Question? is your uPVC door lock mechanism working as well as it did when the door was first installed?

If it is thats fine, however there is a good chance that it is more difficult to engage the hooks and bolts or turning the key.

Upvc doors are designed to be draught free and secure, however as time goes by they tend to move out of alignment and need periodic maintenance to keep them in pristine working order to avoid uPVC lock repairs.

Possible problems

  • Handles need force to engage door lock
  • uPVC door won’t lock
  • Door catches on the frame at the bottom or side
  • Door latch doesn’t hold when you close the door
  • There is a small gap at the top of the door
  • The door is draughty.

All of these symptoms point to the door being out of line, it could be an issue with the door panel not being correctly fitted or with the way the door was installed. It is advisable to take action as it puts pressure on the locking mechanism.

If you have any of the above issues with your uPVC door, it can be professionally realigned and will work as it did before.
