I highly recommend John from 1st Class Security. My colleague and I got locked in a property we were working in at around 6pm due to a faulty lock. I phoned John and he phoned back around 10 mins later to say he would be there in 30 mins. He actually arrived even quicker than he said. He managed to get the door unlocked and replaced the faulty lock for us and provided us with 2 new keys. He was so helpful and we are so thankful he was able to sort everything for us so promptly. Thanks John!
