A cabinet door that droops, rubs against its neighbor, or refuses to stay aligned can make an otherwise tidy kitchen look worn out. The good news is that many sagging doors need only a screwdriver and a few careful turns to sit straight again. If a hinge or screw is damaged, the repair may take longer—but you can usually spot the cause before you start.

Why Cabinet Doors Start Sagging
A cabinet door hangs from hinges that carry its weight every time you open and close it. Over time, repeated movement can loosen the screws that hold a hinge to the door or cabinet frame. A loose hinge lets the door shift, and even a small shift can make the gap look noticeably crooked.
Other causes include worn hinges, stripped screw holes, a loose hinge mounting plate, or a door that’s too heavy for its hardware. Sometimes the door isn’t sagging at all: it may be rubbing because the cabinet box or door has warped. Finding the cause matters. Tightening the wrong screw, for example, won’t fix a stripped screw hole.
What You’ll Need
For a basic adjustment, gather a screwdriver that fits your hinge screws. Many cabinet hinges use Phillips-head screws, but some need a Pozidriv or a different driver, so check the screw head before applying force. Using the wrong size can damage the screw and make the job harder.
Depending on what you find, you may also need a helper to support a heavy door, wood glue and toothpicks or a small dowel for a stripped hole, and replacement screws. Keep a small level nearby if you have one, but careful visual checks are often enough for a minor adjustment.
How to Fix a Sagging Cabinet Door
1. Check the door and hinges before adjusting anything
Open the door and look closely at each hinge. Check whether any screw is sticking out, whether the hinge moves when you gently lift the door, and whether the hinge itself looks bent, cracked, or badly worn. Also look at the gaps around the door: uneven gaps can help you tell whether the problem is height, side-to-side alignment, or how far the door sits from the cabinet.
If the door feels heavy or has two or more hinges, ask someone to hold it while you inspect or tighten the hardware. Supporting the door takes pressure off the screws and helps prevent it from dropping suddenly.
| What you notice | Likely cause | What to try |
|---|---|---|
| A screw turns without tightening | The screw hole may be stripped | Repair the hole or move the screw to sound wood |
| The door lifts or shifts when you touch it | A hinge or mounting screw is loose | Support the door and tighten the loose screws |
| The hinges look secure, but the gaps are uneven | The door needs alignment | Adjust the hinge screws if your hinges allow it |
| A hinge is bent, cracked, or won’t hold an adjustment | The hinge may be damaged or worn | Replace it with a compatible hinge |
2. Tighten loose hinge screws
Hold the door steady, then turn each loose screw clockwise with a hand screwdriver. Tighten slowly until the screw feels secure. Don’t force it: overtightening can strip the hole or damage the hinge, especially in particleboard or older cabinets.
Check both the door-side screws and the screws that attach the hinge or mounting plate to the cabinet. A hinge can look firmly attached to the door while its cabinet-side screws are loose. Close the door gently and check the gaps again. If it now sits level and opens without rubbing, you may be done.
3. Repair a stripped screw hole
If a screw keeps spinning and won’t grip, tightening harder won’t help. The wood around the threads has likely worn away, leaving the screw with nothing solid to hold. Remove the screw and hinge, then inspect the hole to make sure the wood isn’t cracked or crumbling.
For a small hole in solid wood, one common repair is to add a little wood glue and snugly fit in one or more wooden toothpicks. Let the glue dry fully, trim the excess flush, and reinstall the hinge screw. For a larger or badly damaged hole, use a properly sized wooden dowel and wood glue, then drill a new pilot hole after the glue has cured.
Cabinet materials vary, so take extra care with particleboard or MDF. These materials can break apart rather than hold a simple toothpick repair. A cabinet-repair plate or a new screw position in sound material may be a better choice. Whatever the repair, use a pilot hole and choose a screw that won’t poke through the cabinet wall or door.
4. Adjust concealed hinges
Many modern cabinets use concealed European-style hinges with adjustment screws. Depending on the hinge, these let you move the door side to side, forward or backward, and sometimes up or down. The screws and adjustment directions differ between models, so make small changes and watch what happens rather than assuming every hinge works the same way.
