A DIY check can help you quickly filter out obviously poor-condition pianos (e.g., broken keys, cracked case, rusted strings), but only a professional technician inspection can reveal hidden structural, mechanical, and tonal issues that determine whether the piano is truly playable and worth the investment.
DIY Checking (Self-Assessment by Buyer)
What You Can Do Yourself
-
Visual inspection: Look for cracks in the case, missing parts, water damage, or obvious warping.
-
Keys & pedals: Test every key for sticking, uneven touch, or dead notes; check pedals for smooth function.
-
Strings & tuning pins: Look for rust, corrosion, or loose pins.
-
Basic sound test: Play chords and scales to hear if the tone is even or if there are buzzing/rattling noises.
Limitations
-
You cannot accurately judge pinblock integrity, hammer wear, regulation precision, or subtle soundboard issues.
-
Cosmetic appearance can be misleading—many pianos look shiny outside but are worn inside.
-
DIY checks are useful for screening, but not for making a final decision.
Technician Inspection (Professional Evaluation)
What a Technician Can Do
-
Structural integrity: Assess soundboard, bridges, and pinblock for cracks, warping, or instability.
-
Action regulation: Measure key dip, hammer travel, let-off, and repetition speed.
-
Hammer & felt condition: Check for deep grooves, flattening, or moth damage.
-
Tuning stability: Test whether tuning pins hold pitch properly.
-
Humidity damage: Identify swelling, rust, or mold that may not be visible.
-
Repair cost estimate: Provide realistic costs for regulation, voicing, restringing, or rebuilding.
Advantages
-
Gives you a clear picture of long-term playability and costs.
-
Protects you from buying a piano that looks fine but is structurally unsound.
-
Provides leverage in price negotiation with sellers.
Practical Advice for HK Buyers
-
Use DIY checks to quickly filter out unsuitable pianos before arranging a professional visit.
-
Always hire a technician before finalizing a purchase, especially for private sales.
-
Consider the inspection fee as insurance—it can save you tens of thousands in future repairs.
DIY checking is a good first step to avoid wasting time, but only a technician’s inspection can confirm whether a piano is structurally sound, musically satisfying, and financially worth buying.
Consulting a piano technician over the phone can give you general guidance, but it cannot replace an in-person inspection, where the technician can physically test the piano’s structure, action, and tuning stability. Phone advice is limited to theory and assumptions, while hands-on inspection reveals the true condition and repair costs.
Limitations of Phone Consultation vs. In-Person Inspection
1. No Physical Testing
-
Over the phone, a technician cannot press keys, test pedals, or check action regulation.
-
Critical issues like sluggish repetition, uneven touch, or hammer misalignment are impossible to detect without hands-on testing.
2. Hidden Structural Problems Go Unnoticed
-
Soundboard cracks, bridge damage, and pinblock weakness are often invisible to the untrained eye.
-
Only by physically probing tuning pins and inspecting wood can a technician confirm if the piano will hold pitch.
3. Tone and Voicing Cannot Be Judged
-
A phone call cannot capture the subtle tonal qualities of the piano.
-
Even recordings are unreliable, since microphone quality and room acoustics distort the sound.
4. Humidity and Environmental Damage
-
In Hong Kong’s humid climate, pianos often suffer from rusted strings, swollen wood, or mold.
-
These issues are subtle and require close inspection with light and tools—something impossible over the phone.
5. Repair Cost Estimates Are Inaccurate
-
A technician can only give very general advice by phone.
-
Without seeing the actual instrument, they cannot provide a reliable estimate for regulation, voicing, restringing, or rebuilding.
6. Weaker Negotiation Leverage
-
A buyer armed only with phone advice has little proof when negotiating with a seller.
