It is not possible to give a general answer here, as this depends on the type of instrument and its condition. Therefore, we can only provide a cost estimate after viewing the instrument.

The minimum of work includes: Dismantling the mechanics, cleaning the wood and tone holes, oiling the wood, cleaning and polishing the keys, making the mechanics playable. If required, we can replace cork tenons, damping corks and pads. Then assemble and play the instrument.
