    Excellent customer service

    Excellent customer service, right from describing and confirming the job (changing two locks on my front door) through to completing the work. Would recommend.

    Repair Conservatory Window & door after break in.

    Posted 1 week ago

    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.

    Really clear communication and demonstrated exactly what was wrong with the lock. The problem was resolved quickly and I was recommended the most cost effective option. Would absolutely recommend!

    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.

    Communication with Laurence was great. Very clear and honest instructions. He visited the property this morning and did an amazing job getting the window to open. Highly recommend!
