Yeah I'm only halfway reading thru this so what I said really doesn't make sense. It's been a long day lol. I've seen my share of cheap glue down installs gone bad.....at RiteRug it was the 50 percent rule. 50% of the time the installer would start install on schedule, 50% of the time it was done right, 50% of the time RiteRug wouldn't take rightful blame and would stick the customer with the bill. The fucking stories I could tell.......
OP, this stuff is easy enough to do yourself, even with no experience. Google/youtube is your friend
