How We Restore Pianos – The Complete Process
How to Check Piano Condition
Before starting restoration, it’s important to evaluate every part of the piano. This step helps identify existing problems that could affect both the repair process and the final outcome.
Basic Visual Check
Start by examining the piano’s exterior and pressing each key to spot any damage or unusual sounds. According to Piano World Memphis [2], issues like buzzing, harsh tones, or silence when pressing a key may signal internal problems.
Here are some things to watch for:
- Chipped or cracked keys
- Discolored or damaged finish
- Signs of water damage or rust
- Warped or split wood
- Missing or broken parts
Once you’ve completed the visual inspection, move on to testing the piano’s key components.
"The easiest place to start when checking the condition of a piano is with the keys." – Piano World Memphis [2]
Testing Major Parts
Check the main components of the piano systematically. Professionals usually focus on these areas:
| Component | What to Check | Warning Signs |
|---|---|---|
| Soundboard | Structural integrity | Cracks, warping, or damage |
| Pinblock | Stability of tuning pins | Loose pins or tuning instability |
| Hammers | Condition of felt | Worn felt or exposed wood |
| Action Mechanism | Responsiveness | Sluggish keys or sticking movement |
| Pedals | Functionality | Squeaky or unresponsive operation |
"The soundboard is the foundation of the piano. If the soundboard is cracked, warped or damaged, the rods will not move correctly, and the hammers and felts will work improperly, producing the wrong sound or no sound at all." – Piano World Memphis [2]
If you find significant issues during these checks, it’s wise to consult a professional.
Getting Expert Help
Professional assessments are crucial when dealing with persistent tuning problems, uneven tone quality, or multiple mechanical issues. Experts often perform detailed performance tests across various musical styles [1] and consider factors like the piano’s manufacturer and age to recommend the best restoration plan.
Some problems might not be obvious to an untrained eye. A professional evaluation can uncover hidden issues that could greatly influence the restoration process and final results.

Piano Restoration Steps
Restoring a piano involves a detailed, step-by-step process to ensure a professional result.
Taking Apart the Piano
Disassembling the piano is the first step and must be done carefully to avoid damaging components. It’s helpful to document each step with photos for smooth reassembly.
Here’s how professionals approach it:
| Component | Disassembly Step | Special Considerations |
|---|---|---|
| External Parts | Remove the key cover and lid, noting hinge positions | Record placement details |
| Action Components | Unscrew the action brackets and lift the mechanism | Handle with care to avoid damage |
| Keys | Remove keys one at a time | Label each key to track its position |
| String System | Gradually release string tension | A critical safety step |
"Dismantling a piano requires patient work and you won’t be able to use the piano again because you’ll probably damage pieces while taking it apart." [8]
Once disassembled, vacuum the interior to clear out dust and debris [3].
Fixing Internal Parts
After disassembly, focus on repairing or replacing the internal mechanisms. For example, replacing hammers requires careful preparation:
- Pre-Installation Preparation: Ensure all components are cleaned and lubricated before installing new parts.
- Hammer Selection: Yamaha provides complete hammer/shank/flange sets for grand pianos, ensuring consistency and easier installation [9]. During installation, check alignment and strike points for accuracy.
"Whatever you decide – do it yourself or pre-hung – do not assume that the existing hammer set was installed correct." – Gene Nelson [9]
Refinishing the Case
Once the internal components are addressed, shift to the piano’s exterior. Refinishing requires careful preparation and precision. Here’s the process:
-
Surface Preparation
- Strip the finish down to bare wood.
- Avoid water-based stripping agents.
- Sand thoroughly between coats.
- Finish Application
Different finishes create distinct results:
| Finish Type | Characteristics | Best Use Case |
|---|---|---|
| Hand-Rubbed | Offers a deep, rich appearance | Ideal for high-end restorations |
| Lacquer | Provides a classic look | Suitable for most pianos |
| French Polish | Period-appropriate finish | Perfect for antique instruments |
"When you do a hand-rubbed finish the wood comes alive… With a sprayed-only finish, the wood is slightly obscured – but when you wet sand and hand-polish the finish, the wood comes alive – some woods will actually look three dimensional." – Dennis Chupp, Master Piano Craftsman [11]
Keep the environment stable with consistent temperature and humidity to protect the wood and achieve the best results [10].
After-Restoration Care
Taking care of your piano after restoration is key to preserving its sound and appearance. Proper upkeep helps protect your investment and ensures the restoration lasts.
Daily Care Tips
Keep your piano clean and protected with a few simple habits:
- Always play with clean hands to avoid dirtying the keys.
- Use a cover when the piano isn’t in use to shield it from dust and pet hair.
- Dust the exterior with a soft, dry cloth, and clean the keys gently with mild soap and water, wiping from front to back.
- Avoid touching the strings, as oils from your hands can lead to corrosion [12].
Stable room conditions also play a big role in daily maintenance.
Climate Control
Temperature and humidity changes can seriously affect your piano. The sweet spot for humidity is between 40% and 60% [14][15]. Too much moisture can swell the wood and make keys stick, while too little can dry it out, leading to cracks [14][15].
Here’s how to keep your piano safe:
- Use a hygrometer to keep tabs on humidity levels [13][14].
- Place your piano away from windows, heating vents, fireplaces, exterior walls, and direct sunlight [13][14].
Professional Maintenance
Regular check-ups by a professional are non-negotiable. With over 260 strings and 40,000 pounds of tension, a piano requires expert care to stay in tune and perform well [16].
"Tuning is necessary for all acoustic pianos. Regular tuning prevents minor issues from worsening. And just like skipping the dentist, the piano tuner can cause bigger problems and cost more in the long run." – Alice, Family Piano Co [16]
Plan for annual tunings, preferably in the same season each year, and consider more frequent tunings for recently restored pianos [16]. Booking your next appointment right after a service helps you stick to a schedule, keeping your piano in top shape for years to come.
