Fast arrival and Fast Job. Took no time to get here on a Sunday afternoon. Into the property in no with zero damage to anything. Very friendly guy who even adjusted our Yale lock and a few bits of great advice. Can highly recommend.



Great service provided by Pete. He came out within the hour to change 2 locks for me and whilst he was doing this he spent a long time sorting out the door to close neatly, it had never been aligned properly. He was friendly and professional, really impressed and grateful to Pete, highly recommend.


Fantastic service. Pete was with us within 2 hours (despite not being an emergency) and sorted out 3 door locks for us efficiently and cleanly. Would highly recommend. Many thanks.


Very friendly and professional service, thank you for your help with our door!


Came out within 1/2 hour of calling the team. Thought this would be a quick job. Unfortunately the front door frame warped and the door needed realigning, they did an absolute brilliant job and did not finish until it the door was perfect. Really impressed, with workmanship, tidiness and knowledge. I would definitely use again and recommend highly to anybody – a stellar job sir

I would highly recommend Pete at C&D Security. He responded very rapidly to our call, attended when he said he would, solved the issue quickly and with a minimum of fuss and didn’t charge an extortionate price. We would very definitely use him again.
