Solid Hardwood, Engineered and Laminate Flooring - Laminate problems - I may be blonde, but I'm not stupid, I don't think!

I am hoping someone can give me some valued advice. I recently had Mohawk Dura-Lock Plus laminate "professionally" installed in my kitchen. The installer, who was a crotchety ol' fart, came over to the house a week before to measure the layout. He did not at that time evaluate the floor for levelness, moisture, and overall condition. With the exception of an obvious 12.00"x12.00" floor rot repair on the floor near the wall, the floor looked fine. He never questioned the work that was done, and really didn't care. He came back the next week to install the floor. He installed the flooring as fast as he could, without any underlayment because he said, with two layers of vinyl tile beneath, it was not necessary(Mohawk confirmed this) He also did not apply water to the tongue and grooves to activate the adhesives(Mohawk has said he should have done this). After he left, I noticed a "bubble" in the floor by the area that had been repaired. I complained to the carpeting company, and they spoke to the installer. The installer said that there was nothing he could do to fix this small area. He did not know the floor was going to be un-level in that area. He claims the floor is unlevel due to the house settling and the joists warping. ( he never went into the crawlspace to verify this). He said to fix this bubbled area would cost $1000's of dollars because the whole floor would need to be ripped out, joists to be replaced, then elevated including the cabinets. He said to lay in subfloor cement filler in this dipped area, would only be a temporary fix and that eventually that would all crumble away. I believe that this man, can
come back and remove 5-6 panels, and fix this dip in my floor thats causing the boards to warp. I believe that he can use something, foam, filler, sand, his underwear for all I care, to level out this small area that lies not far from the wall. Before I go back and bang on their door again, I was hoping that there may be someone who can give me some expert advice. Can anyone help?

Here is some advise, or an observation...


Your getting hosed!!!!

They accepted that subfloor as Ok. Now make them do it right, or refund your money!!!
