Why Choose Us

On your uPVC window, multi point mechanisms, levers, springs and ball bearings over time will wear and eventually malfunction or break.

We have found that many people in the past have had entire multi point locking mechanisms replaced unnecessarily when all that needed was to repair or replace certain sections of the multi point lock.

Our approach is to ensure we provide you with the most cost effective solution. The uPVC window mechanism will once again provide a smooth operation and ensure your security.

Layered Protection

If your window is not locking smoothly we advise a quick test that can be undertaken by yourself and only takes a few seconds. At the window that is not locking smoothly, open the window. Whilst open, lift the handle up (this should engage the multi point locking mechanism).

Window Alignment

It is important to correct alignment problems. SheffLOCK who will know exactly how to realign your door. Attempting to resolve the problem yourself without the required knowledge and experience can quickly make the situation a lot worse.
