How to Adjust Cabinet Doors That Sag, Gap or Won't Close

Cabinet doors that sag, gap or slam usually need a few turns of the hinge screws. Which screw does what, when soft-close can be added, and when it is more.

The short answer

To adjust a cabinet door, work the hinge screws. On a typical European cup hinge, the front screw moves the door side to side, the rear screw moves it in and out, and the mounting plate sets it up and down. Most doors that sag, gap or won't close need this, not new cabinets.

Most kitchens reach a point where the doors stop closing flush. One door sits a little proud. Another slams instead of settling. The gap between two doors is wide at the top and tight at the bottom. It is easy to assume the cabinets are wearing out and start pricing a refresh. Most of the time, a screwdriver and a few minutes per door put it right. Cabinet repairs like these are some of my favourite small jobs.

What makes cabinet doors drift

Most cabinets built in the last few decades hang their doors on European-style cup hinges. The cup sits in a round hole in the back of the door, and the hinge arm clips onto a mounting plate inside the cabinet. Over years of use, hinge screws loosen with every open and close. Wood swells and shrinks through BC's wet winters and dry summers. The cabinet boxes shift a little as the house moves. Each change is tiny. Together they add up to doors that no longer line up.

How to adjust cabinet doors: up and down, side to side, in and out

Open the door and look at the hinge. Blum is one of the most common makers, and its own instructions for its CLIP hinges lay out the three moves below. Other brands work much the same way, though the screw spots can differ a little. Use a #2 Phillips or Pozi driver, and turn each screw a little at a time.

  • Side to side: turn the front screw on the hinge arm, the one closest to the door. This moves the door left or right and evens out the gap between two doors.
  • In and out: turn the rear screw on the hinge arm. This pulls the door toward the cabinet or pushes it away. It fixes a door that sits proud at the top or bottom.
  • Up and down: this lives on the mounting plate inside the cabinet. Some plates have a cam screw you turn. Others have screws you loosen, then slide the plate and tighten again.

Work one hinge at a time and close the door after every turn. When a door has two hinges, make the same move on both, or the door will twist. I adjust every door in a bank together, so the gaps match all the way along the run. When it is done, the whole kitchen looks planned again.

Can you retrofit soft-close hinges?

Often, yes. It depends on the hinge you already have. Blum says its hinges without built-in soft close can be retrofitted by clipping a BLUMOTION unit onto the hinge. If your hinges are Blum, that is the quickest route, and the door and cabinet stay as they are.

For other hinges, the cleaner fix is usually a new soft-close hinge matched to the holes you already have. I check the cup size and the mounting plate before I order anything, so the new hinge drops into the old spots. Doors with odd or very old hinges sometimes need a little more work. I tell you that at the quote stage, before any work starts.

Soft-close drawers

Drawers are the same idea. Some slides can take an add-on soft-close unit. Often the better fix is new full-extension soft-close slides. They close quietly, and you can reach what lives at the back of the drawer.

When adjusting is not the answer

Hinge work has limits. If the cabinet box is racked from a settled floor, no hinge setting will land the doors true. If a leak under the sink has swollen the side panel, the panel is the problem. If the hinge holes are stripped from years of slamming, the door may need a hinge plate moved or a small wood repair before screws will hold. I sort out which one you have on the visit, so the work fits the real problem.

Hardware swaps that lift the whole kitchen

If the cabinets are sound but the pulls feel dated, swapping every pull and knob is one of the cheapest visible upgrades in a house. Twenty pulls and ten knobs takes me about two hours. Match the new hole spacing to the old one, or plan to fill and re-drill.

I do this work all over the Fraser Valley. If you want it done for you, see cabinet repair in Langley or cabinet repair in Surrey for how I handle it in each town.

Questions on this one

  • Which screw moves a cabinet door up and down?

    On most European cup hinges, up and down is set at the mounting plate inside the cabinet. Some plates have a cam screw you turn. Others have screws you loosen, slide and tighten. The two screws on the hinge arm handle side to side and in and out.

  • Why is the gap between my cabinet doors uneven?

    One or both doors have drifted sideways. Turn the front screw on the hinge arm, the one closest to the door, to slide the door left or right. Make the same move on both hinges of that door so it does not twist.

  • Can I add soft-close to my existing cabinet doors?

    Usually. Blum makes a clip-on BLUMOTION unit for its hinges that lack soft close. For other brands, a new soft-close hinge matched to the existing holes is often the cleanest fix.
