The locking mechanism will fail after years of use, leaving you with a door that can not be opened or locked, but this does not mean you need a new door. SF Locksmiths specialise in uPVC door repairs in Doncaster.
We can save our Doncaster customers hundreds of pounds by replacing the faulty parts with genuine original materials, leaving your existing door feeling and working like new again!
A uPVC door is locked and secured by a “multipoint lock,” or mpl for short. You operate this mpl by lifting the handle and then locking the door in place by turning the key. When new, they work great, but after years of use, they do fail. The average length of time they last is 10-12 years.
Not at all; we have specialised in uPVC door repairs in Doncaster since 1999. We only repair doors, so we will not try to sell you a new door. If you visit a double glazing installer with your door problem, they reply that the required parts are no longer available. This could be true, but in nearly every case, we will have an alternative multipoint lock that will give the same security as before.
We are fortunate to have five suppliers with the most extensive range of multi-point locks available in Europe. Our mobile workshop is stocked to complete 99% of callouts on the initial visit.
We often get asked this question, but as an experienced locksmith, I know it will be fine. It will not involve removing the door from the hinges or any glass units. So, your door will suffer no damage. When the new mechanism is in, the door will work like it did when new, if not better. As part of the repair cost, the door will receive a full service and checkover.
Often, the main reason why a door locking mechanism does fail will be that the door has moved out of alignment. This will make it hard to lock the door. The locking points press against the door frame. High pressure on the door handle can wear out a lock prematurely when locking and unlocking.
We like to think so. Our knowledge extends to all doors, including patio, conservatory, tilt-and-slide, bi-fold and more.
There are many different types of mechanisms fitted to doors. GU, Advocet, Mila, Fuhr, Millenco, Fullex, Ferco, Yale, Winkhaus, ERA, and many others. We can supply and fit all these, carrying them to ensure we complete the repair on the same day we attend.
So, regardless of who fitted the door or how old it is, we can fix it call us for a free quote.

A new uPVC or composite door can cost £600 to £1,500. Getting a quote from Everest and Anglian would cost much more. Also, the “big boys” will try to sell you new windows at the same time.
It costs about £160-£210 to replace your existing mpl with a genuine one. It should last 10-12 more years. This price will cover all materials and labour and comes with a two-year guarantee. After servicing the door, we will check it for any other possible issues.
If the handles or lock barrels need changing, this can also be done. The costs are minimal and are often incorporated into the original quote.
We appreciate that the situation can be stressful and inconvenient. SF locksmiths have an emergency service for our Doncaster customers. They can repair your door the same day you call. And yes, we will turn up when we say we will.
