Quick Summary
Hinge adjustment is the least expensive alignment repair, while a failed gearbox or multipoint mechanism costs more because the parts are dearer and the labour longer.
- A gap that widens at the bottom hinge side means the door has dropped and needs alignment.
- Adjustment will not hold if a hinge is cracked, the frame has moved or the sash is warped.
- Fix the alignment before the mechanism, or a new lock part will fail the same way.
- Ask any tradesperson to separate alignment work from general repair work before they quote.
What uPVC Door Alignment Repair Cost Actually Covers
The cost of uPVC door alignment repair depends on what has actually failed, not on how the door feels when you push it.
Homeowners ring up convinced they need a new door when the fault is a hinge that has slipped or a gearbox that has failed.
Why alignment is priced separately from a general door repair
Alignment is a distinct job with a distinct cause. The door has moved out of square, usually through hinge wear, loose fixings or a failed hinge pack.
That is different work from swapping a handle or replacing a lock cylinder. It takes longer, needs the right tools, and the price reflects that.
Here are the cost benchmarks the article cites, and what each one actually covers.
| Item | Cost stated in article | Note |
|---|---|---|
| General uPVC repair work | Covers handles, seals, glazed units; not an alignment price | |
| Realignment and hinge adjustment | Sensible benchmark for this kind of visit | |
| Hinge adjustment | Least expensive alignment repair | Usually no new parts needed |
| Hinge replacement | Modest part cost, longer labour | Needed when a hinge is worn or cracked |
| Gearbox or multipoint replacement | More than a hinge adjustment | Parts cost more and labour is longer |
| Lock change on its own | Lower end of the range | Ask for mechanism cost separately |
uPVC Door Not Closing Properly: Diagnosing the Cause Before You Pay
A uPVC door that will not close properly is usually suffering from one of three faults: hinge misalignment, a swollen or damaged frame, or a failed lock mechanism holding the door off the keep. Diagnosing which one you have takes ten minutes and saves you paying for the wrong repair.
- Look at the gaps. Stand inside and check the gap between the door sash and the frame at the top, bottom and both sides. An even gap all round means the door is square.
- Check the bottom corner. A gap that widens at the bottom hinge side means the door has dropped. That is alignment.
- Try the handle with the door open. If the handle turns freely with the door open but jams when closed, the lock is fighting the frame. That is alignment too.
Checking the frame gap and the sash
The frame gap is your best diagnostic tool. Run a finger or a thin card around the perimeter of the closed door.
A sash that sits proud at the top and tight at the bottom has dropped. That is a hinge adjustment job nine times out of ten.
What most guides miss is that a sticking door is not always an alignment fault.
uPVC Door Hinge Adjustment: The Cheapest Fix When It Fits the Fault
Hinge adjustment is the least expensive alignment repair, and it is the right fix whenever the door has simply dropped or drifted out of square. A technician adjusts the hinge pack to lift the sash back into position, then checks the lock lines up with the keeps.
How a hinge adjustment actually works
Most uPVC doors hang on two or three adjustable hinges. Each hinge has small grub screws or a cam that moves the sash in two directions: horizontally (side to side) and vertically (up and down). A technician loosens the locking screw, turns the adjustment screw a quarter-turn at a time, and tests the door after each change. The aim is to close the gap at the bottom hinge side without over-tightening the top corner.
A common pattern is that the door has dropped at the handle side because the bottom hinge has worn or the fixings have loosened. Adjusting the bottom hinge lifts that corner; adjusting the top hinge pulls the top corner in. Getting the sequence wrong makes the door bind at the lock side, so the order matters.
When adjustment will not hold
Adjustment is not a permanent fix if the underlying cause is structural. Watch for these signs:
- The hinge is visibly worn or cracked. A hinge that has lost its pin or has a cracked leaf will not hold an adjustment. It needs replacing, not tweaking.
- The frame has moved. If the frame is out of square, often after settlement or a damp issue, adjusting the hinges will pull the door back for a few weeks and then it will drift again.
- The sash itself is warped. A door that has absorbed moisture and bowed will not sit true no matter how the hinges are set.
A proper visit checks the frame and the keeps as well as the hinges, so you are not paying twice for the same fault.
Watch Out Forcing a sticking door shut puts strain on the lock mechanism and the frame. Stop pushing it and get it looked at before a hinge adjustment turns into a lock repair.What you should expect to pay
A straightforward hinge adjustment is usually a quick job because it needs no new parts in most cases. If a hinge has failed and needs replacing, the part cost is modest but the labour is longer. Ask the technician to confirm before the visit whether the price covers adjustment only or adjustment plus any hinge replacement, so there are no surprises.
uPVC Door Lock Repair Cost: When the Problem Is the Mechanism
Lock repair becomes the cost driver when the mechanism itself has failed, not the alignment.
