3 cm vs 5 cm Snow Removal Triggers

A lower snow trigger can change how often a seasonal contractor may dispatch. Here is what the number actually means before you choose a package.

What is a snow-removal trigger?

A snow-removal trigger is the accumulation threshold written into the service agreement. Once the applicable threshold is met and the other contract conditions are satisfied, the property becomes eligible for service under that agreement. The trigger is not a promise that a truck will appear at the exact instant a ruler reaches that number; route operations still have to be dispatched and completed safely.

Why 3 cm and 5 cm service can feel different

A 3 cm trigger can result in service during lighter accumulations that would not yet meet a 5 cm threshold. Across an entire winter, that can mean more potential service events and a different routing commitment. A 5 cm trigger waits for more accumulation before the contractual threshold is reached.

Trigger versus municipal plowing

Municipalities use their own road and sidewalk service standards. Those thresholds do not control a private HSR agreement. Your private-property service is governed by the trigger and scope in the signed contract.

What should you compare when shopping?

Do not compare snow-removal quotes on price alone. Compare the trigger, areas included, whether salting is included or optional, route/service expectations, what happens during long storms, and how the contractor records or communicates completed service.
