When you buy a used grand, the condition of a few key parts matters far more than the year it was built: the soundboard, the pinblock and tuning pins, the bridges, the strings and the action decide how it sounds and what it will cost you afterward. A structured viewing weeds out many bad offers, and for anything beyond a low-value instrument an independent piano technician should inspect it before you pay. The expensive problems (soundboard, pinblock, cast-iron plate) are rarely worth repairing; the cheap ones (tuning, regulation, voicing) usually are.
Age and condition are two different questions
A serial number only tells you when the piano was built, not what it is worth or how it has been treated. Manufacturers publish serial-number tables that let you date most grands. What counts is how the instrument has lived: steady room conditions, regular tuning and servicing beat a younger piano that stood next to a heater or went unserviced for years.
As a rule of thumb, hammers are filed after about five years of use and replaced every 10 to 15 years with frequent playing, key bushings wear out after about 20 years, and a full overhaul comes up within 40 to 60 years. A 40-year-old grand that has never been reworked will probably need work; one with documented, professional work can be a good buy. What "rebuilt" really means is covered in restored, original or rebuilt.
Very old grands (roughly before 1920) often still have a Viennese-style action. It is outdated to play, repeats notes poorly, and these pianos may have been built for a lower pitch, so they are rarely a good choice for beginners or students. Pianos from before about 1960 should also not contain plastic action parts, which can turn brittle over time.
Before the viewing: records and questions for the seller
- Note make, model, serial number and length. Does the length fit your room? See choosing the right grand piano length for your room.
- Ask for receipts and records: when was it last tuned, regulated and voiced? Has it been restrung, rehammered, or had soundboard work?
- Ask where it has been kept: living room, school, church, basement, storage? Any water damage, moves or renovations nearby?
- Long gaps between tunings or no records at all point to neglect.
- Take your time. An hour or two is realistic if you play across the whole keyboard.
The inspection checklist
Case, finish and surroundings
Look at where the piano stands first. Dark water marks, swollen veneer, a musty smell, rust on metal parts or loose cabinet joints suggest moisture damage that is not "just cosmetic". Scratches in the finish are a matter of taste, but a refinish is labor-intensive and costs several thousand dollars. Check the legs, casters and the pedal lyre as well: everything must sit firmly, and nothing should wobble or bind.
Soundboard and ribs
With a flashlight, look between the strings from above and, if you can, at the underside. A few fine cracks running with the grain are common and not automatically a problem. Many cracks, ribs coming loose, buzzing or rattling on certain notes, or a tone that stays dull and short even when the piano is in tune are more serious. How to judge them is covered in assessing soundboard cracks in a grand piano. Replacing a soundboard is expensive and only makes sense for high-grade instruments.
Pinblock and tuning pins
The pinblock holds the tuning pins that the strings are wound on. If the pins are loose, the piano keeps going out of tune or cannot be tuned cleanly, and fixing it often means restringing the whole piano. That makes it one of the most consequential findings in any inspection. Warning signs:
- Badly mistuned unisons (several strings per note that should sound identical), especially after a recent tuning.
- Dark, gummy stains around the pins, which can come from products used to tighten them temporarily.
- The piano will not hold standard pitch (A4 = 440 Hz) or sits well below it.
- Cracks or delamination visible on the underside of the pinblock.
You can only judge this roughly. Leave pin testing to the technician and do not try turning pins yourself.
Bridges, strings and the plate
Fine hairline cracks around the bridge pins are normal. Many cracks, especially on the bass bridge, or pins that have shifted are a big problem; a bridge repair can cost as much as the piano is worth. A loose bass bridge shows up as weak, dull bass notes. Rusty strings, missing strings or many splices point to frequent breakage, and if more than a few strings need replacing you are quickly looking at a full restring. The cast-iron plate must not be cracked: a cracked plate is practically a deal-breaker because the repair is rarely sensible.
Hammers and felt
Hammer heads should be rounded and taper toward the top. Flattened heads, deep string grooves or felt worn through to the wood mean they need filing or replacement. Moth damage on hammer and damper felt (tiny holes, grazed felt, dust residue) can require replacing the felt completely. Hammers that wobble sideways, loose parts or clicking noises point to a worn action.
Action and touch
Play each key on its own and in fast runs. A healthy action shows even key height, no sticking, no wobbling, even resistance from bass to treble, clean repetition and quiet playing on every key. Uneven or hanging keys are usually just a regulation job and fixable. A sluggish action or noises from inside suggest wear, moisture or pests.
