uPVC doors are extremely popular across Dundee homes because they’re durable, weather-resistant, energy-efficient, and secure. However, just like any frequently used part of your home, they can develop issues over time. Whether it’s a door that’s difficult to close, a handle that feels stiff, or a lock that just won’t turn smoothly, these problems can be frustrating — especially when they affect the security of your home.
In this guide, we’ll walk through the most common uPVC door problems seen across Dundee and how you can Repair uPVC door — plus when it’s best to call a professional for help.
Why uPVC Doors Need Maintenance (Especially in Dundee)
Dundee’s weather can be unpredictable — damp, windy, and cold during winter. Over time, temperature changes can cause uPVC door frames to expand, contract, and shift slightly. Daily use puts pressure on the hinges, locks, and mechanisms, which can eventually cause misalignment or stiffness.
A little maintenance goes a long way. Fixing a small issue early can prevent bigger — and more expensive — repairs later on.
Common uPVC Door Issues & How to Fix Them
1. Dropped or Misaligned Door
Symptoms:
- Door scrapes against the frame or floor

Cause:

DIY Fix:
- Open the door and locate the hinge adjustment screws.
- Use an Allen key to tighten and adjust the hinges.
- Test the door repeatedly while adjusting until it closes smoothly.
If the door still doesn’t sit correctly, the hinges may be worn out — this will likely require professional door realignment in Dundee.
