Our Services

To keep your piano performing at its peak, we recommend professional tuning twice a year—or at least once annually. Regular maintenance prevents the pitch from dropping over time and ensures a consistent, high-quality playing experience.

Every tuning includes a complimentary assessment of your instrument. Minor adjustments and small repairs (those not requiring special parts or extensive labor) are included at no extra cost. For larger maintenance needs, we provide a detailed, transparent quote.

Consistent Care, Better Rates: We offer preferred pricing for clients who maintain a regular service schedule to keep their instruments in top condition.

Expert Concert-Level Piano Tuning

Professional precision for a stable, beautiful sound.

We reward consistent maintenance with straightforward, affordable rates starting at:

$120 + tax within 8 months of last tuning
$150 + tax within 14 months of last tuning

In Toronto, extreme seasonal shifts can cause a piano’s pitch to drop significantly. Without regular care, your instrument may fall far below Concert Pitch (440Hz), requiring extensive restoration.

The Advantage of Regular Care:

We keep our services accessible by including minor pitch adjustments in our base price. We do not charge extra for these adjustments unless significant time is required to stabilize an instrument that has been neglected for over a year or has dropped more than 10 cents flat.

Same-Day Pitch Restoration

Comprehensive care to bring neglected instruments back to life.

If your piano has dropped more than 10 cents flat, a Pitch Raise is required to restore its voice. To save you the cost and hassle of multiple appointments, we offer comprehensive same-day restoration starting at:

$180 + tax for 1.5 tunings equivalent
$220 + tax for 2 tunings equivalent
$300 + tax for 3+ tunings equivalent

Transparent On-Site Assessment:

Final pricing depends on the piano’s architecture and the duration of neglect. Upon arrival, I will provide a transparent assessment of the work needed to return your piano to standard pitch.

We welcome a collaborative consultation regarding your goals—whether you require a full restoration to 440Hz or a customized stable pitch based on the instrument's condition. Every option provides the same high-quality, harmonious sound and stability as our Expert Concert-Level Tuning.

Piano Repair & Regulation Service

Tailored solutions for your instrument’s mechanical needs.

We are happy to assist with any mechanical issues or performance adjustments your piano may require. To help you save on costs, we recommend addressing any concerns during your scheduled tuning session.

Transparent Quotes:

Provided upon request for all repair and regulation work.

Service Call Fee:

A $75 fee applies for standalone service visits; however, this fee is waived if you proceed with a repair contract.

Notes on Travel Charge

Service area and community bookings.

We provide service throughout the Greater Toronto Area, with no travel charges for locations within a 30-minute drive of Aurora, Ontario.

For destinations beyond this 30-minute radius, travel fees are flexible. To provide you with the best value, we may waive these charges if we have multiple customers in your area on the same day.

Save with a Group Booking:

We encourage clients to coordinate same-day appointments with neighbors or friends in their local community. Booking multiple tunings in one area allows us to waive travel fees and pass those savings directly to you.
