How do I keep cabinet doors from sagging?
Check the hinge screws twice a year and snug any that have loosened before the holes strip. Do not hang anything on the doors, keep the door's weight off the hinges, and keep indoor humidity steady so wood doors do not warp. Heavy or tall doors benefit from an extra hinge.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Test each door
Open each door and press down on its outer corner. If the hinge or the cabinet frame moves, the screws have loosened.
Step 2: Snug the hinge screws
Use a hand screwdriver on every hinge screw on the door and the cabinet, and stop as soon as each is snug.
Step 3: Fix any stripped hole early
If a screw spins freely, fill the hole with toothpicks dipped in wood glue, cut them flush, let the glue dry and redrive the screw.
Step 4: Touch up the alignment
On a concealed hinge, turn the mounting plate cam screw a quarter turn at a time to bring the door back level.[1]
Step 5: Take weight off the door
Remove towel hooks, bag holders and anything else hung on the door, and move heavy items off any shelf that pushes against it.
Step 6: Add a hinge to tall doors
On a tall or heavy door with two hinges, add a third in the middle, drilling a pilot hole for each screw and using the same hinge type.
Step 7: Keep humidity steady
Run the kitchen exhaust fan while cooking, wipe up spills at the sink base, and avoid placing a door against a steaming dishwasher or kettle.
Step 8: Put it on the calendar
Repeat the test every spring and autumn, when wood is changing with the seasons.
The best protection against sagging is a short check twice a year. Tighten any loose hinge screw before it strips its hole, keep weight off the door, and keep the kitchen's humidity from swinging. Sagging starts small and gets worse every time the door opens, so the cheapest repair is the one you do first.
Why doors start to sag
A cabinet door hangs from its hinges on a few screws set into the cabinet frame. Every opening and closing pulls on those screws a little. Over the years they work loose, the hole around each one wears, and the door drops at its outer corner. Heavy doors, wide doors and doors used many times a day lose the race first.
A screw's grip depends on how much thread is in sound wood. The Forest Products Laboratory says "the withdrawal load varies directly with the depth of penetration of the threaded portion and the diameter of the screw."[3] When the hole wears, that grip falls away, which is why a loose screw tightened too hard makes the problem worse. If a door has already dropped, how to fix a sagging cabinet door covers the repair.
The twice-a-year check
Open each door and press down gently on its outer corner. If the hinge or the frame moves, a screw is loose. Use a hand screwdriver, not a drill, on every hinge screw on the door and on the cabinet, and stop as soon as each is snug. A drill makes it easy to strip the hole.
If a screw turns freely, do not keep tightening. Fill the hole with a few toothpicks or a short dowel dipped in wood glue, cut them flush, let the glue dry and redrive the screw.
Concealed hinges also let you correct small drift before it shows. Blum's instructions for its CLIP hinge say to rotate the cam screw on the mounting plate to adjust the door position (+/- 2 mm).[1] On a one-piece wing plate, loosen the screws on the mounting plate, adjust the door to position and tighten the screws (+/- 3 mm).[1] Turn a quarter turn at a time and look at the gap along the top and side before you turn again.
Keep weight off the door
Towel hooks, bag holders and wire racks add weight at the point where the door has the most leverage. Move them to the wall or inside the cabinet. Check that a full shelf is not leaning on the back of the door, and that a door is not being used as a handle to pull open a stuck drawer below it.
For a tall or heavy door that has only two hinges, a third hinge in the middle shares the load. Use the same type of hinge, mark the position with the door closed, and drill a pilot hole for each screw. If the door is already warped, an extra hinge will not make it flat.
Keep humidity steady
Wood doors and frames move with the air around them. The Wood Handbook puts it plainly: "Wood in service is always undergoing slight changes in moisture content."[2] A finish does not stop this, because protective coatings can retard dimensional changes in wood but do not prevent them.[2] Differential shrinkage caused by differences in radial, tangential, and longitudinal shrinkage is a major cause of warp.[2]
In a kitchen, that means a few habits. Run the exhaust fan while you cook, wipe up water at the sink base straight away, and avoid parking a kettle or slow cooker under a door that closes against a steam source. Doors beside a dishwasher vent and a range hood are the most likely to move.
Stop and call a pro if
- Several doors sag at once. That usually means the cabinet box has racked or the wall has moved, and fresh hinge screws will not hold.
- The frame is soft or crumbling around the screws. A cabinetmaker can add a hardwood backer or rebuild the mounting point.
- A door is warped or cracked. A new matching door is often the cleaner repair than adjusting the hinge.
- Water damage reaches under the sink. Swollen particleboard does not tighten back up, and the leak needs fixing first.

Common questions
- How often should I check my cabinet hinges?
- Twice a year is enough for most kitchens. Open each door, press down on its outer corner and tighten any hinge screw that moves. Doors used constantly, such as the one under the sink or the pantry door, can be checked more often.
- Does hanging things on a cabinet door make it sag?
- Yes. Towels, bag holders and wire racks add load at the outer edge of the door, which pulls on the top hinge screws every time the door opens. Use a hook on the wall or inside the cabinet instead.
- Do heavy cabinet doors need more hinges?
- Tall and heavy doors usually do better with three hinges than two, because the load is shared. Use the same type of hinge as the existing ones and drill a pilot hole for each screw so the cabinet frame does not split.
- Why do cabinet doors sag more in older kitchens?
- Years of opening and closing wear the screw holes, especially in particleboard cabinet boxes, so screws loosen. Fixing the hole early with glued toothpicks or a dowel stops the door from dropping further.
- Can humidity make a cabinet door sag or warp?
- It can contribute. Wood takes up and gives off moisture all the time, and a door that swells or bows can pull on its hinges and make the gaps uneven. Steady humidity, a working exhaust fan and quick clean-up of water near the sink help.
