What the Boise average buys, as arithmetic on the guide's per-square-foot rates: about 2,968 sq ft of clean-water work at $3.50, 1,978 sq ft of gray water at $5.25, or 1,385 sq ft of black water, the category that includes sewage, at $7.50. The guide's rates are national; it does not print a separate per-square-foot rate for Boise.

Idaho is not one of the 5 jurisdictions whose mold licensing law this site has read (FL, TX, NY, LA and DC), so no state rule is shown here. That is not a finding that Idaho has none; the state's licensing board is the place to ask.

For scale, the Insurance Information Institute reports an average homeowners water damage and freezing claim of $15,400 for 2019-2023. The Boise average is 67% of that figure; claims include repairs and contents, not only drying.
