Methodology

Project Cost Advisor uses structured baseline pricing, material ranges, regional multipliers, and installation assumptions to build planning-grade homeowner estimates.

Guide pages combine national reference ranges, cost-per-unit benchmarks, material comparisons, labor allocation patterns, and common hidden cost categories.

State pages layer regional placeholders such as labor modifiers, permit notes, weather impacts, and local adjustment commentary onto those baseline models. Calculators are simplified estimation tools and should be validated against local bids.
