household has 4 young children and a small dog. Would you install 8 mm laminate in living room, great room, hallways and master or would you install ceramic tile? They already have tile in the wet areas so the new tile will not match well with existing tile and they can't afford to replace it all. Home is located in SW Florida thanks for any ideas

OK my wife and i are getting ready to buy our hardwood floors on Friday. We are not sure if we are going to go with the Bamboo or Oak yet...all depends on price. So this past week I have ripped up the carpet, the padding, all the trim and staples. I screwed down the sub flooring to eliminate any moving of the plywood. I have one board (4x8) sheet that is not level. All 4 corners of the board are in level with the boards around it but in the middle it sags about a good 1/8-maybe 1/4" max. I can tell the joist are level and good because the rest of the room is level and flat, just by looking at the plywood you can see that it looks warn out...main flow of traffic from kitchen to the living room. The house is only 5 years old. We are putting down wood floors in the living room and two bedrooms - all upstairs. I cant get to that sheet from under because of it being a finished living room/bulk head. Would bracing the joist help? My question is should i go with a self leveling material over just that one board or should i just cut it out and replace it with a new sheet? I am going home tonight to sand all the butt joints with a belt sander and then I believe the sub floor is prepped for wood floors. I plan on nailing the wood froor down. Any info will be helpful. Thanks. Kirt
