What defects can be found in a used piano and how to repair them?

Purchasing a used piano can be a fantastic opportunity to own an instrument with a rich history and distinctive sound. However, older pianos may come with hidden surprises. Piano repair is often necessary for older instruments. Before deciding on a used piano purchase, it’s important to understand the potential issues and how to address them. This article aims to outline the most common problems found in used pianos, detailing repair methods from simple to complex. With this knowledge, you can make an informed purchase and ensure your piano serves you for many years to come.

Can old pianos be repaired?

Yes, old pianos can be repaired, a process commonly referred to as restoration. Restoration may involve acoustic repairs (soundboard, iron frame, bridges, pinblock) as well as cabinet repairs (veneer damage, refinishing). Virtually every problem occurring in the instrument can be solved. Some companies also offer to convert the upper damper mechanism to a lower damper, which improves the precision of the instrument. A well-conducted restoration can make an old instrument playable again and enjoyable for years to come. It’s also important to remember that regular maintenance is key to keeping a piano in good condition.

The most common defects found in used pianos

Check these common defects to ensure the chosen piano will provide beautiful sound for years to come. Most of these issues are relatively easy to fix. For piano repair, your local specialist can assist you.

  • Scratches and cabinet defects: These are usually easy to fix with filling, refinishing, or polishing.
  • Missing key veneers: These can be replaced with synthetic veneers in ivory or black.
  • Missing, broken, or tarnished strings: Strings can be replaced, but it may affect tuning and tone quality. In such cases, consider replacing all strings to ensure consistent sound quality.
  • Loose tuning pins: These pins secure the strings and loose pins cause detuning. They can be tightened with special glue or replaced with slightly larger pins.
  • Cracked soundboard: This can cause buzzing but may be repaired by securing ribs with the help of a technician.
  • Worn felt on hammers: Layers of felt can sometimes be carefully shaved to create a smooth surface, though this reduces the amount of felt available for future adjustments.

More serious defects – difficult or expensive to repair

  • Cracked pinblock: This is the part that holds the tuning pins. Its replacement is quite expensive. Loose tuning pins may indicate pinblock issues.
  • Damaged piano bridges: Their repair and reconstruction require extensive work, involving the removal of many components.
  • Broken or worn hammers: Replacing hammers can be costly, especially if they are damaged, worn down to the wood, or heavily moth-eaten.
  • Cracked iron frame: Not all cracks can be repaired, and fixing them requires specialized professionals willing to take on the challenge.

How much does piano repair cost?

The cost of piano repair usually varies widely, depending on the scope of the work and the type of defects. A general overhaul of a piano can cost from $4,000 and up. Smaller piano repairs, such as removing scratches, replacing key linings or individual strings, will be much cheaper. It is worth remembering, however, that a piano overhaul is usually more expensive than a piano overhaul.

Is it worth restoring old pianos?

Many experts believe that it is worthwhile to renovate old pianos, especially those manufactured before 1950. These instruments were built with high-quality materials, and their workmanship was very precise. Renovation preserves the quality of these instruments. In addition, a restored piano will become a unique piece of interior design. In addition to practical issues, restoration often has a sentimental dimension, because for many people a piano is more than just a piece of furniture.
