Why dodgy doors are the latest casualty of the UK heatwaves 2026

Dodgy doors are becoming a common problem across the UK as heatwaves cause expansion and sticking issues. Locksmiths report a surge in calls for doors that won't open or close properly. This article explores why heat affects doors and what you can do about it.

Why Heatwaves Cause Dodgy Doors

The recent UK heatwaves have brought more than just uncomfortable temperatures—they've also brought a wave of door-related issues. According to Alan Hickman, a Bournemouth-based locksmith, calls about sticking, unopenable, or unlockable doors have doubled during the hot weather. The problem is most noticeable in areas where temperatures have been highest, as confirmed by Steffan George of the Master Locksmith Association.

The Science of Thermal Expansion

Doors are made from various materials, each reacting differently to heat. The simple physics of thermal expansion means that materials like uPVC and composite expand when heated, causing doors to swell and become misaligned. This expansion can make it difficult to lock or unlock doors, especially at the end of a hot day when the material has had time to heat up.

How Locksmiths Are Coping with the Surge

Locksmiths across the UK are experiencing a significant increase in heat-related callouts. The Master Locksmith Association's Facebook post on the topic received tens of thousands of views, indicating widespread concern. Many homeowners are left frustrated as their doors become impossible to operate during peak heat.

• Doors may need to cool down before they can be opened or closed.
• Regular maintenance can help prevent heat-related issues.
• Lubricating locks and hinges can reduce friction.
• Adjusting door alignment may be necessary after extreme heat.

Preventing and Fixing Heat-Related Door Issues

While you can't control the weather, you can take steps to minimize the impact of heat on your doors. Simple measures like keeping doors in the shade, using awnings, or applying protective coatings can help. If your door is already stuck, wait for it to cool down before attempting to force it, as this could cause damage.

Tips for Homeowners

Inspect your doors regularly for signs of warping or misalignment. If you notice issues, contact a professional locksmith who can adjust the door or replace faulty components. Investing in high-quality materials that are less prone to expansion can also be a long-term solution.

FAQ

In conclusion, dodgy doors are a direct result of the UK's recent heatwaves, but with the right knowledge and professional help, you can keep your doors functioning smoothly. If you're experiencing issues, don't hesitate to contact a trusted locksmith.
