Repairs & Cleaning

Some pianos are fairly clean and might need only a light cleaning of the soundboard and action.

Some pianos require a more in-depth cleaning under the keys and inside the piano.  You can discuss with Judy how in-depth you want the cleaning. The fee is charged hourly and the job can take 1-4 hours. Other services such as cleaning the action, sound board and interior, or repairs of worn out or broken parts are available.


Every piano has its own unique sound. One might be described as “glassy”, another as “warm”. One might have a “full singing” tone, and yet another sounds “thin”.
