Fast, professional, friendly service. Resolved tricky locked-in situation with very little damage to the door or frame, all of which was fixed before leaving.

Jonathan was everything I could ask for when I needed a new lock on my front door: responsive, quick, polite, effective and good value for money. I called him in the morning and by mid-afternoon, I had a new lock. I would definitely recommend.

I'd locked myself out of the house, he was with me in under 15 mins of calling and managed to open the door with no damage and quickly. Very happy with the service and speed
