Expert UPVC Door & Window Solutions in St Helens by DB Locksmiths

UPVC and composite doors provide excellent insulation and security.

However, their internal mechanisms (multipoint locks) are complex and prone to wear over time.

If your door handle is floppy, stiff, or entirely jammed, you need a specialist.

Common UPVC Problems We Fix

• Jammed Mechanisms: The door is stuck shut and the handle won't lift. We can open the door without damaging the frame and replace the broken gearbox.
• Floppy Handles: The handle drops down when released, indicating a broken internal spring cassette or mechanism failure.
• Door Alignment Issues: The door drops on its hinges, making it difficult to lock. We can re-align the door by toe-and-heeling the glass panels or adjusting the flag hinges, preventing future mechanism damage.

Cost-Effective Repairs

Many customers believe they need a whole new door when the multipoint lock fails. This is rarely the case.

We carry dozens of different gearboxes and central mechanisms to repair your existing door quickly.

This provides a solution at a fraction of the cost of a replacement door.
