I gave an earlier poor review. While it took a while to complete, the clock is now functioning well. There were a series of missteps. However, in order to finalise the issue, the clock maker made the effort (twice) to come to our home to review the clock in situ and then later to finally install the clock. That's made the difference. Also, while at our home, he identified that the surface the clock was sitting on wasn't perfectly level (a very big issue with mantle clocks it seems). So, in summary, I've revised my opinion. It's not the fastest service, but he's a clearly a competent clock maker.
