Lorraine Windsor Managing Director, The Social Matrix
“I asked Security Masters Ltd to visit my home to carry out a security check and the service was excellent. Mark demonstrated to me how easy it would be to gain access to my home. He gave me sound advice and recommended changing the most vulnerable lock, rather than both of them. I have no hesitation in recommending Security Masters Ltd to anyone requiring either a security check or wanting to improve the security of their commercial or residential property.

Chris Metalle, Regional Director, London House.
“I recently had cause to ask Mark Radford of Security Masters to carry out some work for me and was impressed by the quality of his workmanship, his commitment to service and punctuality and his all round professionalism. I have no hesitation in saying that anyone choosing Security masters will be placing their work in very safe hands. He even provided me with a Harry Potter magic wand to allow me to gain access to areas that were hitherto barred to me.

“I just wanted to say a big thank you for the way you responded to my call out, I contacted you mid-day on Tuesday explaining that i had a couple of tenants in Manchester that couldn’t lock their front door from inside. They were very concerned and wanted the lock fixed immediately. Your man arrived later that day and solved the problem. Many thanks Mark for your prompt response to my call out.

I would like to recommend Mark Radford’s service from Security Masters.  My experience is that his service is very reliable and on time. I had a situation last week where one of the cleaners lost a property key and I needed Marks help.  He sorted out the problem, even with short notice, the lock was replaced and our client is happy again.
I have no problem to recommend Mark Radford’s service to anyone who may need his help.

Mr & Mrs Stewart – Blackheath

“Right from our first contact with Security Masters we received an exceedingly high standard of customer service that was helpful and knowledgeable. On installation the engineer was consultative, knowledgeable and made sure to clean up afterwards. Thankyou”

Mrs A Mclay, Mr D Hayde – Carlyle Property Managemen

“We recently asked you to undertake a security review of a property we manage in Blackheath, after an attempted break in at the property.

We were extremely impressed with the speed at which you responded to our request.  As well, you only recommended practical solutions to the situation, rather than suggesting we spend a lot of money on potentially unnecessary additions to the security that is already in place at the property.  The landlord was also appreciative of your suggestions.  You also quickly attended to dealing with the item we agreed to progress with, much to the tenants appreciation.

As property managers in SE London, we rely on service providers who are responsive and who provide an excellent service, just as we do for our clients.  Security Masters Limited totally meets our requirements in that regard. As well your pricing is very competitive with other similar service providers in the local market.

We highly recommend Security Masters Limited to any property owner needing simple or complex security solutions

Bruce Thomas, Valensole Inventories Ltd

“I was recently asked by my friend Joanne to be an emergency contact for her while she was away. Joanne has 3 dogs that were being looked after at her home by a dog sitter. The first day looking after the dogs the sitter could not manage to open the front door to the flat and rang me to help. I called Mark at Security Masters to Help. Mark responded very quickly and managed to get a very tough lock open in a short period of time to the immense relief of both the dog sitter and their owner who was in transit to her destination. Mark did a fantastic job and was very professional in his whole approach.”

Stacy Codling FDA, Managing Director, Dela Property Management.

“We asked Security Masters to provide an estimate to repair a faulty double glazed window mechanism. Mark was more than accommodating and called the tenant directly to arrange a viewing of the job. He went to the property the same day and called us straight away providing a diagnosis and price: affixed price with no “ifs” and “but” attached. just one fixed figure. Once the landlord authorised the amount, Mark was give instructions to proceed with the repair. He immediately contact the tenant directly to arrange a day and time to suit her.

The work was carried out quickly with no fuss or complication. The tenant took the time to tell us that not only was she happy with the repair but mark’s staff was polite and friendly. As the managing agent of the property. He kept us in the loop at each stage and proved himself most helpful. We shall continue to pass business onto Security Masters Ltd and encourage other property managers to do the Same.”

Lewisham East MP

“I am writing on behalf of my constituent and neighbour Mrs Sceats.  Mrs Sceats was a 93 year, housebound victim of a nasty robbery and as a result Victim Support arranged for a new back door and work to the front door.
Victim Support sent Security Masters who were absolutely excellent.  They arrived at 0830 and worked trough to 1400 and Mrs Sceats was so impressed she wished to thank them with a small gift of money, which they steadfastly refused.  Mrs Sceats herself can be quite determined but there was no moving on this because, they said, this was a government funded project.

I have to say I was very impressed indeed with their workmanship, professionalism and there ethical behaviour.  I’d like to pass on Mrs Sceats heartfelt thanks to you”

“Our neighborhood had been experiencing some strange goings on. Women were sitting in the back yard and strange men were just appearing in their gardens. With these stories becoming more common, I was only too happy to call Mark of Security Masters as I had heard all about his outstanding reputation and passion in securing peoples homes and subsequently their peace of mind.

Mark came to the property, examined the doors and windows and made recommendations for further securing the property. I found him to be knowledgeable and professional. He gave us a couple of options and once my sister and I had discussed it, Mark came round secured our home and I can really say that I do feel a lot safer.

Thank you Mark for the outstanding service you delivered. I have already been talking to my family about your work and will continue to do so.”

Mark & Carole Cress from Lee

Dear Mark,

Thank you very much for your recent email. We were very pleased with the prompt response and work carried out to our front door lock assembly. Our main concern was that we were in compliance with the latest fire regulations, the internet is a wonderful thing but it can give you information overload!!!!! I would not hesitate in recommending you or the company and hope to use your services again in the future.

Many thanks, Mark & Carole Cress..
