If your piano has a reduced dynamic range, is less responsive than it should be or has sticky notes, we advise you to have your piano regulated. Uneven key heights can also indicate that regulation is required.


More severe problems such as a sluggish action or hammers with deep grooves in them require more intensive repairs to be carried out. Get in touch with us and we can provide you with a quote for any work that needs doing.


Regulation of a piano involves adjusting the many mechanical parts that are found in the piano action. These adjustments compensate for the effects of general wear that are caused by usage, such as the settling and compaction of cloth and felt. These parts can also be affected by atmospheric changes.


There are three systems that are adjusted during a piano regulation, the playing action, the pedal trapwork and the damper system.


The action is compromised of over 9,000 parts which are adjusted to critical tolerances to provide a fast and sensitive response to the pianist.


The pedal trapwork is comprised of a number of levers, springs and dowels that connect the pedals to the action, allowing the pianist to change the sustain and dynamics of the piano.


The damper system stops the vibration of the string when the key or pedal is released.

Why do I need to regulate my piano?


Regulating your piano ensures that has the best possible touch and responsiveness in the action, and that your piano has the broadest dynamic range.
