Methodology

This page says where the figures on Corvant Water Damage Guide come from.

Population and county names come from the U.S. Census Bureau, Population Estimates Vintage 2025. The share of homes built before 1970 comes from the U.S. Census Bureau, American Community Survey 2024 (ACS 2024). When a national cost range is adjusted for the local price level, that level comes from the U.S. Bureau of Economic Analysis, regional price parities for 2024 (BEA 2024).

Typical job prices are drawn from open published data and from surveys of contractors. A range is a general guide for comparing jobs. It is not a quote for your home. Your price depends on the work, access, materials, and the company you hire.

The company list is built from open sources and from submissions sent by visitors. We may decline a submission, and we do not visit each business or confirm every license and insurance policy.
