If your uPVC or composite door is stiff, won't lock properly, or the handle feels loose or jammed, it usually does not mean you need a new door. In many cases, the fix is repairing or adjusting the parts you already have, like the multipoint mechanism, gearbox, cylinder, keeps, hinges, or handles.
We repair, replace, and realign uPVC door locking systems for homeowners — saving you money, preventing costly door replacements, and keeping your property secure.'
We provide complete uPVC door and multipoint lock repairs for all types of domestic doors:


Multipoint locks have several locking points and internal parts that can wear out, especially the gearbox and locking strip. We diagnose what's actually failed and repair or replace only what's needed.
If the door drags on the frame or won't lock cleanly, alignment is often the real culprit. We adjust the hinges and keeps so the door closes and locks smoothly again.
Loose, floppy, stiff, or non-springing handles are common. Replacing the handle (or addressing a worn internal spring setup) can prevent bigger mechanism failures later. We can replace common uPVC and composite lever handles and match common finishes.
When a handle won't open the door, it's often not the handle. Common causes include a jammed multipoint mechanism/gearbox, a dropped door creating pressure on the strip, a sticking cylinder, or weather-related stiffness.
We also handle repairs on:
Usually not. Realignment and/or a mechanism repair is often enough.
Yes. Alignment and locking performance go hand in hand, so the mechanism is inspected and tested.
In many cases, yes. Handles come in common styles and finishes, so matching is often possible.
