Repairing Piano Hammers

A broken, misaligned or damaged piano hammer can have a significant effect on your ability to play. Your instrument may have muffled voicing or some keys may fail to sound a note. Repairing the hammers and hammer shanks can restore the proper tones. For the highest-quality repair or replacement, work with an expert piano technician to rebuild and preserve your fine piano.

Why Repair Piano Hammers and Hammer Shanks?

Poor voicing and dead keys are easy-to-recognize problems that may link back to a damaged hammer. The density and resiliency of a hammer’s head impact how your piano sounds. A hammer head that is too dense creates a harsh tone, so it will need to be softened. If the head is not dense enough, you’ll experience muffled tones and will need to replace the head for a sharper sound.

When keys fail to sound a note, a broken or misaligned hammer mechanism could be the culprit. Your piano technician will replace or realign the hammer to reestablish the proper sounds. To protect your investment, we recommend regular maintenance of your piano hammers and hammer shanks.

Hire a Professional to Repair Your Piano Hammers

Repairing a piano hammer or hammer shank on your own could cost more time and money in the long run. DIY projects provide a quick fix, but the patched joint could break again and create a more significant issue. Repair sleeves also add weight to your entire action and make it tricky to adjust the hammer.

To repair or replace piano hammers correctly, hire a qualified professional. A trained piano technician can assess the head and shank and make any necessary repairs. More significant damage, such as a broken hammer, may call for a complete replacement. Work with a technician that uses only high-quality, genuine replacement parts to maintain your instrument’s authenticity.
