Soundboard replacement is a process in piano restoration where the soundboard – the component that amplifies the vibrations of the piano strings – is replaced to restore or improve sound quality. It’s typically necessary when the soundboard is severely damaged, leading to muffled tones or tuning instability. Here’s a quick breakdown:
- When to Replace: Large cracks, loss of crown (curvature), buzzing sounds, or unstable tuning.
- Costs: Ranges from $11,000 to $22,000 for high-end brands like Steinway. Upright pianos may cost less, starting around $1,000.
- Process: Involves removing strings and the cast iron plate, installing a new pre-crowned soundboard, and restringing the piano.
- Signs of Damage: Cracks, detached ribs, bridge damage, or inconsistent sound quality.
- Repair vs. Replace: Repairs (e.g., crack fixing, shimming) cost $1,000–$8,000, while replacement offers long-term benefits for premium pianos.
Replacing a soundboard is a major investment, suitable for high-value pianos, while repairs may suffice for less expensive instruments.

Warning Signs of Soundboard Problems
Physical Damage Signs
Physical damage to a piano’s soundboard is often easy to spot. Cracks along the seams where the wood pieces meet are one of the most common signs of trouble [5]. Larger cracks may occur due to significant impacts [5].
Other signs of physical issues include:
- Detached ribs underneath the soundboard, which weaken its structure [3]
- Compression ridges at the joints of the soundboard planks [3]
- Bridge damage, sometimes caused by termites [4]
- Separation between the soundboard and rear bracing [5]
These physical problems can lead to noticeable changes in sound quality and tuning stability over time.
Sound Quality Issues
A damaged soundboard can drastically alter the piano’s sound. For example, if the crown (the natural curvature of the soundboard) is lost, you might notice:
- A narrower, less full tone
- Shorter sustain or decay
- Inconsistent sound across different registers [6]
Additionally, if the bridge or ribs separate, you may hear buzzing noises or experience a significant drop in performance in certain registers [6].
Tuning Stability Problems
Major soundboard problems can also make it harder to keep your piano in tune. Watch for these signs:
- Strings losing tension frequently, requiring constant tuning [5]
- Uneven downbearing, which can cause flatter sustain
- Unwanted noise, like rattling or buzzing, from separated wood pieces [5]
If you hear buzzing or rattling after playing specific notes, it’s time to call a professional piano technician [1]. This could mean the soundboard has split into separate sections and needs immediate attention.
Steps in Soundboard Replacement
Soundboard Removal Steps
Replacing a piano’s soundboard involves taking apart the instrument. This includes removing all strings and the cast iron plate to access the damaged board. During this process, technicians carefully measure and document reference points to ensure the piano is reassembled correctly and maintains its structural balance [7][8]. Once the damaged board is removed, the focus shifts to installing the new soundboard.
New Soundboard Installation
Modern techniques use pre-crowned, ribbed boards, making the installation process more efficient in workshop settings [8]. Many restoration shops, such as Bradfield Piano, rely on Bolduc soundboards, known for their high quality and compatibility with original piano designs [1].
"At Bradfield Piano, our experienced technicians apply advanced repair techniques to mend soundboard cracks and restore the instrument’s sound. If the soundboard has sustained extensive damage, we can remove the plate from the piano and replace the soundboard."
- Bradfield Piano [1]
The installation process includes several steps:
- Using a "hot box" to create a controlled environment for installation [8].
- Fitting the pre-crowned board to match the piano’s specifications.
- Installing support ribs while maintaining the proper crown.
- Securing the soundboard to achieve the best possible acoustic results.
Piano Restringing Process
After the soundboard is installed, the piano is restrung. This step is crucial for sound quality and the instrument’s lifespan. Restringing costs typically range from $2,000 to $4,000 for upright pianos and $4,000 to $10,000 for grand pianos [10].
Key steps in restringing include:
-
Pin Installation
Technicians often use larger tuning pins than the originals to improve stability in older pianos. A full set of new strings generally costs between $250 and $400 [9][10]. -
String Installation
Strings are measured, coiled, and tensioned with precision. Technicians ensure even tension, proper gauge selection, and accurate coil placement to avoid buzzing. -
Tuning and Stabilization
Multiple tuning sessions are required as the new strings stretch and settle. Professionals, like those at Cooper Piano, also perform custom voicing to help the piano adjust to its environment [2].
"The Cooper Piano restorative art is not just a cosmetic cover-up. Our restoration process can include the creation and replacement of the original soundboard and pin block by using the finest materials and the most exacting standards."

Next, let’s compare the costs of repairing versus replacing a soundboard.
Repair vs. Replace: Cost Analysis
When deciding between repairing or replacing a soundboard, consider these cost comparisons:
-
Repair Costs: Basic repairs usually range from $1,000 to $8,000 [11]. These often include:
- Fixing cracks
- Shimming
- Reattaching ribs
- Restoring the crown
- Replacement Advantages: A new soundboard can offer long-term benefits like better tuning stability, improved tone, and potentially higher piano value.
"Although, in theory, cracks and a loss of crown should result in a deterioration of tonal quality, the actual results vary greatly from piano to piano; therefore, the tone quality of each such instrument must be evaluated on its own merits." – Larry Fine [14]
- Cost-Saving Tips:
- If your piano is already being rebuilt, adding a new soundboard can be more economical. This typically increases the project cost by about $5,000 [12], compared to $8,000–$10,000 for a standalone replacement [12].
- Regular maintenance and controlling humidity levels can help avoid future damage.
