Excellent service and communication. Mark was very friendly and polite and responded to queries promptly. Arrived on the day and on time as promised and installed a new lock and intercom system. Quality of work was excellent and at a very reasonable price too. Would definitely recommend.

We called Mark @Security-Masters to what we initially thought was a broken lock. Turned out much more complicated and time consuming. His advice was invaluable and helped us resolve the situation peacefully. Having waited around while the police negotiated, once inside, they worked quickly to change the locks and secure the premises. A huge thank you from all of us.

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!

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! Service: Security door locks
