Is Your UPVC Door Lock Mechanism Sticking?

A pvc door lock sticking can be very annoying and concerning and unfortunately, it is likely to get progressively worse if it is not fixed. It is important to carefully maintain UPVC door locks as they can be problematic. Sticky door lock issues should be addressed as a priority.

As an emergency locksmith in North London, experienced in UPVC door lock repairs, I come across jammed UPVC door mechanisms on a regular basis. This is a very common problem with PVC doors, especially in the summer months.

Why a UPVC Door Sticking is a Common Problem

A combination of factors can cause UPVC doors to stick and a common cause is the summer heat.

UPVC Door Expanding in the Heat

It is a common misconception that a PVC door is less likely to expand in the heat. On the contrary, we see expansion and movement in UPVC or composite doors more than we do in timber doors.

The Importance of UPVC Door Alignment

A PVC door that expands or moves, and is no longer correctly aligned, causes more problems than movement in a wooden door. UPVC door mechanisms rely on a number of bolts working in tandem, if one goes out of alignment they all do.

Realigning a UPVC door mechanism is not always straightforward and you need to know what you are doing.
