No one likes hiring a locksmith when they have done the dumb key loss with no spares!!
However, Stephen is the man for the job should you be in this frustrating situation.
Trustworthy, prompt and professional. Job done smoothly, stress over! Thanks again Stephen

I contacted Steve regarding an issue with my tilt slide patio door, he gave me a price over the phone & came out the same day. Fabulous service & would highly recommend as most people give tilt slide doors a wide berth when it comes to carrying out repairs.

Stephen is a master craftsman at what he does. He talks you through and explains what and why the mechanisms have failed. He is easy to communicate with and provides you with the confidence you need, considering much of his work is likely to be related to your security and safety.

Stephen proved to be an absolute lifesaver after a spate of break-ins on our street. Responding promptly to my call, he upgraded my locks to anti-snap variants and also upgraded the locks on my old sliding patio door lock. His expertise and attention to detail was fantastic, ensuring not only a seamless installation but also providing invaluable advice on bolstering my home's security. Thanks to Stephen, I now feel significantly safer in my house.
