Knowing exactly when to dispatch snow removal crews is a science that balances safety, cost, and contractual obligations.

Understanding trigger depths for snow removal is critical for both residential and commercial property owners. Most contracts specify a trigger of 2 to 5 centimetres, meaning removal begins once snowfall reaches that threshold. Choosing the right trigger depth depends on how your property functions and who uses it.

Winter Preparedness Tips

Commercial properties with heavy foot traffic or accessible parking often use a 2 cm trigger. This aggressive approach ensures ice buildup doesn't occur under foot traffic before crews arrive. Residential driveways typically use 5 cm, balancing costs while keeping pathways safe.

Time-based triggers are another common approach. Instead of measuring accumulation, crews are dispatched at set intervals during active snowfall. This works well for properties that need continuous access during storms, such as hospitals, grocery stores, or emergency facilities.

After-event triggers mean removal happens after a storm is completely finished. This is the most cost-effective option for properties closed overnight or during weekends, but it introduces risk if freezing temperatures lock in accumulated snow before crews arrive.

D&D Snow Services helps clients choose the right trigger strategy based on their property type, usage hours, liability concerns, and budget. Working with an experienced crew means your contract is built around your actual needs, not a one-size-fits-all approach.
