Piano Repair & Restoration Services in the Bay Area
Every piano, no matter how well built, requires care over time. Keys wear down, hammers harden, regulation drifts, and mechanical parts fatigue with use and age. Left unaddressed, small issues compound into bigger ones that affect playability, tone, and long-term value. Sweet Sound Piano provides professional piano repair and restoration services throughout the Bay Area, working on instruments of all ages, makes, and conditions — from a single sticky key to a full mechanical overhaul.

What Piano Repair & Restoration Covers
Repair and restoration is a broad category, and the right approach depends entirely on the instrument. At Sweet Sound Piano, our technicians assess each piano individually before recommending any work. The most common services we perform include
Regulation
Regulation is the process of adjusting the mechanical components of the piano action — the interconnected system of keys, hammers, dampers, and levers — so that everything works together with consistent touch, response, and dynamic range. A piano that feels uneven, sluggish, or unpredictable to play is almost always an issue of regulation. We bring the action back into proper alignment and adjustment so the instrument responds the way it was designed to.
Mechanical Repairs
From broken strings and worn center pins to cracked key tops, loose tuning pins, and damaged pedal mechanisms — mechanical issues in a piano are common and almost always fixable. Our technicians diagnose the root cause rather than treating symptoms, and source quality replacement parts to restore the piano to proper function.
Hammer Alignment and Voicing
Hammers that are misaligned strike the strings at the wrong angle, affecting tone consistency and accelerating wear. Hammer alignment corrects the physical positioning so each hammer strikes cleanly. Voicing — the adjustment of hammer felt density through needling or hardening — goes one step further, shaping the tonal character of the instrument to be warmer, brighter, or more even across the keyboard.
Action Adjustments
Beyond full regulation, individual action adjustments address specific complaints: a key that won’t repeat properly, a note that doesn’t speak at soft dynamics, a hammer that blocks, or a damper that doesn’t lift cleanly. These targeted repairs restore the piano’s responsiveness without requiring a full regulation job.
Signs Your Piano Needs Repair
Piano problems don’t always announce themselves loudly. Some of the most common signs that your instrument needs attention include:
- Keys that stick, feel heavy, or don’t return properly
- Notes that won’t repeat at moderate or fast tempos
- Uneven touch or tone across the keyboard
- Buzzing, rattling, or unwanted resonance on certain notes
- A key that makes no sound, or sounds much softer than its neighbors
- Pedals that feel loose, sticky, or don’t engage cleanly
- Visible cracks, chips, or loose components in the cabinet or action
If something feels or sounds off, don’t wait. Minor issues are almost always easier and less expensive to address early.
Repair vs. Restoration: What's the Difference?
The terms are related but distinct. Repair addresses specific functional problems — a broken part, a regulation issue, a mechanical failure. Restoration is a more comprehensive process that returns an aging or neglected instrument to a significantly improved condition, often involving work across multiple systems: action, strings, pins, finish, and more.
For many pianos, especially older instruments that have been well used, a targeted combination of repair and restoration work delivers the best outcome. Our technicians will assess your piano, explain what they find, and give you a clear recommendation based on the instrument’s condition and your goals for it — whether that’s reliable everyday playability or returning a cherished vintage piano to its original standard.

FAQ
A tuning addresses pitch — it brings the strings back to standard pitch but doesn’t fix mechanical problems. If your piano has keys that stick, notes that don’t speak evenly, a sluggish action, or unusual sounds, those are repair issues that tuning won’t resolve. Our technicians assess the full condition of the instrument during a service visit and will let you know what’s needed.
Regulation is the adjustment of the piano’s action — the mechanical system that connects your finger to the hammer and string. Over time, the parts that make up the action wear, compress, and drift out of their optimal positions. Signs that regulation is needed include uneven key weight across the keyboard, notes that won’t repeat cleanly at speed, or a general feeling that the piano is harder to play than it used to be. A full regulation restores consistent, responsive touch across all 88 keys.
Yes. Broken strings are one of the most common repairs we perform. We source replacement strings matched to the instrument’s specifications and install them to manufacturer standards. After restringing, the affected notes will require several tunings over the following weeks as the new strings stretch and stabilize.
It depends on the scope of work. Minor repairs — a broken key, a sticking note, a loose pedal — can often be completed in a single visit. More involved work like full action regulation or hammer replacement takes longer and may require multiple appointments or shop time. We’ll give you a realistic timeline before any work begins.
In most cases, yes — especially for quality instruments from reputable manufacturers. The cost of repair and restoration is almost always significantly less than the cost of a comparable replacement piano. The right answer depends on the instrument’s make, condition, and sentimental or monetary value. Our technicians will give you an honest assessment so you can make an informed decision.
