So glad I checked this site to find a Locksmith after my Aunt had a break in. From my phone call & speaking to Lawrence he attended in a hour. Made safe the window & checked the door, which he will be back to change the lock once ordered. Such a helpful man, reasonable rates & I couldn’t recommend him highly enough. Thank you Lawrence.Verified reviewerJob location: N910 Quick, skilful and kind

Laurence was very professional and went above and beyond our expectations. He provided clear information on the issue, resolved it and even helped us out with another issue we had with another door. He was transparent about the cost (no hidden fees!) and provided really excellent communication overall.Verified reviewerJob location: SW1610 My window was not opening
