There are many places to get a Seth Thomas clock repaired, including the Midcoast Clock and Music Box Company, Povall Clock Repair, Bill's Clock Works, Michael Gainey's Master Clock Repair and Heritage House Clocks. All of these establishments accept shipped projects, allowing for long distance repairs.
All of the above companies also offer a 1-2 year warranty on their work. Some Seth Thomas Clocks are too large to easily ship to a repair shop. The Midcoast Clock and Music Box Company will make a house call in certain states to fix these larger clocks. Prices vary widely in this business based not only on repairman but also on the condition of the clock needing to be repaired.
