I was not certain that our piano, which had not been tuned in years, would ever sound good again. Mr. Robertson is a gem! He respected our home, talked to our senior dog, then inspected the instrument, explained what was needed, and performed his piano-tuning magic. When he was finished, he played the piano beautifully. I highly recommend Mr. Robertson's work!

I was impressed with Calvin's patience working on an old piano that hadn't been tuned in over 10 years. It took all morning, but he explained why the strings were so challenging to tune. Calvin was completely professional and focused throughout his work. When he was finished tuning it, he played it and tested it, and found two stuck keys. I appreciated that he also fixed those before he left!

Details: Spinet • Last piano tuning more than 2 years ago • Piano played at least once month • More than 10 years old

Mr. Robertson was attentive to detail, thoroughgoing in approach, and did a masterful job on a 70 year old piano that had not been tuned for several years. I recommend him highly and without reservations. Jay

Pleasant, efficient, professional. Non-judgmental about the condition of my old piano, which had not been tuned in many many years!

Calvin was the consummate expert, and a polished technician. He arrived, excited and ready to go despite poor weather and travel conditions. He worked for nearly 90 minutes to lift pitch and tune a fine instrument that was badly out. I can only say that he really knows what he is doing as the instrument has continued to adjust to the process. My piano has yielded even further improved sonority and brilliance of tone in the days following his tuning.

Details: Upright • Last piano tuning 1-2 years ago • Piano played at least once a week • 2 - 5 years old
