Modern doors are designed to provide security, insulation and durability. However, even high-quality uPVC and composite doors can develop issues over time. At Secure Locksmith Cheltenham, we regularly attend properties where minor door problems have escalated, often due to poor workmanship or incorrect diagnosis.

Understanding the most common door faults can help homeowners act early and avoid unnecessary expenses.

 

Failing Lock Cylinders & Poor-Quality Locks

One of the most frequent problems we see involves worn or failing lock cylinders. Over time, internal components can deteriorate, making keys difficult to turn or causing the lock to jam completely. In some cases, poor-quality cylinders are fitted during installation, which significantly reduces lifespan and security.

As a professional locksmiths in Cheltenham, we assess whether a cylinder can be adjusted or if it requires upgrading. We supply and install high-quality replacements designed to improve both reliability and protection. Where needed, we carry out secure and efficient lock replacement, ensuring your property remains properly protected.

 

Composite Doors Dropping Over Time

Composite doors are popular due to their strength and insulation, but they are considerably heavier than standard uPVC doors. Over time, this weight places strain on hinges and locking mechanisms. As a result, the door can begin to drop slightly, leading to difficulty locking, misalignment or excess pressure on the gearbox.

The good news is that most of these issues can be resolved through professional adjustment. 

Our team regularly carries out upvc lock repairs and door realignment, preventing long-term damage to the locking system. When addressed early, these adjustments are straightforward and cost-effective.

 

Moisture & Poor Sealing Issues

Another problem we encounter is inadequate sealing along the bottom of the door. In heavy rain conditions, water can be drawn up into the door’s structure. Over time, this moisture absorption may cause swelling or subtle alignment issues, affecting how the door closes and locks.

A trained locksmith will recognise these signs immediately and recommend the correct course of action. Ignoring early symptoms can result in more extensive mechanical damage.

 

The Hidden Cost of Choosing the Wrong Locksmith

Unfortunately, not all locksmiths have the experience or training required to properly diagnose door issues. Many national call centres advertise locally but send subcontractors who may lack hands-on expertise. Inexperienced tradespeople may force mechanisms, replace unnecessary parts or misdiagnose alignment problems entirely.

What should have been a simple adjustment can quickly turn into avoidable damage and higher repair costs.

As an established local locksmith company in Cheltenham, Secure Locksmith focuses on honest assessment and long-term solutions. We prioritise repairing and adjusting where possible before recommending replacement parts.

 

A Recent Example from Cheltenham

We were recently called to a property where a homeowner had employed a locksmith to fix a stiff uPVC door that was only 18 months old. Instead of correctly adjusting the door – which had simply dropped slightly due to its weight – the previous tradesperson forced the mechanism and caused significant internal and external damage.

Most uPVC and composite doors will drop slightly over time, placing pressure on the locking mechanism. In the vast majority of cases, they can be adjusted properly with no long-term issues. However, due to poor workmanship, this relatively new door was too damaged and had to be completely replaced! A costly mistake to make! 

This situation highlights why it is always best to contact a reputable locksmith company. Choosing a genuine local expert, rather than a national call centre sending inexperienced subcontractors, often saves money in the long run.
