How to Inspect a Ladder Before Use: The Pre-Climb Check That Catches Real Faults

Inspecting a ladder before use takes under a minute and follows a simple order: feet, stiles, rungs, then any moving parts such as hinges, locks or ropes. You are looking for cracks, splits, missing or worn rubber feet, bent or twisted metal, loose rivets, and anything sticky, greasy or slippery on the rungs. If a fault turns up in any of those areas, the ladder comes out of service until it is fixed or replaced.

Why the pre-use check matters more than the annual one

Most ladder failures do not come out of nowhere. A cracked stile, a missing foot or a rung that has worked loose usually gives warning signs long before it lets go. The problem is that ladders live in garages, vans and side passages where nobody looks closely at them, and the damage that matters is often at ankle height where you never glance.

UK guidance from the HSE is that a ladder should be given a pre-use check by the person about to climb it, every time. That sounds like overkill for a homeowner painting a bedroom, but the check is quick and the failure mode is a fall from height.

Step 1: check the feet

Stand the ladder on flat ground and look at the bottom of both stiles. Every leaning ladder and step ladder should have rubber or plastic feet fitted, and both should be present, securely attached and still showing tread or grip texture.

• Missing feet mean bare metal on the floor, which slides on almost any hard surface.
• Feet worn smooth and shiny have lost most of their grip even though they look intact.
• Feet clogged with dried mud, paint or plaster dust behave like a worn foot.
• Splayed, torn or perished rubber usually means the ladder has been left outside for years.

Replacement feet are cheap and available for most mainstream brands, so this is one of the few faults worth fixing rather than binning the ladder over. If you cannot source the right part, retire it.

Step 2: run your eye down the stiles

The stiles are the two long side rails, and they take the load. On aluminium ladders you are looking for dents, bows, twists and any crease running across the rail. A crease across an aluminium stile is a serious warning sign because it means the section has already started to buckle, and it will fold at that point under load.

On fibreglass ladders, check for splintering, exposed fibres and chalky white surface bloom, which follows long UV exposure and weakens the resin. On timber ladders, look for splits running along the grain, knots near the edges of the rail, and any sign somebody has painted it. Paint on a wooden ladder is a problem because it hides cracks.

Step 3: test the rungs

Work up the ladder rung by rung. Each one should be firmly fixed at both ends with no movement when you try to twist it by hand. Rungs on aluminium ladders are usually swaged or riveted into the stiles, so any play at the joint means the fixing has loosened.

Then check the top surface of each rung for anything slippery. Wet paint, oil, silicone, grease and even a build up of polish will send a boot sliding, and it tends to be the rung you step on without looking that catches you out. Clean anything you find off before climbing, not after.

Bent rungs matter too. A rung that has been flattened or dished has taken a heavy impact, and that same impact went through the stiles.

Step 4: check the moving parts

This is where the ladder type matters. A plain leaning ladder has almost nothing to go wrong, but everything else does.

Step ladders

Open it fully and check that the spreader bars or restraining cords lock out straight and hold tension. A stretched cord or a bent spreader lets the legs creep apart under load. Check the hinges at the top for cracked plastic and missing rivets, and make sure the platform, if it has one, sits flat and locks down.

Extension ladders

Slide the sections and check the rung locks or hooks engage positively on both sides. Look at the rope and pulley if fitted, and check the guide brackets that hold the sections together are not cracked or loose. Uneven section movement usually means a bent guide.

Telescopic ladders

Extend the ladder fully and confirm every section shows its lock indicator engaged. Then retract it and check nothing is gritty or sticking. Telescopic ladders fail most often because grit gets into the sections and stops a lock from seating fully.

Step 5: check the labels

The rating label should still be readable. It tells you the standard the ladder was built to, its load rating and its class. A missing or illegible label does not automatically make a ladder unsafe, but on a work site it makes it unusable, and for a homeowner it means you are guessing at the load limit.

What to do when you find a fault

Do not put it back on the rack and make a mental note, because anyone else will grab it without knowing. Tag it or move it somewhere it cannot be picked up by accident. Feet, ropes and some proprietary parts are repairable with genuine spares. Anything structural, meaning cracked, bent, creased or split stiles and rungs, means the ladder is finished.
