UK homeowners are increasingly calling locksmiths as summer heatwaves cause doors to stick, warp or jam shut, with composite and patio doors especially affected by expansion in the heat. Bournemouth-based locksmith Alan Hickman, who covers the New Forest area, reports back-to-back callouts for jammed doors, alongside routine jobs like installing lockboxes for carers.
Why are heatwaves causing door problems?
Rising temperatures cause building materials, particularly composite doors and their frames, to expand slightly, which can throw locking mechanisms out of alignment or make doors difficult to close properly. Locksmiths say this is becoming a familiar seasonal pattern as the UK experiences longer and more intense periods of hot weather each summer.
Hickman, who works across the region near Ringwood and Eastleigh, described a typical day that included a customer whose patio doors would not close, likely due to heat-related expansion, alongside a separate job fixing a composite door with a broken locking function in Westbourne. His schedule also included installing a lockbox for an elderly client’s carer, illustrating the mix of heat-related emergencies and standard security work locksmiths juggle during hot spells.
It’s probably expansion issues with the frame causing the patio doors not to close properly, the locksmith said.
Are wildfires adding extra complications?
Yes, ongoing forest fires in parts of the New Forest have forced road closures, complicating travel for tradespeople trying to reach customers. Hickman noted he was avoiding the stretch between Ringwood and Eastleigh entirely because of fire-related closures, adding extra time and route planning to an already demanding workload during the heatwave.
Does cold weather cause similar issues?
Yes, extreme cold can also affect doors, though through different mechanisms than summer heat. While hot weather tends to cause materials to expand and jam locking mechanisms, winter conditions can lead to contraction, moisture-related swelling, or frozen components, meaning door and lock problems are not confined to summer months but can occur across seasonal temperature extremes.
