  • Choose a metered unit; it uses 30–50% less salt than a timer model.
  • Collect three written bids on an identical scope — spreads of 20–40% are normal.
  • Book in the off-season and stay flexible on the start date to save 5–15%.
  • Bundle nearby work into one mobilization so you only pay setup and travel once.
  • Ask what the contractor would change to cut 10% without hurting durability.
