    Window lock repair

    Posted 05 August

    I found Certified Locksmith through Checkatrade. Laurence has done a great job. I had issue with UPVC window lock with the key stuck inside. He quickly replaced it with a new handle and lock. . He was very professional and efficient. He kept me updated on the arrival time. I can highly recommend Laurence and his expertise. 10 out of 10 from me :)

    Lawrence was fantastic. Really responsive, friendly and took the time to talk us through the different options without making us feel forced or rushed. Would highly recommend for anyone needing a reliable locksmith.

    I had a great experience with Laurence. He communicated clearly about pricing and availability upfront, kept me up to date on his arrival time and resolved the issue swiftly. I would recommend him and use him again for his services.
