What Causes uPVC Door Problems?
uPVC door issues usually stem from hardware wear rather than frame failure.
Common causes include:
- Worn multi-point locking systems
- Door dropping due to hinge wear
- Frame expansion in hot weather
- Shrinking rubber seals
- Poor installation
- Frequent heavy use
Multi-point locking strips are one of the most common components to fail.

Look out for:
- Difficulty locking or unlocking
- Door scraping the frame or floor
- Handle lifting but not engaging
- Draughts around the edges

If the handle moves freely but the lock does not engage, the gearbox may have failed.