The parts that fail most often are:
- The gearbox, the central unit that drives the locking points
- The multipoint strip, which runs the length of the door edge
- The cylinder, which can fail or be snapped in an attempted break-in
Replacing a gearbox or multipoint mechanism costs more than a hinge adjustment because the parts are more expensive and the labour is longer.
If the lock has failed because the door has been out of alignment for months, fixing the lock without fixing the alignment means the new part will fail the same way.
uPVC Door Repair or Replacement: How to Decide
Repair is the right call in the large majority of cases. A door that has dropped, sticks, or will not lock is almost always fixable, and the repair costs a fraction of a replacement door and frame.
Replacement starts to make sense when:
- The frame itself is cracked, bowed or rotten
- The door has been damaged in a break-in beyond the lock and frame edge
- The glazed units have failed across multiple panes and the door is old
For landlords and letting agents, the repair-first route also matters for compliance.
A realignment and a mechanism repair will outlast most replacement quotes you will be given.
What a Professional Alignment Visit Includes
A professional alignment visit starts with a full inspection of the door, frame and mechanism, then moves to adjustment and testing.
A proper alignment job differs from a quick tweak that fails within weeks, and the difference lies in what the technician actually does during the visit.
1. Diagnosis before any adjustment
The first job is to establish why the door has moved. That means checking the frame for movement or bowing, the sash for square, and the hinges for wear or loose fixings. A technician should also check the keeps and the lock mechanism, because a door that will not lock is not always an alignment fault. Skipping this step is the most common reason a cheap adjustment fails.
2. Gap check around the full perimeter
The frame gap is the diagnostic tool. Measuring the gap at the top, bottom and both sides confirms where the door has dropped and how much adjustment is needed. An even gap all round means the door is square; a gap that widens at one corner tells the technician which hinge to adjust first.
3. Hinge adjustment or replacement
Once the cause is known, the technician adjusts the hinge pack to lift the sash back into line. If a hinge is worn or cracked, it is replaced rather than adjusted. The order of adjustment matters: bottom hinge first to lift the dropped corner, then the top to pull the sash square, testing the door after each change.
4. Keep adjustment
The keeps are the metal plates the locking points engage with. If they are out of position, the lock will not engage cleanly even after the hinges are set. Repositioning the keeps is part of a proper alignment visit, not an optional extra.
5. Mechanism and lock test
The technician checks the handle, gearbox and cylinder operate without strain, and confirms the door locks and unlocks smoothly. If the mechanism has failed because the door has been out of alignment for months, that is a separate repair and should be quoted separately.
6. Full cycle test and cause explanation
A good technician opens, closes and locks the door several times to confirm it holds, then explains what caused the misalignment so you can stop it happening again. That explanation is part of the value of the visit.

Frequently Asked Questions
How much does it cost to realign a uPVC door?
There is no single figure, because a realignment is priced on the fault rather than the door. A straightforward hinge adjustment is the cheapest outcome, while a dropped sash that needs toeing and heeling sits at the higher end. Ask for a pre-agreed price before work starts so the figure reflects your door, not a generic estimate.
Can I adjust a uPVC door myself?
Some homeowners do manage a basic hinge adjustment with an online tutorial, and it is a reasonable option if the door is only slightly catching and the hinges are the visible adjustable type. The risk is misdiagnosis: turning the wrong screw can pull the sash out of square and make the lock miss its keeps entirely. If the door has dropped, the lock is stiff, or the frame gap is uneven top to bottom, stop and get it inspected. A failed adjustment often costs more to put right than the original repair would have.
Will realigning a uPVC door fix a stiff lock?
Sometimes, and that is exactly why diagnosis matters. A lock that has become hard to turn is often fighting a misaligned door, with the gearbox and keeps no longer lining up. Realigning the door restores that line and the lock frees up. But if the gearbox itself has failed, or the cylinder is worn, alignment alone will not solve it and the mechanism needs repairing or replacing. A locksmith should test the lock through the full swing before quoting, so you are not paying for alignment that was never the cause.
Is it cheaper to repair or replace a uPVC door?
Repair is almost always the cheaper route when the door leaf, frame and double glazing are sound. Alignment, hinge, seal and lock mechanism faults are all fixable on an existing door. Replacement becomes the sensible choice when the frame is distorted, the glazed units have failed throughout, or repeated repairs keep returning to the same fault. Get the door inspected first: a repair-first approach means you only replace when the structure genuinely will not hold a repair.
Can a locksmith repair a uPVC door that will not close?
Yes. A locksmith who works on uPVC and composite doors can diagnose why the door is not closing, whether that is a dropped sash, worn hinges, a slipped mechanism or a misaligned keep. Many visits resolve the problem on the day with an adjustment, and parts such as hinges or a gearbox can be replaced where needed. Confirm before booking that the locksmith covers door alignment as well as locks, and ask whether a warranty applies to the parts and labour.
