RepairGauge U.S. Home Repair Cost Index
The exact reference ranges used by RepairGauge calculators and cost guides. Every row links to a current source; where publishers disagree, we use a clearly disclosed cross-source planning range rather than pretend there is one universal price.

What this dataset is — and is not
These are national planning ranges assembled from current published cost guides. They are not local contractor bids and they are not represented as proprietary ZIP-level market data. State and ZIP do not alter calculator output until RepairGauge has enough reviewed local observations to support that claim.
