    I’d highly recommend Laurence. Excellent communicator - responds quickly and clearly. Is clear about pricing. Door was tricky but he fixed it and explained what the issue was. Really helpful and lovely to work with.

    Laurence came and fitted my deadbolt lock, and now I can lock my room securely. The job was completed quickly and professionally. Laurence was very helpful, friendly, and did an excellent job. Highly recommended!

    Excellent work fitting locks

    Posted 27 October

    Laurence fitted a lock to the side gate and another to the pocket door in the newly constructed extension. He was reliable and punctual, and has a professional approach to his work. He takes great pride in his work and did a sterling job. He took great care to explain thoroughly how to operate both locks afterwards. His work is excellent and I would not hesitate to recommend his services.
