10 Lock Repair
Posted 1 day ago
Good, reliable service
Lawrence arrived at my house within 30 minutes of me using the Checkatrade website. He was very polite on the phone and didn't charge any call out fee. He was upfront and honest about what needed to be done. He couldn't fix the problem with our lock immediately and needed to order parts, but he did this quickly and always communicated with me clearly about pricing, ordering items and how long it would take, He came back 3 days later, at the arranged time (which he swapped around for my convenience), and fixed the lock quickly. He remained polite and friendly throughout. Would recommend.Verified reviewerJob location: NW910 Locksmith

Excellent service from start to finish!
Lawrence arrived promptly, was friendly, professional and clearly very knowledgeable. He replaced my broken door spindle quickly and efficiently, taking the time to make sure everything was working perfectly before he left. He really went above and beyond and made the whole process completely hassle-free. I would not hesitate to recommend him and would happily use his services again in the future.Verified reviewerJob location: N810 Doors Opened / Unlocked

Excellent locksmith!
Laurence was fantastic when I got locked out of my flat, very good communication and advice on the job with up front explanations of costs. Very polite and professional. He attended very quickly and got me back inside with no trouble. Have saved his details and would definitely use his services again (though would hope don’t have the need!)Verified reviewerJob location: NW1
