In The Workshop

With over fifty 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. There are up to 25 steps in this process as follows:

  • Strip and sand the cabinet, furniture parts and bench.

  • Restore original key covering or replace.

  • Clean, sand, re-gild and dress the plate with the appropriate felts.

  • Remove and inspect the pin block (duplicate if needed).

  • Remove and inspect the under-lever tray.

  • Tighten the under-levers and check the felt bushings along with the damper guide rail.

  • Re-bush action parts as needed.
