   Beezo,

   Thee is no easy cure. Doing a spot or two form underneath is one thing, not the whole house. If you have carpet, pull it up and screw down through the subfloor. If you have particle board subfloor sink the screws as far as possible. Is your builder around. If the floor is not nailed to code he is responsible for it. If he wont respond to you you may have to call the licenes board in your state. How old is your house?

   *I forget what the name of it is, but I think there is a deck-building product that is basically a steel angle that you screw to you joists and then to the underside of the decking, so there are no exposed fasteners. Someone else will probably know what the name is. That's the simplest way I can think of.

   The product I think Nick is referring to is deck master. It is 2' strips of galvanized metal shaped to attach to the side of the joist and then angled out with holes on about 1"center to drive the screw into the flooring at a slight angle. I've used it and if the bottom side of the floor is accessable from the basement it wouldn't be so bad. Wouldn't reccomend it on low decks unless you have a midget on the crew.

   Deckmaster cost a bit, though. It costs a buck a foot or so. Also, it has a top flange that is supposed to go between the deckboard and the joist -- pounding that in would be a real treat. Lots of labor.

   You might first try running a good construction adhesive along the edge of a furring strip, pressing it up hard against the subfloor from below, and nailing/gluing it to the joist. This is a way to address squeaks, caused by rubbing of wood against wood ... but you didn't say what the exact problem is ... if the subfloor is moving, bending or buckling you have much more serious issues here.

   If the subfloor is popping up, my inclination would be to bring up the finished floor and do it right. If that's impossible & the finish floor is hardwood, explore driving screws through holes in the floor and plugging them. Just throwing out some random suggestions...

   *Here's a product that works well (if you are not doing a whole house). If you have lots and lots of floors to do, it would be best to remove the floor coverings and do the job right. It can get expensive, but it will be done right, and you won't have to keep messing with it.James DuHamel

   *Beezo,I agree with Rick and Andrew. Pull up carpet and nail, leave hardwood, tile, vinyl and glue, nail, and screw strips to the joists and subfloor from below.Tell us more, though. Where is the loser builder, and how did you find out?

   I have a house with almost every sheet of subfloor that was not nailed properly and no glue was applied to the joists. We cannot nail from above since floors are finished. Basement access is open. How can I draw the subfloor down tight and secure it?
