I brought in my mother-in-law's clock when I inherited it and was very pleased with the service it received.
The clock is a wall clock, but contains the mechanism of a very nice grandfather clock. I was pleased to learn that the clock was more valuable than I had anticipated.
The clock was serviced for about $150. This included a total cleaning and replacement of all worn parts and gears. $150 may sound like a lot, but considering I don' t have to bring it back in for another 30 years, that is quite a bargain!
It's been running great for several years now and keeps flawless time.