Dampers and pedals
The right pedal (sustain) should lift all dampers evenly and drop them cleanly onto the strings with no ringing or buzzing on release. Try the left pedal, which shifts the action slightly, and the middle pedal if there is one. None should squeak, stick or feel loose.
Tuning stability and tone across the range
Do not judge the sound before the piano is tuned. An out-of-tune grand sounds worse than it is, and a freshly tuned one can sound better than it will stay. If a tuning is offered, ask whether it holds for a few days. When playing, work through this:
- Play every note individually and listen for buzzing, rattling, dullness and notes that die away unusually fast.
- Compare bass, middle and treble. The transition from wound to plain strings should not have a tonal break.
- Play softly and loudly: does the tone stay clean at high volume or turn harsh?
- Play chords in different registers to hear tuning and balance.
- Test sustain: a struck note should ring for several seconds (a common benchmark is at least roughly five seconds).
- Play a piece you know well and, if possible, try a second piano for comparison.
The room shapes the impression strongly: in a showroom with hard surfaces, bright pianos sound brilliant, but at home they can quickly turn shrill. If you can, try the piano in your own room or account for the room effect.
Warning signs and deal-breakers
| Finding | Assessment |
|---|---|
| Cracked cast-iron plate | Practically a deal-breaker; repair rarely sensible or guaranteed |
| Loose tuning pins, cracked pinblock | Very expensive, often restringing; only economic for high-grade instruments |
| Heavily cracked soundboard, separated ribs | Technician report needed; repair is extensive |
| Cracked or loose bass bridge | Expensive; compare cost with the instrument's value |
| Water damage, mold, rust, pests | Serious, not "just cosmetic" |
| Rusty strings, many splices | Restringing likely |
| Plastic action parts in pianos from before about 1960 | Risk, better avoided |
| Out of tune, uneven or hanging keys, uneven voicing | Usually fixable |
| Worn hammers | Moderate to high cost, factor into the offer |
When to hire a technician
Almost always, once the piano costs more than a few thousand dollars or you do not know its history. A technician checks what you cannot see: the pinblock from below, pin tightness, bridge condition, action wear and the soundboard. A pre-purchase evaluation in the US typically runs about $50 to $200, with one shop charging $125 (Oct. 2026), and the fee is small compared with the cost of a bad buy. Dealer pianos often include servicing, tuning and a warranty; this is part of the price premium and can reduce both inspection effort and risk.
Price logic and negotiation
A low price is only low if the total adds up: purchase price plus moving (transport and setup), tuning after the move, needed repairs and humidity control. If an inspection documents defects, use the repair costs as a negotiating argument. For orientation on repairs in the US (shop price lists, as of Oct. 2026): a full restring runs from about $2,500, replacing wound bass strings about $850, and replacement action parts sets about $750 to $3,100 depending on the component; full in-home regulation about $700 and general repair labor around $75 per hour. Refinishing costs several thousand dollars. Regulation, voicing and restringing prices vary by shop, so get a quote. As a rough rule, a thorough restoration quickly costs as much as a modest new piano; repairs only pay off if the piano is worth correspondingly more afterward.

Common mistakes when buying used
- Judging the sound before tuning: an out-of-tune grand gets rated too harshly or too kindly.
- Buying without an independent inspection because the seller is a "tuner" or the piano looks cared for.
- Confusing age with value: the build year says nothing about condition or market price.
- Forgetting follow-up costs: moving, tuning after the move, regulation, humidity control.
- Dismissing water or climate damage as a cosmetic flaw.
- Underestimating overhaul costs or choosing on price alone.
- Ignoring the room: do size and tonal character suit your space?
- Not getting the seller's promises in writing (condition, repairs, warranty).
Maintenance costs after you buy
Plan on tuning at least once a year, preferably twice. A grand tuning in the US typically costs about $165 to $240 (as of Oct. 2026), with a pitch raise adding roughly $40 to $80 if the piano has drifted well below pitch. A first-year schedule of four tunings is common for new or newly moved pianos while they settle in. Regulation (balancing the action) and voicing (shaping the hammer felt to even out tone) are separate jobs and not part of a tuning; they typically come due every few years. A relative humidity around 42 % at about 68 °F is a common ideal, and steady conditions protect the soundboard and pinblock most.
Depreciation and resale
Used grands lose less value than new ones, but a dealer's buying price sits well below their selling price, because the dealer has to cover repairs, storage and margin. Well-kept, high-grade instruments hold their value better; neglected ones lose it faster. Buy a piano with a traceable service history and do not treat resale value as a safe investment. Resale values vary a lot by make and condition, so get a few offers if you plan to sell.
