Every misaligned kitchen door is one of four problems, and only one of them is actually a hinge problem. The reason this matters is that the hinge is the only one of the four with an adjustment screw, so the hinge is what gets adjusted regardless of the real cause. If you have adjusted the same door more than twice, the hinge is not what is wrong with it.
What Are the Four Causes of a Misaligned Shutter?
They present differently, and separating them takes about five minutes with no tools.
| Cause | How it presents | Fix |
|---|---|---|
| Hinge out of adjustment | Door is flat, gap is wrong but even along its length | Adjust. Holds |
| Hinge fixing lost grip | Door drops again within weeks of each adjustment | Dowel repair at the fixing |
| Shutter has warped | Door touches at top and bottom but not the middle, or rocks | Replace the shutter |
| Carcass out of square | Gap tapers along its length. Drawers in the same unit bind too | Re-level and re-fix the box, or rebuild |
The distinguishing question is whether the gap is even or tapered. An even gap in the wrong place is a hinge. A gap that is wider at one end than the other is geometry, and no hinge adjustment will take out a taper.
How Do You Work Out Which One You Have?
Four checks, in this order. Each one rules something out.
One. Is the gap even? Look along the gap between the door and its neighbour, or between the door and the carcass. Hold a coin or a pencil at the top of the gap and then the bottom. Same width at both ends means the door is sitting parallel and the problem is position, not geometry. Different widths mean something is out of square.
Two. Is the door flat? Close it and look along the face from the side. Then open it and lay a straight edge across the back. A door that touches at top and bottom but gaps in the middle has bowed, and no adjustment fixes a bowed door.
Three. Do the drawers in the same unit work? If the drawers in that cabinet bind at a consistent point as well, the cabinet is out of square and the door is only the most visible symptom. This is the single most useful check on the list.
Four. Press the base panel. Empty the cupboard and press the bottom. A softened base is why a cabinet goes out of square in the first place, and it is far more common than people expect. Our guide on swollen kitchen base panels covers what you are feeling for.
What Can a Hinge Adjustment Actually Correct?
More than most people realise, and that is worth knowing before anyone suggests replacing anything. A standard concealed hinge adjusts in three directions independently.
| Direction | What it corrects |
|---|---|
| Side to side | The vertical gap between two neighbouring doors |
| Up and down | A door sitting low or high against its neighbour |
| In and out | A door standing proud of the run, or sitting recessed |
What adjustment cannot do is take out a taper, straighten a bowed door, or make a door fit an opening that is no longer rectangular. Those are the three situations where adjustment feels like it is working and then does not last.
One practical note: on a run of several doors, adjusting one in isolation often makes the next one look wrong. A run should be set as a run, working from one end, which is why a fitter will often adjust six doors to fix a complaint about one.
Why Does the Same Door Keep Dropping?
Because the adjustment is holding but the thing it is bolted to is not. This is the most common pattern in an older kitchen and it is routinely misread as a hinge quality problem.
A hinge transfers the door's weight into a few screws in engineered board. Each swing works that board a little looser. Once the grip has gone, the hinge can still be adjusted, and it will hold the new position for a while, but the fixing continues to move and the door drops again. Adjusting it again compresses what little material is left, so each cycle is shorter than the last.
The test is to back one screw out by hand and see what comes with it. A clean screw in a firm hole means the fixing is sound. Board dust and fibres mean the hole has stripped and needs a dowel repair rather than another turn of the adjuster. Hinges pulling out of the board goes through the repair options and which ones last.
Treat a third adjustment on the same door as a diagnosis rather than a maintenance task. The door is telling you something has worn out, and continuing to adjust it is the reason people end up replacing a shutter that could have been kept.
What If Every Door in the Run Looks Wrong?
Then look at the floor and the wall rather than the doors. A run of base units is levelled at installation, and if that levelling has shifted the whole run tilts slightly, which shows up as gaps that are consistent in direction across several doors.
Three causes are worth checking before anyone touches a hinge.
