I should add and not trying to slam Heartland, When I removed the vinyl flooring, I did not see nor find many screw attaching the floor (OSB) to the Joists. I'm not sure what method they use. I can feel a big difference in the floor when walking from the Kitchen to the living area. Heartland may only attach the OSB around the perimeter and through the cabinets??? The flooring I used was from Home D and was $3.67 a ft. I used a little over 3 boxes for the kitchen. Including trim, total cost was about $200.
