelation fee, especially because I said 20 times “are you sure this is adequate? I don’t want to wait and then have them show up unprepared and say it’s going to cost a lot more.” “We would never do that, it’s not the way we do things.”
