Do you offer UPVC Front Door Repairs?

Yes, we offer UPVC Front Door Repairs at fixed prices, including door adjustments & lock changes.


My door multi point lock has broken. Do I need a new door?
No, most times the multi-lock can be renewed regardless of the age on the UPVC door.


Why are my door handles really stiff to operate?

Although your door handles are stiff, the most likely cause would be a misaligned door.


The door bounces back open when I close it unless I lift the handle to keep it shut?

This could be due to either the latch part of the lock not working or the door being misaligned.


My door handles are loose wobbly floppy stiff or notchy?

The problem with loose wobbly floppy handles could be due to lack of lubrication, worn handles, as well as a broken springs or a faulty lock.


How do I know if I have an Aluminium (metal) or UPVC (plastic) or Composite door?
Measure the edge of the open door. Aluminium thickness is approx 30mm-50mm and in addition tends to have a wooden sub-frame. Whereas UPVC is approx 60mm-85mm in white or brown effect. In particular Composite doors are approx 44mm thick and can be almost any colour.


My door will not lock?
Just a re-alignment is required if the lock works when the door is in the open position.
