  • Keep plumbing near existing lines to cut trenching cost.
  • Confirm parking requirements before design — some cities require a replacement space.
  • 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.
