You won't find legal, insurance, engineering or tax advice here. Each cost figure shows where it came from and the year, and the national ones say so. Your actual price belongs to a contractor who has been in your basement, written down on paper.

Permit, sewer and licensing rules shift over time. When a page summarizes something from the City of St. Louis, St. Louis County, a municipality, MSD or the State of Missouri, check with that office before you act. None of those bodies endorses, funds or partners with this site.

Rainfall and flood facts cite the National Weather Service or a named news outlet, for context and nothing more.

The cost calculator and the wet-basement checker give ballpark, general answers. They have never seen your house and don't diagnose problems.

Each contractor receiving a request is a separate, independent business. The site gives no guarantee for any of them and bears no responsibility for their pricing, workmanship or behavior. Advertising bought by contractors may fund the site, while homeowners pay nothing and get nothing from it. As for insurance, plenty of homeowners policies exclude sewer backups without an added endorsement and often exclude seepage too; your policy, insurer or agent has the real answer.

Missouri law governs this disclaimer.
