uPVC and composite doors are on most modern homes, and their multi-point locking mechanisms are the single most common lock problem we're called out to. The good news: it's almost always fixable, and rarely means a whole new door.
How we fix a door that will not lock
We find the actual fault first. It is usually a worn gearbox, a failed cylinder or a door that has dropped out of alignment. We carry the common multi-point mechanisms and euro cylinders to fix most doors on the first visit. If your door has dropped or stiffened over time, we'll also adjust the alignment so it closes smoothly again.
Where a lock has failed completely and you're locked out, we can gain entry with minimal disruption and fit a new mechanism on the spot.

Common uPVC questions
That's usually a failing gearbox inside the multi-point mechanism. It's a very common fault and one we can normally repair or replace on the first visit.
Almost never. In the vast majority of cases we simply replace the internal mechanism or cylinder, which is far cheaper than a new door.
Yes, while we're there we can fit a British Standard, anti-snap euro cylinder to meet your insurer's requirements.
