Fix squeaky stairs
A creaky step usually means the tread has worked loose and is rubbing against the riser or a nail. Screws from above or glued shims from below can pull things snug again. Set aside an evening and gather a few basic tools. Carpeted stairs can be fixed from above too, with a squeak kit that snaps the screw off just below the surface.
How a stair is built
Each step is a tread you stand on, resting on a riser (the upright board) and on angled boards underneath called stringers. When a tread loosens, it flexes a little under your foot and rubs against the wood or a nail, and that's the creak. Pulling the tread tight so it can't move is what quiets it.
Where on the step it squeaks tells you where to look. At the front edge, the tread is usually rubbing on the riser below. At the back, it's the riser behind. Near the sides, it's the stringers.
Why stairs squeak
The tread has come loose from the riser or stringer.
Old nails loosen and squeak as the wood moves.
Seasonal dryness opens small gaps.
Squeaks under carpet need a kit that screws through it.
| Squeak location | Likely gap | Fix |
|---|---|---|
| Front edge of the step | Tread to the riser below | Angled screws through the front edge, or shims from below. |
| Back of the step | Tread to the riser behind | Screws along the back edge into that riser. |
| Near the sides | Tread to the stringer | Screws down into the stringer, or glue blocks from below. |
| Under carpet, anywhere | Same gaps, hidden | A through-carpet stair squeak kit. |
Quiet the step
- Find the squeakStep slowly on each part of the tread: front edge, middle, back. Mark where it squeaks with painter's tape.
- From below: glue shims inIf you can reach under the stairs, tap glued shims into gaps between the tread and riser. Don't force them.
- From above: pre-drillDrill two small pilot holes at an angle through the front of the tread into the riser below, 6 inches apart.
- Drive screws or nailsDrive trim-head screws or ring-shank nails into the holes, then set the heads just below the surface.
- Fill and testFill the holes with matching wood filler and walk the step to check it's quiet.
Watch it done
- The step is quiet at the front, middle and back
- Screw or nail heads sit just below the surface
- The filled holes are flush with the tread
Squeak at the back of the tread? Fasten along the back edge.
If a step still creaks
Under carpet, use a stair squeak repair kit that drives a scored screw through the carpet and snaps it off below.
If the squeak is at the back of the tread, the gap is at the riser behind it. Fasten from above along the back edge.
What a pro typically charges (a rough estimate; prices vary by area): A handyman typically charges $100–$300 to quiet a few stairs.
