The Piano Restoration Process


25 Steps to Restoration

With over forty years of experience in restoring grand and baby grand pianos, we have had plenty of time to refine our meticulous process. We guarantee that you will be delighted with the results of our careful work as our craftsmen restore your piano according to our 25 step process as follows:

  • Disassemble the cabinet and parts.
  • Remove the cast iron plate.
  • Sand and refinish the bridges and soundboard.
  • Strip and sand the cabinet, furniture parts and bench.
  • Restore original key covering or replace.
  • Finish in the original color and sheen with 22 coats of lacquer.
  • Clean, sand, regild and dress the plate with the appropriate felts.
  • Remove and inspect the pin block (duplicate if needed).
  • Remove and inspect the underlever tray.
  • Tighten the underlevers and check the felt bushings along with the damper guide rail.
  • Rebush action parts as needed.
  • Reinstall and align the cast iron plate.
  • Set the down bearing and install new strings and tuning pins.
  • Chip tune the piano strings to concert pitch.
  • Remove original felt from the damper blocks and refinish.
  • Cut and install new damper felt.
  • Regulate dampers to the back of the key and the sustain pedal.
  • Shape, file and space the hammers.

  • Adjust let-off, drop, and back checks.
  • Tune piano in shop, repeatedly adding tension to concert pitch.
