Our Piano Services
An action (whether upright or grand) consists of over 4000 working parts not including the keys, strings or any other parts. Most of these are wool felts and bushings that are highly susceptible to moisture, moth and roach infestation,

Roaches, Rodents and Rug-rats
. In addition, these parts wear with age necessitating repairs.
New hammers are necessary when the grooves from playing a piano cut too deep to resurface.
Sometimes it is better to replace hammers along with their shanks and flanges.
Likewise, when many repairs are needed within the heart of the action, usually from years of neglect, entire whippen assemblies may need to be replaced.
Many points of contact should be lubricated with graphite, dag-graphite of centre pin lubricant. Once all the repairs are completed the keys may be leveled and the action regulated.
