Local tip: Local code, permit fees, and how busy crews are this month move numbers as much as wage rates do.
What usually moves the number
- Scope surprises: duct repairs, panel upgrades, extra roof layers.
- How booked local crews are this season.
- Materials choices — we only nudge materials with a dampened regional factor. See methodology.
Getting quotes without the circus
- Screenshot our mid/low/high band.
- Ask three licensed, insured pros for written scopes.
- Compare exclusions — permits, haul-away, thermostats, flashing — before crowning a winner.
