How to Estimate Labor Hours vs Material Units for Laminate

Floor squeaks occur when loose subfloor plywood rubs up and down against framing nails. To fix squeaks: 1) From below (basement access): have someone walk above to locate movement, tap a wood shim coated in carpenter glue into the gap between joist and subfloor (never force it wide), or drive short 1-1/4" screws through subfloor into the hardwood; 2) From above: use a Counter-Snap / Squeeeeek-No-More kit to drive scored breakaway screws through carpet or hardwood into the joist, then snap the screw head off flush below the wood surface.