- Plinth packing has moved or compressed, often where the floor is not flat. Common in older flats
- A wall fixing has pulled, letting the tops of the units move forward while the bases stay put
- The countertop was fitted onto an unlevel run and is now holding the units in a slight twist
These are carcass and installation issues rather than door issues, and correcting them often brings every door back into line at once without replacing anything. It is also the reason a survey measures the run rather than looking at the door someone complained about. Walls and floors in Bengaluru apartments are rarely true, which the guide on walls that are not straight explains in more detail.
When Does a Misaligned Door Mean Replacement?
In two situations, and neither is about the alignment itself.
The first is a warped shutter. A bowed door cannot be adjusted flat, and the bow usually comes from moisture getting into one face of the panel, which means it will continue. That is a shutter replacement, and it is worth checking the others on the same run because the cause is often shared.
The second is a carcass that has gone out of square because the base or lower sides have softened. Here the door is fine and the box is the problem. Re-levelling a box standing on a failed base panel does not hold, because the plane it is standing on is still moving.
In both cases the useful question is not whether to replace the door. It is whether the rest of the carcass is sound enough to carry new shutters, which is a measurement question settled at survey and set out in the kitchen carcass check. Where the boxes pass, new shutters and hardware over the existing carcass is usually the better value than a new kitchen.
Frequently Asked Questions
Why will my kitchen cabinet door not close properly?
One of four things: the hinge is out of adjustment, the hinge fixing has lost its grip in the board, the shutter has warped, or the cabinet has gone out of square. Only the first is genuinely a hinge problem, and it is the only one with an adjustment screw, which is why the hinge gets adjusted regardless of cause.
How do I tell a hinge problem from a carcass problem?
Look at whether the gap is even or tapered. An even gap in the wrong position is a hinge and adjustment will hold. A gap wider at one end than the other is geometry, and no amount of hinge adjustment takes out a taper. Also check whether the drawers in the same unit bind.
What can a hinge adjustment actually fix?
A concealed hinge adjusts in three directions: side to side for the gap between neighbouring doors, up and down for a door sitting low or high, and in and out for a door standing proud or recessed. It cannot take out a taper, straighten a bowed door, or make a door fit an opening that is no longer rectangular.
Why does the same door keep dropping after every adjustment?
The adjustment is holding but the board the hinge is screwed into is not. Each swing works that board looser, so the hinge holds its new position for a while and then moves again. Each cycle gets shorter. Back a screw out: board dust coming with it means the hole has stripped.
How many times should a door need adjusting?
Treat a third adjustment on the same door as a diagnosis rather than maintenance. Continuing to adjust compresses what little material is left in the screw hole, and it is the reason people end up replacing a shutter that could have been repaired with a dowel at the fixing.
Every door in my kitchen looks slightly off. What causes that?
Usually the levelling of the whole run rather than the doors. Plinth packing that has moved or compressed, a wall fixing that has pulled so the tops move while the bases stay, or a countertop fitted onto an unlevel run that is now holding the units in a twist.
Can a warped kitchen shutter be straightened?
No. A bow comes from moisture reaching one face of the panel, so it continues rather than settling. The door needs replacing, and it is worth checking the others on the same run because the cause is usually shared between them.
Do I need a whole new kitchen if the cabinet is out of square?
Usually not. If the box went out of square because its base panel softened, that panel needs replacing. If the levelling or a wall fixing moved, re-levelling and re-fixing often brings every door back into line without replacing anything. The question is whether the carcass can carry new shutters.
Key Takeaways
- Four causes, one adjustment screw. That is why the hinge gets blamed for all four.
- An even gap in the wrong place is a hinge. A tapered gap is geometry.
- If the drawers in the same unit bind too, the cabinet is out of square.
- A hinge adjusts three ways, but it cannot take out a taper or flatten a bow.
- A door that drops after every adjustment has a stripped fixing, not a bad hinge.
- Treat a third adjustment on the same door as a diagnosis, not maintenance.
- Every door looking slightly off points at run levelling, not at the doors.
- A warped shutter cannot be straightened because the cause continues.
Before replacing any shutter, settle whether the boxes behind them are sound. Run the kitchen carcass check, or see kitchen shutter replacement in Bangalore.
