Summer is the busiest season for moving in Toronto, but the intense heat and soaring humidity pose severe risks to acoustic pianos. When a piano is moved from an air-conditioned home into a sweltering moving truck, the sudden temperature spike can cause the soundboard to swell and the strings to stretch, instantly knocking the piano wildly out of tune. More dangerously, extreme heat can melt the specialized glues holding the action parts together. This is why Piano Movers Toronto utilizes fully climate-controlled transport vehicles. Our trucks maintain a stable 20°C and 45% relative humidity, ensuring your instrument arrives in perfect condition.
The Dangers of High Humidity
A piano is primarily constructed of wood, felt, and metal. High summer humidity causes the soundboard (the heart of the piano) to expand, which dramatically increases the tension on the strings and causes the pitch to go sharp. In addition, the felt bushings inside the action absorb moisture and swell, leading to sticky or sluggish keys.
Why General Movers Risk Your Instrument
General moving companies use standard box trucks. On a 30°C July day in Toronto, the inside of a metal box truck can reach a blistering 50°C. This extreme heat can literally melt the animal hide glue used in older pianos, causing veneer to peel and internal action parts to detach. Furthermore, standard movers often lack thick, specialized piano padding to insulate the instrument from these temperature shocks.
The Climate-Controlled Advantage
At Piano Movers Toronto, our entire fleet is equipped with state-of-the-art climate control systems. Your piano is first swaddled in heavy-duty quilted blankets for physical and thermal insulation, and then loaded into a temperature and humidity-regulated environment. We ensure the transition from your old home to your new home is seamless and completely safe.
