Every agreement for commercial snow removal in Seattle answers one question first: who carries the risk of a mild winter and a hard one? Per-event and seasonal contracts split that risk differently.

How Snow Removal Contracts Are Structured

Per-event contracts

You pay a set price each time crews are dispatched, usually tiered by the amount of snow or by service type, such as pre-treatment, plowing or de-icing. If the winter is quiet, you pay little. If it is not, the bill rises with every storm.

Best for: lower-traffic sites, properties with flexible hours, and owners who would rather pay for what happens than for what might.

Seasonal contracts

You pay a fixed monthly or total amount for the season, whatever the number of storms. The vendor carries the risk of a heavy winter, and you carry the risk of paying for a mild one.

Best for: retail, logistics and multi-site portfolios that must forecast snow budgets a year ahead and cannot absorb a surprise invoice.

Hybrid and ice-only agreements

A common middle path is a seasonal base for ice management with per-event plowing on top. In Seattle, where freezes outnumber deep snowfalls, an ice-management-only contract fits sites that rarely reach a plow trigger.

What to Put in Writing Either Way

  • Trigger depth and what counts as an ice event.
  • Response window, such as lots clear before opening.
  • Scope: lots, walkways, ramps, hauling and repeat applications.
  • Season cap or snowfall ceiling on seasonal agreements, and what happens above it.
  • Documentation: arrival times, photos, product and area treated.
  • Insurance: certificate and additional insured status.

Choosing Between Them

If a closed lot costs you more than the contract, choose the structure that guarantees crews are staged. If you manage many small sites with uneven risk, mix the two. Before you sign, make sure you understand what the service itself includes. Anti-icing vs de-icing explains the work your contract should specify.
