A small hydraulic damper catches the door in the last few inches and puts it down quietly. It sounds like a comfort feature and is mostly a durability one: nothing in the kitchen slams, so nothing gradually shakes itself loose.
Inside the hinge arm is a small cylinder of hydraulic fluid. As the door swings toward the frame the arm compresses it, and the fluid can only move through a restricted path, so the door slows over the last few inches and settles rather than banging shut. Runners work the same way at the back of a drawer.
The everyday benefit is quiet. The longer-term one is that nothing is ever shock-loaded. A door that slams for ten years works its screws loose, wears the hinge bores oval and stresses the joint between the frame and the panel, and none of that happens to a door that is caught.
It also has an adjustment. A tension screw on the hinge arm sets how fast the door closes, and a heavy door usually wants it slower than a light one. See the storage hub, pull-outs and door styles.

How it works
How Soft-Close Gets Fitted
Check what you have now
Older surface and semi-concealed hinges cannot take a damper. Those need concealed cup hinges, which means new bores in the door, and that is a permanent change we flag first.
Match the hinge to the door
Weight and overlay both matter. A heavy solid door on an undersized hinge sags, and a full-overlay door needs a different arm from a partial one. Neither is interchangeable.
Set the closing speed
The tension screw is set with the door hung rather than on the bench. Heavy doors want it slower, light ones faster, and it takes a minute per door to get right.
Return once they settle
Doors move slightly in the first month as the hinges bed in. A second visit re-adjusts speed and alignment, which is when most of the fine tuning actually happens.
When it wears
It Fails Gently, Which Matters
Quality hinges are rated for fifty to a hundred thousand cycles, which is roughly fifteen to twenty five years of normal kitchen use. That is a long time for a mechanism that gets used several times a day, and it is the reason the hardware is worth specifying properly rather than economising on.
What happens at the end of that is worth knowing: the damper stops damping and the door simply closes normally again. It does not seize, drop or jam. You lose the feature and keep the door, which is about the best failure mode a moving part can have.
Most complaints are not worn dampers at all. Doors that slam usually have a tension screw that has drifted, a loose mounting plate or screws that have pulled in the wood. All three are adjustments rather than replacements, and all three are why we return once after new doors or a reface settle, the same visit that fine-tunes handle alignment.

The Rest of the Hardware
Runners and hinges are half of it. These are the parts your hands meet.
How it works, how long it lasts, and what to do when a door starts slamming.
A small hydraulic damper inside the hinge arm catches the door over the last few inches and slows it to a stop. Soft-close runners do the same job at the back of a drawer box.
Quality hinges are rated for 50,000 to 100,000 cycles, roughly 15 to 25 years of normal kitchen use. Runners are similar. It is hardware you fit once and forget about.
The door starts closing normally again. It does not seize or drop. You lose the soft close and keep a working door, which is why a worn damper is an annoyance rather than a repair emergency.
Usually not. The tension screw drifts, mounting plates work loose and screws pull in the wood. All three are adjustments. A genuinely dead damper is the least likely of the four causes.
Sometimes, with a clip-on damper. Otherwise it means concealed cup hinges, which need new bores drilled in the door. That is permanent, so we point it out before the job is booked.
Yes, through the runners rather than the hinges. On a heavy drawer it is worth more than on a door, because a loaded drawer closing hard puts real force into the cabinet front.
Yes, and this is one of the few places we say that plainly. Cheap dampers fail early and the hinge is doing structural work as well, so it is not a component to economise on.
Set the closing speed on every door individually with them hung, not on the bench. The heavy pan drawer closes completely differently from the small ones.

One started slamming after a few months. They came back, turned a screw, done. Turned out to be the tension adjustment rather than a failure.

Explained that my old hinges could not take a damper and would need new bores. I would rather hear that than have someone bodge it.

Not the cheapest hardware and they were clear about why. The kitchen is silent, which after twenty years of banging doors is worth the difference.

Hardware that lasts, small adjustments, and what to check before calling anyone.
Hinge matched to door weight and overlay, closing speed set with the doors hung, and a return visit once everything has settled. Quoted with the rest of the work.