Start with the door closed. Turn one adjustment screw a little—about a quarter turn is a sensible test—then check the gap. If you’re correcting a door that sits too low, check whether your hinge model has a height adjustment on the mounting plate. On some hinges, height is changed by loosening the plate screws, moving the door carefully, and retightening them; on others, the adjustment works differently.
Make matching, gradual adjustments to both hinges when appropriate. If you move only one hinge too far, the door can twist and create a new problem at the opposite corner. Close the door after each small adjustment and compare the top, bottom, and side gaps.
5. Replace a damaged hinge
If a hinge is bent, cracked, badly corroded, or no longer holds its position, replacement is usually more reliable than trying to reshape it. Take the old hinge to a hardware store or compare its model and measurements with a replacement. Check the hinge type, opening angle, mounting style, and screw-hole pattern so the new one fits both the door and cabinet.
If possible, replace one hinge at a time while supporting the door. That keeps the door from shifting and makes it easier to use the remaining hinge as a guide. If the old screw holes are damaged, repair them before installing the new hardware. A new hinge can’t hold properly if its screws have no solid material to grip.
Can You Fix a Sagging Cabinet Door in Five Minutes?
Sometimes, yes. If the only problem is a loose screw or a small alignment issue on an adjustable hinge, the fix may take just a few minutes. You’ll need to identify the right screw, make a small adjustment, and check the door’s movement.
A stripped hole, damaged hinge, or warped door takes longer because it needs a repair or replacement, not just an adjustment. Treat five minutes as a quick-fix possibility, not a guarantee. Rushing a repair can strip the screws or leave the door more crooked than before.
How to Keep the Door from Sagging Again
- Check the screws occasionally. A quick look can catch a loose hinge before the door starts rubbing.
- Don’t overload the door. Heavy racks or organizers attached to the inside add weight and strain the hinges.
- Open and close the door gently. Slamming creates extra force on the hinge screws and mounting points.
- Use the right driver. A well-fitting screwdriver is less likely to slip, damage the screw head, or strip the hole.
- Replace worn hardware early. A hinge that’s visibly bent or loose can put extra stress on its partner.
Common Mistakes to Avoid
Don’t turn every hinge screw at random. Some screws attach the hinge, while others adjust the door’s position. If you’re unsure what a screw does, make a tiny test adjustment and see how the door moves before continuing.
Don’t use a power drill at high speed to tighten small hinge screws. It’s easy to drive too far, damage the wood, or strip the screw head. And don’t keep tightening a screw that spins freely. That’s a sign to repair the hole, not apply more force.
Finally, avoid assuming that every crooked door has the same cause. If the hinges are secure and the door still rubs, check whether the cabinet frame is out of square or the door has warped. A badly warped panel may need professional repair or replacement rather than hinge adjustment.

Frequently Asked Questions
Which screw should I turn to raise a cabinet door?
It depends on the hinge. Some concealed hinges have a height adjustment on the mounting plate, while others require loosening the plate screws and repositioning it. Check the hinge design and make small adjustments so you can see exactly what changes.
Why does my cabinet door keep sagging after I tighten it?
The screw hole may be stripped, the hinge may be worn or bent, or the door may be too heavy for the hardware. If the screw turns without gripping, repair the hole or use a suitable mounting plate instead of tightening harder.
Can I use longer screws to fix a loose cabinet hinge?
Sometimes, but measure carefully first. A longer screw can reach sound wood, but it must not pierce the cabinet wall or door. If the hole is badly damaged or the material is particleboard, a repair plate or another repair method may hold better.
Do I need to remove the cabinet door to fix it?
Usually not for a loose screw or a small hinge adjustment. You may need to remove it to replace a hinge or repair a stripped hole. Have someone support the door while you remove hardware, especially if it’s wide or heavy.
Conclusion
Most sagging cabinet doors come down to loose screws, poor alignment, a damaged hinge, or a worn screw hole. Start by checking the hardware, then tighten or adjust it in small steps. If a screw won’t grip or a hinge is damaged, repair or replace the faulty part rather than forcing it. A careful fix can restore a straight, smooth-closing door—and help it stay that way.
