How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for New Jersey using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. New Jersey's RPP is 1.1 (national baseline = 100) and its BLS labor adjustment factor is 1.17. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(New Jersey) = 1.1 · BLS adj = 1.17

COMMON MISTAKE
Cleaning the mold without fixing the water means it comes right back.
- 2
Seal off the area so spores do not spread during cleanup.
- 3
Remove porous materials like soaked drywall and insulation that cannot be cleaned.
- 4
Clean and treat the remaining surfaces, then HEPA vacuum.
- 5
Dry the space fully and control humidity to prevent regrowth.
