Most people know something is wrong long before they know what to call it. A note stops sounding, a key sticks or stays down, the pedal loses its effect, the action feels uneven, or the instrument simply stops being dependable.
NPT turns those symptoms into a practical repair conversation. Pianos are the core of the workshop — uprights and grands, action and key work, regulation, rebuilding and full restoration — and the same diagnostic discipline extends to keyboards and digital pianos.
Where an instrument falls outside the piano family, we will say so honestly and tell you what is realistic rather than accept work we cannot do well.
