    Emergency Locksmith Service

    Posted 3 days ago

    Prompt, Professional, and Highly Recommended

    He provided an efficient and highly professional service, demonstrating extensive technical expertise. He was courteous and took the time to explain the issue and the proposed solution clearly and patiently. His pricing was fair and transparent, and he arrived promptly as scheduled. I am extremely satisfied with the overall standard of service and would not hesitate to recommend him.

    Lock Repair

    Posted 18 June

    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.
