The mechanical condition of a piano defines its soul.
At The Pro Piano, our Mechanical Restoration & Voicing services are designed to restore the precision, responsiveness, and tonal character of your instrument. Whether you are a concert pianist or a dedicated student, we calibrate the internal "action" to match your specific musical touch and stylistic preferences.
Our certified Steinway & Yamaha technicians specialize in transforming instruments that feel "heavy," "sluggish," or "tonally uneven" back into world-class performance tools.
Professional Voicing & Tonal Development
Voicing is the art of adjusting the piano's tone by modifying the density of the hammer felts. Every pianist has a unique preference—ranging from a warm, European lyrical tone to a bright, powerful American projection.
Our Voicing Process Includes
Hammer Needling
Adjusting felt tension to remove harshness and "mellow" the sound.
Surface Filing
Reshaping worn, grooved hammers to restore clarity and tonal focus.
Chemical Hardening
Carefully increasing brilliance for pianos that sound dull or "tubby."
Tonal Leveling
Ensuring a seamless, balanced transition between the bass, tenor, and treble registers.
Precision Action Regulation
If your piano lacks control or sensitivity, it likely requires Regulation. This is the mechanical adjustment of the 9,000+ parts between the key and the hammer to ensure maximum efficiency and "repetition speed."
Optimizing Key Sensitivity
Correcting sluggish key response, uneven touch, or repairing broken keys to restore a consistent feel across the keyboard.
Noise & Vibration Elimination
Identifying and resolving the source of distracting internal vibrations, mechanical clicks, or metallic rattling sounds.
Hammer Let-off & Timing
Ensuring the hammer releases at the precise moment to improve pianissimo control and overall performance accuracy.
Key Leveling & Dip Adjustment
Calibrating all 88 keys to a uniform height and consistent downward travel (dip) for a balanced and comfortable playing experience.
Restoration & Overhaul
For heirloom or heavily used instruments, a full Mechanical Overhaul may be necessary to restore structural and musical integrity. Our restoration plans are custom-designed for each instrument:
- Action Rebuilding: Complete disassembly, cleaning, and re-bushing of the internal mechanisms.
- Component Replacement: Installing premium German Abel or Renner hammers, new dampers, and high-quality leather/felt components.
- String & Pinblock Care: Addressing rusted strings or loose tuning pins to ensure stable pitch.
- Structural Repairs: Repairing bridges or soundboard shimmying to restore resonance.
