Why Your uPVC Door Won’t Close Properly (and How to Fix It Safely)

If your uPVC door is suddenly hard to close, feels stiff when locking, or needs a bit of a lift to shut, you’re not alone. It’s one of the most common problems homeowners face, especially with older doors. While it can be frustrating, it’s usually caused by minor alignment issues that are quick to fix.

At MK Doors & Windows, we specialise in uPVC door repairs across Milton Keynes, helping homeowners restore smooth operation and proper sealing without the need for full replacement.

Common Reasons a uPVC Door Stops Closing Properly
Several factors can cause your door to drop or go out of alignment:

  • Weather changes: Heat expansion in summer or cold contraction in winter can shift the frame slightly.

  • Hinge wear: Over time, hinges loosen or sag under the weight of the door.

  • Misaligned locking strip: The door’s multi-point locking system can move out of place, preventing a clean close.

  • Seal shrinkage: Flattened or shrunken seals stop the door from compressing properly.

  • General wear and tear: Everyday use naturally affects moving parts, especially in older installations.

The good news is that nearly all these problems can be fixed quickly with a professional service and adjustment.

What Happens If You Ignore the Problem
It might be tempting to just slam the door a little harder, but forcing it closed only makes things worse. Misalignment increases pressure on the hinges and locking mechanism, often leading to broken parts or even frame cracks. You could also lose valuable heat through small gaps, raising your energy bills unnecessarily.

Getting your door serviced early prevents damage, improves insulation, and keeps your home secure.

How We Repair a Door That Won’t Close Properly
Our experienced team inspects the door carefully to identify the exact cause. Most repairs include:

  • Adjusting hinges and strike plates for a perfect fit

  • Lubricating locks and handles to restore smooth movement

  • Replacing worn hinges, locks, or seals where needed

  • Checking the alignment of the door sash and frame

  • Testing closing pressure to ensure a tight seal

Once realigned, your door should close easily with minimal effort, and you’ll instantly notice reduced draughts and better insulation.

When It’s Time to Replace Instead of Repair
Most uPVC doors can be repaired and realigned with no problem, but if your door is cracked, warped, or over 20 years old, replacement may be more cost-effective long-term. We always provide honest advice and clear options so you can make an informed decision.
