Read nothing here as legal, insurance, engineering or tax advice. Every cost figure is labeled with where it came from and the year, and national ranges say so. A real price for your basement comes only from a contractor's written estimate, made after seeing the space.

Laws, permit rules and public programs change. Where a page sums up material from MHIC, the Maryland State Board of Plumbing, the Attorney General, Baltimore City DPW or DHCD, Baltimore County PAI or DPWT, or another public body, confirm it with that office before acting on it. This site stands apart from every one of those offices; none endorses it, and none works with it. The Expedited Reimbursement Program and SOS Cleanup are Baltimore City programs for City addresses only, run on the City's own terms.

Storm and flood details name their source, such as Maryland Sea Grant, the Maryland Geological Survey or a news outlet, and are there for background only.

The wet-basement checker and the cost calculator return rough, general results. Neither one can see your walls or tell you what is wrong with them.

Any contractor that receives a request runs its own independent business, and this site takes no responsibility for its estimates, workmanship or conduct. Contractors may pay for advertising; homeowners are never charged and never receive anything. Insurance sits outside the site's role. Coverage for sewage backing up often requires a separate endorsement and slow seepage is often left out, so read your own policy and raise questions with your insurer or agent.

Maryland law governs this disclaimer.
