I had a problem with my door not closing properly without a key or extreme force. Mark quoted and then arranged for replacement parts and called me as promised to arrange the repair work. On repair day, he was very quick and efficient. Thank you very much and for accommodating my schedule!read more

Excellent service from Mark at Security Masters. He replaced a faulty deadlock and sashlock on our backdoor, with the locks keyed alike. It was a quality job - the door closes and locks much better than it ever has!read more

I had a job involving a door that needed specific fire regulation knowledge and I couldn’t even find anyone to quote for it. After tearing my hair out for weeks, I found Mark at Security Masters. Mark understood exactly how to do the job correctly to fire regs and proceeded to order the required doorset and complete the job. He was always responsive and always arrived exactly on time. He was thorough, professional and knowledgeable. I’m extremely happy that I found Mark, and couldn’t be more grateful.read more

Mark and David from Security Masters arrived on time, they were very efficient, knowledgeable and friendly. The best thing about my experience is that I now feel more secure, which is a feeling you can't really describe, but goes to your bones. My house, which means everything to me, is safe when I'm in it, and when I'm out. I would recommend Security Masters to anyone who wants their property to be safe and secure, and who wants a 5 star customer service. Many thanks to Mark and David for doing an excellent job.read more

Mark from Security Masters attended my rental property to investigate a fault with the main front door. It was a pleasure dealing with Mark. He identified the problem quickly and gave me clear options as to how to proceed. My tenants are delighted with the work he has done and, after my experience with other locksmiths, I was relieved to receive an invoice which matched his quotation with no hidden extras. I would certainly recommend Security Masters. Work is completed to the highest standard. They are extremely professional, efficient and trustworthy.read more

Mark from Security Masters visited our property to carry out a security audit and demonstrated to us exactly where our home was vulnerable to burglars. He gave us really sound advice and advised us which locks needed upgrading. We had the locks upgraded and the wooden front door reinforced to prevent the door being forced, all for a reasonable cost. We can highly recommend Mark and Security Masters for their friendly professionalism, knowledge and expertise.read more

Smart Locks

Smart locks allow you to automatically operate them remotely. They can be operated in conjunction with smart doorbells, e.g. the Ring Doorbell. For example, you could see that a carer is at the door and remotely let them in, so that your loved one doesn’t need to.
