Upvc doors & common locking issues

Upvc doors & common locking issues

Locksmiths are so often called out to fix door lock problems, but with upvc doors, the issue may not be emanating from the lock itself.

Here’s what you need to know about pvcu door locks:

  • Like wood and aluminium, pvcu doors expand and contract
  • Even a couple of millimetres of change can put the door out of alignment
  • PVCu doors tend to have multiple moving lock parts, fitting into various apertures along the door frame
  • Any misalignment can prevent a pvcu door from locking or unlocking
  • If misalignment is the cause of the lock not working, then straightforward lock replacement will not be a long-term fix - the issue will keep recurring
  • Locking parts suffer from wear and tear in everyday use
  • Locking parts can get brittle and break with age

Double glazing door lock

Ground rules for faulty pvcu door locks - Double glazing door lock repairs Ipswich & Colchester

If you have a pvcu door lock which is broken, jammed or catching in even the slightest niggly way, you don’t have to live with it, you definitely don’t want to force it and you really shouldn’t ignore it.

Mr Misty The Window Doctor diagnoses the symptoms as: door handles which fail to release the key on trying to lock up; door handles which don’t spring back; loose door handles; stiff door handles needing undue pressure.  

Our skilled window and door double glazing engineers at Mr Misty can swiftly assess your faulty lock and take appropriate, cost-effective action to correct alignment issues and get it working properly again.

  • Don’t force the handle or lock
    It may cause additional problems resulting in extra costs - damaging the locking mechanism, door handle; marking door or frame.
  • Don’t let just anyone try to help
    The mechanisms are not obvious and there are many types
  • Don’t just leave it
    If the sticking lock or stiff handle is caused by heat or cold causing alignment issues between the door and the frame, it is liable to happen again. Get it looked at by a professional. If left, it might lead to a lock or gearbox failure – and that can be expensive to sort out when the lock fails with the door closed.
  • Don’t assume that it needs totally replacing
    Mr Misty’s experience and skilled hands and the right part may be all that is required.
  • Do plan to have your opening and locking windows and doors serviced
    A maintenance check can save £££s. Mechanisms may only require minor adjustments.
