Almost all modern UPVC and Composite doors have complicated multi-point and high security locking mechanisms, unlike older wood doors with traditional cylinder and mortice style locks. They are normally always equipped with locking systems that can over time become misaligned. If not serviced correctly, UPVC and Composite doors can become so bad that you are unable to close the door and lock it.
Once you suspect a UPVC or Composite door is becoming problematic to close and lock or you are aware of any misalignment, its important that you get a professional out to check it over and realign it all so it works properly.
This complicated mechanism is all turned by a single key using a cylinder lock. As you can imagine it’s a complicated system that needs regular servicing as its only the pressure of turning the key that moves it. Servicing includes oiling / greasing using specialist lock oils / greases and verifying alignment of doors and adjusting hinges as necessary. We can perform one off maintenance or arrange regular servicing on commercial properties.
We recently changed some UPVC window handles to some newer more secure handles. It’s a very simple and quick job but it gives your windows a better cleaner more modern lock.
Make sure you keep your handles maintained, some simple WD40 applied every 12 months will do the trick and keep your handles working smoothly and reliably.
