Minor to Major repairs
Piano Regulation
aWhile tuning corrects the pitch of your piano, it is only one component of a complete maintenance program. Regulation pays attention to the touch and uniform responsiveness of your action - vital to making each performance pleasurable. In addition, regulation ensures that your instrument is capable of producing a wide dynamic range - a critical control factor, particularly when playing pianissimo (quietly).

Grand piano key repair
Most if not all piano have lead weights inserted in the keys as means of balancing the action. On older pianos lead can react with the salts in the air and start to expand or increase in size to a point where the keys will eventually crack.
This occurrence is called by many names including "Lead cancer" or "Lead rot" or "Lead bloom".
The first sign are sticky keys or even completely jammed keys.
A temporary repair is to cut off the protruding part of the lead, however often a complete lead replacement is necessary.
This is not a difficult repair, however it is time consuming.
Another common piano keys repair is the key top replacement.
This is due to age and mechanical ware, cracks, discolouration or general damage to the key tops.
Soundboard shimming & Strings
The soundboard is one of the most essential parts of your piano. When you play, the soundboard amplifies and radiates a large volume of sound into the air.
Solid spruce soundboards swell and shrink with seasonal changes in humidity and, over time, can develop cracks.
One of the problems that comes up most frequently in buying a used piano is judging the significance of a cracked soundboard.
Contrary to popular belief, cracks in the soundboard, while often unattractive, are not necessarily important, as long as the tone is acceptable. Very extensive cracking, however, can indicate that the piano has suffered great climatic extremes, and that its life expectancy may be short.
The quality of the tone the piano slowly changes as the piano ages. It looses its "bite" and "colour" as the strings age.
This loss of tonal quality can be partially corrected but it will never be the same as when this piano was new.
The first obvious sign is with the copper bass strings. There the tone quality becomes "tubby" or dull.
There are other pianos that keep breaking strings especially in the upper register.
So how do you know that your piano will benefit from new strings?
