Symptoms
- One or more ladder feet don't touch the ground
- Ladder rocks side to side when climbed
- Ladder feels unstable even when apparently set up correctly
- Ground is sloped, soft, or uneven where the ladder needs to stand
Likely causes
- CommonGround slope or unevenness under the feetEven a small slope can leave one leg unsupported and cause rocking.
- CommonSoft or loose ground (dirt, mulch, gravel)Ladder feet can sink unevenly into soft surfaces under weight.
- PossibleLadder feet worn, missing rubber pads, or damagedWorn or missing non-slip feet reduce grip and stability.
- Less commonLadder not fully opened or locked (step ladders)An unlocked spreader bar lets the ladder shift under load.
What to do
- Stop and reposition rather than climbing a ladder that already feels unstable.
- Choose the flattest, firmest spot available; move the ladder rather than trying to force it to work on a bad spot.
- Use a manufactured ladder leveling accessory rated for your ladder type on sloped or uneven ground, not stacked boards or bricks.
- On soft ground, place a rigid, wide board under the feet to spread the weight and prevent sinking.
- Check that rubber feet are present, undamaged, and making full contact with the ground.
- For step ladders, confirm the spreader bar is fully locked open before climbing.
- Have a second person hold or brace the ladder's base whenever the ground can't be made fully stable.

When to call a pro
For work that requires standing on unstable or sloped ground repeatedly, consider hiring a professional with scaffolding or a lift instead of a ladder.
Safety
Use caution
Never improvise ladder height with stacked objects like boxes, bricks, or boards under the feet; use only rated leveling accessories, and always maintain three points of contact while climbing.
