Squeaky floors
Tools: drill/driver, stud finder, hammer, nail set · Materials: trim-head screws or a squeak-repair kit, wood shims and construction adhesive (from below), talcum powder or graphite (hardwood)
Steps
- Walk the floor and mark each squeak with tape; have someone step on it while you listen from below if you can access the joists.
- From below: where the subfloor lifts off a joist, tap a shim coated in adhesive into the gap — snug, not forced, or you create a hump.
- From above on carpet: drive a trim-head screw through the carpet into the joist at the squeak with a squeak-repair kit, then snap the head off below the surface.
- From above on hardwood: work talcum powder into the joint between boards and walk on it to lubricate rubbing edges.
- If a board flexes, drive a finishing nail at an angle into the joist, set it below the surface, and fill the hole.
Stop and call a pro if
- the floor sags or bounces as well as squeaks — a joist or subfloor problem
- the subfloor is damp or shows staining from below
- the squeak is in a bathroom or kitchen floor that feels soft
What a pro does that you can't
A handyman or carpenter re-secures the subfloor from above with the finish protected, sisters a weak joist, and replaces water-damaged subfloor around fixtures.
DIY cost: $10–35 for a squeak kit or shims
