“Our front door rim lock didn’t comply with house insurance requirements. After checking with David he recommended the fitting of an additional mortise deadlock to BS3621. David arrived at the agreed time and carried out the work in a very professional and tidy manner. The cost of the work was as per quotation. I would definitely use David again for any future lock related work, he is to be highly recommended.”
