Clocks That Shouldn't Be Cleaned
Depending on the maker of the clock (as well as its age and the quality of the replacement pieces used), your clock can go from three to 15 years between servicing. Quartz clocks do not need any form of regular maintenance cleaning or lubrication as they are not powered with springs and gears.
Cuckoo Clocks
Cuckoo clocks are composed of a clock face, pendulums and an opening where a "cuckoo" bird emerges on the hour to chirp the time. Cleaning these clocks is complicated because of the weights used in the movement, as well as the intricate bellows that make the cuckoo sound. Expect to pay $375 to clean and lubricate the clock. If the bellows and gears need to be replaced, the cost can exceed that figure by as much as $100.
Atmos Clocks
Reutter's and Jaeger-LeCoutre Atmos clocks do not require mechanical winding and function based on changes in barometric pressure. The parts for these sleek clocks are quite expensive, so expect to pay $450 for a cleaning and servicing. Because they are precision clocks, you can go 15 years between services.
American Antique Clocks
Antique American clocks come from many manufacturers and range in style from schoolhouse clocks to mantel clocks to shelf clocks. The average cost of cleaning the faces, cases, face-glass and internal movements can range from $375 to $475.
Hourly In-Home Pricing
Some clock cleaning services can be performed in your own home. If the technician comes to you, expect to be charged for a minimum of one hour of service. Each hour of the clock specialist's time is likely to cost around $75, though that figure may vary depending on your geographic location and the needs of your particular clock.
