About Time is available for local grandfather clock setup and servicing as well as talking customers through the process should they want to do it themselves!
Your clock will tell you when it is time for service. It will start having problems, like not striking or chiming, or the timekeeping will be erratic. A suddenly fast rate could be an indication of power loss due to dry, dirty oils and wear. Of course, if it doesn't run at all, it is certainly time!
