Sticking uPVC Door: Locksmith or Window Specialist for Alignment?

A common and frustrating problem with uPVC doors is that the multi-point lock becomes difficult to engage, often requiring you to yank the handle or shove the door. This issue is usually rooted in door misalignment, but the question is: should you call a locksmith or a window specialist? While both can assist, a skilled locksmith should be your first call, as they can diagnose if the issue is alignment or a faulty uPVC gearbox.

The Locksmith's Role: Diagnostics and Mechanism Repair

A locksmith's primary expertise lies in the internal locking mechanism, which includes the gearbox, cylinder, and multi-point bolts.

• Diagnosis: A locksmith will first check if the lock engages smoothly when the door is open. If it does, the problem is misalignment. If it still jams, the problem is internal mechanism failure (which a window company won't fix).

• Gearbox Repair: If the key turns without engaging the lock, the internal gearbox—the heart of the multi-point system—is likely broken. A locksmith is trained to identify and replace this component efficiently.

  
  

The Window Specialist's Role: Frame and Seal Adjustments

A window or double-glazing specialist typically focuses on the integrity of the door and frame itself, including glass, seals, and hinges. They are ideal for:

• Hinge Adjustment: When a door has "dropped" due to gravity or weather (thermal expansion/contraction), the hinges need subtle adjustment to restore perfect alignment.

• Replacing Seals: Dealing with drafts or moisture ingress is their specialty.

  
  

Why a Skilled Locksmith is the Best Starting Point

A highly experienced locksmith, like Peters Locksmiths, is trained to perform minor hinge adjustments in addition to diagnosing and repairing the locking mechanism. This saves you the time and expense of calling two different trades. They will recommend a window specialist only if the door is fundamentally warped or damaged beyond adjustment.

Local Authority Check: We often see uPVC Gearbox Failures in the Dorset area, often disguised as alignment issues. Safety Tip: Always ensure your uPVC door is locked with the key, not just lifted on the handle, when you leave the house.
