The service
Get your UPVC door working — and secure — again
UPVC doors are heavy, and over time they can drop out of alignment so the locking points no longer meet the frame. That's when the handle gets stiff, the door is hard to lock, or the multipoint mechanism fails altogether.
We realign and adjust the door so it closes and locks smoothly, and where the gearbox has failed we replace the multipoint mechanism with the correct part.
While we're there, we can upgrade a vulnerable euro cylinder to a snap-safe one — a simple, worthwhile improvement to your door security.
What to expect
- Dropped doors realigned and adjusted
- Failed multipoint gearboxes replaced
- Euro cylinders upgraded to snap-safe
- Handles, spindles and keeps repaired
- Common parts carried; door left secure if ordering
- 12-month guarantee on the parts we fit
