My name is Paul James, and I perform tunings, minor repairs and regulating work on all varieties of pianos in and around Cambridge.
It is generally recommended that pianos should be tuned on a regular basis at least once a year, but preferably twice (particularly if it is played regularly), for it to continue to perform optimally. Often a piano will suffer from occasional minor problems - creaks, squeaks, and wear and tear that affect the keys and action inside the instrument. These tend to diminish the pleasure of playing the piano, whether by weakening the tone, or by causing the mechanism to function badly. Poor regulation of the mechanism can also be responsible for a variety of problems in a piano's performance. However, these issues can very often be solved with minor adjustments to the mechanism and may be cured relatively quickly, without recourse to moving the piano to a workshop.
Taking these steps to regularly maintain a piano can keep it in perfect working order for decades - that's what I am here for!
