American Antique Clock Repair

We repair antique American clocks made by Ansonia, Gilbert, Ingraham, Jerome, New Haven, Sessions, Seth Thomas, Waterbury, Welch, and other makers. We believe in keeping your heirloom clock as original as possible, and replace parts only when necessary. We give a two year warranty on wind-up clock repair.

Bill's Clockworks is located in Flora, Indiana (about an hour north of Indianapolis). Besides local repair work, we are happy to have smaller clocks shipped to us for repair (such as mantel clocks and smaller shelf clocks). We are currently repairing pendulum clocks but not clocks with a balance wheel.

We take the time to repair your clock properly. The movement of your clock is disassembled, cleaned and examined. Mainsprings which are too strong are replaced with thinner springs to give your clock long life. The pivots are polished and worn pivot holes are bushed. Other necessary repairs are made and the parts cleaned again. Then the movement is assembled, lubricated, adjusted and tested.

Examples of our repair prices are shown below. The price will be higher if there are any damaged gears. At your request we will beautify your clock while keeping the finish original. For about $40 - $80 we will clean the case and touch up the finish. For $50 we will polish and lacquer the bezel of a mantel clock.

Our repair backlog is about 2 months. Please contact us about sending a clock for repair.

Packing for Shipping

Please send the key so I can check how well it fits. I will replace it if it is worn out (I will return the original to you). Please let me know if you need a key.

Before packing the clock, remove the pendulum bob and wrap it and the key in bubble wrap. Gently tape the pendulum rod to the movement to prevent motion, and put padding around the hammers, gong or chime rods inside the clock to immobilize them. On clocks with painted glass in the door, it is best to remove the door (and not send it to me) to prevend damage. Wrap the entire clock in several layers of bubble wrap. Use a box that gives 2 - 3 inches space around the wrapped clock on ALL sides. Put a 2 - 3 inch layer of foam packing peanuts in the bottom of the box. Put in the clock, and fill the space firmly with peanuts. Include the wrapped key and pendulum bob. There should be a slight pressure when closing the box to keep the clock from moving around.

Proper Mainsprings for American Antique Clocks

See my Clock Information Blog for more information about mainsprings for American clocks.

Bill’s Clockworks repairs your clock properly so that it will have a long life. Some repair shops are using mainsprings that are too strong for your clock. Here is some information about the proper springs for American antique clocks.

Some American clocks originally had thinner springs

Seth Thomas Clocks:

The popular Seth Thomas #89 mantel clock movement originally used 0.017" thick mainsprings. Some repair shops actually take these out and put in stronger springs (even when the originals are good!) We keep the originals in the clock if they are good. If a spring needs replacing (or has a replacement that is too strong), we install a 0.0165" thick mainspring.

Waterbury and Ansonia Clocks:

Popular Waterbury and Ansonia movements made from the 1880's through the 1920's originally used mainsprings 0.0145" to 0.016" thick. All too often, repairers install 0.018" mainsprings in these clocks! This causes quick wear to the mainwheel teeth. Bill's Clockworks installs the proper springs, to give your clock long life.
