Grandfather Clocks

Grandfather clocks, like any other clock, need periodic maintenance to keep them in good running order. It has been my observation that most newer clocks will need to be cleaned @ 15 years on average. Older or antique clocks may run much longer but should still be cleaned @ 20 year intervals. Even the best modern oils will be breaking down by then.

Depending on operating conditions, a service call to oil the movement may be needed in the interim. Normally this would be no sooner than 7-10 years. Oiling the mechanism when it isn't called for can be just as detrimental to the movement as no oil at all. The right type of oil must be used, as oil properties vary widely depending on the application.

Some symptoms that might be noticed if your clock is in need of these type services would be:
Random stopping, may be able to restart.
Sluggish tempo of the chime or strike.
Timekeeping may become erratic or you may not be able to regulate it within the adjustment limits of the pendulum.

Grandfather clocks are the pride of every home. Entrusting their repair to someone that doesn't have the proper qualifications can greatly increase the cost to put things right again.
