A squeaky noise in your wood laminate floor isn’t a serious problem, expect perhaps for your sanity. The squeak simply means that part of the floor isn’t secured firmly enough, causing the floorboards to move against each other when weight is applied. The solution is to resecure them. This works for nailed or glued laminate floors, but don’t do it for "floating’’ floors, which aren’t supposed to be secured.
Locate and mark each squeak on the floor by walking slowly over and listening carefully. At each point where there is a squeak, mark an "X" with a piece of chalk. Work methodically from one end of the room to the other.
Load a pilot bit into your power drill. Walk across the floor again, this time drilling pilot holes at each point where there is a chalk mark. If any of the marks are right on the seam between two floorboards, don’t drill on the mark, but slightly to both sides of it. Do all the marks on the floor.
Take the pilot bit out of your drill and put the screw driver bit in. Get a handful of galvanised wood screws. Sink one screw for every hole, driving them straight down and getting the screw heads slightly below the surface of the wood.
Scoop up a little wax putty with your plastic putty knife and press in into each hole. Press it down firmly, packing it in fully so there’s a little mound of wax putty over the hole, then push the flat front edge of the knife over the mound to cut it off and make it flat with the floor.
Immediately buff the putty with a cotton cloth to remove any excess putty. Repeat for each screw hole.
