    Great workmanship and friendly, efficient service

    Posted 19 January

    Mark changed the locks when we bought our new home. He was really quick at responding to my messages and kept me well informed. The quality of his work was excellent, he was very tidy and left everything clean. He was also really knowledgeable, friendly and gave me great advice. I will definitely be recommending him to friends.

    Urgent repair when front door lock broke

    Posted 08 January

    Front door wouldn't lock when key barrell broke. Phoned Mark and was here in an hour. Fixed door on the spot and gave options and advice as he worked through the repair. Quoted price range upfront and final cost was within range. Big thanks to Mark and would thoroughly recommend his services.
